Left ventricular hypertrophy (LVH) is frequently found at the initiation of dialysis therapy of diabetic and hypertensive patients, and is highly predictive of future cardiac morbidity and mortality. In patients with hypertension and LVH, both an angiotensin converting enzyme (ACE) inhibitor and an angiotensin type 1 receptor (AT1) antagonist regress LVH. However, it remains controversial whether dual blockade of the renin-angiotensin system will regress LVH in these patients using a combination of ACE inhibitor and AT1 antagonist. Thirty-three type II diabetic patients with end-stage renal disease who had just entered into hemodialysis therapy and were diagnosed as having LVH evaluated by echocardiography were selected from three dialysis units staffed by the faculty of Saitama Medical School, Saitama, Japan between 1999 and 2001. The study was carried out for 1 year. All patients were assigned randomly to three groups with equal number: group I, an ACE inhibitor, enalapril 10 mg daily; group II, an AT1 antagonist, losartan 100 mg daily; group III, combination of enalapril 10 mg and losartan 100 mg daily. All antihypertensive drugs were given 30 min after the cessation of dialysis therapy. LVH was evaluated by echocardiography before the start of administration of drugs, at 6 months and 12 months after the start of drug therapy. Systolic blood pressure levels less than 140 mmHg were the target for the three groups. Using repeated measures analysis of variance, applied to those with four echocardiograms, there were progressive decreases over time in left ventricular mass index, posterior wall thickness and interventricular septum thickness. There were no significant differences in regression of LVH as well as blood pressure control between enalapril and losartan groups; however, dual blockade induced an additional 28% reduction in left ventricular mass index compared with any type of monotherapy. Both ACE inhibitors and AT1 antagonists benefit the regression of LVH in diabetic patients who start dialysis therapy. Moreover, combination therapy with ACE inhibitors and AT1 antagonists would provide more beneficial effects on LVH in these patients than monotherapy.
