Cardiac magnetic resonance imaging improves prognostic stratification of patients with ST-elevation myocardial infarction and preserved ejection fraction.

ABSTRACT:

Aims

To evaluate the prognostic validity of clinical risk factors as well as infarct characterization and myocardial deformation by cardiac magnetic resonance (CMR) in ST-elevation myocardial infarction (STEMI) patients with preserved left ventricular ejection fraction (LVEF) following primary percutaneous coronary intervention (PCI).

Methods and results

This multicentre, individual patient-data analysis from two large CMR trials included 1247 STEMI patients. Cardiac magnetic resonance examinations were conducted 3 [interquartile range (IQR) 2-4] days after PCI. LVEF, infarct size, microvascular obstruction (MVO), and myocardial strain values were measured. Primary endpoint was defined as composite of major adverse cardiovascular events (MACE) including death, re-infarction,
