Trends in Alzheimer's disease and heart failure-related mortality among older American adults: Insights from the CDC WONDER database.
Article in American heart journal plus : cardiology research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Alzheimer's disease is one of the leading causes of death among the elderly in the United States with heart failure sharing similar risk factors. This study investigated trends and disparities in Alzheimer's disease mortality among older adults with heart failure from 1999 to 2020 in the United States. Methods: Making use of ICD-10 codes death certificate data from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research database was retrieved for patients aged ≥65 years between 1999 and 2020. Age-adjusted mortality rates (AAMRs), per 100,000 people, and Annual Percentage Change (APCs) with their respective 95 % Confidence Intervals (CI) were also calculated. Data was stratified by year, gender, race and geographical distribution. Results: Alzheimer's disease with coexisting heart failure was responsible for 192,459 deaths between 1999 and 2020. Overall the AAMR increased from 21.32 in 1999 to 24.56 in 2005 (APC: 1.9760*; 95 % CI: 0.6001 to 3.9507) after which a significant decrease to 16.52 by 2013 was observed (APC: -4.9301*; 95 % CI: -6.5209 to -4.0119). AAMRs decreased from this point forward reaching 22.21 in 2020 (APC: 4.1573*; 95 % CI: 3.0373 to 5.7232). Women had higher AAMRs than men (21.57 vs 18.41). Among racial groups, the Non-Hispanic (NH) White (21.62) population had the highest AAMRs followed by NH Black/African American (17.87), Hispanic/Latino (14.3) and NH Asian/Pacific Islander (8.96). Furthermore, AAMRs also varied by census region (West: 24.05; Midwest: 22.83; South: 21.1; Northeast: 13.38). Moreover, nonmetropolitan areas had higher AAMRs compared to metropolitan areas (27.23 vs 19.09). States in the top 90th percentile such as Kentucky, Oklahoma, Washington, North Dakota and Mississippi had AAMRs that were three times higher relative to states in the lower 10th percentile including Nevada, Florida, New York, District of Columbia and Hawaii. Conclusion: Alzheimer's disease mortality with associated heart failure has shown considerable variation in adults ≥65 years. AAMRs were highest in women, NH Whites, residents of the West and nonmetropolitan patient populations. Targeted interventions and a more holistic approach to patient management are essential in achieving favorable outcomes for vulnerable groups moving forward.
