CHA₂DS₂-VASc scores predict mortality after hospitalization for atrial fibrillation.

Objective: The outcome of patients hospitalized for atrial fibrillation (AF) is relatively poor. We sought to determine the mortality rate and predictors of mortality following hospitalization for AF and to evaluate whether the CHA2DS2-VASc score was a predictor of mortality.

Methods: We examined the national database of Thailand residents who registered for government provided health insurance in 2005 and reviewed patient records from 2005 to 2010 to determine all-cause mortality.
