African American elderly patients experienced a 6% higher mortality rate after cerebral infarction compared to white patients. Survival probabilities were notably lower for African Americans aged 65-74.

Area of Science:

  • Gerontology
  • Public Health
  • Neurology

Background:

  • Stroke is a leading cause of death and disability, particularly among the elderly.
  • Racial disparities in healthcare outcomes are a significant concern in the United States.

Purpose of the Study:

  • To compare post-stroke survival rates between African American and white patients aged 65 and older.
  • To identify potential racial differences in outcomes following cerebral infarction.

Main Methods:

  • Analysis of a national Medicare sample of patients hospitalized with cerebral infarction in 1991.
  • Follow-up of a biracial cohort for up to 3 years.
  • Utilized Cox regression modeling for covariate adjustment.

Main Results:

  • Included 47,045 patients (5,324 African Americans).
  • African American patients showed a 6% higher likelihood of death post-cerebral infarction compared to white patients.
  • African Americans aged 65-74 had significantly lower 3-year survival rates (15-20%) than their white counterparts.

Conclusions:

  • Evidence suggests racial disparities in elderly survival post-cerebral infarction.
  • Observed differences were less pronounced than those reported for stroke incidence and mortality.
  • Further research with detailed clinical data is recommended, especially for the 65-74 age group.
