Abstract: Objective To investigate the related risk factors of the recurrence of cerebral infarction in elderly residents of Hebei Renqiu and to provide basis for its prevention and cure.Methods A cluster random sampling method was used for the age 60 to 70 years of Renqiu permanent residents as a screening object, including 5 010 cases, 459 cases of residents as the research object, They were screened in history of the first cerebral infarction,not losing after two years of follow-up. 53 cases of the cerebral infarction were recurrent. Prospective analysis was made on the related risk factors of the recurrence in cerebral infarction of the elderly community residents.Results Multivariate logistic regression analysis showed that LDL-C(OR=1.502,95%CI=1.023-2.207) and carotid artery plaque(OR=2.298,95%CI=1.085-4.867) were significantly related to the recurrence of cerebral infarction in Hebei Renqiu elderly residents(P<0.05).Conclusion LDL-C and carotid artery plaque are the primary risk factors of the recurrence of cerebral infarction in Hebei Renqiu elderly residents. Enough knowledge and active intervention on cerebral infarction have important significance in the effective prevention of recurrence.
