Insights
Predictors like older age, female gender, and stroke severity indicate a poor prognosis for first-ever stroke (FES) patients in middle-income countries. Early interventions are crucial for improving outcomes.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Limited data exists on stroke outcome predictors in middle-income countries.
- Understanding these predictors is vital for targeted interventions.
Purpose of the Study:
- To identify predictors of poor outcomes within 3 months and 1 year post-first-ever stroke (FES).
- To analyze these predictors in a population-based study in Brazil.
Main Methods:
- Prospective investigation of FES patients in Matão, Brazil (2015-2020).
- Poor outcome defined as modified Rankin scale (mRS) score 3-6 at 3 months and 1 year.
- Logistic regression analysis to identify associated predictors.
Main Results:
- 50.4% and 47.1% of patients had poor outcomes at 3 months and 1 year, respectively.
- Older age, female gender, hemiplegia, aphasia, subarachnoid hemorrhage, and comorbidities were significant predictors.
- Analysis included 378 patients from an initial 783.
Conclusions:
- Both non-modifiable and modifiable predictors impact FES prognosis in middle-income settings.
- Interventions targeting high-risk populations and improving acute stroke care are necessary.
Background:
The data on predictors of poor outcomes for stroke patients in middle-income countries are lacking.
Objective:
To identify in the acute phase after a first-ever stroke (FES) predictors of a poor outcome within 3 months and 1 year in a population-based study in the town of Matão, state of São Paulo, Brazil.
Methods:
We prospectively investigated the characteristics of patients with FES in Matão, from a prospective study, in a population-based stroke registry, from 2015 to 2020. Poor outcome was defined as a modified Rankin scale (mRS) score of 3 to 6, assessed at 3 months and 1 year of follow-up. The association between predictors and poor outcome was analyzed by logistic regression analysis.
Results:
Of the 783 patients, the final sample consisted of 378 subjects for analysis. The mean age was 69.2(± 14.3) years, and 43.1% of patients were female. At 3 months and 1 year after a FES, 50.4% and 47.1% of stroke patients were classified as poor prognosis, respectively. Older age, female gender, hemiplegia, aphasia, subarachnoid hemorrhage, and comorbidities present in the acute phase were the predictors associated with a poor outcome.
Conclusion:
Non-modified and potentially modified predictors increase the risk of a poor FES prognosis in a population-based study from a middle-income country. Interventions focusing on these target populations and improving access to prevention and stroke management in the acute phase are necessary.
