The predictive value of PRECISE-DAPT score for arrhythmic complications in patients with ST-elevation myocardial infarction

Abstract

Objective: 

To investigate the predictive value of the PRECISE-DAPT score for the development of arrhythmias in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Method: 

A total of 706 patients with a diagnosis of ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention were enrolled to the study. The patients were divided into two groups according to the PRECISE-DAPT score (PRECISE-DAPT score ≥25 and PRECISE-DAPT score <25). The patients were compared in terms of in-hospital arrhythmia.

Results: 

High-degree atrioventricular block (second-degree Mobitz II or third-degree atrioventricular block) (17.2% vs. 4.9%; P < 0.001), ventricular tachycardia (11.2% vs. 4.6%; P = 0.005) and atrial fibrillation (13.8% vs. 3.1%; P < 0.001) rates were statistically higher in patients with higher PRECISE-DAPT score (≥25). There was no difference between the groups in terms of ventricular fibrillation (9.5% vs. 8.3%; P = 0.678). In multivariable logistic regression analysis; PRECISE-DAPT Score was independently associated with high-degree atrioventricular block (odds ratio: 6.38, P < 0.001) and atrial fibrillation (odds ratio: 4.33, P < 0.001).

Conclusion: 

The PRECISE-DAPT score was associated with high-degree atrioventricular block and atrial fibrillation in patients with ST-segment elevation myocardial infarction underwent percutaneous coronary intervention.
