Microvascular obstruction is a major determinant of infarct healing and subsequent left ventricular remodelling following primary percutaneous coronary intervention

We studied the time-dependent relationships between microvascular obstruction (MO), infarct size, and left ventricular (LV) remodelling after acute myocardial infarction (MI).Forty-two consecutive patients with first-time ST-elevation MI, single-vessel disease, successfully treated with primary percutaneous coronary intervention (PCI) were included. Microvascular obstruction, infarct size, and LV remodelling were assessed by cardiac magnetic...
