BACKGROUND: Prior authorizations could hinder the filling of life-saving heart failure (HF) medications, such as angiotensin receptor neprilysin inhibitors (ARNIs) and sodium glucose cotransporter 2 inhibitors (SGLT2is).

OBJECTIVES: The aim of the study was to determine whether prior authorizations were associated with delayed or decreased filling for ARNI and SGLT2i.

METHODS: This was a retrospective cohort study using electronic health record, pharmacy fill, and neighborhood-level data from a large, academic health system. We included patients with HF and a new prescription for ARNI or SGLT2i between April 1, 2021, and April 30, 2023, and assessed for presence of prior authorization requirement. Outcomes included days to first fill and never filling the prescription. Analyses were conducted using inverse probability weighting methods.

RESULTS: Among 2,183 patients, 12.2% (152/1,243) and 14.3% (165/1,150) had a prior authorization requirement for ARNI or SGLT2i, respectively. Patients requiring prior authorization tended to be younger, identify as non-Hispanic Black or Hispanic, have non-Medicare insurance, and have fewer comorbidities. In weighted models, patients requiring prior authorization took 3.03 (95% CI: 2.16-4.25) times longer to fill ARNI, 6.75 (95% CI: 4.44-10.3) times longer to fill SGLT2i, and were 2.23 (95% CI: 1.37-3.65) times more likely to never fill SGLT2i prescriptions (all P < 0.001).

CONCLUSIONS: Prior authorization requirements were more common for patients identifying as Black or Hispanic and were associated with decreased and delayed filling of ARNI and SGLT2i. Our findings highlight an important barrier to mortality-reducing, guideline-recommended medications for HF.

BACKGROUND: The American Heart Association annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and cardiovascular-kidney-metabolic syndrome) that contribute to cardiovascular health. The 2026 Heart Disease and Stroke Statistics Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS: The American Heart Association, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistics Update with review of published literature through the year before writing. The 2026 Statistics Update is the product of a full year's worth of effort in 2025 by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes a new chapter on cardiovascular-kidney-metabolic syndrome, as well as an expanded chapter on tobacco and nicotine use and exposure.

RESULTS: Each of the chapters in the Statistics Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS: The Statistics Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

OBJECTIVE: Identifying social and economic factors associated with initiation of semaglutide or tirzepatide may inform strategies to support equitable uptake.

RESEARCH DESIGN AND METHODS: A cross-sectional study was conducted using 100% of Medicare claims of patients ≥65 years with type 2 diabetes mellitus (T2DM). The outcome was initiation of semaglutide or tirzepatide. We calculated adjusted odds ratios (aORs) for each exposure (self-reported race and ethnicity, dual enrollment in Medicare and Medicaid, rurality, and social vulnerability index), accounting for demographic and clinical characteristics.

RESULTS: Among 13,922,387 patients with T2DM, 673,776 (4.8%) initiated semaglutide or tirzepatide in 2023. Minoritized racial and ethnic identity (e.g., non-Hispanic Black compared with White; aOR 0.72; 95% CI 0.71-0.72), dual enrollment (aOR 0.90; 0.89-0.91), and residence in the most versus least vulnerable socially vulnerable neighborhoods (aOR 0.93; 0.92-0.93) were associated with lower initiation.

CONCLUSIONS: Minoritized racial and ethnic identity and adverse socioeconomic factors were associated with lower odds of initiation among Medicare beneficiaries with T2DM.
