AIM: The purpose of the study was to investigate lipoprotein (a) (Lp(a)) levels and apolipoprotein (a) (apo(a)) phenotypes, and their relationship with a family history of coronary heart disease (CHD) in patients with essential hypertension (EH). METHODS: One hundred and eight newly diagnosed patients with mild to moderate EH and 159 controls were studied. Lp(a) levels were determined with an ELISA method. Apo(a) isoforms were identified by a capillary immunoblotting technique. RESULTS: Lp(a) levels and frequency distribution of apo(a) isoforms did not show significant differences between patients and controls. Lp(a) levels in hypertensives with a family history of CHD were significantly higher than in those without a family history of CHD (P < 0.01). Hypertensives with a family history of CHD showed significantly different frequencies of apo(a) isoforms to those without a family history of CHD (P < 0.05). In EH patients with a family history of CHD, apo(a) isoforms of low molecular weight (MW) had a higher prevalence (62.6%), while in hypertensives without a family history of CHD, apo(a) isoforms of high MW were prevalent (81.6%); the difference between the two subgroups was significant (P < 0.001). Multivariate analysis showed that both Lp(a) levels and apo(a) isoforms of low MW are significant variables in distinguishing between the subgroups. CONCLUSIONS: Lp(a) levels and apo(a) phenotypes do not differ between hypertensives and controls. High Lp(a) levels and apo(a) isoforms of low MW are strongly associated with a family history of CHD in hypertensives. The quantification of Lp(a) levels and the characterization of apo(a) phenotypes may be used for assessment of familial predisposition to CHD in hypertensives.
