Lipids, lipoproteins, apolipoproteins, and other risk factors in Chinese men and women with and without myocardial infarction.

One hundred and fifty-four male and 69 female Chinese patients, aged between 40 and 60 years, who had suffered myocardial infarction (MI) were investigated and compared with 216 men and 219 women who had no history or ECG evidence of coronary heart disease. The male MI patients had significantly raised levels of triglycerides (160 mg/dl), cholesterol (194 mg/dl), VLDL-CH (31 mg/dl), apolipoprotein B (122 mg/dl) and apolipoprotein E (4.7 mg/dl) and a lower apolipoprotein A-I level (126 mg/dl) than the control group (triglycerides 131, cholesterol 179, VLDL-CH 26, apo B 102, apo E4.2, and apo A-I 138 mg/dl). The women with MI also had higher values for the atherogenic lipids than the control group (triglycerides 175 vs. 134 mg/dl, cholesterol 218 vs. 186 mg/dl, LDL-CH 128 vs. 104 mg/dl, VLDL-CH 32 vs. 26 mg/dl, apo B 121 vs. 103 mg/dl and apo E 5.4 vs. 4.3 mg/dl), as well as lowered apolipoprotein A-I (128 vs. 144 mg/dl). The Lp(a) levels (men and women considered together) were significantly higher for the MI patients (34.3 mg/dl vs. 26.2 mg/dl). Anti-atherogenic lipoproteins such as HDL-cholesterol, HDL2-CH, HDL3-CH, phospholipids and apolipoprotein A-II, C-II and C-III showed no difference between the groups.
