Myocardial Hemorrhage After Acute Reperfused ST-Segment–Elevation Myocardial Infarction

Myocardial Hemorrhage After Acute Reperfused ST-Segment-Elevation Myocardial Infarction: Relation to Microvascular Obstruction and Prognostic Significance.

BACKGROUND The success of coronary reperfusion therapy in ST-segment-elevation myocardial infarction (MI) is commonly limited by failure to restore microvascular perfusion. METHODS AND RESULTS We performed a prospective cohort study in patients with reperfused ST-segment-elevation MI who underwent cardiac magnetic resonance 2 days (n=286) and 6 months (n=228) post MI. A serial imaging time-co...

Intramyocardial hemorrhage in spontaneously reperfused myocardial infarction.

OBJECTIVE. The presence of intramyocardial hemorrhage (IMH) is frequent in patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PPCI). We aim for the presence IMH using cMRI in patients who presented AMI and did not undergo PPCI or thrombolysis. Cardiac magnetic resonance has proven to be a highly sensitive method for detect its presence in the ...

Predictors of Intramyocardial Hemorrhage After Reperfused ST‐Segment Elevation Myocardial Infarction

BACKGROUND Findings from recent studies show that microvascular injury consists of microvascular destruction and intramyocardial hemorrhage (IMH). Patients with ST-segment elevation myocardial infarction (STEMI) with IMH show poorer prognoses than patients without IMH. Knowledge on predictors for the occurrence of IMH after STEMI is lacking. The current study aimed to investigate the prevalence...
