Coronary chronic total occlusions (CTOs) are considered to increase the risk of adverse clinical outcomes. The purpose of this study was to evaluate whether long-term clinical outcomes could be improved by successful percutaneous coronary intervention (PCI) over optimal medical therapy (OMT) in CTO patients.
patients with CTO lesions undergoing PCI at the First Affiliated Hospital of Nanjing Medical University from January 2011 to December 2017 were enrolled. After someone were excluded due to CABG surgery, patients who met the enrollment criteria were divided into successful CTO-PCI group and CTO-OMT group based on the treatment received. The study primary endpoint was major adverse cardiac cerebrovascular events (MACCE), including cardiac death, recurrent myocardial infarction, unplanned revascularization, and stroke. The secondary endpoint was all-cause death.
