Background Coronary artery disease (CAD) is highly prevalent in patients with chronic kidney disease and is a common cause of mortality in end-stage renal disease. Thus, patients with end-stage renal disease are routinely screened for CAD before renal transplantation. The usefulness of revascularization before transplantation remains unclear. We hypothesize that there is no difference in all-cause and cardiovascular mortality in waitlisted renal transplant candidates with CAD who underwent revascularization versus those treated with optimal medical therapy before transplantation. Methods and Results This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. Risk of bias was assessed using the modified Newcastle-Ottawa Scale and Cochrane risk of bias tool. The primary outcome of interest was all-cause mortality. Eight studies comprising 945 patients were included (36% women, mean age 56 years). There was no difference in all-cause mortality (risk ratio [RR], 1.16 [95% CI, 0.63-2.12), cardiovascular mortality (RR, 0.75 [95% CI, 0.29-1.89]), or major adverse cardiovascular events (RR, 0.78 [95% CI, 0.30-2.07]) when comparing renal transplant candidates with CAD who underwent revascularization versus those who were on optimal medical therapy before renal transplant. Conclusions This meta-analysis demonstrates that revascularization is not superior to optimal medical therapy in reducing all-cause mortality, cardiovascular mortality, or major adverse cardiovascular events in waitlisted kidney transplant candidates with CAD who eventually underwent kidney transplantation.
