Numerical data are expressed as mean ± standard deviation or as median (95% confidence interval). The numbers in parenthesis denote the percentage. ACC/AHA CHF stage = American College of Cardiology/American Heart Association chronic heart failure stage; CABG = coronary artery bypass grafting; CAD = coronary artery disease; eGFR = estimated glomerular filtration rate; PCS = post-cardiovascular surgery.
