Introduction: Cerebral artery diseases are the most prevalent neural disorder leading to serious diseases and death. Stroke is the third cause of death in the U.S. and is the most prevalent neurological disabling disease. This study aims to evaluate the influential factors of the duration of hospital stay in transient ischemic attack (TIA) or ischemic stroke   patients. Method of study This is re retrospective study. The population of study consists of all patients diagnosed as TIA or ischemic stroke who admitted in the neurology department of Urmia Imam Khomeini hospital from August, 2014 to August 2015. Data was collected from the cases’ records and analyzed using SPSS 22.\0 results A total number of 349 TIA and ischemic stroke cases was included in the study of whom, 322 (95.1%) and 17 (4.9%) cases were diagnosed and studied as ischemic stroke and TIA cases, respectively. In 258 cases (73.9%), the involved area was anterior circulation while in 91 cases (26.1%), it was posterior circulation. Considering relevant risk factors, hypertension with 212 cases (60.7%) was the most frequent risk factor followed by past medical history of stroke in 115 cases (33%), congestive heart failure in 113 cases (32.4%), diabetes mellitus in 86 cases (24.4%) and smoking in 72 cases (20.6%), respectively. Conclusion: According to our results, AF rhythm and anterior circulation involvement apparently affects the duration of hospital stay and increases it. This agrees with medicinal literature where AF has been introduced as a risk factor for cerebral embolic diseases and can be considered as a cause of TIA or ischemic stroke. 

Keywords: Duration of hospital stay, Ischemic brain stroke, TIA.
