title: Reduction of left ventricular mass by lisinopril and nifedipine in hypertensive renal transplant recipients: a prospective randomized double-blind study.
abstract: BACKGROUND
  Cardiovascular disease is the dominant cause of death in renal transplant recipients. Left ventricular hypertrophy (LVH) is a known risk factor. After renal transplantation, persistent hypertension is an important determinant for the further evolution of LVH. The aim of the present study was to compare the effect of an angiotensin converting enzyme (ACE) inhibitor (lisinopril) with a calcium channel blocker (CCB) (controlled release nifedipine) in treatment of posttransplant hypertension focusing on changes in LVH.
  
  
  METHODS
  One hundred fifty-four renal transplant recipients presenting with hypertension (diastolic BP> or =95 mmHg) during the first 3 weeks after transplantation were randomized to receive double-blind 30 mg nifedipine or 10 mg lisinopril once daily.
  
  
  RESULTS
  One hundred twenty-three patients completed 1 year of treatment. Good quality echocardiographic data were available in 116 recipients (62 nifedipine/54 lisinopril) 2 and 12 months posttransplant. Blood pressure was equally well controlled in the two groups throughout the study (mean systolic/diastolic+/-SD after 1 year: 140+/-16/87+/-8 mmHg with nifedipine and 136+/-17/85+/-8 mmHg with lisinopril). Left ventricular mass index was reduced by 15% (P<0.001) in both groups (from 153+/-43 to 131+/-38 g/m2 with nifedipine and from 142+/-35 to 121+/-34 g/m2 with lisinopril). There were no statistically significant differences between the two treatment groups at baseline or at follow-up.
  
  
  CONCLUSIONS
  In hypertensive renal transplant recipients with well-controlled blood pressure, there is a regression of left ventricular mass after renal transplantation. The regression of left ventricular mass index is observed to a similar extent in patients treated with lisinopril or nifedipine.
