title: [Extent of coronary sclerosis in relation to lipoprotein lipase activity and plasma triglyceride levels].
abstract: Coronary artery disease (CAD) is closely connected with an increased concentration of cholesterol and a decreased concentration of high-density lipoprotein cholesterol (HDL-chol) in human plasma. No general agreement exists about the atherogenic potential of increased plasma triglycerides. Although both a negative correlation between plasma triglycerides and post heparin lipoprotein lipase (LPL) and a positive correlation between the plasma concentration of HDL-chol and LPL-activity are well documented, only a few studies have investigated the relationship between CAD and LPL. Therefore, 109 male patients with angiographically assessed CAD were investigated with respect to plasma lipids, post heparin LPL, and plasma testosterone and estradiol, which are both known to influence LPL-activity. Many well known results were confirmed. The extent of CAD, assessed by coronary angiography as coronary score (CS), was significantly positively correlated to plasma cholesterol, plasma triglycerides, plasma phospholipids, plasma low-density lipoprotein cholesterol (LDL-chol) and age. CS was significantly negatively correlated to LPL-activity and to the plasma concentration of HDL-chol. LPL itself was significantly negatively correlated to plasma cholesterol, plasma triglycerides and phospholipids, and significantly positively correlated to HDL-chol and plasma testosterone. The most surprising result of this study was the significant correlation between CS and LPL (r = -0.4624; p less than 0.001), a correlation which could explain the increased plasma triglycerides and decreased plasma HDL-chol.
