Abstract
Myocardial infarction with non-obstructive coronary arteries (MINOCA) constitutes a significant subset of acute myocardial infarctions (AMI) with uncertain prognostic markers. Early risk assessment is crucial to identify MINOCA patients at risk of adverse outcomes. This study aimed to evaluate the predictive capacity of the PRECISE-DAPT score in assessing short- and long-term prognoses in MINOCA patients presenting with ST-segment elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI). Among 741 MINOCA patients, the PRECISE-DAPT score was computed to analyze its association with in-hospital and follow-up major adverse cardiovascular events (MACE). Parameters showing significance in MACE (+) groups underwent statistical analysis: univariate logistic regression for in-hospital events and univariate Cox regression for follow-up events. For statistical significance, a predefined level of α = 0.05 was adopted. Parameters demonstrating significance proceeded to multiple logistic regression for in-hospital events and multivariate Cox regression for follow-up events. In-hospital MACE occurred in 4.1% of patients, while 58% experienced follow-up MACE. Hemoglobin levels and the PRECISE-DAPT Score were identified as independent parameters for in-hospital MACE. Furthermore, ejection fraction (EF%) and the PRECISE-DAPT Score emerged as independent predictors of follow-up MACE. The study revealed that a higher PRECISE-DAPT score was significantly associated with increased risks of both in-hospital and long-term major adverse cardiovascular events in MINOCA patients presenting with acute coronary syndrome (ACS), underscoring the score's potential in risk stratification for this patient cohort. _ PRECISE-DAPT score predicts MACE risk in MINOCA patients. _ Hemoglobin level and PRECISE-DAPT score predict in-hospital MACE. _ Ejection fraction and PRECISE-DAPT score predict long-term MACE.
