Risk factors for coronary artery disease: a study comparing hypercholesterolaemia and hypertriglyceridaemia in angiographically characterized patients.
Fifty-two male patients undergoing coronary angiography were allocated to four groups each consisting of 13 subjects: group I had normal coronary arteries and patients in groups II-IV exhibited coronary artery disease. In group II, plasma cholesterol was below 250 mg dl-1 and triglycerides below 160 mg dl-1; in group III, cholesterol was above 270 mg dl-1 and triglycerides under 160 mg dl-1; and in group IV, cholesterol was under 270 mg dl-1 and triglycerides above 180 mg dl-1. The hypertriglyceridaemic group IV had the highest coronary score. In addition, it had lowest lipoprotein lipase activity, lowest HDL-cholesterol and lowest high-density lipoproteins-2 (HDL-2) levels, suggesting that this type of hypertriglyceridaemia is caused--at least in part--by lipoprotein lipase deficiency with impaired removal of the triglyceride-rich lipoproteins and increased catabolism of HDL-2. Our findings point towards a type of hypertriglyceridaemia strongly associated with coronary artery disease which should therefore be treated accordingly.
