Scaling up the management of high blood pressure could prevent more than 518,000 deaths from cardiovascular disease annually across 20 countries, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2026. The meeting, held in Arlington, Virginia, from October 7-11, 2026, is a premier scientific exchange focused on recent advances in high blood pressure research and its relationship to cardiac and kidney disease, stroke, obesity, and genetics.
The modeling analysis examined health data from 20 upper- and lower-middle-income countries with the highest numbers of deaths from noncommunicable diseases (NCDs). Researchers estimated the number of lives that could be saved each year if six evidence-based preventive services were increased to match the levels seen in high-performing U.S. health systems—approximately 80% of eligible patients. The services included blood pressure control, statin treatment for high cholesterol, glucose control in people with diabetes, and screening for colon, breast, and cervical cancers.
Among these interventions, hypertension control prevented the most deaths, with an estimated 518,476 annual cardiovascular deaths averted. Statin therapy and glucose control followed, preventing 340,682 and 309,520 deaths, respectively. Colon cancer screening was the most effective cancer screening, preventing 206,767 deaths each year. The benefits were particularly pronounced in lower-middle-income countries, where 223,655 deaths could be prevented annually through better blood pressure management, compared to 223,282 in upper-middle-income countries.
"In this study, we analyzed existing data to assess if expanding use of NCD preventive healthcare services across 20 countries worldwide could reduce cardiovascular death," said Scott Pilla, M.D., M.H.S., an associate professor of medicine at Johns Hopkins University School of Medicine in Baltimore. "We found that expanding treatment of high blood pressure to more people prevented the most deaths, followed by more broad use of statin medications for high cholesterol and managing blood sugar in people with Type 1 or Type 2 diabetes."
Despite the potential, the study revealed substantial gaps in preventive care. Only about one in five adults with hypertension in the 20 countries had their blood pressure controlled below 140/90 mm Hg, the threshold for initiating medication according to the American Heart Association's 2025 Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults. The guideline recommends a treatment target of less than 130/80 mm Hg for adults with hypertension. Similarly, only 16% of individuals with high cholesterol used statins, 39% of those with diabetes had optimal blood sugar levels, and cancer screening rates ranged from 14% to 26%.
"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." Jones, who was not involved in the study, is dean and professor emeritus of the University of Mississippi School of Medicine.
The study's limitations include 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 journal. The abstract will be published in the Hypertension Scientific Sessions 2026 Supplement of the Hypertension journal on November 17, 2026.
