Abstract

Abnormal left ventricular diastolic performance, an early manifestation of hypertension in the heart, may precede the development of left ventricular hypertrophy. To assess effects of antihypertensive therapy on the heart, left ventricular mass (determined by echocardiography) and rapid left ventricular filling rate (determined by radionuclide ventriculography) were compared before and after 6 months of treatment of 16 patients. Nitrendipine (a dihydropyridine calcium channel blocker) was given alone or in combination with either propranolol or hydrochlorothiazide, or both, and significantly reduced blood pressure (156/103 ± 12/7 to 137/89 ± 10/6 mm Hg). In 6 of the 16 patients, left ventricular mass decreased by more than 10% (270 ± 95 to 193 ± 47 g, p < 0.01); in the same patients, left ventricular filling rate increased (2.03 ± 0.35 to 2.30 ± 0.45 end-diastolic counts/s [EDC/s], p < 0.01). In the one patient whose left ventricular mass increased (137 to 195 g), left ventricular filling rate decreased from 2.01 to 1.78 EDC/s. In the remaining nine patients who had no change in left ventricular mass, there was no significant change in left ventricular filling. The changes in ventricular mass and filling could not be related to the extent of change in blood pressure or heart rate. These data suggest that regression of left ventricular mass during antihypertensive therapy with nitrendipine is accompanied by improved diastolic function. © 1986, American College of Cardiology Foundation.
