Summary

This study aim to investigate the predictive value of CMR parameters: infarct size (IS), intramyocardial hemorrhage, microvascular obstruction, area at risk and CMR derived strain parameters with the Major Adverse Cardiovascular Events (MACEs) and myocardial remodeling afterinfarction.

Detailed description

Investigators will enroll 500 patients with STEMI after PCI who were admitted to the Chinese PLA General Hospital and other eight hospitals across China: Wuhan Asia Heart Hospital; the First People's Hospital of Yunlin; Chaoyang Hospital, Capital Medical University; Hainan Hospital of PLA General Hospital; the Second Affiliated Hospital of Nanchang University; the Second Hospital of Hebei Medical University; Guizhou Provincial People's Hospital; Affiliated Hospital of Zunyi Medical College between January 2014 and December 2019. CMR was performed at 7 days and 6 months after primary PCI to assess the final infarction size(IS), microvascular obstruction (MVO), intramyocardial hemorrhage(IMH), area at risk (AAR) and related strain parameters. All patients will be followed up by 5 years after adimission. Cardiovascular events concluded stroke, repeat revascularization, rehospitalization for acute heart failure, nonfatal myocardial infarction, and all cause death. All adverse clinical events as well as study end points were monitored and adjudicated by the independent event committee.
