Five-year survival in ischemic stroke patients

Abstract

Introduction: Stroke is the first cause of permanent disability in adults, second cause of dementia and also of death in the world. Objective: Obtain an estimate of 5 years survival in patients who suffered an ischemic stroke. Methods: Observational, descriptive and longitudinal study in patients who suffered an ischemic stroke during 2017 and were followed evolutionarily for 5 years. Summary and dispersion measures were used depending on the nature of the variables and the Kaplan-Meier estimator to estimate survival. Results: At 5 years survival was 73.9%, with a mean of approximately 4 years. The cumulative proportions per year of follow-up were 84.1% (at 1 year), 81.4% (2nd year), 78.2% (3rd year), 75.7% (4th year). The survival graph corresponds to a type III curve. The factors that seem to be related to survival were: Age, level of consciousness, magnitude of the neurological deficit (NIHSS scale), stroke subtype, leukocyte value, C-reactive protein, blood glucose and leucoglycemic index. Conclusions: The survival of patients with ischemic stroke at 5 years is higher than that reported by some authors worldwide, although it can be improved if metabolic control is achieved in the acute phase.
