Abstract

Abstract: Background: Patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) and having concomitant atrial fibrillation (AF) have a greater risk of adverse short- and long-term outcomes and death compared with patients in the same setting but without AF. On the other hand, the predictive value of CHA2DS2-VASc score in terms of in-hospital mortality and periprocedural adverse events following PCI among patients with ACS and AF is unknown. Purpose: We retrospectively analyzed data of patients with the main admission diagnosis of ACS that underwent PCI and had AF during the 2004–2014 period from the large nationwide US National Inpatient Sample (NIS) database. Methods: A CHA2DS2-VASc score was calculated for each patient and incorporated into a multivariable-adjusted logistic regression to determine its independent impact on in-hospital outcomes consisting of death, acute kidney injury (AKI), bleeding, vascular injury, and stroke/transient ischemic attack (TIA). Results: A total of 283, 890 patients with AF who underwent PCI following ACS were included in the analysis. The average reported prevalence of the AF in the whole cohort was 10.0% with a significant trend (p<0.001) of increase during the observed 10-year period. The average age of the cohort was 72.1±11 years, 63.4% were male while the median CHA2DS2-VASc score was 3 (IQR 2–4). Crude rates of adverse in-hospital outcomes were significantly higher among patient groups with higher CHA2DS2-VASc score (Table 1). Following adjustment for baseline covariates, incremental increase in CHA2DS2-VASc score was independently associated with an increased odds of in-hospital death (OR 1.20, CI 95% 1.18–1.22), periprocedural vascular injury (OR 1.18, 95% CI 1.17–1.20), bleeding (OR 1.17, 95% CI 1.16–1.18), stroke/TIA (OR 1.17, 95% CI 1.15–1.19), and AKI (OR 1.05, 95% CI 1.04–1.06) (Figure 1). Conclusions: The CHA2DS2-VASc score provides important prognostic information in ACS patients with AF undergoing PCI and is independently associated with in-hospital death and periprocedural adverse events. Therefore, CHA2DS2-VASc score could be used as a practical and inexpensive tool for risk stratification in this population. Funding Acknowledgement: Type of funding source: None
