摘要

Introduction: Left ventricular hypertrophy (LVH) is a major cardiovascular complication and an important predictor of mortality in patients with end-stage renal disease. Angiotensin II blockades have been widely used in the treatment of hypertension; however, the influence of angiotensin receptor blockers (ARBs) on LVH in dialysis patients has not been thoroughly studied. In this meta-analysis, the authors analyzed the effect of ARBs on LVH and left ventricular function in patients on maintenance dialysis. Methods: The authors did systematic search of PubMed, Embase and Cochrane Central Register of Controlled Trials, until November 2010. Data extracted from the literature were analyzed with the Review Manager. Results: The results of 6 randomized controlled trials (207 participants) reveal that ARB group had a greater regression of left ventricular mass index (LVMi) when compared with non-ARB group (P = 0.002) in dialysis patients while no significant difference for left ventricular ejection fraction (LVEF; P = 0.30). The ARB group had a nonsignificantly greater therapeutic value of LVMi or LVEF when compared with angiotensin-converting enzyme inhibitor (ACEI; P = 0.74 and 0.49, respectively). No significant alterations were observed in LVMi and LVEF between the combination of ARBs and ACEIs and ARBs group (P = 0.43 and 0.24, respectively). Conclusions: ARBs are associated with a greater reduction in LVH in patients on dialysis. The ARB therapy tends to have a similar favorable effectiveness as ACEI; however, the combination of ARBs with ACEIs did not show additional benefit to LVH in patients on hemodialysis.
