TC total cholesterol, TG triglyceride, HDL-C high density lipoprotein cholesterol, LDL-C low density lipoprotein cholesterol, UA uric acid, Cr creatinine, FBG fasting blood glucose, HbA1C glycosylated hemoglobin, hsCRP high-sensitivity C-reactive protein, NT-proBNP N-terminal B-type brain natriuretic peptide precursor. The distribution of TG, hsCRP and BNP was non-normal distribution. The data were expressed as median (quartile 1, quartile 3), i.e. M (p25, p75). *: P < 0.05; **: P < 0.01
