Abstract
Background: The effect of remote ischemic preconditioning (RIPC) on periprocedural myocardial damage (pMD) in patients undergoing percutaneous coronary intervention (PCI) is controversial. The aim of this study was to investigate the effect of RIPC or intravenous nicorandil on pMD following elective PCI in a subgroup of patients with complex coronary lesions from a multicenter randomized controlled trial. Methods and Results: Patients with stable angina who underwent elective PCI were assigned to 3 groups: control, upper-limb RIPC or intravenous nicorandil. The major outcome was pMD incidence following PCI, with pMD defined as an elevated level of high-sensitivity cardiac troponin T or creatine kinase myocardial band at 12 or 24 h after PCI. A total of 171 patients with complex coronary lesions (ACC-AHA coronary classification type B2 or C) were analyzed. The incidence of pMD following PCI was significantly lower in the RIPC group than in the control group (44.4% vs. 66.1%; P=0.023). The adjusted odds ratio (95% confidence interval) for pMD in the RIPC vs. the controls was 0.41 (0.18−0.94). The incidence of pMD in the nicorandil group was not significantly reduced compared with the control groups. Conclusions: This substudy suggested that RIPC prior to PCI prevented pMD in patients with complex coronary lesions. Further investigation in a multicenter prospective study is needed to confirm these results.
