Abstract

The relation of lipoprotein (a) [Lp(a)] and proprotein convertase substilisin/kexin type 9 (PCSK9) levels to coronary artery disease (CAD) has been well established in the general population, while little is known about the association between Lp(a) or PCSK9 and atherosclerotic lesions of different artery sites in patients with familial hypercholesterolemia (FH). One hundred and fifty-one patients with verified genotyped heterozygous FH (HeFH) were enrolled. There were available data regarding coronary angiography and carotid ultrasonography in 151 patients and femoral ultrasonography in 55 patients. Coronary and carotid severity was evaluated by Gensini score and Crouse score. PCSK9 and Lp(a) concentrations were determined by ELISA and immunoturbidimetry, respectively. Finally, the correlation of PCSK9 and Lp(a) with the presence and severity of CAD and peripheral artery disease (PAD) was assessed. The distributions of PCSK9 and Lp(a) were skewed and a close correlation between them in HeFH patients was found. PCSK9 levels were significantly higher in patients with coronary and carotid atherosclerotic lesions compared to their non-atherosclerotic groups, while no difference was found in femoral atherosclerotic lesions groups. ...Continue Reading
