Abstract

Objective
This study was done to evaluate the risk factors associated with recurrence after first-ever stroke.


Method
We retrospectively studied 256 first-ever stroke patients treated in Dong-Eui hospital from March 1997 to February 1998. Telephone or out-patient interviews were performed with these patients regarding stroke recurrence and treatment for hypertension and diabetes mellitus. These were divided into two groups, those with recurrence and those without. Evaluated risk factors for stroke recurrence were the following: history of diabetes mellitus, hypertension, heart disease, smoking, alcohol drinking, and transient ischemic attack; clinical findings at admission of hypertension, diabetes mellitus, hyperlipidemia, heart disease, type and location of stroke; treatment compliance for diabetes mellitus and hypertension after discharge.


Results
The recurrence rate after first-ever stroke was 12.9%. In univariate analysis, significant risk factors for stroke recurrence were history of smoking, clinical findings at admission of diabetes mellitus, atrial fibrillation, ischemic heart disease, and non-compliance with therapy for diabetes mellitus and hypertension after discharge (p<0.05). In multivariate analysis, significant risk factors for stroke recurrence were atrial fibrillation at admission (odds ratio=3.43) and non-compliance with therapy for hypertension after discharge (odds ratio=7.51)(p<0.05).


Conclusion
History of smoking, clinical findings at admission of diabetes mellitus, atrial fibrillation, ischemic heart disease, and non-compliance with therapy for diabetes mellitus and hypertension after discharge are considered to be important factors for recurrence of stroke. So treatment and education for those factors associated with stroke recurrence are needed during rehabilitation program.
