Purpose: In our study, we aimed to study the predictive value of the CHADS2-VA2Sc score used in the assessment of the risk of injury in patients with acute coronary syndrome (ACS) and atrial fibrillation. Tools and Methods: Between January 2014 and February 2015, 251 patients followed with the diagnosis of ACS were included in the study in a row. The CHADS2-VA2Sc scores of patients were calculated prior to departure and were studied in three groups, ≤1, 2-4, ≥5 according to the scores. The primary end point was determined as the cause of mortality. Patients were followed in the middle of 62 months (25-75. persantil: 42-69 months). Cox regression analysis was conducted to determine the independent predictive parameters of mortality. Results: In total, 82 patients (32.7%) died during the follow-up period of 251 patients included in the study. 5 years of total caused mortality CHADS2-VA2Sc score ≥5 in the patient group was significantly higher than the other patients (3.7% vs. 22.4% vs. 71.4%). The Kaplan-Meier Survival Analysis showed significantly lower 5-year survival rates for patients with CHADS2-VA2Sc score ≥5. In Cox regression analysis for the determination of independent predictors in two separate models, the SYNTAX score (SS), the CHADS2-VA2Sc score (continuous variable) (Hazard ratio [HR]: 1.570, 95% confidence range [GA]: 1.358-1.815, P<0.001), and the CHADS2-VA2Sc score ≥5 (HR:4.710, 95% GA: 2.997-7.403, P <0.001) were determined as the independent predictors of all caused mortality for 5 years. The result: Our study found that patients with high CHADS2-VA2Sc scores had an increased risk of mortality in a 5-year long-term follow-up. It has been shown that the CHADS2-VA2Sc score account, which does not require any calculator algorithm, can be a simple, practical and valuable score system that can be used as an independent predictor of long-term mortality in ACS patients.
