Effect of Coronary Collaterals on Microvascular Obstruction as Assessed by Magnetic Resonance Imaging in Patients With Acute ST-Elevation Myocardial Infarction Treated by Primary Coronary Intervention

The aim of this study was to determine whether angiographically visible collaterals before reperfusion are associated with beneficial effects on infarct size, microvascular obstruction, and left ventricular function as measured by magnetic resonance imaging (MRI) in patients with ST-elevation myocar...

Zusammenfassung:	The aim of this study was to determine whether angiographically visible collaterals before reperfusion are associated with beneficial effects on infarct size, microvascular obstruction, and left ventricular function as measured by magnetic resonance imaging (MRI) in patients with ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). We examined 235 patients with STEMI and symptoms
