The follow-up research on the relationship between hyperhomocysteinemia and the recurrence rate of cerebral infarction after previous stroke / 中华神经科杂志

ABSTRACT

Objective To explore the possible effect of the plasma homocysteine level on the risk of recurrent cerebral infarction patients by follow-up research in hope for finding a new theoretical evidence for the therapy and the prophylaxis of cerebral infarction.Methods We determined the free plasma total homocysteine(tHcy)of 151 patients with acute cerebral infarction and 52 age-and gender-matched healthy controls by high-performance liquid chromatography,then we divided the patients into hyperhomocysteinemia (Hhcy)group and no hyperhomocysteinemia(Nhhcy)group according to the outcome.Within a 5-years follow-up period,we observed the recurrence of cerebral infarction in the 2 groups.Results There was no statistical deference in common information between Hhcy and Nhhcy group.But the recurrence rate of the Hhcy group,being 44.26%,was significantly higher than 12.22%of Nhhcy group(P
