Why the study?
Up to 50% of acute MI patients present with microvascular dysfunction after successful PCI, leading to worse outcomes, prompting a critical appraisal of emerging invasive microvascular resistance indices.
Do invasive microvascular resistance indices correlate with microvascular dysfunction and predict clinical outcomes in patients with acute myocardial infarction?

IMR and HMR aid post-MI risk stratification beyond CMR; confirms their independent prognostic value in systematic review.
Do invasive microvascular resistance indices correlate with microvascular dysfunction and predict clinical outcomes in patients with acute myocardial infarction?
Invasive microvascular resistance indices, particularly IMR and HMR, are valuable tools that correlate with myocardial damage on CMR and predict adverse clinical outcomes following acute MI.
