title: Reversal of atherosclerotic obstructions by percutaneous transluminal angioplasty raises high-density lipoprotein cholesterol.
abstract: Variation of high-density lipoprotein cholesterol (HDL) levels in man show a strong inverse relationship to the incidence of atherosclerotic vascular disease. Conversely, effects of atherosclerosis and ischemia on lipoprotein metabolism are unclear. We investigated 41 patients, 10 women and 31 men, undergoing percutaneous transluminal angioplasty by measuring fasting lipoprotein cholesterol including high-density lipoprotein subfraction analysis before and one as well as 12 weeks after the procedure. Successful reopening of a haemodynamically significant iliac, femoral or popliteal obstruction was achieved in all patients. A highly significant (p < 0.001) increase of HDL cholesterol from 1.10 +/- 0.05 to 1.31 +/- 0.06 mmol/l was revealed 12 weeks later. This was due to a significant (p < 0.001) increase in HDL3 cholesterol by 26%, whereas HDL2 cholesterol did not change significantly. We conclude that HDL cholesterol levels increase after recanalization of a significant atherosclerotic obstruction which may be a direct effect of reperfusion or an indirect effect due to an increase in exercise tolerance.
