Background & Objectives:Stroke is the third most common cause of death after heart disease &cancer and the most common disabling neurological disorder. The incidence increases with age, and is somewhat higher in male than in female. The main risk factor of stroke is hypertension. In last years incidence of stroke has decreased due to improvement of hypertension treatment but due to occurrence of cerebrovascular accident with normal blood pressure, in many patients with stroke. This study aimed to evaluate the frequency of mortality and morbidity in stroke patients with hypertension & normal blood pressure.

Methods:This descriptive retrospective study, evaluated 8121 patients with stroke who were admitted at hospital (1997-2006). The inclusion and exclusion criteria were defined. Data was gathered through check list and analyzed by SPSS soft ware 10 edition and the results were compared with each other.

Results: The total mortality and morbidity rate of stroke was 13.59% who 19.3% of patients with high mean blood pressure and 10.2% of patients with normal mean blood pressure were expired due to stroke. The mortality based on age in two groups was similar and more frequent in 65 to 74 year olds. The rate of mortality and morbidity in patients with high mean blood pressure in male and female were similar but in normal mean blood pressure cases were more frequent in male than in female. Hemorrhagic stroke was the most common type of stroke in hypertensive patients (59.55%) and in normotensive patients, ischemic stroke was more frequent (37.7%). The duration from admission to death was similar in two groups and the death was highest within 72 hrs after admission.

Conclusion:Since mortality and morbidity according to age had no significant difference in both groups. It seems other risk factors are effective in evaluating cerebrovascular accidents (prognosis).

Keywords: cerebrovascular accident, mortality and morbidity of stroke, hypertension, normal blood pressure
