title: ACE inhibitors captopril and enalapril induce regression of left ventricular hypertrophy in hypertensive patients with chronic renal failure.
abstract: BACKGROUND
  Left ventricular hypertrophy is frequently noted in patients with moderate to severe chronic renal failure not requiring dialysis. Recently, several studies have shown reversal of myocardial hypertrophy in end-stage renal disease with long-term pharmacological control of blood pressure, but it is unclear whether left ventricular mass regresses or normalizes with antihypertensive treatment of patients with earlier stages of chronic renal failure.
  
  
  METHODS
  Seventy-two undialysed patients with chronic renal failure, chronic mild-to-moderate hypertension, and left ventricular hypertrophy were randomly assigned in a prospective study to either the captopril (n = 36) or enalapril group (n = 36). Blood pressure measurements, echocardiographic and Doppler parameters were evaluated before treatment and at 6 and 12 months of therapy.
  
  
  RESULTS
  During follow-up, six patients developed side-effects including dry cough, taste disturbances, skin rash and gastric intolerance. In the captopril group there was a decrease in mean left ventricular mass index by 12% after 6 months of treatment, which decreased by 20% after 12 months treatment. For enalapril, the average reduction of myocardial mass after 6 months treatment was 14% and after 12 months treatment, the decrease was 19%. In both treatment groups there was significant improvement of left ventricular filling dynamics. No deterioration of left ventricular systolic function was observed.
  
  
  CONCLUSIONS
  Our results confirm that antihypertensive monotherapy with the ACE inhibitors, captopril and enalapril, in patients with chronic renal failure results in regression of left ventricular mass index associated with a significant improvement in the diastolic function of the left ventricle without a demonstrable deterioration in left ventricular systolic performance.
