The Relationship Between PRECISE-DAPT Score and Spontaneous Reperfusion of Infarct-Related Artery in Patients with ST-Segment Elevation Myocardial Infarction.

Objective: Spontaneous reperfusion (SR) presence and a low PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent Dual Anti Platelet Therapy (PRECISE-DAPT) score in patients with acute coronary syndrome have been associated with favorable clinical outcomes. This study aimed to investigate the relationship between SR and this score.

Methods: The study included 436 patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). Thrombolysis in myocardial infarction (TIMI) III blood flow presence in the infarct-related artery (IRA) before primary percutaneous coronary intervention (PCI) was defined as SR. Patients were categorized into two groups based on the presence (n = 49) or absence (n = 387) of SR. The PRECISE-DAPT score was computed for each patient using the web-based calculator.

Results: The group with SR had a lower frequency of hyperlipidemia and a higher ejection fraction (EF) at admission. Conversely, the group without SR presented with higher values of glucose, troponin, creatine kinase-myocardial band (CK-MB), and PRECISE-DAPT score. The no-reflow phenomenon and elevated SYNergy between PCI with TAXUS and Cardiac Surgery (SYNTAX-I) scores were higher in the group without SR than in the one with SR. Multivariate regression analysis indicated that a high PRECISE-DAPT score was an independent predictor of the absence of SR (odds ratio: 0.96, P = 0.04).

Conclusion: The PRECISE-DAPT score is an independent predictor of the presence of spontaneous reperfusion in patients who experienced STEMI.
