Objective:To access the benefits and harms of remote ischemic preconditioning(RIPC) in patients undergoing cardiac surgery with cardiopulmonary bypass.Methods:An electronic and manual search of literature published before Mar 2020 was conducted using Pubmed, EMBASE, Cochrane Library for randomized controlled trials(RCTs), CNKI, CBM, WanFang and VIP. 23 studies involving in 5 025 participants were included. Patients were randomly assigned to either remote ischemic preconditioning group(n=2 524) or control group(n=2 521). Remote ischemic preconditioning consisted of 3-4 cycles of lower limbs or upper limbs ischemia and reperfusion with an automated cuff inflator. Clinical data and the levels of injury biomarkers were collected. The main outcomes were the incidence of adverse events, mortality in the hospital, and the post-operative troponin concentration. The effective values of dichotomous variables or continuous variables were estimated by Relative risk( RR) or by mean differences( MD), standardized mean differences( SMD) with 95% confidence intervals( CI) respectively. Results:In general risk of bias varied from low to moderate risk of bias across included studies, and insufficient detail was provided to inform judgement in several cases. There were no significant differences between the two groups with regard to all-cause mortality in hospital( RR=1.27, 95% CI: 0.84-1.91, P=0.26), no-fatal myocardial infarction( RR=0.92, 95% CI: 0.79-1.07, P=0.27) , new stroke( RR=0.96, 95% CI: 0.61-1.50, P=0.84), new atrial fibrillation( RR=0.98, 95% CI: 0.83-1.15, P=0.77) and acute renal failure( RR=1.01, 95% CI: 0.90-1.14, P=0.83). Conclusion:There is no evidence that RIPC has a treatment effect on clinical outcomes(measured as all-cause mortality in hospital, no-fatal myocardial infarction, new stroke, new atrial fibrillation, and acute renal failure). More research should be designed to confirm the effect of RIPC on myocardial protection with cardiopulmonary bypass.
