Stroke is the second leading cause of death worldwide. Changes in survival rate could be due to changes in mortality rates and changes in the levels of risk factors. This study aimed to determine the most important risk factors affecting survival of patients with stroke in Shahroud.
In this retrospective cohort study, 380 patients with ischemic stroke were followed-up for one year after the stroke. Information on patients was collected through hospital records, interview and in case of death through interviewing with the deceased family. Then, the data were analyzed using the Kaplan-Meier method and Cox semi parametric model at the significance level of 0.05 with SPSS21 and Stata12.
The mean age of patients was 63±6.03. Among the patients 237 (62.4%) were men.Using Kaplan-Meier method, survival rates of one month, six months and one year were respectively, with 98.7, 80.3 and 78.4. Age, number of hospitalizations,(GCS) level of consciousness, hypertension, diabetes, HLP, IHD, HDL, FBS, and smoking show significant correlations with survival (p Since the risk increases during the months following the stroke, it is necessary to follow up patients so that they visit their doctors based on appointments.
