CHADS2 and CHA2DS2VASc Scores in Patients with Cardiovascular Diseases Admitted to the Hospital

Background: CHADS2 and CHA2DS2VASc scores have been extensively studied as predictors of stroke in patients with atrial fibrillation. The components of these scores including age, gender, heart failure, diabetes mellitus, hypertension, prior TIA/stroke, and vascular disease, are all known as conditions associated with cardiovascular outcomes. We hypothesize that these scores can be used as predictors of outcomes in cardiovascular diseases.

Methods: We reviewed all admissions to the cardiology department in 1992-2015. Only the first admission was included in the analysis. CHADS2 and CHA2DS2VASc scores were calculated by the electronic medical record, and mortality data was extracted from the government civil registry.

Results: Total of 38,603 patients with first hospital admission to the cardiology department were analyzed. CHADS2 score was correlated with in-hospital, 30-day, 1-year and 5-year mortalities (Figure). CHA2DS2VASc score had similar correlation and did not contribute beyond CHADS2.

Conclusion: in patients with cardiovascular diseases admitted to the hospital, CHADS2 and CHA2DS2VASc Scores can be used as predictors of short- and long-term mortality.
