Approximately 56 million people worldwide had heart failure in 2023, according to a comprehensive analysis of data from 204 countries. Gram Research analysis of this 2023 global study shows heart failure becomes more common with age and varies by region, with high blood pressure and blocked arteries causing most cases in older adults, while rheumatic disease and birth defects dominate in younger populations. The encouraging finding: most heart failure causes are preventable through controlling blood pressure, limiting alcohol, and avoiding tobacco.
According to Gram Research analysis of a major 2023 global study, approximately 56 million people worldwide are living with heart failure, a condition where the heart struggles to pump blood effectively. Researchers examined data from 204 countries over 33 years to understand how heart failure affects different populations. The study found that heart failure becomes more common as people age, and the causes vary dramatically by region. In some areas, high blood pressure and blocked arteries are the main culprits, while in others, rheumatic fever damage, alcohol use, and even a tropical disease called Chagas disease play bigger roles. The good news: most causes of heart failure can be prevented by controlling blood pressure, limiting alcohol, and quitting smoking.
Key Statistics
A 2023 global analysis of data from 204 countries found that approximately 56 million people worldwide had heart failure in 2023, with a range of 49.9 to 62.2 million cases when accounting for measurement uncertainty.
According to the 2023 Global Burden of Disease Study, high blood pressure and blocked arteries account for the majority of heart failure cases in older adults globally, while rheumatic heart disease and congenital heart defects are the leading causes in children and young adults.
The 2023 global analysis identified that alcohol-related heart failure peaks during middle adulthood, with eastern Europe, Australia, and the Caribbean showing particularly high burdens of alcohol-induced heart failure cases.
Research from the 2023 Global Burden of Disease Study shows that most heart failure etiologies are preventable through interventions targeting modifiable risk factors including elevated blood pressure, excessive alcohol consumption, and tobacco use.
The Quick Take
- What they studied: How many people worldwide have heart failure, what causes it in different regions, and how the problem has changed from 1990 to 2023.
- Who participated: This analysis included health data from all 204 countries and territories in the world, covering the entire global population over 33 years.
- Key finding: In 2023, approximately 56 million people globally had heart failure. The causes and severity vary significantly by location and age group, with some regions facing much higher burdens than others.
- What it means for you: Understanding your regional risk factors for heart failure matters. If you live in an area where high blood pressure or rheumatic disease is common, prevention becomes especially important. Most heart failure causes are preventable through lifestyle changes and medical management.
The Research Details
Researchers conducted a massive global analysis called the Global Burden of Disease Study, which combines information from hospitals, health surveys, and disease registries across all countries. They looked at data spanning from 1990 to 2023, tracking how heart failure has changed over three decades. This type of study, called a cross-sectional analysis, takes a snapshot of disease patterns at specific points in time and compares them across regions, ages, and sexes.
The team gathered information about heart failure cases and the underlying conditions that caused them. They used standardized methods to make sure data from different countries could be fairly compared, even though healthcare systems and record-keeping vary worldwide. They also calculated something called years lived with disability, which measures how much heart failure impacts people’s daily lives and quality of life.
This approach is powerful because it reveals not just how many people have heart failure, but also which causes matter most in different parts of the world. This helps doctors and public health officials focus prevention efforts where they’ll have the biggest impact.
Heart failure is one of the leading causes of disability and death worldwide, yet its burden is invisible in many places because it’s not tracked consistently. By creating a standardized global picture, this research helps governments and health organizations understand their true disease burden and allocate resources effectively. Different regions face different challenges: some need to focus on controlling high blood pressure, others on treating rheumatic fever, and still others on reducing alcohol-related heart damage.
This study is highly reliable because it used data from 204 countries and applied consistent methods across all regions. The researchers reported uncertainty ranges around their estimates, showing they were transparent about what they don’t know with certainty. However, the quality of underlying data varies by country, so estimates are more precise in countries with strong health systems and less precise in countries with limited health data collection.
What the Results Show
The global analysis found 56 million cases of heart failure in 2023, with a range of 49.9 to 62.2 million when accounting for uncertainty. This represents a substantial increase from 1990, reflecting both population growth and aging. Heart failure becomes increasingly common with age across all regions, meaning older adults carry the heaviest burden.
The causes of heart failure vary dramatically by geography and age. In older adults globally, the two most common causes are ischemic heart disease (blocked arteries) and hypertensive heart disease (damage from high blood pressure). However, this pattern shifts in younger populations. Children and young adults more commonly develop heart failure from congenital heart anomalies (birth defects) and rheumatic heart disease (scarring from untreated strep infections).
Regional patterns reveal important differences. South Asia, East Asia, Oceania, and sub-Saharan Africa face particularly high burdens of rheumatic heart disease. Eastern Europe, Australia, and the Caribbean show elevated rates of alcohol-related heart failure. Central and South America struggle with Chagas disease, a parasitic infection that damages the heart. These location-specific patterns show that prevention strategies must be tailored to each region’s unique challenges.
The study found that alcohol use as a cause of heart failure peaks during middle adulthood, suggesting that drinking patterns in younger years have long-term cardiac consequences. The proportion of heart failure cases caused by different factors shifts across the lifespan, with congenital and rheumatic causes dominating in youth and metabolic causes like high blood pressure becoming more prevalent with age. The research also highlighted that most heart failure etiologies are preventable, meaning public health interventions targeting modifiable risk factors could substantially reduce the global burden.
This 2023 analysis provides the most comprehensive global picture of heart failure burden to date, building on previous Global Burden of Disease studies from earlier years. The data confirms trends observed in smaller regional studies: heart failure is becoming more common as populations age, and preventable causes like high blood pressure and alcohol use remain major contributors. The detailed breakdown by region and etiology goes beyond previous analyses, offering new insights into location-specific disease patterns.
The study’s accuracy depends on the quality of health data available in each country. Wealthy nations with advanced healthcare systems have better disease tracking, so estimates for those regions are more reliable. Poorer countries with limited health infrastructure may have underestimated heart failure cases. Additionally, the study captures prevalence at specific points in time rather than tracking individual patients over time, so it cannot show how individual cases progress or respond to treatment. The underlying causes of heart failure are sometimes difficult to determine, especially in regions with limited diagnostic capabilities, which may affect the accuracy of etiology estimates.
The Bottom Line
If you have risk factors for heart failure (high blood pressure, diabetes, obesity, or heavy alcohol use), work with your doctor to control these conditions. This is supported by strong evidence. Monitor your blood pressure regularly and take medications as prescribed. Reduce sodium intake, limit alcohol consumption, and maintain a healthy weight. These steps can prevent or delay heart failure development. If you experience shortness of breath, unusual fatigue, or swelling in your legs, seek medical evaluation promptly.
Everyone should care about heart failure prevention, but especially people over 65, those with high blood pressure or diabetes, people with a family history of heart disease, and those living in regions where rheumatic fever or Chagas disease are common. Healthcare systems and public health officials should use this data to prioritize prevention programs targeting their region’s most common heart failure causes. People in developing countries should be aware that rheumatic fever prevention through prompt treatment of strep infections is critical.
Preventing heart failure is a long-term commitment. Controlling blood pressure and other risk factors over years and decades reduces your heart failure risk substantially. If you already have heart failure, proper treatment can stabilize your condition and improve quality of life within weeks to months. However, reversing existing heart damage takes longer and may not be fully possible, making prevention the most effective strategy.
