CHARACTERISTICS OF THE PATIENTS WITH ACUTE ISCHEMIC STROKE

Abstract

Stroke is defined by the World Health Organization as "rapidly developing clinical signs of focal (sometimes global) brain dysfunction lasting more than 24 hours or leading to death for no apparent reason other than vascular origin." Тhe aim of the present study is to characterize the patients with stroke coded according to the International Classification of Diseases as I63.3 and I63.4 who have passed through the Second Clinic of Nervous Diseases of the University Hospital "St. Marina "- Varna for the period from 01.2020 to 07.2021. Material and methods: A retrospective and prospective analysis of 716 stroke patients who passed through the Second Clinic of Nervous Diseases of the University Hospital "St. Marina ”- Varna for the period from 2020 to August 2021 with an average age of 72.5 years ± 11.4 years (20-96 years), of which 52.5% are women. Results were processed with SPSS v. 20.0, using variance, variation, comparison and correlation analyzes. The significance level was p <0.05 with a confidence interval of 95%. Results and discussion: For the study period, 716 patients with stroke were analyzed and followed with a mean age of 72.5 years ± 11.4 years, with a minimum of 20 years and a maximum of 96 years. No gender difference was observed, but a slight predominance of women (52.5% women and 47.5% men, respectively). There was a significant difference in terms of age and gender, with stroke in women occurring significantly later (p <0.001). More than 2/3 (68.0%) of patients have a cerebral infarction caused by cerebral artery thrombosis, and 32.0% have a cerebral infarction caused by cerebral artery embolism. It was found that males carry 1.58 times higher risk of developing cerebral infarction caused by cerebral artery thrombosis (OR = 1.58 (1.15-2.18) p = 0.003). Conclusions: Ischemic stroke remains the most common type of stroke in the world.
