Sum of risk points	Risk rank	Postoperative AF risk
<14	Low	< 17 percent
14-31	Medium	17 to 52 percent
>31	High	> 52 percent

AF: atrial fibrillation; COPD: chronic obstructive pulmonary disease; ACE inhibitors: angiotensin converting enzyme inhibitors; NSAIDs: nonsteroidal antiinflammatory drugs.
* To calculate the estimated risk of postoperative atrial fibrillation, the sum of the risk points is determined. Scores are stratified into low risk (<14 points; AF incidence <17 percent), medium risk (14 to 31 points; AF incidence 17 to 52 percent) and high risk (>31 points; AF incidence >52 percent).
