Myocardial Infarction with Non-obstructed Coronary Arteries: A Yet Barely Investigated Field with Several Unmet Clinical Needs

Acute Myocardial Infarction with Normal Coronary Arteries

IN THE DIAGNOSIS of myocardial infarction, selective coronary arteriography almost invariably demonstrates evidence of occlusive atherosclerosis. There have, however, been reports of cases where technically excellent coronary arteriograms have shown normal vessels and a variety of causes other than atherosclerosis have been incriminated.1-4 This problem has not been resolved but some evidence n...

Myocardial infarction with angiographically normal coronary arteries.

Myocardial Infarction with Normal Coronary Arteries (MINCA) is an important subgroup of myocardial infarction with a frequency of at least 3-4% of all myocardial infarctions. The interest and awareness of MINCA have increased recently due to the frequent use of coronary angiography, the description of Takotsubo stress cardiomyopathy and new sensitive troponin assays. Since myocarditis may mimic...

Fascination with myocardial infarction and normal coronary arteries.

and brain natriuretic peptide levels. Unlike the Masuda et al. study, atrial natriuretic peptide levels were unchanged, but brain natriuretic peptide levels decreased after enhanced external counterpulsation treatment as they did in the study of Masuda et al. The authors concluded that enhanced external counterpulsation improves myocardial perfusion, exercise performance and left ventricular di...
