Early change in invasive measures of microvascular function can predict myocardial recovery following PCI for ST-elevation myocardial infarction

Abstract

Changes of the coronary microcirculation in the first day after PPCI are associated with 6-month ejection fraction and myocardial salvage. Depressed CFR at 24 h is associated with CMR imaging indices of MVO and haemorrhage and elevated endothelin levels.
