Expanding the treatment of high blood pressure to reach 80% of eligible adults in 20 upper- and lower-middle-income countries could prevent an estimated 518,476 cardiovascular deaths annually, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2026. The modeling analysis, which examined health data from countries with the highest numbers of non-communicable disease deaths, found that hypertension control would save more lives than any other preventive service studied, including statin therapy, glucose control, and cancer screenings.
High blood pressure is the most prevalent and modifiable risk factor for cardiovascular disease, yet only about one in five adults with hypertension in the 20 countries studied had their blood pressure controlled below 140/90 mm Hg. The American Heart Association's 2025 Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults recommends a treatment goal of less than 130/80 mm Hg for most adults. "This modeling analysis offers important information on the potential global impact of high blood pressure and, importantly, the opportunity to, with treatment, reduce the number of deaths due to high blood pressure-related conditions," said Daniel W. Jones, M.D., FAHA, chair of the guideline writing committee and past president of the American Heart Association.
The study estimated that increasing statin use for high cholesterol could prevent 340,682 deaths, while better glucose control in people with diabetes could prevent 309,520 deaths. Colon cancer screening was the most effective cancer screening, potentially avoiding 206,767 deaths each year. These findings highlight that while all preventive services offer substantial benefits, blood pressure management yields the greatest return in lives saved, particularly in lower-middle-income countries where 223,655 deaths could be prevented annually.
"While there were substantial gaps in the use of preventive healthcare services for these conditions in all countries, lower-middle-income countries had large opportunities for improvement, with low rates of hypertension control and high cholesterol management and minimal use of cancer screening tests," said Scott Pilla, M.D., M.H.S., an associate professor of medicine at Johns Hopkins University School of Medicine. The analysis used data from the Global Burden of Disease network and World Health Organization databases to model the impact of scaling up six evidence-based services: blood pressure control, statin therapy, glucose control, and screening for colon, breast, and cervical cancers.
Treatment targets were based on major clinical guidelines, including the American Heart Association/American College of Cardiology's 2026 dyslipidemia guideline for statin use and the American Diabetes Association's recommendation for hemoglobin A1c below 7.0%. The researchers noted that the study does not offer specific strategies for improving access to preventive care, but the findings should inspire clinicians and patients to prioritize blood pressure management through lifestyle measures and medication. Previous research, such as the American Heart Association's The lowdown on high blood pressure: what you need to know, has emphasized the importance of awareness and control.
The implications are significant for global health policy. Non-communicable diseases account for roughly three out of five deaths worldwide, with 73% occurring in low- and middle-income countries. By demonstrating the potential to save over half a million lives each year through hypertension control alone, the study underscores the urgent need to strengthen preventive care infrastructure. As the American Heart Association's Millions are unaware of heart risks that don't start in the heart campaign highlights, many people remain unaware of their risks, making screening and treatment expansion critical.
The findings also align with broader trends showing that while Heart disease, stroke deaths down, yet still kill more in U.S. than any other cause, cardiovascular disease remains the leading cause of death globally. The study's authors suggest that future research should explore implementation strategies to bridge the gap between current care and optimal preventive services.
