Effective management of high blood pressure could prevent more than 518,000 annual deaths from cardiovascular disease in 20 countries, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2026, held in Arlington, Virginia, October 7-11. The meeting serves as a premier scientific exchange focused on recent advances in basic and clinical research on high blood pressure and its relationship to cardiac and kidney disease, stroke, obesity, and genetics.
The modeling analysis, led by Scott Pilla, M.D., M.H.S., an associate professor of medicine at Johns Hopkins University School of Medicine, assessed whether expanding preventive healthcare services across 20 upper- and lower-middle-income countries could reduce cardiovascular deaths. Researchers applied statistical models to estimate the number of lives that could be saved annually if six evidence-based services were increased to match the levels of high-performing U.S. health systems—approximately 80% of eligible patients. The services included control of blood pressure, treatment with statins when indicated, glucose control in people with diabetes, and screening for colon, breast, and cervical cancers.
The study found that hypertension control could prevent 518,476 annual cardiovascular deaths, followed by statin treatment for high cholesterol at 340,682 deaths and glucose control for people with Type 1 or Type 2 diabetes at 309,520 deaths. Increasing colon cancer screening to 80% could prevent 206,767 colon cancer-related deaths each year. Improving blood pressure control prevented the greatest number of deaths out of any preventive service, especially in upper-middle-income countries (223,282 annual deaths) and lower-middle-income countries (223,655 annual deaths).
Despite the potential impact, the analysis revealed substantial gaps in care. Only about one in five adults with hypertension in the 20 studied countries had blood pressure controlled below 140/90 mm Hg. Similarly, 16% of individuals with high cholesterol used statins, 39% with diabetes had blood sugar below optimal levels, and only 14% to 26% underwent routinely indicated cancer screenings. The treatment goal for adults with hypertension, based on the American Heart Association's 2025 Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults, is less than 130/80 mm Hg. Statin therapy eligibility followed the American Heart Association/American College of Cardiology's 2026 dyslipidemia guideline criteria.
Non-communicable diseases are responsible for roughly three out of five deaths globally, with approximately 73% of these deaths occurring in low- or middle-income countries. Cardiovascular disease accounts for more of these deaths than other chronic conditions such as diabetes, cancers, and chronic respiratory illnesses. The researchers noted that 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.
"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 American Heart Association's 2025 guideline writing committee and past volunteer president of the Association. "Treatment of high blood pressure to goal leads to longer lives and also healthier lives. This study should inspire clinicians and patients to give more attention to appropriate management of high blood pressure using both lifestyle measures and medication."
The study has limitations, including limited data on preventive care use in some countries and a lack of specific strategies for improving access. The findings are considered preliminary until published as a full manuscript in a peer-reviewed scientific journal. The abstract will be published in the Hypertension Scientific Sessions 2026 Supplement of the Hypertension journal.
