简介
Background
Myocardial haemorrhage is a prognostically important complication of acute ST-elevation myocardial infarction (STEMI). Persistence of haemoglobin degradation products within infarct scar tissue and the potential clinical significance have not been investigated.
Methods and Results
Patients who sustained an acute STEMI were enrolled in a cohort study (BHF MR-MI; ClinicalTrials.gov: NCT02072850). 211 patients (mean (SD) age 57 (11) years, 77% male) had evaluable T2* cardiac magnetic resonance (CMR) imaging (1.5 Tesla) 2 days 6 months post-MI. Myocardial haemorrhage was defined as a hypointense infarct core with T2* signal <20ms. At 2 days, 79 (37%) patients had evidence of myocardial haemorrhage. At 6 months, 47 (59%) patients had a hypointense infarct core and 32 (41%) did not. None of the patients had de novohaemorrhage after the first CMR scan. Clinical associates of a …
