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 was the single most effective preventive service, outpacing statin therapy and glucose management in lives saved.
The study's implications are substantial. Non-communicable diseases account for roughly three out of five deaths globally, and approximately 73% of those deaths occur in low- or middle-income countries. Cardiovascular disease alone claims more lives than other chronic conditions such as diabetes, cancers, and chronic respiratory illnesses. Yet the analysis revealed stark 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, and just 16% of individuals with high cholesterol were using statins. These figures highlight a vast, unrealized opportunity to save lives through better use of existing, evidence-based interventions.
"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." Pilla added that while all countries had substantial gaps, lower-middle-income countries had the largest opportunities for improvement, with low rates of hypertension control and high cholesterol management and minimal use of cancer screening tests.
The analysis modeled the impact of raising six preventive services to approximately 80% coverage, matching the levels seen in high-performing U.S. health systems. After hypertension control, statin treatment when indicated could prevent 340,682 annual deaths, and glucose control in people with diabetes could prevent 309,520 deaths. Increasing colon cancer screening to 80% could prevent 206,767 colon cancer-related deaths each year. The benefits of blood pressure control were particularly pronounced in upper-middle-income countries (223,282 annual deaths prevented) and lower-middle-income countries (223,655 annual deaths prevented).
"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 for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults. Jones, who was not involved in the study, noted that following evidence-based recommendations can also reduce the risk of heart failure, stroke, and dementia. "Treatment of high blood pressure to goal leads to longer lives and also healthier lives," he said. "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 research relied on data from the Global Burden of Disease network, the NCD Risk Factor Collaboration, and World Health Organization databases. Treatment targets were defined by major guidelines, including the American Heart Association's 2025 high blood pressure guideline and the 2026 dyslipidemia guideline. The authors acknowledged limitations, including limited data from some countries and the absence of specific strategies for improving access to preventive care. The abstract is scheduled for oral presentation and will be published in the Hypertension Scientific Sessions 2026 Supplement of the Hypertension journal. As preliminary research, the findings are considered until published as a full manuscript in a peer-reviewed journal.
