Li et al reported the C2HEST score for predicting incident atrial fibrillation in an Asian patient. The mC2HEST score involves the addition of a factor for a younger patient age.
Patient selection: Asian adult
Parameters:
(1) coronary artery disease (C)
(2) COPD (C)
(3) hypertension (H)
(4) elderly (E)
(5) systolic heart failure (S)
(6) thyroid disease (hyperthyroidism, T)

total score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 8
• The higher the score the greater the risk of atrial fibrillation.
Performance:
• The area under the ROC curve is 0.81.
