Impact of stroke clinical features on mortality risks according to hospital registry

The purpose of the paper is to study stroke clinical features and their impact on mortality risks according to Nalchik hospital registry. Materials and Methods. The work summarizes the data and carries out a statistical analysis of the clinical features of patients in the primary vascular department, City Clinical Hospital No. 1, and the Regional Vascular Center, Republican Clinical Hospital, Nalchik, the Kabardino-Balkarian Republic, in 2016-2017. Results. The statistical analysis of779 hospitalized patients showed that 696 patients (89.3 %) suffered an ischemic stroke; intracerebral hemorrhage occurred in 73 patients (9.4 %); subarachnoid hemorrhage was verified in 10 patients (1.3 %). There were 49.8 % of men and 50.2 % of women. The average age of men were 66.20±10.53 years of age; women were 75.00±10.53 years old. Patients aged 60-74 prevailed in the stroke morbidity structure (42.3 %). According to the TOAST classification, pathogenetic subtypes of ischemic stroke were distributed as follows: atherothrombotic - 53.7 % (n=374), cardioembolic -35.9 % (n=250), lacunar - 9.9 % (n=69), hemodynamic - 0.4 % (n=3). It was found out that in every second patient ischemic focus was localized in the middle cerebral artery basin (73.8 %). The dynamics of hospital mortality for ischemic stroke was 10.6 % in 2016 and 13.1 % in 2017; for intracerebral hemorrhage it was 32.1 % and 26.1 %, respectively; for subarachnoid hemorrhage - 37.5 % and 50.0 %, respectively. There were no statistical differences in the given indicators for different years. Conclusions. Research suggested that stroke was widespread among elderly and senile people. Such patients demonstrated moderate and severe stroke types (37.8 % and 59.4 %, respectively), which had a significant impact on mortality risks.
