Heart failure (HF) is a serious condition affecting nearly 6.7 million adults in the United States, with numbers expected to rise to over 8 million by 20301 2. Recent research estimates that approximately 15 million U.S. adults have a 10% or greater risk of developing heart failure within the next decade3 . This growing prevalence highlights the urgent need to understand the key risk factors and effective prevention strategies to reduce the burden of this disease4 .
“Heart failure is a growing epidemic affecting millions of individuals across all demographics. With a surge in mortality and continued underutilization of evidence-based therapies, it is imperative to prioritize improvements in the prevention, diagnosis, and treatment of heart failure.”

Heart Failure Risk Factors
Heart failure occurs when the heart cannot pump enough blood and oxygen to meet the body's needs, often due to structural or functional impairments5 1. The risk of developing HF increases significantly with age, especially in adults aged 70 years and older, making age the strongest risk factor6 3. However, several modifiable conditions also contribute substantially to HF risk.
Key modifiable risk factors include hypertension (high blood pressure), obesity, and diabetes. Hypertension affects nearly half of U.S. adults and leads to adverse cardiac remodeling that impairs heart function6 78. Obesity, defined as a body mass index (BMI) of 30 or higher, increases HF risk by causing structural changes in the heart6 7. Diabetes, particularly prevalent among Hispanic Americans, further elevates HF risk through metabolic and vascular effects9 7.
Despite advances in managing these risk factors, age-related changes in the heart continue to drive HF risk in older adults, even when traditional risk factors are controlled6 10. Additionally, a significant portion of elderly individuals at risk for HF do not exhibit typical modifiable risk factors, underscoring the complexity of HF development10 .
“The next step needed is clinical practice guidelines that provide frameworks for primary care physicians and other clinicians on how to use these calculators to customize patient care.”

The American Heart Association's PREVENT equations estimate 10-year HF risk using clinical data such as age, BMI, and kidney function. Using this tool, researchers identified 15 million U.S. adults with an elevated (≥10%) 10-year risk of HF11 34. Among those at elevated risk, over half had uncontrolled hypertension or obesity, highlighting these as critical targets for intervention3 .
| Risk Factor | Impact on HF Risk | Population Impacted |
|---|---|---|
| Age ≥70 | Major driver of HF incidence | Majority of high-risk adults |
| Hypertension | Causes cardiac remodeling | Nearly half of U.S. adults |
| Obesity (BMI ≥30) | Increases HF risk via structural changes | Over 55% of elevated risk group |
| Diabetes (HbA1c) | Contributes to HF, especially in Hispanics | Elevated in Hispanic Americans |
Additional risk factors for HF include coronary artery disease, valvular heart disease, cardiomyopathy, and other cardiac conditions5 12. Black Americans experience higher rates of HF incidence and prevalence compared to other racial groups, with about a 19% increased risk compared to white Americans2 13. These disparities emphasize the need for tailored prevention efforts.
Heart failure risk increases sharply with age, but modifiable factors like high blood pressure and obesity are key targets for prevention. Over half of adults at elevated heart failure risk have uncontrolled hypertension or obesity, making early intervention essential. 367
Heart Failure Prevention Strategies
Hypertension affects nearly half of U.S. adults and is a leading contributor to heart failure. Early detection and treatment of high blood pressure can halve the risk of heart failure, yet many remain unaware due to its silent nature. 78
Preventing heart failure primarily involves controlling modifiable risk factors such as hypertension, obesity, and diabetes14 . Effective management of high blood pressure can reduce the risk of developing HF by up to 50%, making blood pressure control a cornerstone of prevention7 8. However, hypertension is often asymptomatic, leading to underdiagnosis and undertreatment, which underscores the need for proactive screening and patient education8 .
| Prevention Strategy | Impact on Heart Failure Risk |
|---|---|
| Blood pressure control | Can reduce HF risk by up to 50% 78 |
| Weight management | Reduces structural heart changes6 7 |
| Diabetes management | Lowers metabolic stress on the heart9 |
| Lifestyle modification | Smoking cessation, healthy diet, physical activity6 1 |
| Addressing social determinants | Improves adherence and access to care15 |
“The patterns of people at risk for heart failure largely track with the same patterns seen in patients with heart failure. Age is the biggest driver, but age is not modifiable—high blood pressure and obesity are the risk factors we can address early.”
— Timothy Anderson, University of Pittsburgh11
Lifestyle interventions play a foundational role in HF prevention. These include smoking cessation, adopting a healthy diet low in saturated fats and sodium, and engaging in regular physical activity to maintain a healthy weight and improve cardiovascular health6 1. Addressing social determinants of health, such as family support and access to healthcare, is also critical for ensuring adherence to preventive measures and treatment plans15 .
The PREVENT risk calculator can help clinicians identify patients at elevated HF risk and guide personalized counseling on risk reduction strategies11 3. For example, patients with elevated risk may benefit from stronger recommendations for blood pressure reduction and weight loss3 . Despite the availability of risk prediction tools, further longitudinal validation is needed to improve their accuracy and clinical utility16 .
