[Total serum cholesterol and cholesterol lipoprotein fractions in random sample of Warsaw population]

The aim of the study was to evaluate the level of lipid risk factors in a random sample of Warsaw population aged 35-64 years, 764 men and 775 women, were screened within framework of the Pol-MONICA Warsaw Study. The lipids were determined by enzymatic methods in laboratory controlled by CDC Lipid Standardization Program in Atlanta. In the screened sample the observed levels of total cholesterol (5.76 +/- 1.01 and 5.68 +/- 1.03 mmol/l respectively in men and in women) and LDL cholesterol (3.67 +/- 0.90 and 3.56 +/- 0.94 mmol/l respectively) were rather high what can indicate on rather high coronary risk of Warsaw population. On the other hand the high mean level of HDL cholesterol (1.36 +/- 0.36 and 1.53 +/- 0.35 mmol/l respectively) and its subfractions HDL2 (0.24 in men and 0.39 mmol/l in women) as well as HDL3 (1.12 and 1.14 mmol/l respectively) observed in this sample can decrease this global risk. The compared mean level of cholesterol in lipoprotein fractions in the group of investigated persons with and without clinical manifestations of coronary heart disease confirm the observed in the other studies the higher mean levels of total cholesterol and LDL cholesterol in persons with coronary heart disease.
