Abstract

Background: Hypertension is a major independent risk factor for cardiac deaths, and diastolic dysfunction is a usual finding during the course of this disease. Hypothesis: This study was designed to investigate the effects of chronic therapy with perindopril on left ventricular (LV) mass, left atrial size, diastolic function, and plasma level of atrial natriuretic peptide (ANP) in patients with hypertension. Methods: Twenty four patients who had not been previously taking any antihypertensive medication and without prior history of angina pectoris, myocardial infarction, congestive heart failure, dysrhythmias, valvular heart disease, or systemic illnesses received 4-8 mg/day of perindopril orally. Echocardiographic studies were acquired at baseline and 6 months after the initiation of therapy. Results: Systolic and diastolic blood pressure decreased from 174 ± 19.7 and 107.5 ± 7.8 mmHg to 134 ± 10.6 and 82 ± 6.7 mmHg, respectively (p <0.001). Left ventricular mass decreased from 252.4 ± 8.3 to 205.7 ± 7.08 g and left atrial volume from 20.4 ± 5.1 to 17.6 ± 5.2 ml, respectively (p <0.001). Transmittal Doppler early and atrial filling velocity ratio (E/A) increased from 0.69 ± 0.06 to 0.92 ± 0.05 m/s and plasma ANP level decreased from 71.9 ± 11.7 to 35.3 ± 7.8 pg/ml (p <0.001). Reduction of LV mass correlated positively with a reduction in ANP levels (r = 0.66, p <0.0005). Conclusions: Perindopril caused a significant reduction of LV mass, left atrial volume, and plasma ANP levels, as well as improvement in Doppler parameters of LV filling in this group of patients with hypertension.
