Stress Cardiac MRI in Women With Myocardial Infarction and Nonobstructive Coronary Artery Disease

ConclusionsAbnormal perfusion on sCMR is common among women with MINOCA. Abnormal perfusion usually co‐localized with LGE and/or T2+ when present. Variability in LGE pattern leads to uncertainty about whether the finding of abnormal perfusion was cause or consequence of the tissue state leading to LGE. Low MPRI, possibly indicating diffuse microvascular disease, was observed with and without LGE and T2+. Multiple mechanisms may lead to abnormal perfusion on sCMR. Microvascular dysfunction may contribute to the pathogenesis of and coexist with other causes of MINOCA.
