Coronary Microvascular Obstruction
During the past decades, advances in percutaneous coronary intervention and antithrombotic therapy have improved the prognosis of patients with ST-segment–elevation myocardial infarction (STEMI). However, in a substantial number of STEMI patients, myocardial perfusion remains impaired despite successful recanalization of the infarct-related epicardial coronary artery, and this scenario has been...

fusion in STEMI patients and carries a high risk of complications, including increased rates of adverse remodeling, heart failure and death.16–23 Interestingly, previous studies have shown a reduction “in vivo” of the MVO rate in patients experiencing PIA.24–26 Of note, although it is already known that cardiovascular risk factors (CRFs) may limit the protective effects of IP in human models,27...

متن کاملMicrovascular obstruction is associated with greater infarct heterogeneity
Methods 21 patients post primary percutaneous coronary intervention for acute ST elevation myocardial infarction were prospectively enrolled and each had 3 MRI scans on a 1.5T GE Signa Excite scanner at 48 hours, 3 weeks and 6 months post infarction. A T1-weighted IR-GRE sequence was used for late gadolinium enhancement assessment of infarcted myocardium. Core infarct size (CIS) and gray zone (...
متن کاملIntramyocardial hemorrhage contributes to microvascular obstruction in acute myocardial infarction
Background Patients with hemorrhagic infarcts appear to constitute a high-risk group in acute myocardial infarction (AMI). However, the clinical implications of hemorrhagic versus non-hemorrhagic infarcts are currently unclear, warranting a more systematic and mechanistic approach towards understanding the underlying consequences. The question of whether hemorrhage is simply a bystander or cont...
