ABSTRACT

Objective To investigate the relationship between hyperhomocysteinemia and cardiovascular structure in maintenance hemodialysis uremia.Methods One hundred and twenty-two patients with maintenance hemodialysis were involved in the study.The level of plasma total homocysteine(tHcy) was determined by fluorescence polarization immunoassay.The morphosis of left artrium was investigated by Doppler echocardiography.Echocardiographic parameters such as interventricular septum thickness(IVST),left ventricular posterior wall thickness(PWTH),left ventricular mass index(LVMI) and left ventricular ejection fraction(EF) were measured.Results The mean level of tHcy in the patients on hemodialysis was(23.52?11.91)?mol/L and the prevalence of hyperhomocysteinemia was 77.0%.The overall prevalence of left ventricular hypertrophy(LVH) was 42.6%.The level of tHcy in the group with LVH was higher than that of the group without LVH(31.75?10.43 vs 15.89?4.15?mol/L)(P
