Hypertensive Kidney Disease Deaths Surge 48% Over 25 Years, Revealing Persistent Racial and Regional Disparities

Deaths from hypertensive kidney disease, a condition caused by high blood pressure, have increased by 48% in the United States over the past 25 years, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2025. The study, which analyzed data from the CDC WONDER database from 1999 to 2023, found persistent and significant disparities across racial, ethnic, gender, and geographic lines, underscoring the ongoing challenges in addressing health inequities.

The age-adjusted mortality rate for hypertensive kidney disease rose from 3.3 per 100,000 people in 1999 to 4.91 per 100,000 in 2023, resulting in 274,667 deaths among individuals aged 15 and older during this period. Black individuals had the highest average death rate at 10.37 per 100,000, more than three times the rates observed in other racial groups, which ranged from 3.33 to 3.90 per 100,000. Hispanic individuals also faced elevated risks, with a 15% higher mortality rate compared to non-Hispanic individuals.

Men were more affected than women, with a 22% higher mortality rate among those with renal failure. Geographically, the South had the highest overall death rates, with Washington, D.C. (7.6 per 100,000), Tennessee (5.9), and Mississippi (5.83) recording the highest age-adjusted mortality rates. These findings align with the American Heart Association's recent guidelines and advisories, which emphasize early treatment of high blood pressure and the impact of social factors on high-risk populations.

High blood pressure is the second leading cause of end-stage kidney disease and contributes significantly to morbidity and mortality globally. The study's lead researcher, Joiven Nyongbella, M.D., stressed that hypertension isn't just a risk for strokes or heart attacks but also a major cause of kidney disease and death, particularly in Black and Hispanic communities. The research highlights the urgent need for improved screening and management of high blood pressure to reduce the risk of hypertensive kidney disease, especially in communities at higher risk.

However, the study has limitations, including reliance on death certificate data, which may contain errors, and the lack of individual health factors like access to care or medication use. The findings are considered preliminary until published in a peer-reviewed journal, but they provide critical observational data pointing to a concerning rise in deaths and persistent health disparities that demand targeted public health interventions.
