The Microcirculation in Acute Myocardial Infarction (Micro-AMI) (Micro-AMI)

October 27, 2014 updated by: Elisa McAlindon, University of Bristol
This study investigates the association between the microvascular resistance at the time of primary percutaneous intervention, with microvascular obstruction on CMR and blood markers of myocardial damage.
