title: [Regression of left-ventricular myocardial hypertrophy in patients with hypertension during long-term treatment with beta-adrenergic blockaders].
abstract: Thirty-nine patients with second-stage essential hypertension were treated with Beta-adrenoblockers of different classes for 2.5 to 3 years. Two groups of patients were distinguished: 23 patients showing a regression of left-ventricular myocardial weight (group 1) and 16 patients without such developments (group 2). A significant decrease in arterial blood pressure (by 20-24%) and heart rate (by 15 to 18%) was recorded in both groups. Total peripheral resistance was changed insignificantly in group 1 and by 9.7% (p less than 0.05) in group 2. The end diastolic volume decreased by 5.4% (p less than 0.05) in group 1, and increased by 4.7% (p less than 0.05) in group 2. The end systolic volume decreased by 10.6% (p less than 0.05) in group 1 and increased by 5% (p greater than 0.1) in group 2. Myocardial contractility declined significantly in both groups (by 9.5% and 10.6%, respectively). Intramyocardial tension dropped by 13-20% (p less than 0.001) in both groups. Therefore, the regression of left-ventricular myocardial hypertrophy was shown to have a favorable effect on cardiac function.
