Study design:
The registry of Myocardial Infarction with Non-obstructive Coronary Arteries in the Turkish population (MINOCA-TR) is a nationwide, multicenter, prospective, and observational cohort study of patients with a de novo myocardial infarction (MI) presentation. A total of 32 invasive cardiology centers (eighteen university, ten state, and four private hospitals) around Turkey participated to the study. Patient recruitment was performed between March to June 2018. Patients without a known history of prior coronary revascularization who underwent a diagnostic coronary angiography procedure with a possible diagnosis of MI were screened and included in the study population. The aim of this screening was to obtain real-life data and prevent potential bias in the clinical context. A sub-study of the MINOCA-TR registry, this paper focuses on the prevalence of AF in the MINOCA-TR study population.4 The study population was divided into two groups, the AF and non-AF groups, based on their presenting rhythm at admission. Demographic, clinical, and angiographical data of the MINOCA-TR study population was recorded and compared. The study protocol of the MINOCA-TR was approved by the Clinical Research Ethical Committee of Dokuz Eylul University and was registered withwww.clinicaltrials.gov(NCT03364387).
