  • Title: [Regression of left ventricular hypertrophy in hypertensive patients under long-term therapy with antihypertensive agents].
    Author: Franz IW, Tönnesmann U, Behr U, Ketelhut R.
    Journal: Dtsch Med Wochenschr; 1990 Apr 20; 115(16):603-9. PubMed ID: 2139409.
    Abstract:
    The effect of long-term therapy of hypertension with antihypertensive drugs was investigated in 117 previously untreated patients (15 women, 102 men; mean age 46.4 +/- 9 years) with echocardiographically proven left-ventricular hypertrophy. 22 patients (group 1) received 100 mg/d Gallopamil, 25 (group 2) received 200 mg/d Metoprolol, 35 daily received both 50 mg Atenolol and 20 mg Nifedipine (group 3), 14 received daily 200 mg Acebutolol plus 20 mg Nifedipine (group 4), and 21 (group 5) 50 mg Atenolol plus 10 mg Enalapril daily. The treatment period lasted a mean of 38 (36.2-42.3) months. Left-ventricular muscle mass index (LVMI) as well as septal and posterior-wall thickness decreased significantly after 12.8 and 38.5 months (P less than 0.001). After a mean of 38.5 months LVMI had decreased by 36.7% in group 1, 35.1% in group 2, 42.3% in group 3, 45% in group 4 and 39.6% in group 5. LVMI was within normal range (less than or equal to 95 g/m2) in 81 of the 117 patients (69.2%) at the end of the treatment period. There was, however, no significant increase of the end-diastolic dimension of the left ventricle, but a significant increase of "fractional shortening" as a measure of myocardial contractility.
