title: [Electrophoresis in the quantitative determination of cholesterol in lipoprotein fractions and its clinical application].
abstract: OBJECTIVE
  To evaluate the clinical application of the electrophoresis method for measuring serum cholesterol in lipoproteins and to study the characteristics of lipoprotein fractions in patients with the acute coronary syndrome.
  
  
  METHODS
  Cholesterol in lipoprotein fractions in fasting serum was measured by electrophoresis in 26 patients with the acute coronary syndrome and 20 patients with stable angina pectoris. The results were compared to cholesterol in lipoproteins measured with the regular method.
  
  
  RESULTS
  There was a good correlation between the methods with coefficients of 0.922, 0.909, and 0.899 for LDL-C, HDL-C and VLDL-C, respectively. The serum levels of TG and VLDL-C in the patients with the acute coronary syndrome were significantly higher than those with stable angina pectoris [(0.47 +/- 0.33) mmol.L-1 vs. (0.29 +/- 0.19) mmol.L-1, P < 0.01, (1.82 +/- 0.70) mmol.L-1 vs. (1.31 +/- 0.48) mmol.L-1, P < 0.01].
  
  
  CONCLUSIONS
  The electrophoresis method for quantifying cholesterol in lipoprotein fractions is well correlated with the regular method. The serum levels of VLDL-C and TG in patients with the acute conronary syndrome are higher than those with stable angina.
