    The study evaluated the CHA2DS2-VA score's effectiveness in predicting mortality and ventricular arrhythmias in ICD patients with ischemic heart disease and dilated cardiomyopathy.

  • 2

    A total of 1,626 ICD recipients were analyzed, with a median follow-up of 7.5 years, revealing a 46% all-cause mortality rate.

  • 3

    Higher CHA2DS2-VA scores correlated with increased all-cause and cardiovascular mortality in both ischemic heart disease and dilated cardiomyopathy patients.

  • 4

    Each one-point increase in CHA2DS2-VA score raised the mortality risk significantly, indicating its utility in mortality risk stratification.

  • 5

    The CHA2DS2-VA score did not predict ventricular arrhythmias, suggesting it should not be used for arrhythmic risk assessment in these patients.
