BackgroundRemote ischemic conditioning (RIC) has been recognized an emerging non-invasive approach for preventing acute kidney injury (AKI) in patients undergoing either elective coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI). On the other hand, accumulating evidence has indicated the involving role of pre-CABG contrast usage for coronary angiography in post-surgery AKI risk. Along with the shortening time delay of CABG after coronary angiography, and the prevalent hybrid coronary revascularization (HCR), the AKI prevention by RIC has faced challenges following coronary revascuralization.MethodsRandomized controlled trials (RCTs) were searched from Pubmed, EMBase, and Cochrane library (until May 2016). The primary outcome was postoperative AKI. The second outcomes were included the requirement for renal replacement therapy (RRT), and in-hospital or 30-day mortality.ResultsTwenty eligible RCTs (CABG, 3357 patients; PCI, 1501 patients) were selected. RIC significantly halved the incidence of AKI following PCI when compared with controls [n = 1501; odds ratio (OR) = 0.51; 95% CI, 0.32 to 0.82; P = 0.006; I2 = 29.6%]. However, RIC did not affect the incidence of AKI following CABG (n = 1850; OR = 0.94; 95% CI, 0.73 to 1.19; P = 0.586; I2 = 12.4%). The requirement for RRT and in-hospital mortality was not affected by RIC in CABG (n = 2049, OR = 1.04, P = 0.87; n = 1920, OR = 0.89, P = 0.7; respectively).ConclusionsOur meta-analysis suggests that RIC for preventing AKI following CABG has faced with challenges in terms of AKI, the requirement for RRT, and mortality. However, RIC shows a renoprotective benefit for PCI. Hence, our findings may infer the preserved renal effects of RIC in CABG with preconditioning before the coronary angiography, or in HCR.
