title: [Reversal of left ventricular hypertrophy after the use of benazepril].
abstract: OBJECTIVE
  To assess the effects of benazepril (ACE inhibitor) on arterial blood pressure (ABP) and left ventricular mass index (LVMI).
  
  
  METHODS
  Nineteen patients (7 men, 12 women) with mean age 38.2 +/- 10.2 years, with mild to moderate hypertension were evaluated. Besides raised blood pressure, the necessary inclusion criterion was the presence of left ventricular hypertrophy detected by echocardiogram. After a wash-out period, all patients were given placebo followed by the active drug benazepril at a dose of 10 mg once a day. For those patients who did not achieve a satisfactory control of the blood pressure (BP) 25 mg of chlorthalidone was added. All patients underwent 180 days of benazepril treatment.
  
  
  RESULTS
  The ABP was gradually controlled as follow: at seated position the systolic BP changed from 156.05 +/- 5.07 mmHg to 129 +/- 3.74 mmHg (p < 0.001) and the diastolic BP from 99.74 +/- 1.59 mmHg to 81.8 +/- 2.27 mmHg (p < 0.001). At orthostatic position the systolic BP changed from 156.9 +/- 5.35 mmHg to 124.28 +/- 5.33 mmHg (p < 0.001) and the diastolic BP from 101.7 +/- 1.34 to 81.36 +/- 2.81 (p < 0.001). The heart rate did not change significantly during the study. The LVMI decreased significantly from 182.4 +/- 9.2g/m2 to 122.6 +/- 4.2g/m2 (p < 0.001).
  
  
  CONCLUSIONS
  Our data revealed that 100% of the patients achieved satisfactory degrees of LVMI regression and in 34% there was a normalization of it.
