title: Essential role of post-heparin lipoprotein lipase activity and of plasma testosterone in coronary artery disease.
abstract: 89 consecutive men for whom coronary angiography was requested because of suspected coronary artery disease were investigated with respect to plasma lipids, lipoproteins, post-heparin lipoprotein lipase (LPL), and some hormones that influence LPL. The severity of coronary-artery disease was expressed by the coronary score (CS). Coronary-artery disease correlated with total plasma cholesterol, low-density lipoproteins, high-density lipoprotein cholesterol (HDL-chol), and HDL2. In addition, there was a strong negative correlation (r = -0.479, p less than 0.001) between CS and LPL, as well as positive correlations between CS and plasma triglycerides (p less than 0.01) and very low-density lipoproteins (VLDL, p less than 0.01). The impairment of LPL activity correlated with increased VLDL and decreased HDL-chol. The extent of coronary-artery disease is thus strongly influenced by an LPL deficit. LPL activity correlated with plasma testosterone, and there is evidence that low plasma testosterone may be partly responsible for the low LPL and HDL-chol.
