The effect of xuezhikang on postprandial triglyceride (TG) level was investigated in patients with coronary heart disease (CHD) after a high-fat meal (800 cal; 50 g fat). Fifty CHD patients were randomly divided into two groups to accept xuezhikang (xuezhikang group) 1200 mg/day (600 mg twice daily) or not (control group) on the base of routine therapy which included aspirin, metoprolol and fosinopril and nitrates during the whole 6 weeks following-up. Xuezhikang significantly reduced fasting serum total cholesterol (TC) (-20%), low-density lipoprotein cholesterol (LDL-C, -34%), TG (-32%) and apoB (-27%) levels, and raised fasting high-density lipoprotein cholesterol (HDL-C, 18%) and apoA-I (13%) levels (P<0.001). The postprandial serum TG levels at 2, 4 and 6 h decreased 32, 38 and 43%, respectively, in xuezhikang group (P<0.001). The TG area under the curve over the fasting TG level (TG-AUC) significantly decreased in CHD patients accepted xuezhikang with normal (less than 1.7 mmol/l) and elevated (1.74 to 2.92 mmol/l) fasting TG levels by 45 and 50%, respectively (P<0.001). Routine therapy had no significant effect on the fasting and postprandial lipid and apolipoprotein levels. The change of TG-AUC was significantly related to the changes of fasting TG, TC, LDL-C, and HDL-C levels after the treatment, which were related to the changes of fasting apoA-I and apoB levels significantly (P<0.001). Xuezhikang was shown to be beneficial in the treatment of reflecting postprandial triglyceridemia in CHD patients with normal and mildly elevated fasting TG levels.
