Abstract WP102: Trends and Disparities in Heart Failure and Stroke-Related Deaths Among Older Adults in the United States: A CDC WONDER Analysis (1999-2023)

Background: Stroke associated with heart failure (HF) remains a significant cause of mortality in the older U.S. adults. We examined long-term trends in age adjusted mortality rates (AAMRs) from 1999 to 2023 stratified by demographic and geographic factors. Hypothesis: We hypothesize that mortality from stroke associated with heart failure in older U.S. adults declined substantially from 1999 to 2023, but recent rebounds emerged after 2018. Methods: Mortality data of adults ≥65 years with stroke associated with HF were extracted from CDC wonder database. AAMRs (per 100,000) were calculated using U.S. standard population weights and ICD-10 codes for stroke (I60–I64) and heart failure (I50). Trends analyzed using join point regression to estimate average annual percent change (AAPC) with 95% confidence intervals (CIs). A p-value of
