C2HEST and Taiwan AF Scores for Prediction of Incident AF

C2HEST and Taiwan atrial fibrillation (AF) scores can predict the risk of incident AF. (A) The calculation tables of the C2HEST score and incidence of AF (per 1,000 person-years). (B) The calculation table of the Taiwan AF score. (C) The annual risk of AF based on the Taiwan AF score. Adapted with permission.8,9 C2HEST = coronary artery disease or chronic obstructive pulmonary disease (1 point each); hypertension (1 point); elderly (age ≥75 years, 2 points); systolic heart failure (2 points); thyroid disease (hyperthyroidism), 1 point); CAD = coronary artery disease; COPD = chronic obstructive pulmonary disease; ESRD = end-stage renal disease; HF = heart failure.
