title: [Clinical significance of plasma homocysteine in the coronary atherosclerosis patients]
abstract: OBJECTIVE: To investigate the clinical significance of plasma homocysteine Hcy in patients with coronary atherosclerosis. METHODS Plasma Hcy levels of 85 patients with coronary atherosclerosis and 68 normal controls were determined by fluorescence polarization immunoassay. RESULTS The mean levels of plasma Hcy were (9.31+/-3.80)&mgr;mol/L in normal controls and (13.39+/-6.06)&mgr;mol/L in patients with coronary atherosclerosis. That was (11.36+/-3.86)&mgr;mol/L in the patients with micro-pathological changes of coronary artery, (13.32+/-6.09)&mgr;mol/L with single-vessel disease,(13.39+/-4.92)&mgr;mol/L with double-vessel disease, and (18.23+/-8.98)&mgr;mol/L with three-vessel disease by coronary angiography. Statistically, the mean plasma Hcy concentrations in male and female patients was higher than that in the corresponding control subjects(13.77+/-6.68 compared with 10.50+/-4.07, 11.50+/-3.58 compared with 7.80+/-2.85 &mgr;mol/L,P<0.001 respectively). CONCLUSION The patients with coronary atherosclerosis present hyperhomocysteinemia is very important to determine plasma homocysteine for diagnosis and therapy in the patients with coronary heart disease.
