Long-term survival of patients with various types of cerebrovascular accident: data from the outpatient part of the REGION-M registry
Cardiovascular Therapy and Prevention(2023)
Abstract
Aim. To study the two-year survival rate of patients with various types of cerebrovascular accident according to the outpatient part of the REGION-M registry. Material and methods . The outpatient part of the REGION-M registry included 684 patients assigned to the City Polyclinic № 64, discharged from the F. I. Inozemtsev City Clinical Hospital (Moscow) in the period from January 1, 2012 to April 30, 2017 with a confirmed diagnosis of stroke or transient ischemic attack (TIA). Of these, 514 (75,1%) patients had an ischemic stroke, 52 (7,6%) — a hemorrhagic stroke, and 118 (17,2%) — a TIA. Results. The lowest two-year mortality (11%) was observed in patients who underwent TIA (p<0,001) compared with ischemic and hemorrhagic stroke. The relative risk of death for ischemic stroke was 2,0 (95% confidence interval (CI): 1,13-3,55) (p<0,05), and for hemorrhagic stroke — 2,51 (95% CI: 1, 22-5,15) (p<0,05) relative to patients with TIA. Mortality in patients with ischemic or hemorrhagic stroke did not differ significantly — 32,3 and 36,6% (p>0,05). The mean age of patients who underwent TIA was significantly less than the age of patients with hemorrhagic or ischemic stroke. With increasing age, the survival of patients significantly worsened in all types of strokes. In addition, multivariate analysis adjusted for age showed remained significant effect of the stroke type on survival as follows: the relative risk of death for ischemic and hemorrhagic stroke was 1,99 (95% CI: 1,12-3,53) (p<0,05) and 2,45 (95% CI: 1,19-5,02) (p<0,05). Conclusion. Mortality in patients with stroke was significantly lower after TIA than in any type of stroke and did not differ between subgroups of patients with ischemic and hemorrhagic stroke.
