Patients with suspected MINOCA have a favorable prognosis compared to those with obstructive CAD, but a trend toward worse outcomes compared to those without MI.
BACKGROUND: Suspected myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) occurs in ≈5% to 10% of patients with MI referred for coronary angiography. The prognosis of these patients may differ to those with MI and obstructive coronary artery disease (MI-CAD) and those without a MI (patients without known history of MI No-MI). The primary objective of this study is to evaluate the 12-month all-cause mortality of patients with MINOCA. METHODS: statistics. The primary outcome was 12-month all-cause mortality in patients with MINOCA, with secondary comparisons to MI-CAD and No-MI. RESULTS: =0.09). CONCLUSIONS: In the largest contemporary MINOCA meta-analysis to date, patients with suspected MINOCA had a favorable prognosis compared with MI-CAD, but statistically nonsignificant trend toward worse outcomes compared to those with No-MI.
