Abstract
AIMS: The effects of statin therapy in patients with chronic kidney disease (CKD) remain uncertain. We undertook a systematic review and meta-analysis to investigate the effects of statin on major clinical outcomes.
METHODS AND RESULTS: We systematically searched MEDLINE, Embase, and the Cochrane Library for trials published between 1970 and November 2011. We included prospective, randomized, controlled trials assessing the effects of statins on cardiovascular outcomes in people with kidney disease. Summary estimates of relative risk (RR) reductions were calculated with a random effects model. Thirty-one trials that include at least one event were identified, providing data for 48 429 patients with CKD, including 6690 major cardiovascular events and 6653 deaths. Statin therapy produced a 23% RR reduction (16-30) for major cardiovascular events (P<0.001), an 18% RR reduction (8-27) for coronary events, and 9% (1-16) reduction in cardiovascular or all-cause deaths, but had no significantly effect on stroke (21%, -12 to 44) or no clear effect on kidney failure events (5%, -1 to 10). Adverse events were not significantly increased by statins, including hepatic (RR 1.13, 95% CI 0.92-1.39) or muscular disorders (RR 1.02, 95% CI 0.95-1.09). Subgroup analysis demonstrated the relative effects of statin therapy in CKD were significantly reduced in people with advanced CKD (P < 0.001) but that the absolute risk reductions were comparable.
CONCLUSION: Statin therapy reduces the risk of major cardiovascular events in patients with chronic kidney disease including those receiving dialysis.
