RESUMO
Objective To determine the association between homocysteine and severity of large cerebral artery atherosclerosis.Methods Total 152 ischemic stroke patients were evaluated using transcranial Doppler(TCD),magnetic resonance angiography(MRA) or digital substraction angiography(DSA).Severity of cerebral artery atherosclerosis was scaled by number of stenosed or occluded artery.Results There were 83 patients in low level homocysteine group with mean Hcy level(15.31?3.08)?mol/L,while 69 patients in high level homocysteine group with mean Hcy(34.47?21.38)?mol/L.Number of abnormal intra-and extra-artery was 1.86?1.51 and 1.52?1.46 respectively.No significant difference was demonstrated in the number of abnormal artery between two groups.No correlation was noted between Hcy and number of abnormal artery.Conclusion There is no relationship between high homocysteine and severity of large cerebral artery atherosclerosis in ischemic stroke patients.Homocysteine might be the marker of the disease.
