Measuring microvascular dysfunction directly after percutaneous revascularisation can predict the risk of complications in patients with ST-elevation MI, according to an international team of cardiologists.
Specifically, those with a low microvascular resistance reserve (MRR) score — which measures coronary mechanical reperfusion in small blood vessels irrespective of epicardial disease — were four times more likely to die from any cause or be rehospitalised.
