Plasma lipid and lipoprotein concentrations in Chinese males with coronary artery disease, with and without hypertension.
Plasma lipid and lipoprotein concentrations were determined in 125 Chinese males with a medical history and electrocardiographic abnormalities consistent with the diagnosis of coronary artery disease (CAD). All subjects underwent coronary arteriography, and patients were divided into 3 groups based upon the results of the coronary arteriograms: 1) patients with a negative angiogram (CAD-, n = 30), without hypertension; 2) patients with a positive angiogram, without hypertension (CAD+, n = 70); and 3) patients with a positive angiogram, who had hypertension (CAD + HT, n = 25). Mean fasting plasma lipid and lipoprotein concentrations of these 3 groups of patients were compared to values in age and weight-matched groups of normal individuals (n = 80) and untreated patients with hypertension and no evidence of CAD (HT, n = 20). The results indicated that total plasma triglyceride, cholesterol, and LDL-cholesterol levels were significantly higher (P less than 0.001) than normal in patients with CAD+ and CAD + HT, whereas only plasma cholesterol levels were higher than normal in patients with HT. Although patients with CAD- had values intermediate between normal and CAD, the differences were not statistically significant. In addition, the ratio of LDL to HDL-cholesterol was significantly increased (P less than 0.05-0.001) above normal in patients with CAD+, CAD + HT, and HT. As before, the values in patients with CAD- were intermediate. These data document the presence of multiple abnormalities of lipid and lipoprotein concentration in patients with angiographic evidence of CAD, whether or not they were hypertensive. Furthermore, abnormalities in lipid and lipoprotein metabolism were seen in patients with hypertension alone.
