What are the risk markers for ventricular arrhythmia and 1-year prognosis in patients with MINOCA and normal ejection fraction?
In patients with MINOCA and normal ejection fraction, LGE transmural extent and admission ST elevation predict in-hospital ventricular arrhythmias, though 1-year arrhythmic prognosis is excellent.
AIM: To assess the arrhythmic determinants and prognosis of patients presenting with myocardial infarction and non-obstructive coronary arteries (MINOCA) with normal ejection fraction (EF). METHODS: = 50). Ventricular events occurring during hospitalization were recorded and the entire population was followed-up at 1 year. RESULTS: = 0.004] were independent predictors of ventricular arrhythmic events, irrespective of the diagnosis class. Finally, no patient experienced sudden cardiac death or ventricular arrhythmia recurrence at 1-year. CONCLUSION: MINOCA patients with normal EF presented no 1-year cardiovascular events, irrespective of the CMR diagnosis class. LGE transmural extent and ST segment elevation at admission are risk markers of ventricular arrhythmia during hospitalization.
