Changes in the CHA₂DS₂-VAS_C score as a predictor of incident atrial fibrillation in older Chinese individuals: the AF-CATCH study.

ABSTRACT:

Aims

Incidence of atrial fibrillation is highly associated with age and cardiovascular co-morbidities. Given this relationship, we hypothesized that the dynamic changes resulting in an increase in the CHA₂DS₂-VAS_C score over time would improve the efficiency of predicting incident atrial fibrillation on repeated screening after a negative test.

Methods and results

We investigated in an analysis of the AF-CATCH trial [quarterly vs. annual electrocardiogram (ECG) screening for atrial fibrillation in older Chinese individuals] data, the association between the changes in the CHA₂DS₂-VAS_C score from baseline to end-of-study visit and the risk of incident atrial fibrillation. Participants without a history of atria
