New heart failure statistics show the condition moving in the wrong direction in the United States. The Heart Failure Society of America’s (HFSA) annual report, HF Stats 2026, published in the Journal of Cardiac Failure and highlighted in an HFSA announcement on October 5, 2026, finds that heart failure deaths have been rising since 2010 and that the condition is increasingly affecting adults well below retirement age. Here is what the report found, how strong the evidence is, and what readers can reasonably take away from it.
Key Takeaways
- About 7.7 million U.S. adults, roughly 3% of the adult population, are living with heart failure, according to the report.
- Heart failure contributed to 452,573 deaths in 2023, or 14.6% of all U.S. deaths.
- Age-adjusted heart failure mortality rose about 37% between 2010 and 2023, reversing earlier progress.
- Crude heart failure death rates more than doubled among adults aged 25 to 44 (up 121%) and nearly doubled among those aged 45 to 64 (up 96%) between 2001 and 2020.
- Nearly 1 in 4 Americans will develop heart failure in their lifetime, and many of its main risk factors, including high blood pressure and obesity, can be identified and managed early.
What Is Heart Failure?
Heart failure does not mean the heart has stopped. According to the CDC, it means the heart cannot pump enough blood and oxygen to support the body’s other organs. It is serious, but it can often be managed with medication, lifestyle changes and, for some patients, devices or surgery.
The CDC lists common symptoms as shortness of breath during everyday activities, trouble breathing when lying down, weight gain with swelling in the legs, ankles or feet, and general fatigue.
What the HF Stats 2026 Heart Failure Statistics Show
Prevalence and projections
The report estimates that 7.7 million U.S. adults have heart failure today and projects that number will grow to 8.7 million by 2030, 10.3 million by 2040 and 11.4 million by 2050 (HF Stats). Those projections reflect an aging population and the spread of cardiometabolic risk factors.
| Measure | HF Stats 2026 figure |
|---|---|
| Adults living with heart failure | ~7.7 million (about 3% of adults) |
| Deaths with heart failure as a contributing cause (2023) | 452,573 (14.6% of all deaths) |
| Deaths with heart failure as the underlying cause (2023) | 89,795 (age-adjusted rate 21.6 per 100,000) |
| Change in age-adjusted HF mortality, 2010–2023 | Up about 37% |
| Heart-failure-specific hospitalizations, adults (2023) | 1,272,855 |
| Hospitalizations with HF as primary or secondary diagnosis (2023) | 6,038,935 |
| Projected prevalence | 8.7M (2030) · 10.3M (2040) · 11.4M (2050) |
| Estimated direct and indirect costs | ~$46 billion (2020), projected $142 billion (2050) |

Younger adults are increasingly affected
One of the report’s most striking findings concerns working-age adults. Between 2001 and 2020, crude heart failure mortality rose 121% among adults aged 25 to 44 and 96% among those aged 45 to 64, according to the HFSA announcement. The report also points to rising hospitalization rates among people aged 65 and younger, and links the trend to obesity, high blood pressure and other cardiometabolic risk factors.
Many more people are “at risk” or in early stages
Heart failure is often described in stages. According to HF Stats, about one-third of U.S. adults meet criteria for Stage A (at risk, because of conditions such as hypertension, diabetes or obesity), and an additional 24% to 34% have Stage B, or “pre-heart failure,” in which structural heart changes are present before symptoms appear. These early stages are where prevention and early treatment are thought to have the most potential.
Gaps in care
The HFSA also highlighted underuse of guideline-directed medical therapy, persistent racial and ethnic disparities, and shortages in the advanced heart failure specialist workforce. Committee chair Dr. Eiran Z. Gorodeski said the burden of heart failure continues to move in the wrong direction despite therapeutic advances (HFSA).
How Strong Is the Evidence?
- Strengths: The report compiles national surveillance data, such as death certificates and hospital discharge records, which cover very large populations and are well suited to tracking trends over time.
- Limitations: These are descriptive statistics. They show that rates are changing but cannot by themselves prove why. Death certificate coding varies, and changes in diagnosis and recording practices can affect trends.
- Different sources, different numbers: The CDC’s own heart failure page cites about 6.7 million adults with the condition, while HF Stats 2026 estimates about 7.7 million. Figures differ depending on the survey years, definitions and methods used, so readers may see both numbers cited.
- Projections are estimates: Future case counts and costs depend on assumptions about population aging and risk-factor trends and should be treated as forecasts, not certainties.
Practical Takeaways
The report does not offer individual medical advice, and neither does this article. But public-health guidance from the CDC points to several widely recommended steps:
- Know your numbers. High blood pressure, diabetes and high cholesterol often have no symptoms. Regular checkups can detect them early.
- Address modifiable risk factors. The CDC lists smoking, unhealthy diet, physical inactivity, excess alcohol and obesity among the factors that raise risk.
- Don’t ignore symptoms. New shortness of breath, swelling in the legs or ankles, or unusual fatigue are worth discussing with a clinician promptly.
- Stay on prescribed treatment. People already diagnosed should talk with their care team before changing or stopping medications; the HFSA notes that proven therapies are underused.
Anyone with questions about their own heart health, risk factors or symptoms should consult a doctor or other qualified healthcare professional.
