Yildirim E, et al. - Including 706 patients receiving primary percutaneous coronary intervention for ST-segment elevation myocardial infarction, this study was performed to determine whether the PRECISE-DAPT score holds value for predicting the development of arrhythmias in such a patient population. Based on the PRECISE-DAPT score, two groups of patients were defined: PRECISE-DAPT score ≥ 25 and PRECISE-DAPT score < 25. Patients with higher PRECISE-DAPT score (≥ 25) showed statistically higher rates of high-degree atrioventricular block (second-degree Mobitz II or third-degree atrioventricular block), ventricular tachycardia and atrial fibrillation. The groups did not differ in terms of ventricular fibrillation. Findings revealed a link of the PRECISE-DAPT score with high-degree atrioventricular block and atrial fibrillation among the participants.
