Data are presented as mean ± SD or number (percentage). Am-subgroup: morning-onset AMI; Pm-subgroup: noon-onset AMI; Eve-subgroup: night-onset AMI. Smoker: Past—the patient's smoking-quitting exceeds three months but had smoked at least five cigarettes a day in the past two years or nonsmokers within three months; Current—the patients had smoked at least five cigarettes a day for two years. Drinker: drinks more than 4 drinks a day. FPG: fasting plasma glucose; SCR: serum creatinine; CRP: C-reactive protein; TC: total cholesterol; TG: triglyceride; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; ALT: alanine aminotransferase; AST: aspartate transaminase. ∗Pm-subgroup vs. Am-subgroup; #Eve-subgroup vs. Am-subgroup.
