In 2004, a Department of Health Study determined Bermuda's health pri-orities1 and identified heart disease and stroke as the number two health problem for the country. The 2006 Health Survey of Adults and Children in Bermuda revealed that 25% of adults reported they had high blood pressure2. Diseases of the cir-culatory system, of which high blood pressure is a major contributing factor, are the leading cause of death in Bermuda (43.4% of all deaths in 20073).
The 2008 National Health Promotion Strategy, Well Bermuda4, listed Improve Heart Health among the primary health promotion goals for the country. The Improve Heart Health objectives are to: 1. Reduce the proportion of adults with high blood pressure. 2. Reduce the proportion of adults with high total blood cholesterol 3. Increase the proportion of adults with high blood pressure whose blood pressure is under control.
4. Increase the proportion of adults who have had their blood pres- sure measured within the preceding year.
5. Increase the proportion of adults who are aware of the early warning symptoms and signs of a stroke.
To facilitate Government's goal for hypertension (high blood pressure), the then Minister of Health appointed a Task Group of representative stakeholders from Bermuda's health professionals in October 2010. The purpose of the Task Group was to provide a consultative forum to review clinical guidelines from recognized hypertension organizations overseas and to develop guidelines best suited to Bermuda's needs. The following five guidelines were reviewed: 1. Caribbean Health Research Council: Managing Hypertension in primary care in the Caribbean.

Web version. 2009.9 The Hypertension Guidelines for Bermuda represent the consensus of the Hypertension Task Group based on collective analysis, evaluation and opinion on the current information available to them. The information included throughout the guidelines is taken largely from the above five guidelines and additional referenced documents. These guidelines are designed to be easy to follow and serve as key tools in improving patient care.

MEASUREMENT OF BLOOD PRESSURE (BP)
Setting and Circumstance
• BP can be measured in the office, clinic, hospital, at home or with an ambulatory BP machine.
• No caffeine/tobacco or exercise 30 minutes prior to measurement.
• Rested for five minutes, seated in comfortable chair.
• Arm at heart level; back supported and feet on ground.
• Arm is bare.
• Room is warm and quiet.
• Recommend auscultatory method of BP measurement. • Use mercury sphygmomanometer, or calibrated aneroid, or validat- ed electronic device.
• Ensure appropriate cuff size – with the bladder encircling at least 80% of the circumference and covering 2/3 length of the arm.
• Note, a bladder that is too small may cause falsely high readings.
• Use bell of the stethoscope.
Recommended Dimensions for BP Cuff Bladders
*Calculated so that the largest arm would still allow the bladder to encircle arm by at least 80%. Source: The Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents. 2005. The National Heart, Lung and Blood Institute Informa-tion Center10. Technique
• Wrap cuff smoothly, snugly and evenly around the arm with the middle of the balloon over the brachial artery.
• Palpate radial artery and inflate cuff to 20 mmHg systolic pressure above the point when radial pulse is obliterated. • Deflate bladder 3 mmHg per second, listening with the bell of the stethoscope over the brachial artery for Korotkoff phase I (appear-ance) and phase V (disappearance)—corresponding to systolic and diastolic values respectively.
• In children, Korotkoff phase IV (distinct, abrupt muffling of sounds, becoming soft and blowing in quality) is preferred.
• The nurses and office assistants measuring blood pressure must be trained and regularly re-trained in auscultatory method of BP measurement.
• Non-mercury BP equipment should be validated every six months.
• Initial readings are taken from both arms, with the higher values used for subsequent measurements.
• Because blood pressure normally varies up to 10 mmHg, it is neces- sary to take three readings to obtain the most accurate present blood pressure. • If the first measurement exceeds 140/90 mmHg*, if practical, take a
second confirmatory reading at the end of the consultation.
• Standing BP should be recorded at the initial estimation in the
elderly and diabetic patients.
• A decrease in standing SBP >10 mmHg with associated dizziness and/or fainting is considered positive for postural hypotension and should be monitored in subsequent visits using upright position.
• In patients with symptoms or documented postural hypotension
(fall in systolic BP when standing of 20 mmHg or more) consider
referral to a specialist.
• Record the BP reading, patient position, and arm and cuff size in • All readings are recorded to the nearest 2 mmHg, not rounded to the
CLASSIFICATION AND DIAGNOSIS OF HYPERTENSION
Classification of Hypertension
130 – 139
Stage 1 hypertension (mild)
Stage 2 hypertension (moderate)
Stage 3 hypertension (severe)
**Isolated systolic hypertension 1
**Isolated systolic hypertension 2
• Pre-hypertension is not a disease category. It is a designation chosen to identify individuals at high risk of developing hypertension, so
that both patients and physicians are alerted to this risk, and are
encouraged to intervene and prevent or delay the disease from devel-
** Isolated systolic hypertension
• There is impressive evidence which has accumulated to warrant greater attention to the importance of isolated systolic hyperten-
sion as a major risk for cardiovascular diseases.
• BP changes occur with increasing age; the rise in systolic BP con- tinues throughout life in contrast to diastolic BP, which rises until approximately the age of 50, and then tends to level off over the next decade, and may remain the same or even fall thereafter.
• Diastolic hypertension predominates before age 50 either alone or in combination with systolic hypertension. The prevalence of systolic hypertension increases with age, and above age 50, it represents the most common form of hypertension.
• Before the age of 50, DBP is a more potent cardiovascular system (CVS) risk factor than SBP; thereafter, SBP is more important. Clini-
cal trials have shown that control of isolated systolic hypertension
reduces total mortality, CVS mortality, stroke, and HF events.
• Poor SBP control is largely responsible for the unacceptable low rates of overall BP control.

For those with high pressures great-er than 180/110 mmHg, evaluate and treat immediately or within one week depending on clinical situation and complications.
* Provide lifestyle modification. If systolic and diastolic categories are different, follow rec-ommendations for the shorter time follow-up (e.g., 160/86 mmHg should be evaluated or referred to source of care within one month).
** Modify the scheduling or follow-up according to reliable information about past BP mea-surements, other cardiovascular risk factors, or target organ disease.

• Is defined as consistently high BP in a medical setting (>140/90) and normal BP at home (<129/84 mmHg).
• It is more common in the elderly, accounting for more than 20% of all patients diagnosed with high blood pressure and is normally benign.
• It requires continued monitoring at home and if measurements are elevated, ambulatory blood pressure monitoring can assist with di-agnosis. Ambulatory BP Monitoring (ABPM)
• This provides detailed BP information over a 24-hour period.
• It is useful if the diagnosis of hypertension is in doubt.
• It provides more information than the office or home measurement especially showing mean daytime and night time values.
• There is an increasing body of evidence suggesting that ABPM values are better predictors of cardiovascular disease (CVD) risk, target or-gan damage, and a better method of assessing treatment effects on blood pressure. EVALUATION AND ASSESSMENT
The risk for cardiovascular disease in patients with hypertension is deter-
mined not only by the level of blood pressure, but also by the presence or
absence of target organ damage and other risk factors such as smoking,
dyslipidemia and diabetes, as shown in the Seventh Report of the Joint
National Committee on Prevention, Detection, Evaluation, and Treat-
ment of High Blood Pressure. These factors independently modify the risk
for subsequent cardiovascular disease, and their presence or absence is
determined during the routine evaluation of patients with hypertension
(i.e., history, physical examination, laboratory tests).

COMPLICATED AND RESISTANT HYPERTENSION
Complicated hypertension is defined as hypertension with end organ damage.
End Organ Damage7
• Left ventricular hypertrophy (LVH) • Angina/prior MI • Prior coronary revascularization • Heart failure • Stroke or transient ischemic attack • Dementia • Chronic kidney disease (CKD) • Peripheral arterial disease • Retinopathy The Task Group recommends: • Referral of patients with significant cardiac dysfunction to a car- • Referral to a nephrologist for patients with: • Proteinuria greater than 300 mgs/24 hr., or a • Rising Creatinine, or a • GFR less than 60 • Referral of patients with retinal haemorrhages or papilloedema, to hospital as an emergency.
Resistant hypertension is defined as failure to achieve goal blood pres-
sure in patients who are adhering to full doses of an appropriate three
drug regimen that includes a diuretic.
For resistant hypertension, the Task Group recommends first determin-ing adherence, and then if the patient is judged to be adherent, referral to a specialist for evaluation for secondary causes of hypertension (see list on page 11).
In resistant cases of hypertension, also consider other medications (in-
cluding complementary medicines) that patient may be taking that may
increase blood pressure (see table below).
Medications that can increase blood pressure
Caffeine containing products (guanara, cola, green tea) Haemopoietic agents (Epo) Immunomodulators (cyclosporine, tacroli- Oral contraceptives Oral decongestants (pseudoephedrine) Adapted from: Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. NIH, NHLBI, NHBPEP • These are defined as situations associated with severe elevations in BP without progressive target organ dysfunction.
• Conditions would include: Upper levels of Stage 2 hypertension asso- ciated with severe headache, shortness of breath, or severe anxiety. These patients present as non-adherent or inadequately treated.
• Some patients with hypertensive urgencies may benefit from treat- ment with an oral, short-acting agent such as captopril, labetolol, or clonidine followed by several hours of observation. There is no evidence to suggest that failure to aggressively lower BP in the ER is associated with any increased short-term risk to the patient who presents with severe hypertension. Such a patient may benefit from adjustment in their antihypertensive therapy, particularly the use of combination drugs.
Note that early triage to establish appropriate therapeutic strategies is critical to limit morbidity and mortality; and also most importantly, ar-range confirmed follow up visit with G.P.
Malignant hypertension is a medical emergency. Diagnosis Criteria:
• BP ≥ 180/110 mmHg PLUS ONE OR MORE of the following: • intracerebral haemorrhage• retinal haemorrhage• papilloedema• haematuria• thrombocytopenia • pulmonary edema • Malignant hypertension requires immediate blood pressure reduc- tion (not necessarily to normal) to prevent or limit organ damage.
• Admit to ICU for continuous monitoring of BP and parenteral ad- ministration of vasodilators (sodium nitroprusside, nicardipine hy-drochloride, nitroglycerin, hydraliazine, enalaprilat) or adrenergic inhibitors (labetolol, esmolol, phentolamine). The goal is to reduce mean arterial BP by no more than 25% (within minutes to one hour), then if stable, to 160/100 –110 mmHg within the next 2 – 6 hours.
• Excessive falls in pressure that may precipitate renal, cerebral, or coronary ischemia should be avoided. For this reason, short acting nifedipine is no longer considered acceptable in the initial treat-ment of hypertensive emergencies or urgencies.
• If this level of BP is well tolerated and the patient is clinically stable, further gradual reduction can be implemented in the next 24 – 48 hours. MANAGEMENT OF HYPERTENSION

• Use of appropriate cuff-size when measuring blood pressure.
• Use of combinations of medications and dosing.
• Review all medications/drugs being taken at each visit – ask specific questions, and give patients permission to tell the truth without fear of reprimand.
• Simplify drug regimens. • Recommend drug dispensing containers, or suggest location of pills to increase compliance.
• Write down a proposed schedule of all medications at each visit.
• Address adherence and the barriers to adherence at each visit.
• Encourage patient to measure home BP.
• Take time to build rapport and educate patient, thus engendering trust of the physician and the chosen mode of treatment.
• Consider out-of-office contact (i.e., phone or e-mail) especially during the first three months of therapy.
• Invite the patient to bring a family member to an early discussion about hypertension, and request their help and support of their loved one.
• Encourage cardiac care, dietitian, physiotherapist or psychologist follow-up when necessary.
• Consider use of incentives, financial or otherwise to increase motiva- LIFESTYLE MANAGEMENT

REGULAR PHYSICAL ACTIVITY
Prescribe physical activity at moderate intensity, completed in intervals
throughout the day:
• 30 – 60 minutes per day most days of the week for children.10 • ≥30 minutes per day moderate intensity for adults and for those needing to achieve weight reduction.15 • Individuals with Stage 3 Hypertension should be assessed for safety to participate in physical activity programme.15 DIETARY MODIFICATION
Referral to a registered dietitian is advised to assist patient with the rec-
ommended dietary modifications:
• Adherence to the DASH Diet/Vegetarian Diet16 – which may include fruits, vegetables, whole grains, legumes and nuts for a total of 30 – 40 gm fibre / day, lean meats, and low-fat dairy foods.
DASH Diet www.nhlbi.nih.gov/health/public/heart/hbp/dash/new_ • Reduction of sodium intake to: • 2300 mg per day for prevention of hypertension (equivalent to 1 teaspoon of salt). • 1500 mg sodium for hypertensive individuals (equivalent to 2/3 teaspoon of salt). • Strategies to reduce sodium intake include: • Following the DASH diet.
• Avoiding processed canned and fast foods.
• Avoiding adding salt during cooking and at the table.
• Reading food labels to determine sodium content of foods. A food is considered low in sodium if it contains 140 milligrams or less of sodium per serving.
• Food Label www.health.gov.bm (Appendix III).
The following are not recommended: • Supplementation of potassium, calcium and magnesium is not rec- ommended as prevention or treatment of hypertension.8 • There is insufficient evidence to recommend fish oil, supplemental fiber, high protein and low glycemic index diets as a means to lower BP.10 • Hypertensive individuals should be encouraged to reduce their weight to attain a normal BMI <25 (see Appendix IV for BMI Chart). Every 1% reduction in body weight lowers systolic BP by an average of 1 mmHg9.
• Adult BMI can be calculated at http://www.nhlbisupport.com/ • A child and adolescent BMI calculator is available at http://apps.
• Growth charts are available at http://www.cdc.gov/growthcharts • Waist circumference targets are: • <40" men • <35" women (see Appendix IV).
• Refer patient to a registered dietitian. • A multidisciplinary team approach to weight loss is encouraged. Team members should include nurse, dietitian, physiotherapist, and when necessary psychologist/behaviour therapist. The multidisci-plinary team is important in establishing weight maintenance over the long term.17 • Target weight reduction of 10% body weight should be sought through lifestyle behaviour change to: • Reduce calories by decreasing portion sizes and eliminating high calorie beverages. • Limit consumption of high fat foods. • Decrease sedentary activities. • Increase physical activity.
• Reduce age-related weight gain.
• Morbidly obese individuals (BMI >40) may benefit from drug therapy or bariatric surgery.
• Those individuals who undergo bariatric surgery require lifestyle management support post surgery.17 • For more detailed information access the The Practical Guide to the Iden- tification, Evaluation, and Treatment of Overweight and Obesity in Adults an NIH Publication and NHLBI Obesity Education Initiative from www.

The Task Group recognizes that there are a large number of drugs avail-able to reduce blood pressure. Many large-scale trials have confirmed the effectiveness of the different classes of anti-hypertensive agents, but have not confirmed superiority of any particular class. In addition, up to two-thirds of people will need two or more drugs to meet their target blood pressure.6 The British Hypertension Society in collaboration with the National In-stitute for Clinical Excellence has developed a treatment algorithm to inform the better use of logical combinations of drugs.6 These recom-mendations are largely similar to those outlined in other international guidelines, but have the benefit of a straightforward and easily interpret-ed flowchart. The Bermuda Task Group has thus recommended the adop-tion of this algorithm for our local guidelines. These guidelines apply to the ‘uncomplicated' hypertensive patient.
A drug cost comparison including more commonly prescribed anti-hyper-tensive medications available in Bermuda, has been compiled to assist in making drug choices. The Task Group believes that cost implications for the patient, and the impact on health costs for our island should be considered. This list does not include all hypertensive medications that are available. GENERAL POINTS TO CONSIDER WHEN PRESCRIBING DRUGS
• Consideration of ethnicity and age in choice of agent.6 • In hypertensive patients younger than 55, first choice initial therapy should be an angiotensin converting enzyme inhibitors (ACEI) (or an Angiotensin receptor blocker (ARBs) if an ACE inhibitor is not tolerated). • In hypertensive patients aged 55 and over, or black patients* of any age, first choice of initial therapy should be either a calcium channel blocker (CCB) or a thiazide-type diuretic.** • Hypertensive patients of South Asian descent have a higher preva- lence of insulin resistance and type 2 diabetes. These risk factors should be taken into consideration when selecting antihyperten-sives in this group.** *Black patients are those of African or Caribbean descent, and not mixed race, Asian or Chinese patients**Note that thiazides may have a variety of dose-dependent adverse meta- bolic effects, including hypokalaemia, hyperuricemia, mild elevations in the plasma cholesterol and glucose concentrations, and hyperinsulinemia.18 If there is a strong family history of diabetes or if the individual has additional risk factors for diabetes, consideration should be given to choosing an alternative first line treatment or using lowest doses to minimize metabolic abnormalities. • Beta-blockers are not recommended for first line therapy based on evidence that they perform less well than other drugs, particularly in the elderly, and the increasing evidence that suggests that the most frequently used beta-blockers at usual doses carry an increased risk of provoking type 2 diabetes.
• Drugs should be combined according to the algorithm (see Algo- rithm 2 page 26).
• Low dose initial therapy followed by addition of medications from other classes is preferable to increasing to maximum doses of indi-vidual agents. This achieves blood pressure control with a reduced side effect profile.
• Drugs should generally be titrated over four weeks.
• Long acting medications are preferable.
• Combination therapies may be of benefit for some patients but the cost implications should be considered.
• If blood pressure remains uncontrolled on maximum doses of three drugs, consider seeking specialist advice.

• Lifestyle modification is recommended to include (see Lifestyle Man- agement section page 20): • Regular exercise and increased routine physical activity. • Avoidance of tobacco.
• Moderate alcohol intake.
• Low sodium <2,300 mg or 2.3 g/day.
• All patients with diabetes should be evaluated for albuminuria at least once a year.19 DRUG THERAPY MANAGEMENT
• Most diabetics need two or more drugs for hypertension control in addition to lifestyle change.

• Start with ACEI or ARB and use combination with CCB or diuretic.
• In patients with risk factors for developing overt diabetes, choice of antihypertensive agent should take this into account. Beta-blockers and thiazide diuretics are associated with an increased risk of devel-oping new-onset type 2 diabetes compared with other agents. The relative risk of being diagnosed with diabetes is between 1.2 to 1.46 in individuals taking thiazides compared to those not taking thia-zides with similar baseline characteristics.20 • Baseline predictors of new onset diabetes during treatment with antihypertensives include increasing age, female sex, minority eth-nicity, body mass index and waist circumference, elevated fasting and post-prandial glucose, low HDL, presence of left ventricular hy-pertrophy and the degree of elevation of both diastolic and systolic blood pressures.
• Thiazide therapy rarely affects glycaemic control at low doses.5

Initial evaluation of the patient with hypertension should include assess-ment for the presence of chronic kidney disease or CKD.21 Patients with an estimated GFR <60 ml/min/1.73 m2 or preserved eGFR with presence of albuminuria (>/=200 mg/g on spot urine albumin or total protein to creatinine ratio for >3 months) are considered to have CKD.7 Progression of CKD to end-stage renal disease (ESRD) is a major public health prob-lem. Hypertension is associated with a more rapid progression to ESRD and thus, this high risk group warrants intensive hypertension manage-ment. Studies have shown that aggressive treatment of hypertension in this group of patients does slow decline in GFR. The goals of therapy in CKD are to lower blood pressure, reduce CVD risk and slow progression of CKD. Goal blood pressure for all patients with CKD is <130/80.21 • Blood pressure should be measured in all CKD patients at each visit. • Serum creatinine and estimated GFR should be measured at initial evaluation and at least yearly. The following website can be used to calculate eGFR: http://nkdep.nih.gov/professionals/gfr_calculators/ • Spot urine total protein (or albumin) to creatinine ratio. • Urine dipstick and microscopic examination.
• Blood pressure should be less than 130/80, unless compelling contrain- dication exists.
• All patients with diabetic CKD and patients with non-diabetic CKD + proteinuria (>/= 200 mg/g on spot urine total protein: creatinine ratio) should be treated with an ACE inhibitor or an ARB unless con-traindicated.21 • Monitor K and Cr carefully in patients with CKD prescribed an ACEI or ARB8. If potassium elevated (>5 mEq/L) review diet and medica-tions, e.g. NSAIDs before initiating ACEI or ARB. • Loop diuretics may enable use of ACEI/ARB. Continue ACEI / ARB if potassium level </= 5.5 meq/L.21 • Continue ACE/ARB or diuretic if GFR decline is less than 30% from baseline over four months.21 • ACEI, ARBs and renin inhibitors are contraindicated in pregnancy. and caution is required in prescribing to women of childbearing po-tential.8 • Referral to nephrologist is indicated in acute renal failure, for full
evaluation of etiology and formulation of management plan. Pa-
tients should be referred to nephrologist for ongoing care when
eGFR is <30 ml/min.
DIABETIC KIDNEY DISEASE (DM-CKD):
• Goal BP is <130/80.21 • Patients with DM-CKD, with or without hypertension, should be treated with an ACEI or an ARB21. ACE inhibitors are more effective than other antihypertensives in slowing progression of kidney dis-ease with macroalbuminuria due to DM-1.21 • Diuretics may potentiate the effects of ACEI and ARBs in diabetic NON-DIABETIC KIDNEY DISEASE (non-DM CKD):
• Multiple antihypertensive agents are usually required to reach tar- get blood pressure.21 CKD with Proteinuria
BP lowering therapy should focus on reducing proteinuria as well as treating BP to target of <130/80.19 Reducing to <125/75 may produce ad-ditional benefit in CKD with proteinuria.6 • ACEI, ARBs and nondihydropyridine CCB have a greater antiprotein- uric effect than other classes in non-DM CKD and should be used. Diuretics may potentiate the beneficial effects of ACEI and ARBs in non-DM CKD.21 • Dihydropyridine CCB should not be used in non-DM CKD with pro- teinuria in the absence of ACEI or ARB therapy.
• ACEI and ARB may be used in combination.
• If CrCl <30 ml/min. a loop diuretic should be substituted for a thia- zide diuretic, particularly if control of volume is desired.8 CKD without Proteinuria
• Goal BP remains <130/80. • Any initial agent may be used for attainment of the goal BP, although a diuretic is a good initial agent, depending on GFR. • In CKD stages 1 – 3, a thiazide, loop or K-sparing diuretic may be • In CKD stages 4 – 5, a loop diuretic is recommended.19 • Combination of ACEI and ARB is not recommended for pts with non- proteinuric CKD.8 Renovascular Disease
• Clinical clues: • Onset of hypertension <30 years old (especially if there is no fam- ily history or risk factors).
• Recent onset of hypertension after age 55.
• Abdominal bruit.
• Accelerated (malignant) or resistant (>4drugs) hypertension.
• Recurrent ‘flash' pulmonary oedema.
• CKD of uncertain etiology (especially if bland urine sediment).
• PMH of ischemic heart disease or peripheral vascular disease. • Large elevation of serum Cr, especially with marked BP reduction by ACEI or ARB (>30% increase of Cr).
• Caution with use of ACEI or ARB due to risk of AKI in bilateral dis- ease or unilateral disease with a solitary kidney. Recommend revas-cularization/stent, if uncontrolled BP or rising Cr.
Renal Transplant patients
• Target blood pressure <130/80.
• No particular class of antihypertensives superior to others. Watch K and Cr with ACEI and ARBs. A >1 mg/dL increase in serum Cr should raise the question of renal artery stenosis.
• Proteinuria after transplantation is a risk factor for graft loss and death. It is reasonable to conclude that control of proteinuria and HTN with ACEI/ARBs may have a favourable outcome on graft sur-vival and mortality.21 • Nocturnal hypertension, reversal of diurnal BP rhythm may be pres- ent so may need 24h BP to evaluate. Still relative salt and water reten-tion after renal transplant as still some renal impairment.
Autosomal dominant Polycystic Kidney Disease (ADPKD):
• Any antihypertensives may be used. No proven benefit of ACEI/ARB has been proven for reno-protection.
HYPERTENSION AND CARDIAC DISEASE
HYPERTENSION AND HEART FAILURE7
Hypertension precedes the development of heart failure in approximately 90% of patients and increases the risk for heart failure by two- to three-fold. Hypertension is especially important in heart failure affecting Afri-can-Americans and elderly persons. Systolic heart failure should generally be treated with an ACE inhibitor. In patients intolerant of ACE inhibitor, angiotensin receptor blockers (ARB) may be used. Carvedilol or metoprolol succinate are also recommended in systolic heart failure, as clinical studies have demonstrated decreased morbidity and mortality plus improvement in heart failure symptoms.
Patients with congestive heart failure (CHF) due to diastolic dysfunction and hypertension should be managed per general guidelines for hyper-tension management. Black patients with systolic heart failure who re-main hypertensive despite a trial of ACE inhibitor and beta-blocker may benefit from adding a combination of hydralazine and nitrates (mortality reduction demonstrated in the "African-American Heart Failure Trial".22 ) Loop diuretics are often necessary to control volume retention but should
be used with care. There is no evidence that diuretics prevent progression
of disease, and diuretics can also increase serum creatinine levels when
used in excess. Aldosterone antagonists may provide additional benefit in
patients with severe left ventricular dysfunction, usually New York Heart
Association class 3 – 4. Studies generally demonstrate reduced mortality
by using Aldosterone antagonist in this situation. Hyperkalemia is a risk
with Aldosterone antagonist, and therefore these agents should be used
only in patients with serum creatinine less than 2.5 mg/dl, with serum
potassium monitored closely in all patients.
Blood pressure targets in heart failure have not been firmly established. Systolic blood pressures are generally lowered to the range 110 – 130. Very low blood pressures (systolic blood pressures less than 100) may be desir-able in some heart failure patients, to maximize after load reduction, as long as lower blood pressures are tolerated from a symptom standpoint. HYPERTENSION AND ISCHEMIC HEART DISEASE7
Hypertensive patients are at increased risk for myocardial infarction or other major coronary events and may be at higher risk for death follow-ing acute myocardial infarction. Lowering both systolic and diastolic blood pressures reduces ischemia in part by reducing myocardial oxygen demand. However, some studies have shown an apparent increase in coro-nary risk at low levels of diastolic blood pressure, generally in the range of 60 ml of mercury or less. Therefore, patients with occlusive coronary disease and or left ventricular hypertrophy should maintain a diastolic blood pressure above 60 mmHg. Systolic blood pressure should be treated to a target of less than 130 mmHg.
Unless contraindicated, pharmacologic therapy should be initiated with a beta-blocker. Beta-blockers will lower blood pressure, reduce symptoms of angina, improve mortality, and reduce myocardial oxygen demand. If blood pressure or anginal symptoms are not controlled by beta-blocker therapy alone, or beta-blockers are not tolerated, as in the presence of reactive airway disease, severe peripheral arterial disease, or high degree AV block, either long-acting dihydropyridine (amlodipine, nifedipine SR, felodipine SR) or non-dihydropyridine type calcium channel blockers (diltiazem and verapamil) may be used. Diltiazem or verapamil, in com-bination with a beta-blocker, can cause bradycardia or high degree AV block. Therefore, amlodipine, nifedipine SR, felodipine SR are preferred for combination therapy with beta-blockers. Nitrates may be added as a third agent.
Short-acting nifedipine should not be used because of demonstrated po-tential to increase mortality, particularly in the setting of an acute myo-cardial infarction.
HYPERTENSION AND SURGERY
Uncontrolled hypertension is associated with wider fluctuations of BP during induction of anesthesia and intubation, and may increase the risk for peri-operative ischemic events. The Task Group recommends that: • Sustained hypertension should be controlled prior to elective opera- tive procedures.
• Surgical candidates with controlled hypertension should be main- tained on their medications up until the time of surgery.
• Antihypertensive medication should be reinstated as soon as pos- • Hypokalaemia should be corrected in advance of surgery.
• For older patients, consideration should be given to treatment with beta-1 selective beta-blockers before and during the peri-operative period.
Hypertension is very common in the early post-operative period and may be related to increased sympathetic tone and vascular resistance. The Task Group recommends that in the post-operative setting: • Consideration is given to factors such as pain and increased intravas- cular volume.
• If resumption of oral treatment must be interrupted, periodic dos- ing with intravenous enalapril or transdermal clonidine hydrochlo-ride may be useful.
HYPERTENSION AND STROKE
Increased blood pressure is the most significant and treatable risk factor
for primary stroke and recurrence of stroke even in the very elderly. All
five major classes of antihypertensive agents are effective in preventing
first ever stroke and can be considered, depending on cost, adverse effect
profiles and co morbidities.6,7,9
There is well established evidence that BP-lowering therapy is effective
in preventing recurrent stroke and other major vascular events in people
with an established history of stroke or TIA.
Even those with BP initially less than 140/90 mmHg benefit from antihy-pertensive therapy. The benefits appear to be greater in those with a his-tory of intracerebral haemorrhage than in other stroke subtypes.
Antihypertensive therapy should be initiated with caution in the very old or frail, in patients with severe carotid stenosis, and in those with initial BP levels less than 120 mmHg systolic. 6,7,8, 9 The most direct available evidence for effective secondary prevention of stroke comes from studies using diuretics or combination of ACE inhibi-tors and diuretics.6,7,8, 9 Acute Stroke
Following acute stroke, BP is often raised and falls spontaneously over the
next few days. Both high and low blood pressure levels immediately post
stroke are associated with an adverse prognosis.
The American Stroke Association has issued guidelines suggesting that in patients with recent ischemic stroke with systolic >220 or diastolic 120 – 140, cautious reduction of BP by 10 – 15% is suggested.
In situations where thrombolytic agents are to be used, BP needs to be controlled. Systolic BPs >185 or diastolic >110 contraindicate the use of tPA.
The KEMH utilizes the stroke guidelines of the Massachusetts General Hospital (MGH) to treat BP for ischemic stroke and hemorrhagic stroke. Note that the guidelines below for ischemic stroke do not pertain to pa-tients eligible for or undergoing tPA treatment.
MGH ischemic stroke BP management guidelines:
• Systolic less than or ≤ 220 OR diastolic less than or ≤ 120 • Observe unless other end-organ involvement (e.g., aortic dissec- tion, acute myocardial infarction, pulmonary edema, hyperten-sive encephalopathy).' • Treat other symptoms of stroke (e.g., headache, pain, agitation, nausea, vomiting). • Treat other acute complications of stroke, including hypoxia, in- creased intracranial pressure, seizures, or hypoglycemia. • Systolic >220 OR diastolic 121 – 140. Two options: • Labetalol 10 – 20 mg IV for 1 – 2 min. • May repeat or double every 10 min. (max. dose 300 mg) • Nicardipine 5 mg/h IV infusion as initial dose; titrate to de- sired effect by increasing 2.5 mg/h every 5 min. to max. of 15 mg/h. • Aim for a 10% – 15% reduction in blood pressure. • Diastolic >140: • Nitroprusside 0.5 mcg/kg/min. IV infusion as initial dose with continuous blood pressure monitoring. • Aim for a 10% – 15% reduction in blood pressure. MGH hemorrhagic stroke guidelines
• Blood pressure should be managed according to American Heart Association 2007 Guidelines for the Management of Intracerebral Hemor-rhage. All patients who require treatment with continuous intrave-nous antihypertensive therapy should undergo urgent placement of an intra-arterial catheter for blood pressure monitoring and central venous catheter for central venous pressure monitoring as well as administration of IV antihypertensive medications. Once a physician determines that a patient requires treatment with IV antihyperten-sive therapy, he/she must designate an individual who will remain at the bedside and monitor effectiveness of therapy until blood pres-sure is controlled. • Elevated blood pressure (suggested medications in approximate or- der of preference): • Labetalol: 5 – 100 mg/hr. by intermittent bolus doses of 10 – 40 mg or continuous drip (2 – 8 mg/min.) • Nicardipine: 5 mg/hr. increased by 2.5 mg/hr. q15 minutes to max. • Esmolol: 250 mcg/kg as a load; maintenance use, 25 – 300 mcg/kg/ • Enalapril: 0.625 – 5 mg IV Q6h. • Hydralazine: 5 – 20 mg IV Q30 min. • Nitroprusside: 0.1 – 10 mcg/kg/min. • The following suggested algorithm is adapted from the AHA 2007 Guidelines for ICH: • If SBP is >200 mmHg or MAP is greater than 150 mmHg, then consider aggressive reduction of blood pressure with continuous intravenous infusion, with frequent blood pressure monitoring every five minutes. • If SBP is >180 mmHg or MAP is greater than 130 mmHg and there is evidence of or suspicion of elevated ICP, then consider moni-toring ICP and reducing blood pressure using intermittent or continuous intravenous medications to keep cerebral perfusion pressure greater than 60 to 80 mmHg. • If SBP is >180 mmHg or MAP is greater than 130 mmHg and there is not evidence of or suspicion of elevated ICP, then consider a modest reduction of blood pressure (e.g., MAP of 110 mmHg or target blood pressure of 160/90 mmHg) using intermittent or con-tinuous intravenous medications to control blood pressure. • Any clinical deterioration in association with reduction of BP should prompt reconsideration of ongoing BP management strategy. • The etiology of hypotension must be established. Volume replen- ishment is the first approach. Isotonic saline or colloids can be used and monitored with central venous pressure. If CVP is nor-mal or elevated in the setting of hypotension, then a pulmonary artery catheter should be placed to monitor pulmonary artery pressures. If hypotension persists after correction of volume defi-cit, continuous infusions of vasopressors should be considered, particularly for low systolic blood pressure such as less than 90 mmHg. • Phenylephrine: 2 – 10 mcg/kg/min. • Dopamine: 2 – 20 mcg/kg/min. • Norepinephrine: 0.05 – 0.2 mcg/kg/min. Treating hypertensive women leads to a greater reduction in CVD as com-pared to men. A recently published study indicates that lowering systolic pressure by 15 mmHg in hypertensive women, reduced CVD by 40 per cent in women compared to 20 per cent in men.23 There are additional factors to consider with regard to blood pressure in certain groups of women.
Oral Contraceptives6, 7
• Monitor BP prior to usage then six monthly as combined oral contra- ceptives can raise BP levels.
• If already hypertensive, use POP (Progesterone Only Pill).
• Women over 35 years with other coexistent risk factors, e.g. smoking and migraine should not use the combined oral contraceptive.
• For women with stage 1 hypertension who wish to continue oral contraception, monitor BP, recommend salt restriction, and use an-tihypertensives. Combined oral contraceptives are contraindicated in women with Stage 2 hypertension.
Women on Hormone Replacement Therapy (HRT)6,7
• HRT does not cause BP to rise so women with hypertension should not be denied access.
The following conditions do not necessarily follow a specific order. For ex-
ample a pregnant woman can have pre-eclampsia and end up with HEELP
or have pre-eclampsia and end up with eclampsia. Additionally, HELLP
can occur after delivery.
• Chronic hypertension is defined as BP >140/90 before the 20th week
of pregnancy, or if only measured after 20 weeks gestation, persist-ing six weeks post-partum.
• Gestational hypertension is defined as the development of hyper-
tension in pregnancy without other signs of pre-eclampsia.
• Pre-eclampsia is usually diagnosed on the basis of hypertension
with proteinuria. Proteinuria is defined as 300 mg/l protein, or 30 mg/mmol creatinine in a random specimen, or an excretion of 300 mg per 24 hr. Hypertension is defined as SBP >140 mmHg or DBP >90 mmHg after 20 weeks in a pregnant woman who was normotensive before 20 weeks gestation.
• Pre-eclampsia superimposed on chronic hypertension is regarded
as highly likely in women with known hypertension who develop new proteinuria or in women with known hypertension and protein-uria who have sudden increases in BP or proteinuria, thrombocyto-penia, or increases in hepatocellular enzymes.
• HELLP Syndrome (hemolysis, elevated liver enzymes, low platelet
count). Symptoms are headache, nausea and vomiting that gets con-tinuously worse, upper abdominal pain and vision problems.
• Eclampsia is often preceded by premonitory signs including head-
ache, visual disturbances, and epigastric pain, constricting sensa-tions in the thorax, apprehension, excitability, and hyperflexia. However, convulsions can occur suddenly and without warning in a seemingly stable patient with no apparent or only minimal eleva-tions of BP.
Pregnant women with pre-eclampsia and hypertension should
have their urine checked for protein in addition to vital signs per-
formed at their visits. These patients should be monitored closely
with the advice of an obstetrician.
The following drugs are commonly used to treat hypertension in preg-
• Methyldopa first choice. • CCB's (nifedipine/labetolol) are second choice in resistant hyperten- sion especially in third trimester.
• Beta-blockers are not used because of the risk of intrauterine growth • Thiazides are avoided due to potential to reduce circulatory blood • ACEI are avoided and discontinued in women who are planning • Magnesium sulphate for pre-eclampsia/eclampsia.
• Low-dose aspirin for prevention is controversial. • Erectile dysfunction (ED) is increasingly more common in men over 50 and even more common if those who are hypertensive. • Screen for ED annually or more frequently as required (Appendix V) • A lower risk of ED was reported among men who were physically active, not obese, and non-smokers. Therefore, lifestyle modification should be encouraged to prevent ED. • If ED appears after institution of antihypertensive drug therapy, the offending agent should be discontinued and treatment restarted with another agent.7 • There is broad agreement that postural hypertension is far more prevalent in this population. To this end the following recommen-dations:• Lying, sitting and standing BP measurements are to be taken.
• Treatment should be titrated to the standing value.
• Restrict alcohol use.
• Isolated Systolic Hypertension is more prevalent in the elderly and should be treated to reduce risk of stroke.
• SBP should be the target for diagnosis and management of HTN in the elderly.
• Comorbidities are common; therefore poly-pharmacy is an impor- tant factor to consider. Watch for: • Adverse drug reactions.
• Drug interactions (e.g., NSAIDS).
CHILDREN AND ADOLESCENTS
In children and adolescents BP is determined by body size and age. BP standards based on gender, age, and height provide a precise classifica-tion of BP according to body size. This approach avoids misclassifying chil-dren who are very tall or very short. The information in this section is taken largely from The Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents.10 DEFINITION
Hypertension is defined as average SBP and/or diastolic BP (DBP) that is
≥95th percentile for gender, age, and height on ≥3 occasions.10
Blood Pressure Category
<90th percentile 90th – 95th percentile or >120/80 mmHg 95th – 99th percentile + 5 mmHg > 99th percentile + 5 mmHg White-coat hypertension95% at physician office and normotensive outside clini-cal setting MEASUREMENT OF BP IN CHILDREN
All children >3 years old who are seen in a medical setting should have
their BP measured.10
• The preferred method is auscultation. • Appropriate cuff size – the width of cuff bladder should be ¾ of the length of upper arm. If high blood pressure obtained always verify the width of the cuff in relation to the length of upper arm by direct measurement. Also see the referred table. • Use standard clinical sphygmomanometer, with bell of stethoscope placed over the brachial artery pulse, proximal and medial to the antecubital fossa, below the bottom edge of the cuff . • Child should be in comfortable, relaxed position, and seated with his or her back supported, feet on the floor and right arm supported, and at the level of heart. • Fifth Korotkoff sound defines diastolic BP.
• The right arm is preferred because of the possibility of coarctation of Conditions under Which Children <3 Years Old Should Have BP Measured10
• History of prematurity, very low birth weight, or other neonatal complication requiring intensive care.
• Hypertension of placement of any indwelling umbilical catheters.
• Congenital heart disease (repaired or non-repaired).
• Recurrent urinary tract infections, haematuria, or proteinuria.
• Renal disease or urologic malformations.
• Solid-organ transplant.
• Malignancy or bone marrow transplant.
• Treatment with drugs known to raise BP.
• Other systemic illnesses associated with hypertension (neurofibro- matosis, tuberous sclerosis, etc).
• Evidence of elevated intracranial pressure.

To accurately assess blood pressures in boys and girls it is recommended
to use Tables 3 and 4 from the Fourth Report on the Diagnosis, Evaluation,
and Treatment of High Blood Pressure in Children and Adolescents (2005). These
tables enable assessment of blood pressure levels by age and height per-
centile for boy and girls. The tables can be found in Appendices VI and VII
(pages 62 – 65).
Using the BP Tables10
1. Use the standard height charts to determine the height percen- 2. Measure and record the child's SBP and DBP. 3. Use the correct gender table for SBP and DBP. 4. Find the child's age on the left side of the table. Follow the age row horizontally across the table to the intersection of the line for the height percentile (vertical column). 5. There, find the 50th, 90th, 95th, and 99th percentiles for SBP in the left columns and for DBP in the right columns. Classification of Hypertension in Children and Adolescents, with Measurement

• The Cardiac Care Programme, KEMH is a nurse-managed programme to assist patients in managing their heart disease at home. It is also a programme to help address risk factors associated with heart disease. Patients who have undergone angioplasty, or bypass, or have had a heart attack should be referred by their physician. Patients with no known heart disease but have risk factors for heart disease will also be accommodated. The Cardiac Care Programme work very closely with the Day Hospitals' Cardiac Exercise Programme to provide a complete Cardiac Rehabilitation Service.

DASH diet: Guide to recommended servings
The Dietary Approaches to Stop Hypertension (DASH) diet can help you control your blood pressure. The DASH diet is rich in grains, fruits, veg-etables and low-fat dairy products. It limits fat, saturated fat and choles-terol and provides plenty of fibre, potassium, calcium and magnesium. The DASH diet also limits sodium to between 2,300 milligrams and 1,500 milligrams a day. Here are the types and amounts of foods recommended in the DASH diet, along with specific examples of serving sizes. Use these details as you plan your own menus. Servings for a

For research purposes, the standard deviations in Appendix Table B–1 allow one to compute BP Z-scores and percentiles for girls with height percentiles given in Table 4 (i.e., the 5th,10th, 25th, 50th, 75th, 90th, and 95th percentiles). These height percentiles must be converted to height Z-scores given by (5% = -1.645; 10% = -1.28; 25% = -0.68; 50% = 0; 75% = 0.68; 90% = 1.28%; 95% = 1.645) and then computed according to the methodology in steps 2–4 described in Appendix B. For children with height percentiles other than these, follow steps 1–4 as described in Appendix B. 1Department of Health. Health Priorities Report.
