The impact of successful chronic total occlusion percutaneous coronary intervention on long-term clinical outcomes in real world.

Successful revascularization by PCI may bring more clinical benefits. The presence of low left ventricular ejection fraction (LVEF) and LM-disease was associated with an incidence of cardiac death; CTO revascularization was a protected predictor of cardiac death. Successful revascularization by PCI offered CTO patients more clinical benefits, manifested by lower incidence of cardiac death during follow-up. The presence of LVEF < 0.5 and left main coronary artery disease (LM disease) was associated with an incidence of cardiac death; CTO revascularised was a protected predictor of cardiac death.
