title: Serum Lp(a) lipoprotein levels in patients with atherosclerotic occlusive disease of the lower extremities.
abstract: OBJECTIVE
  To evaluate the association between Lp(a) lipoprotein levels, other serum lipids and the presence of lower limb atherosclerotic occlusive disease.
  
  
  METHODS
  Angiographic findings in 36 patients were related to serum Lp(a). Total cholesterol, triglycerides, LDL-cholesterol, HDL-cholesterol and Lp(a) levels were compared with those of 73 age- and sex-matched healthy controls.
  
  
  RESULTS
  Atheromatous lesions were localised in the femoropopliteal ( approximately 60%) and aortoiliac ( approximately 40%) segments. The number of stenosed arteries was > or =2 and the range of stenosis severity was between 40% and 100%. There was a significant increase in serum Lp(a) (p= 0.000001) and a decrease in serum HDL (p= 0.000009) levels in patients compared to controls. No difference was observed in total cholesterol, LDL-cholesterol or triglyceride. However, the ratio of total cholesterol/HDL-cholesterol was significantly higher (p= 0.005) in patients.
  
  
  CONCLUSIONS
  A dyslipidaemic serum profile, characterised by increased Lp(a) levels and decreased HDL-cholesterol levels, is associated with atherosclerotic occlusive disease of the lower extremities.
