The Association of a PRECISE-DAPT Score With No-Reflow in Patients With ST-Segment Elevation Myocardial Infarction.

This study aimed to evaluate the association of admission PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent Dual Anti Platelet Therapy (PRECISE-DAPT) score with the development of no-reflow (NR) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). In this observational, retrospective study, 335 consecutive STEMI patients who were treated with primary PCI were included. We classified the study population into 2 groups: patients with a PRECISE-DAPT score <25 and those with a PRECISE-DAPT score ≥25. Overall, 30 (8.9%) patients developed NR. The mean PRECISE-DAPT score (20.03 ± 15.32 vs 11.33 ± 12.18; P = .005) was significantly higher in cases who developed NR. Moreover, arrhythmic complications, in-hospital shock, and in-hospital mortality rates were significantly higher in patients with a PRECISE-DAPT score ≥25 compared to those with a PRECISE-DAPT score <25. According to a multivariable analysis, the PRECISE-DAPT score was found to be independently linked with NR (odds ratio: 2.87, with P = .015). To our knowledge, these data are the first in major medical science databases to determine the relationship between the PRECISE-DAPT score and the NR phenomenon in patients with STEMI undergoing primary PCI.
