Previous studies have investigated inflammation as a NOAF predictor. The Naples prognostic score (NPS) is a novel marker of inflammation and nutritional status. Objective: The objective of this study was to evaluate the predictive power of the NPS for NOAF. Methods: This study enrolled 1537 consecutive STEMI who underwent pPCI. The patients who presented NOAF during hospital admission and those who remained in sinus rhythm (RSR) were compared in terms of baseline characteristics. Univariate and multivariate analyses were carried out to identify variables predicting NOAF development, and p< 0.05 was considered statistically significant. Results: NOAF was detected in 7.74% (n: 119) of the participants. The mean age (67.03±13.48 vs 57.84±11.31; p <0.001) and NPS (2.53±1.17 vs 2.25±1.10, p=0.008) were significantly higher in the NOAF group. Multivariate analysis revealed age (Odds ratio [OR]: 1.045 for a year, 95% confidence interval [CI]: 1.019–1.071, p=0.001), NPS (OR: 1.645, 95% CI: 0.984–2.748, p=0.037) and left atrial dimensions (OR: 2.542 for cm, 95% CI: 1.488–4.342, p=0.001) as independent predictors of NOAF. Conclusions: The NPS was an independent predictor of NOAF in STEMI patients, in addition to classical factors such as age and left atrial dimensions. This score, mostly related to an inflammatory burden, may help to predict NOAF incidence and select better potential therapies aimed at abating inflammation after myocardial infarction.eninfo:eu-repo/semantics/closedAccessAngioplastyAtrial FibrillationMyocardial InfarctionPrognosisArticle10.36660/abc.202406711226404989242-s2.0-105008306496Q2WOS:001509557700001Q3
