LIPOPROTEIN(A) MEANING AS AN ADDITIONAL MARKER OF CARDIOVASCULAR RISK IN PATIENTS WITH FAMILIAL HYPERCHOLESTEROLEMIA

Abstract

Aim. To analyze the relation of Lp(a) and atherosclerosis development in familial hypercholesterolemia (FHCE).

Material and methods. Totally, 81 patient with definite FHCE studied, mean age 39,1±0,4 y. o. The participants were selected to two groups: first — with increased level of Lp(a) >0,3 g/L (n=34); mean age — 44,5±0,3; second — with normal Lp(a) <0,3 g/L (n=47, 58,1%); mean age — 37,5±0,3 y. o.

Results. Mean level of Lp(a) in various age persons did not differ significantly. In both subgroups in about a half of all participants there was arterial hypertension (AH) revealed (50,8% and 42,6%, respectively), obesity was diagnosed in one third of both groups, number of smokers was higher in higher Lp(а) group (11,8% and 8,5%). IHD had 25,9% of participants. Revalence of IHD in IHD group was 44, 4%, in non-smoker group — 25,8% (RR 1,72 (0,75; 3,99)), acute myocardial infarction prevalence (MI) in smoking subgroup was — 44,6% versus 13,5% (RR 3,26 (1,26; 8,43)). Among lipid profile parameters LDL level was definitive for IHD development (p=0,012). Presence of obesity increased MI risk 2,54 times in FHCE (OR 2,4 (1,05; 5,63)). With increase of Lp(a) IHD was diagnosed more commonly: 32,4% versus 19%, non-significant (p=0,47). Prevalence of MI in the first group was higher than in the second: 8 (23,5%) and 4 (8,5%), respectively, (OR 3,3 (1,1; 9,8), р=0,03).

Conclusion. In FHCE, the risk of IHD was influenced by traditional RF (smoking, obesity, LDL level).
