[Risk factors of coronary artery disease in males during a 3 year follow up based on a cohort study in a selected region of Lublin]. / Czynniki ryzyka choroby wiencowej u mezczyzn w ciagu 3 lat obserwacji na podstawie badan kohortowych w wybranym regionie Lublina.

To assess changes in risk factors of coronary artery disease, examinations which had been performed in 1981 and 1982 were repeated in males aged 40-59, inhabitants of the district "Czechów" in Lublin. The study was based on Polish Experiment of Coronary Disease Multifactor Prevention assumptions 112 of 203 males investigated in 1981, 1982 underwent repeated examination (attendance rate - 55%). Statistical analysis was performed only in twice examined subjects. Significant increase of blood pressure, body weight, total serum cholesterol and uric acid concentration was stated in comparison with their respective initial values. Significant decrease of HDL-cholesterol and no changes in serum triglycerides concentration were observed. The only positive stated alteration was a lower percentage of tobacco smokers. Diagnosis of coronary artery disease remained unchanged despite of increased risk factors levels (increase of mean Rose's index score from 5 in initial examination to 6.5 in a control one). This high increase in risk factors occurrence allows an unfavourable prognosis for future incidence of coronary artery disease and also demands to undertake vigorous prevention.

[Prevalence of coronary disease risk factors in the male population 40-59 years of age from the housing complex "Czechów" in Lublin]. / Rozpowszechnienie czynników ryzyka choroby wiencowej w populacji mezczyzn w wieku 40-59 lat, z osiedla mieszkaniowego "Czechów" w Lublinie.

There was studied randomly selected approximately 10% sample of population of males aged 40-59 from the housing estate "Czechów" in Lublin. Authors assessed the level of coronary artery disease (CAD) basic risk factors as well as a percentage of persons with a high risk of developing CAD. The study was extended by determinations of plasma HDL--cholesterol, glucose and uric acid concentrations. Mean total cholesterol concentration (220.4 mg/dl) as well as the frequency of hipercholesterolemia occurrence (15.4%) were significantly higher in comparison with their values in male populations of Warsaw and Southern Poland. Mean systolic (134.2 mm Hg) and diastolic (87 mm Hg) blood pressures as well as frequency of hypertension occurrence (22.7%) were comparable with results of two, above mentioned, epidemiological studies. We stated the lower percentage of current tobacco smokers (52.2%). The overweight of 115% or more was stated in 22.2% of persons. Very high percentage of men of low physical activity was stated (51%). Higher level of respective risk factors reflected in individual score of CAD risk coefficient fixed on 5 points and being higher than in other studies of different Poland regions populations.
