Aim: We carried out an update of a Cochrane review evaluating the effects of antiplatelet treatment for the prevention of cardiovascular and adverse kidney outcomes in individuals with CKD.

Background: Antiplatelet agents are widely used to prevent cardiovascular events. The risks and benefits of antiplatelet treatment may be different in people with chronic kidney disease (CKD) for whom occlusive atherosclerotic events are less prevalent, and bleeding hazards might be increased.

Methods: We selected randomised controlled trials of any antiplatelet treatment versus placebo or no treatment, or direct head-to-head antiplatelet agent studies in people with CKD. Treatment effects were estimated by random-effects meta-analysis. Evidence certainty was adjudicated using GRADE methodology.

Results: 110 studies (52424 participants) were included. Risk of bias was generally high or unclear. Antiplatelet agents probably reduce the risk of myocardial infarction (RR 0.87, 95% CI 0.76 to 0.99; moderate certainty evidence) and increase major bleeding (RR 1.35, 95% CI 1.10 to 1.65; moderate certainty evidence), and may increase the risk of minor bleeding in CKD and haemodialysis patients (RR 1.55, 95% CI 1.27 to 1.90; low certainty evidence). Limited data were available for direct head-to-head comparisons of antiplatelet drugs.

Conclusion: Antiplatelet agents probably reduce myocardial infarction and increase major bleeding, and may increase minor bleeding in CKD and haemodialysis patients. The treatment effect of direct head-to-head comparisons of antiplatelet drugs is very uncertain an rarely reported.
