Popis: Background Chronic total occlusion (CTO) in a non-infarct-related artery (IRA) is one of the risk factors for mortality after acute myocardial infarction (AMI). However, there are limited data comparing the long-term outcomes of patients underwent successful percutaneous coronary intervention (s-PCI) with patients having medical therapy (MT) in CTO lesion after AMI PCI. Methods We retrospectively enrolled 330 patients (n=166 in s-PCI group and n=164 in MT group) with CTO in a non-IRA from a total of 4372 patients who underwent PCI after AMI from July 2011 to July 2019 in our center (Figure 1). Propensity matching (119 matched pairs) was used to adjust for baseline differences. Major adverse cardiovascular and cerebrovascular events (MACCEs) on follow-up were defined as the composite of cardiac death, all cause death, myocardial infarction (MI), stroke and any revascularization. Kaplan-Meier analysis were used to evaluate the long-term outcomes between s-PCI and MT group. Results The patients in MT group were older, more likely to be diagnosed as STEMI, had lower eGFR and higher peak troponin T level during AMI compared with s-PCI group. Furthermore, in MT group, the involvement of LAD as IRA (50.6% vs 38.6%, p=0.028) and LCX as CTO vessel (45.1% vs 27.1%, p=0.001) was more frequent than in s-PCI group, and thus the involvement of LAD as CTO vessel was less frequent (28.9% vs 39.8%, p Conclusions In our center, s-PCI of CTO in non-IRA after AMI PCI showed better long-term cardiac survival as compared with MT. Moreover, patients with low LVEF may be benefit from CTO PCI in non-IRA. Funding Acknowledgement Type of funding sources: None. Flow chart of the studyKaplan-Meier analysis between two groups
