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.
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.
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
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.
