Abstract

Background: Although the risk factors of ischemic strokes are well defined, there is slight information about their relations with the etiologies of ischemic strokes. This study investigated the distribution of ischemic stroke risk factors and their connections to diverse etiologies of cerebrovascular attack (CVA) and specific ischemic regions of brain. Methods: In this cross sectional study, we analyzed the data of patients with definite diagnosis of CVA, excluding hemorrhagic strokes, registered in Imam Hossein Medical Center in Tehran, Iran. The data were collected from entire archived medical records from March 2010 until September 2012, retrospectively. Results: Out of 1696 cases a total of 1011 subjects, 487 (48.2%) males and 524 (51.8%) females with mean age of 68.91±13.54 yr were included in the study. Patients suffering from atrial fibrillation (AF), valvular heart disease (VHD), and dilated cardiomyopathy were more prone to develop cardioembolic stroke. Those with diabetes mellitus (DM), carotid artery stenosis and dyslipidemia (DLP) had a higher prevalence of macroangiopathic stroke. Ischemic heart disease (IHD), AF, and VHD were associated with stroke in the brain territory supplied by middle cerebral artery (MCA) while DM and carotid artery stenosis were correspondent with posterior cerebral artery (PCA) stroke. Conclusion: The diagnosis of the weight of each risk factor of ischemic strokes on different etiologies and territories of ischemia can assist care providers for a more efficient prevention of strokes. The results of this study can also be a basis for further investigations to corroborate the pathophysiology of such relations. © 2015, Iranian Journal of Public Health. All rights Reserved.
