The goal of this observational study is to evaluate the association between post-coronary angiography IMR and medium-term clinical prognosis in patients with acute myocarditis. The main question it aims to answer is:
Is there a correlation between impaired microcirculation and the occurrence of serious clinical events in this population of patients?
Male or female patients over the age of 18.
Patients hospitalized between June 2015 and July 2025.
Electrocardiographic abnormalities (ST-segment elevation or depression, T-wave inversions, conduction disturbances such as type 3 atrioventricular block),
Elevated troponin levels,
Absence of coronary artery disease confirmed by coronary angiography
Myocarditis secondary to immunotherapy
Presence of documented coronary artery disease (coronary angiography or cardiac CT)
Presence of cardiomyopathy (hypertrophic cardiomyopathy, dilated cardiomyopathy)
