Ischemic stroke (IS) is the leading cause of disability, cognitive dysfunction and mortality worldwide. The aim of this study was to determine demographics, characteristics and intrahospital mortality among stroke patients in a tertiary university hospital during a five year period. A retrospective study was conducted enrolling 4753 IS patients admitted to Pauls Stradins clinical university hospital, Riga, Latvia from 2016 to 2020. The IS diagnosis was confirmed by head computed tomography (CT). The pathogenetic IS subtypes were determined using Causative Classification System for IS (CCSIS). Patient demographic, characteristic and clinical outcome data were collected. 56,24% (n=2673) of our study group were females. Mean age of the patients was 73,3 years. The two IS subtypes with the highest prevalence among our study population were atherothrombotic stroke (AS) and cardioembolic stroke (CS): AS – 27,44% (n=1394), CS – 47,38% (n=2252), respectively. Lacunar stroke (LS) was detected in 9,49% (n=451) patients. Other specified stroke (SS) types were noted in 2,42% (n=115) patients, meanwhile 13,28% (n=631) were cases of unspecified stroke (US). The intrahospital mortality rate among our study population was 11,99% (n=570) with the greatest rate observed among patients with CS: 16,79% (n=378). The intrahospital mortality rate among other IS subtypes were as follows: AS: 7,59% (n=99), LS: 0,67% (n=3), SS: 8,70% (n=10), US: 12,68% (n=80), respectively. IS is a common entity with an immense public health importance. In our study population, IS was identified mostly among elderly patients with a slight female predominance. The most commonly observed IS subtype with the greatest mortality rate was CS. LS was the rarest IS subtype and was presented with the lowest intrahospital mortality rate.
