Background: Brain ischemic disorders are common diseases of neural systems. One of the predisposing factors affect to the brain ischemia is systemic hypertension. The aim of this study was the determination of relation between blood pressure and spread of brain ischemia in CT scan in brain ischemia patients. Materials & Methods: In the first stage and on the basis of research group, we selected 33 males and 33 females at the age of 45 and more with the diagnosis of brain ischemia by chance. Then we collected the information of those patients about general information, post history of hypertension and cardiovascular diseases. Then, we recorded degree of systolic and diastolic blood pressure on the first day of bedridden time and recorded specifications of ischemia in CT Scan about numbers and extent of ischemia. In the final stage, we considered relations between systolic and diastolic pressures and extension of ischemia. Datas were analyzed by EPI6 software. Results: Those finding showed that about 63.3% of patients were in 65 to 74 years old. In 81.8% of them hypertension history was positive. It is also specified that 36.3% of patients had normal systolic blood pressure and 45.4% had normal diastolic blood hypertension, and 63.7% had several ischemia. The severity ischemia in 54 cases (81.8%) were above 2 cm2. It is specified that there was no significant relation between systolic blood pressure and extension of ischemia in CT scan, but there was a significant relation between diastolic blood pressure and extension of ischemia (P=0.03). Having the negative history of hypertension in conformity of two indexes was significant (0.03%). There is no significant relation about sex, but there was a significant relation between two indexes and age above 75 years old (P=0.04). Conclusion : It is demonstrated that blood pressure and hypertension without history have a major role in extension of ischemia and aged is important factor between relation of two indexes.
