Epidemiology of stroke in Shiraz, Iran
Background: Stroke is the main cause of physical disability and the second leading cause of death worldwide. Two-thirds of all strokes occur in the developing countries. Despite being preventable, stroke is increasingly becoming a major health issue in these countries. The aim of this study was to evaluate the epidemiology of stroke in Shiraz, Iran, one of the main referral centers in the southwestern part of Iran. Methods: A cross-sectional study was conducted on all stroke patients admitted to the Namazee Hospital, affiliated to Shiraz University of Medical Sciences, between August 2010 and January 2011. Patients' demographic data, atherosclerosis risk factors, type of stroke, drug history, outcomes, and neurological signs were recorded. Chi-square test, Kolmogorov-Smirnov test, t-test, and Mann-Whitney U-test were used to analyze the data. Results: A total of 305 patients with stroke, aged 27-97 years (mean ± SD = 68.33 ± 12.99), 269 patients (88.2%) had ischemic stroke (IS) and 36 (11.8%) had hemorrhagic stroke (HS). 133 patients (43.6%) were men and 172 (56.4%) were women. 11.4% of the patients with IS and 40.6% with HS died during hospitalization, causing 12.1% death in all stroke patients [Odds ratio (Or) = 5.34, 95% Confidence intervals (CI) = 2. 35-12.11]. Hypertension, ischemic heart disease, diabetes, and recurrent stroke were the most common risk factors.

Background: The Iranian population is aging rapidly, which causes huge medical concern for health care of this population. This trend will lead to an increase in stroke incidence in the future. The aim of this study was to investigate the epidemiologic patterns, risk factors, length of hospitalization, hospital discharge destination, and case fatality of patients with ischemic stroke from a city of Iran as well as analyses of interaction of these factors. Methods: A cross-sectional, multihospital-based study was performed on all consecutively discharged and diagnosed patients with ischemic stroke in the city of Qom, Iran, between March 2006 and September 2008.
Ten-year trend in stroke incidence and its subtypes in Isfahan, Iran during 2003-2013
Background: As there was no evidence of long-term studies on stroke trend, stroke subtypes and its relationships to stroke risk factors and demographic characteristics in Iran, we aimed to evaluate 10-year trend of stroke incidence and stroke subtypes in Isfahan, Iran. Methods: In a hospital-based retrospective study, 24186 cases with the first-ever stroke were analyzed. We assessed the incidence trend of annual stroke and its subtypes [ischemic stroke )IS(, subarachnoid hemorrhage (SAH), and intracranial hemorrhage )ICH(] during the years 2003 to 2013 by sex, and studied the association of demographic and major stroke risk factors with incidence and mortality rate of stroke. Results: The mean age was 69.46 ± 14.87 years, and 49.29% of patients were women. IS was the most frequent type among all the types of strokes (76.18%). Stroke and its subtypes had decreasing incidence trend during the study period, except for SAH that increased. In addition, stroke and its subtypes had decreasing mortality trend during the study period, except for SAH that did not change anymore. Stroke mortality and incidence rates were lower in urban inhabitants compared to residents of rural areas [odds ratio (OR) = 0.763, P < 0.001]. Conclusion: Despite the relatively high incidence of stroke over the study period, the incidence rate of stroke, especially ICH subtype, had a decreasing trend over the last decade in Isfahan. However, given the current young population in Iran, we can expect that the incidence of stroke would have an escalating trend in future.

Background Data about the risk factors of stroke are sparse in the Middle East populations. We aimed to determine the potential risk factors and their population attributable fraction (PAF) for stroke in an Iranian population. Methods A cohort Study consisted of 1089 men and 1289 women, with mean (SD) ages of 61.1(7.6) and 59.0(6.7) years, respectively. Cox regression was implemented to estimate the hazard ratio (HR) of each risk factor for stroke events in a stepwise method. We calculated a multivariate adjusted population attributable fraction (PAF) for any risk factors remained in the model. Results During 9.3 years of follow-up, 69 events of stroke occurred with incidence rates of 4.5 (95% CI: 3.3-6.0) and 2.5 (1.7-3.6) in 1000 person-years for men and women respectively. Among potential risk factors, only age ≥ 65 years (HR: 2.03, CI: 1.24-3.31), male gender (HR: 2.00, CI: 1.16-3.43), hypertension (HR: 3.03, CI: 1.76-5.22), diabetes mellitus (HR: 2.18, CI: 1.34-3.56), and chron...
Excessive Incidence of Stroke in Iran
Stroke, 2009
Background and Purpose— The epidemiology of stroke and its subtypes in the Middle East is unclear. Most previous studies have been performed in Western countries, and incidence rates are unlikely to apply in the Middle East. We aimed to determine the incidence of stroke in Mashhad, northeastern Iran. Methods— During a 12-month period (2006–2007), we prospectively ascertained all strokes occurring in a population of 450 229. Multiple overlapping sources were used to identify people with stroke. A large number of volunteers assisted in finding stroke patients not admitted to hospital. Potential cases were reviewed by a group of stroke experts before inclusion. Results— A total of 624 first-ever strokes occurred during the study period, 98.4% undergoing imaging. Despite a relatively low crude annual incidence rate of first-ever stroke FES (139; 95% CI, 128 to 149) per 100 000 residents, rates adjusted to the European population aged 45 to 84 years were higher than in most other countri...
A survey from Turkey and Iran on comparison of risk factors and etiology in ischemic stroke
Iranian Journal of Neurology, 2020
Although various advancements have been made to control incidence of stroke, the overall incidence, and the rate of morbidity of stroke, still increase in developing countries.1-3 In last years, the epidemiologic studies on ischemic stroke have been widely increased in Turkey and Iran.1-3 These two countries are located in similar geography with a similar historical background, though the environmental factors and lifestyle of general population in these two neighboring countries show peculiar differences. In this study, we aimed to make a comparison between data from Turkey and from Iran, in terms of etiologies and risk factors of ischemic stroke, to reveal region-related similarities or country-related differences. We reviewed the files of 2534 patients with ischemic stroke followed up for 15 years in our Cerebrovascular Outpatient Clinics in Faculty of Neurology, Istanbul University (Cerrahpasa), Istanbul, Turkey. Data collection in Iran was made from 2314 patients with ischemic ...

Background and purpose Performing a proper causative workup for ischemic stroke patients is essential as it guides the direction of primary and secondary preventions. We aim to investigate the etiological evaluation of these patients in university and nonuniversity hospitals. Method We enrolled subjects from the Persian Registry of Cardiovascular Disease–stroke. Stroke patients were categorized base on an etiological-based classification (Trial of Org 10172 in Acute Stroke Treatment or TOAST) into five groups. We also separated patients with ischemic stroke of undetermined etiology due to incomplete standard evaluation from ischemic stroke of undetermined etiology due to negative standard evaluation. The etiological subtypes and diagnostic evaluations were compared between the two hospital groups. Result Ischemic stroke of undetermined etiology was the most common subtype overall (43%). The prevalence of ischemic stroke of undetermined etiology (incomplete standard evaluation) was s...
