* Plus–minus values are mean ± SD. To convert the value for creatinine to micromoles per liter, multiply by 88.4.
AT denotes As Treated population, CABG denotes coronary-artery bypass grafting, COPD chronic obstructive
pulmonary disease, LVEF left ventricular ejection fraction, NYHA New York Heart Association, PCI percutaneous
coronary intervention, and TAVR transcatheter aortic-valve implantation.
†
The Society of Thoracic Surgeons (STS) score measures patient risk at the time of cardiovascular surgery on a
scale that ranges from 0% to 100%, with higher numbers indicating greater risk. An STS score higher than 10%
indicates very high surgical risk.
‡
The logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), which measures patient
risk at the time of cardiovascular surgery, is calculated with the use of a logistic-regression equation. Scores
range from 0% to 100%, with higher scores indicating greater risk. A logistic EuroSCORE higher than 20%
indicates very high surgical risk.
§
Frailty was determined by the surgeons according to prespecified criteria.
** Moderate or severe mitral regurgitation was defined as regurgitation of grade 3+ or higher.
