Clinical role of increased apolipoprotein B levels in coronary heart disease
Aim. To investigate clinical role of serum apolipoprotein B (apo B) levels in coronary heart disease (CHD). Material and methods. The study included 122 patients (mean age 49,7±7,1 years) with possible CHD diagnosis, who underwent clinical and instrumental examination. The diagnosis was confirmed by anamnesis data, stress tests and coronary angiography results. Apo B concentration was measured by immune8enzyme method. Results. In women, sensitivity of elevated apo B levels was lower than that of hypercholesterolemia (HCH); nevertheless, specificity of both parameters was similar. In men, HCH was more sensitive and specific than increased apo B levels. Conclusion. Substantial differences in sensitivity and specificity of increased apo B levels were observed in women and men with possible CHD, as well as in various groups of men.
