Key result

Hemorrhagic stroke mortality drops ~31% since 1999, but disparities remain for males and Black populations.

Why the study?

Hemorrhagic stroke remains a major cause of stroke-related mortality in the United States, but its demographic and geographic distribution remains incompletely described.

Population

830,251 hemorrhagic stroke deaths among adults in the United States

Comparison

Trends stratified by sex, race/ethnicity, region, urbanization, age group, and state

Design

Retrospective database analysis

Overview

Declines in hemorrhagic stroke mortality support prevention efforts; leaves open targeted research on persistent sex and racial disparities.

Key Points

  • To characterize trends in hemorrhagic stroke-related mortality in the U.S. from 1999 to 2023, focusing on disparities by demographic factors.
  • Analyzed CDC WONDER Multiple Cause-of-Death dataset from 1999 to 2023.
  • Identified hemorrhagic stroke deaths using ICD-10 codes I60–I62.
  • Calculated age-adjusted mortality rates per 100,000 using the U.S. 2000 standard population.
  • Utilized joinpoint regression to estimate average annual percent change.
  • 830,251 hemorrhagic stroke deaths recorded from 1999 to 2023.
  • National age-adjusted mortality rate declined from 17.96 in 1999 to 12.39 in 2023 (AAPC: −1.64).
  • Higher mortality in males (16.30) compared to females (14.50).
  • Black or African American individuals had the highest mortality rate (20.98).
  • Mortality was highest in the South (16.41) and among nonmetropolitan areas (16.51).

Structured PICO

Population
Adults in the United States with hemorrhagic stroke-related mortality recorded in the CDC WONDER Multiple Cause-of-Death dataset between 1999 and 2023 (n=830,251 deaths).

While overall hemorrhagic stroke mortality in the US declined significantly from 1999 to 2023, disproportionate burdens persist among males, Black populations, Southern residents, and individuals in nonmetropolitan areas.

Cite This Study

Sahil et al. (2026) studied this question. From 1999 to 2023, hemorrhagic stroke mortality in the U.S. declined from 17.96 to 12.39 per 100,000, but disparities remain, particularly for males and Black populations.
