Long-term outcomes of staged recanalization for concurrent chronic total occlusion in patients with ST-segment elevation myocardial infarction after primary percutaneous coronary intervention.

ABSTRACT:

Background

In patients with acute ST-segment elevation myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention (PCI), approximately 10% are concomitant with a chronic total occlusion (CTO) in a non-culprit vessel. However, the impact of staged CTO recanalization on prognosis in this cohort remains disputable. This study aimed to compare the long-term outcomes of staged CTO recanalization versus medical therapy in patients with STEMI after primary PCI.

Methods

Between January 2005 and December 2016, a total of 287 patients were treated with staged CTO-PCI (n = 91) or medical therapy (n = 196) after primary PCI in our center. The primary endpoint was major adverse cardiovascular and cerebrovascular event (MACCE), defined as a composit
