Data are presented as absolute numbers and percentages (for categorical variables) or mean value ± SD (for continuous variables) unless otherwise specified. BMI, body mass index; WC, waist circumference; HT, hypertension; DM, diabetes mellitus; CHD, coronary heart disease; MI, myocardial infarction; HF, heart failure; CKD, chronic kidney disease; PAD, peripheral arterial disease; PCI, percutaneous coronary intervention; EDD, left ventricular end-diastolic dimension; LVEF, left ventricular ejection fraction; LDL-C, low-density lipoprotein cholesterol; eGFR, estimated glomerular filtration rate (calculated via Modification of Diet in Renal Disease equation); HbA1c, glycated haemoglobin. Bold values indicate that the difference is statistically significant (P < 0.05).
