Aim. The aim of our study was to assess clinical characteristics, etiologies, and outcome of patients with myocardial infarction in the absence of significant epicardial coronary artery stenosis, compared to patients with significant coronary lesions.
Methods. We included 124 patients, admitted to our intensive care unit for myocardial infarction. We collected demographic data, clinical characteristics, medical history, symptoms, biological parameters, electrocardiographic and imaging findings, and hospital outcome.
Results. Eight percent of patients admitted for myocardial infarction had angiographically normal coronary arteries, etiology was clear in only 30 percent of these patients. There was significantly more women, younger patients and lower body mass index in the normal coronary arteries group versus the abnormal coronary arteries group respectively. We noticed tendency toward higher mortality in the abnormal coronary arteries group.
Conclusion. Our findings show that myocardial infarction with normal coronary arteries
remains an entity that needs further exploration to fully understand the mechanism of ischemia permitting consequently a better management.
