Noninvasive Index of Microvascular Resistance as a Predictor of Left Ventricular Performance Recovery in Patients with STEMI Undergoing Primary PCI

Abstract

Background: Coronary microvascular function can predict the infarct size and Left Ventricular (LV) functional recovery in patients diagnosed with ST-Elevation Myocardial Infarction (STEMI). Multiple invasive and non-invasive methods are used to evaluate coronary microvascular function. The Non-invasive Index of Microvascular Resistance (NiMR) is a method to evaluate microvascular resistance.
