Glycemic Control Status and Long-Term Clinical Outcomes in Diabetic Chronic Total Occlusion Patients: An Observational Study

Figure 1

Study scheme. AMI: acute myocardial infarction; CABG: coronary artery bypass grafting; CTO: chronic total occlusion; LMCA: left main coronary artery; CTO-SR: successful CTO revascularization, a successful revascularization for the CTO vessel by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG); CTO-NSR: nonsuccessful CTO revascularization, patients failed CTO revascularization procedures or failed to try CTO revascularization (only took medicine). #Patients with manifestations of symptomatic stable angina or silent ischemia. A total of 989 (96.11%) patients completed the follow-up process.
