  1. TG, triglyceride; ApoA1, apolipoprotein A1; ApoB, apolipoprotein B; TC-p, total particles of cholesterol; TC, total cholesterol; Lp(a), lipoprotein a; Lp(a)-p, particles of Lp(a); LDL-C, low-density lipoprotein cholesterol; LDL-p, particles of LDL; LDL-size, average diameter of LDL-p; LDL-p-corr and LDL-C-corr, corrected LDL-p and LDL-C; HDL-C, high-density lipoprotein cholesterol; HDL-p, particles of HDL; non-HDL-C, none high-density lipoprotein cholesterol; non-HDL-p, particles of non-HDL; non-HDL-p-corr and non-HDL-C-corr, corrected non-HDL-p and non-HDL-C
  2. Lp(a) = Lp(a)-p*0.4167; LDL-p-corr = LDL-p – Lp(a)-p; LDL-C-corr = LDL-C – 0.3*Lp(a); non-HDL-p = TC-p – HDL-p; non-HDL-p-corr = non-HDL-p – Lp(a)-p; Non-HDL-C = TC – HDL-C; non-HDL-C-corr = non-HDL-C – 0.3*Lp(a)
  3. TG, ApoB, TC-p, Lp(a)-p, Lp(a), LDL-C-size, HDL-C-p, HDL-C and non-HDL-C-corr were skew distribution and shown as median (25th percentile, 75th percentile). Before the Student’s t-test for the difference between groups, the nonnormal distribution variables were converted into natural logarithm form
  4. aOverweight was defined as body mass index (BMI) > 28 (BMI = weight (Kg) / height (m))
  5. bFamily history was defined as the age of onset of coronary heart disease less than 55 for men and less than 65 for women, in the immediate family members of patients
  6. cTIMI flow classification was used to evaluate coronary artery perfusion by coronary angiography. It was divided into grade 0 (no perfusion); Grade 1 (infiltration without perfusion); Grade 2 (partial perfusion) and Grade 3 (complete perfusion)
