Abstract DP240: Comparative Analysis of Mortality Due to Intracerebral Hemorrhage versus Cerebral Infarction in Hypertensive Adults Aged ≥65 Years in the United States (1999–2020)

Introduction: Intracerebral hemorrhage (IH) and cerebral infarction (CI) are leading causes of stroke mortality in older adults, with hypertension as a principal modifiable risk factor. Although stroke mortality has declined overall, long-term comparisons between these subtypes in hypertensive elderly populations remain insufficient. Methods: CDC WONDER mortality data (1999–2020) were analyzed for decedents aged ≥65 years with hypertension (I10) as the underlying cause of death and IH (I61) or CI (I63) as contributing causes. Age-adjusted mortality rates (AAMRs) per 100,000 were standardized to the 2000 U.S. population. Trends were assessed using Joinpoint regression, reporting annual percent change (APC) with 95% confidence intervals, stratified by sex, race/ethnicity, census region, and urbanization. Results: We identified 101,452 IH-related and 48,670 CI-related deaths. IH mortality declined steadily (AAMR 11.08; APC –2.10%, p
