Treatment of hypertensive patients with coexisting coronary arterial disease

Despite clear guidelines and an array of available antihypertensive medications, patients with hypertension and coronary artery disease are often inadequately treated. New data from HOPE, LIFE, and ALLHAT underscores the importance of blood pressure reduction for patients with coronary artery disease. Despite our improved understanding of the mechanism by which the various classes of antihypertensive medications achieve their effect, it remains the case that blood pressure reduction remains more important than the medication used to achieve the reduction. For most patients with coronary artery disease, combination therapy will be required to achieve a target blood pressure of less than 140/80. When tolerated, this therapy should include a beta-blocker and ACE inhibitor, both of which are of prognostic benefit for patients with coronary artery disease. There are also attractions in choosing calcium antagonists because of their efficacy in controlling anginal symptoms (Dihydropyridine calcium channel blockers if already on a beta-blocking agent and rate-limiting calcium channel blockers if beta blockers are contraindicated). Thiazide diuretics have proven themselves effective again in the ALLHAT study and are likely to be an integral part of treatment for the great majority of patients with coronary artery disease.
