Left ventricular hypertrophy and antihypertensive therapy.
Left ventricular hypertrophy is more common in hypertensive individuals than in normotensive persons. Its presence in hypertensive patients is associated with an increased incidence of ventricular arrhythmias, myocardial infarction, congestive heart failure, stroke and cardiovascular mortality. Echocardiography is more sensitive than electrocardiography in detecting left ventricular hypertrophy. Echocardiographic evidence of this condition in patients with borderline hypertension may identify those who need treatment. Weight reduction and drug therapy can prevent or reverse ventricular hypertrophy in hypertensive patients. Recent studies suggest that some antihypertensive drugs are more effective than others in reducing left ventricular hypertrophy. These agents include beta-adrenergic blockers, angiotensin converting enzyme inhibitors, calcium channel blockers and sympatholytic agents. Although little evidence exists to show that reduction of left ventricular mass decreases cardiovascular morbidity and mortality, avoidance of antihypertensive agents that may aggravate hypertrophy would seem prudent.
