Abstract

Thiazide diuretics, ß-blockers, calcium channel blockers, and angiotensin converting enzyme (ACE) inhibitors are all superior to placebo for the primary prevention of coronary events in patients with hypertension. Recent studies have shown that ACE inhibitors are better than other antihypertensive agents in lowering overall cardiovascular morbidity and mortality, especially stroke. Blood pressure should be aggressively lowered (to < 140/90 mm Hg), especially in diabetic patients (to < 130/80 mm Hg), but care should be exercised in lowering the diastolic blood pressure below 65 mm Hg in patients with significant occlusive coronary artery disease. Hypertension in patients with stable angina should be treated with a ß -blocker (alternatively a calcium channel blocker) together with an ACE inhibitor. Patients with hypertension and acute coronary syndrome (unstable angina or myocardial infarction) should be treated with a ß-blocker, and with an ACE inhibitor if there is left ventricular dysfunction. A thiazide diuretic and/or a dihydropyridine calcium channel blocker could be added for blood pressure control. Calcium channel blockers should be avoided if there is significant left ventricular dysfunction.
