Introduction. This study was done in order to evaluate the effect of serum
levels of total cholesterol, triglycerides, low-density lipoprotein-
cholesterol and high-density lipoprotein-cholesterol on 10-year coronary
heart disease risk distribution change. Material and Methods. This study
included 110 subjects of both genders (71 female and 39 male), aged 29 to 73,
treated at the Outpatient Department of Atherosclerosis Prevention, Centre
for Laboratory Medicine, Clinical Centre Vojvodina. The 10-year coronary
heart disease risk was estimated on first examination and after one-year
treatment by means of Framingham, PROCAM and SCORE coronary risk scores and
their modifications (Framingham Adult Treatment Panel III, Framingham Weibul,
PROCAM NS and PROCAM Cox Hazards). Age, gender, systolic and diastolic blood
pressure, smoking, positive family history and left ventricular hypertrophy
are risk factors involved in the estimation of coronary heart disease besides
lipid parameters. Results. There were no significant differences in
nutritional status, smoking habits, systolic and diastolic pressure, and no
development of diabetes mellitus or cardiovascular incidents during oneyear
follow. However, a significant reduction in cholesterol level (p<0.001),
triglycerides (p<0.001), low-density lipoprotein cholesterol (p<0.001) and an
increase in high-density lipoprotein cholesterol (p<0.02) was present
although therapeutic target values were not achieved. In addition, a
significant increase was observed in the category of low 10-year coronary
heart disease risk (Framingham- p<0.001; Framingham ATP III- p<0.001;
Framingham Weibul- p<0.001; PROCAM- p<0.05; PROCAM NSp< 0.05; PROCAM Cox
Hazards- p<0.001; SCORE- p<0.001) and a reduction in high-risk category
(Framingham- p<0.001; Framingham ATP III- p<0.005; Framingham Weibul-
p<0.005; PROCAM- p<0.001; PROCAM NS-p<0.001; PROCAM Cox Hazards- p<0.001;
SCORE- p<0.005) in comparison with the risk at the beginning of the study.
Conclusion. Our results show that the correction of lipid level after
one-year treatment leads to a significant redistribution of 10-year coronary
heart disease risk estimated by means of seven different coronary risk
scores. This should stimulate patients and doctors to persist in prevention
measures.
