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.

Background: The virtual rise of blood pressure resulted from stress, that is observed in subjects that are tested in medical centers, can be oftenly corrected by holter. This phenomenon causes such persons not to response to the common anti blood pressure treatments (2). Materials and methods: This descriptive study was conducted 2006-2007 at the heart clinic of Shohadaye–Ashayer hospital in Khorramabad during 2006-2007 to investigate the rate of stress induced H. T. N Coming to the clinics. The cases (N=200) were measured for their blood pressure with the standardized mercury devices. If the rate of their blood pressure was high, normal or mild to moderate HTN, they were measured at home with the Interface I. F 250 model of Holter monitoring for 24 hours. Then, using the t-test and SPSS, the rate of blood pressure in the both methods were compared and analyzed. Results: The comparison of blood pressure at the clinic and the 24-hours blood pressure measurement with the Holter monitoring showed that 35% of those who fell into two groups of mild and moderate hypertension at the clinic had a normal blood pressure, 70 subjects were suffering from high blood pressure, 20 cases were suffering from diabetes, 98 from hyperlipidemia while 76 patients were smokers, also 130 of them had familial hypertensive records. The statistical t-test demonstrated a significant difference between the average rate of systolic and diastolic blood pressure at the clinic and the 24-hour monitoring of blood pressure with the Holter (P<0. 001). Conclusion: In this study, the comparison of blood pressure valve at the clinic and the value of blood pressure during 24 hours using monitoring showed that 35% of the cases undergoing pharmacologic and non- pharmocologic treatments routinely and by the measurement of blood pressure at the clinic and / or at the doctor’s office did not need any treatment as their blood pressure were in the normal range (4, 5 ). Regarding the considerable difference between the blood pressure measured in the clinic and the 24-hour blood pressure at home, it is necessary to use the Holter monitoring for most of the patients suffering from the mild and/or moderate blood pressure (8).

Prevalence of obesity tends to increase in developing countries. Obesity as a health problem is very important because of its complications such as diabetes mellitus, hypertension, cardiovascular diseases and some cancers. Life style influences and affects on waist circumference and hip circumference. WHR is the most common index to determine description of fat in body. The purpose of this study was to estimate association of waist to hip ratio with blood pressure among people referred to urban health clinics in Arak city. Materials and Methods: This population based cross sectional study was conducted on 340 people over 18 referred to urban health clinics in Arak city. Data were collected using a questionnaire including demographic information, and were analyzed by SPSS software and Chi square test. In addition to waist circumference, hip circumference and blood pressure were measured by standard methods. Results: 32.6% and 67.4% of the subjects were male and female respectively. 16.2% of the males and 12. 2 of the females had hypertension. Waist to hip ratio had a direct relation with hypertension. Under surface of the ROC curves were calculated for each female 0.802 and male 0.815. The best cut off WHR had been calculated for prediction of hypertension for males was 0.895 and for females was 0.835. Conclusion: Between WHR, WC and HC, WHR is the best predictive index for hypertension in population of Arak city.

Background: Prevalence of End Stage Renal Disease (ESRD) is increasing in the world. Because of clinical importance of ESRD and absence of significant data, we studied the epidemiology of end stage renal failure in patients under hemodialysis in Lorestan province. Material and methods: This descriptive cross sectional study was carried out between January 2012 and January 2013 in dialysis centers of Lorestan university of medical sciences .Subject were selected by census method and data galhered using a questionnaire. At the end, collected data were analyzed by SPSS software, descriptive statistics and Chi-square test. Results: All the patients under hemodialysis were 318 cases, 182 out of them (57.2%) and 136(42.8%) were male and female respectively. The mean age of the subjects was 53.2± 16.4 years. The cause of renal failure in 38.1% of the patients were hypertension, diabetes (19.2%) and unknown factors (27.4%). As well as 5.97% of the patients infected by HCV, HBV or HIV . A significant statistical difference was observed between causes of chronic renal failure and different ages of the subjects (p=0.002). Conclusion: Augmentation of screening programs and especially, early referral of high risk subjects to nephrologists is recommended for prevention of end stage renal disease.
