摘要: Objective To evaluate the impact of periprocedural myocardial infarction (PMI) on long-term survival after coronary revascularization in patients with chronic total occlusion (CTO). Background Little is known about clinical PMI cardiac mortality CTO stable angina. Methods We analyzed data from 927 and angina who were treated artery bypass grafting (CABG, n = 367) or percutaneous intervention (PCI, n = 560). was defined as a peak CK-MB ≥ 3 times upper limit normal (ULN) PCI CK-MB ≥ 5 ULN CABG. The primary outcome death (PMI group, n = 118 [12.7%]) without (no-PMI n = 809 [87.3%]) revascularization. Results During median follow-up 42 months, occurred 118 (12.7% overall study population). Fifty-nine (10.5% subgroup) 59 CABG (16.1% suffered PMI. In multivariate analysis, group no-PMI had similar incidence (hazard ratio [HR] 0.57; 95% confidence interval [CI] 0.20 to 1.62; P = 0.29). Conclusions PMI may not be associated increased CTO. © 2015 Wiley Periodicals, Inc.
