Impact of target vessel on long-term survival after percutaneous coronary intervention for chronic total occlusions

摘要: Background This study sought to investigate whether there is a differential prognostic effect of successful percutaneous coronary intervention (PCI) chronic total occlusions (CTO) according the target vessel CTO located in. Methods Between 1998 and 2007, 1,791 patients underwent PCI at three tertiary care centers in US, Italy, South Korea. Patients with CTOs multiple vessels or left main stem were excluded (n = 57). Of remaining 1,734 patients, 609 had anterior descending (LAD, 35.1%), 391 circumflex (LCX, 22.5%), 734 right artery (RCA, 42.3%). Five-year mortality need for bypass grafting (CABG) compared between vs. unsuccessful stratified by vessel. Results Procedural success was obtained 71.1% LAD 69.1% LCX 65.1% RCA (P 0.06). The mean follow-up duration 1,178 days. Kaplan–Meier estimates long-term 6.7% 11.0% 0.03), 5.5% 13.9% < 0.01), 6.6% 4.1% 0.80) LAD, LCX, respectively. After multivariate analysis, remained associated lower (HR 0.41, P 0.02) groups 0.32, 0.01). CABG after all (LAD 4.6% 16.0%, 0.01; 2.9% 18.2%, 0.01, 2.3% 8.4%, 0.01). Conclusion The results from this large contemporary cohort suggest that but not RCA, improved survival. © 2013 Wiley Periodicals, Inc.
