This study aimed to compare the long-term outcomes of patients with multiple CTOs and single CTO after PCI.Methods: This study cohort included stable CAD patients who were diagnosed with CTO and treated with PCI from a single center. The primary endpoint was all-cause death.Results: We retrospectively reviewed 670 consecutive patients with CTO-PCI. Among them, 539 patients had a single CTO, and 131 (19.7%) patients had multiple (at least two) CTOs. CTO revascularization was achieved in 470 (70.1%) patients. After a median follow-up duration of 33.7 months, the cumulative all-cause mortality (p = 0.037) and cardiac mortality (p = 0.003) were higher in patients with multiple CTOs than in those with a single CTO. In the multivariable model, multiple CTOs and left ventricular ejection fraction (LVEF) less than 40% were independent predictors for cardiac death (adjusted hazard ratio (HR) 2.53; P = 0.013 and adjusted HR 3.95; P < 0.001), while age older than 65 and LVEF less than 40% were independent predictors for all-cause death in CTO-PCI patients (adjusted hazard ratio (HR) 1.84; P = 0.035 and adjusted HR 2.54; P = 0.001).Conclusion: In CTO-PCI patients, long-term survival was associated with multiple CTOs, age and LVEF, but not with CTO revascularization.Keywords: coronary chronic total occlusion, percutaneous coronary intervention, clinical outcomes, cardiac death
