Continuous variables that satisfy normal distribution are expressed by mean and standard deviation, and continuous variables that do not satisfy normal distribution are expressed by median and quartile. Categorical variables are expressed by number and percentage.
AHF = acute heart failure, CA125 = carbohydrate antigen 125, CHD = coronary heart disease, DBP = diastolic blood pressure, HR = heart rate, LAD = left anterior descending branch, LCX = left circumflex branch, NT-proBNP = N-terminal pro-B-type natriuretic peptide, RCA = right coronary artery, SBP = systolic blood pressure.
