Myocardial infarction with nonobstructive coronary arteries (MINOCA): Potential mimics and causes
| In a patient with a cardiac troponin level > 99th percentile, a rise or fall of troponin, and objective evidence of ischemia, consider the following: | |
|---|---|
| Mimics (not MINOCA) Myocarditis | Causes of MINOCA Coronary microvascular disease |
| Takotsubo syndrome Other cardiomyopathies Overlooked obstructive disease: distal or small epicardial vessel occlusions not well visualized on angiography, a positive fractional flow reserve (ie, ≤ 0.80) in a moderate lesion | Plaque disruption (type 1 myocardial infarction) Supply-demand mismatch (type 2 myocardial infarction without obstruction) Spontaneous coronary artery dissection Coronary vasospasm Thromboembolic disease |
