Correlación entre la escala iScore y mortalidad en pacientes con evento cerebrovascular isquémico: Un estudio realizado en Guayaquil, Ecuador

Introduction: Cerebrovascular accident (CVD) is the second leading cause of disability and death worldwide. Several prognostic scores have been developed to predict functional outcomes after the event. The ischemic stroke predictive risk score (iScore) estimates the risk of death after hospitalization for an ischemic stroke. Objective: To describe the correlation between the iScore score and mortality in patients with ischemic stroke from Guayaquil, Ecuador. Methodology: Cross-sectional, non-experimental, prospective, quantitative study. It was carried out in the Neurology service of the Luis Vernaza Hospital, in the city of Guayaquil-Ecuador, during the period March-August 2023; Individuals who come to the emergency room with a confirmed diagnosis of ischemic stroke. Data was obtained from the electronic medical record regarding clinical-epidemiological variables and the iScore score was applied. The analysis was performed with SPSS Statistical Software version 24, applying statistical methods of frequency, percentage and association according to the proposed objectives. Results: A sample of 110 individuals was included. The average age of individuals with CVD was 70 years, with a predominance of males (52.7%). Among the most frequent comorbidities were arterial hypertension (72.7%), diabetes mellitus (37.3%) and atrial fibrillation (91%). The mortality rate was 127 per 1000 individuals. Statistical significance was found for those with elevated iScore (fifth quintile) with respect to mortality (p <0.001) (Table 1 and 2). Conclusions: This tool could be used as part of the initial assessment of mortality risk in patients with ischemic CVD.
