Comparison of the relation of triglyceride-rich lipoproteins and muscular artery compliance in healthy women versus healthy men.
To determine whether structural features or concentrations of plasma lipoproteins are predictive of arterial compliance in healthy women versus healthy men, cohorts of 111 men and 112 women with a wide range of 10-year risks for coronary artery disease were selected using assessments based on the Framingham Heart Study. Age ranges were restricted to 35 to 69 years for men and 45 to 79 years for women. Lipid-lowering drugs or any evidence of vascular disease was cause for exclusion. Fasting lipoprotein analysis and arterial compliance measurements in thigh and calf were completed in all patients. Plasma triglyceride levels were the most powerful predictor of compliance in women. Weaker but significant relations were observed between plasma non-high-density lipoprotein cholesterol, apolipoprotein-B, and apolipoprotein-CIII. In contrast, the only significant predictor of compliance in men was body weight. Thus, the major lipid predictors of arterial stiffness in women are concentrations of triglyceride-rich lipoproteins. These results are consistent with previous findings that triglyceride measurements are more strongly related to clinical vascular events in women than in men.
