Early High Blood Pressure Linked to Increased Heart & Kidney Disease Risk

Exposure to elevated blood pressure during young adulthood—between the ages of 30 and 40—is significantly linked to increased risk of cardiovascular disease (CVD) and chronic kidney disease (CKD) later in life, according to research presented at the American Heart Association’s EPI | Lifestyle Scientific Sessions on March 17-20, 2026, in Boston.

The study, based on data from nearly 300,000 participants in the Korean National Health Insurance Service database, found that even seemingly moderate increases in blood pressure during those critical years can have lasting consequences. Researchers followed participants aged 40 and older without prior CVD or CKD, tracking incident rates of heart attacks, stroke, heart failure, cardiovascular death, kidney replacement therapy, and kidney-related death.

“Young adults often have a very low predicted 10-year risk of heart disease, even when they have elevated or high blood pressure,” said Hokyou Lee, MD, PhD, FAHA, associate professor of preventive medicine at Yonsei University College of Medicine in Seoul, South Korea, in a statement released by the AHA. “Our study’s findings show that blood pressure levels in early adulthood are important even if short-term risk appears low. Long-term exposure to higher blood pressure from early life may accumulate damage over time, increasing the risk of heart and kidney disease in midlife.”

The analysis revealed that for every 10 mm Hg increase in systolic blood pressure above 120 mm Hg between ages 30 and 40, the risk of CVD events rose by 27% (HR = 1.27; 95% CI, 1.23-1.32). The risk of kidney events increased by 22% (HR = 1.22; 95% CI, 1.17-1.28) with the same increase in systolic pressure. Similarly, a 5 mm Hg increase in diastolic blood pressure above 80 mm Hg was associated with a 20% higher risk of CVD events (HR = 1.2; 95% CI, 1.17-1.23) and a 16% higher risk of kidney events (HR = 1.16; 95% CI, 1.13-1.2).

The study’s findings were consistent for both men and women, and the associations remained significant even after adjusting for blood pressure readings taken at age 40. The median number of examination visits between ages 30 and 40 was eight, with a median follow-up of 10.2 years after age 40.

Daniel W. Jones, MD, MACP, FAHA, dean and professor emeritus of the University of Mississippi School of Medicine, and an American Heart Association volunteer expert, emphasized the importance of early intervention. “This study from Korea emphasizes the risk from high blood pressure begins at an early age and early in the course,” Jones said in the AHA statement. “The opportunity in this study to evaluate cumulative blood pressure over several years was important in understanding that risk. The study should encourage the design of randomized clinical trials to document that early treatment of high blood pressure in young adults is effective at reducing risk for cardiovascular and kidney disease.”

Researchers noted a parallel trend of increasing reports of phishing scams targeting individuals with data breach notices, according to Scamicide.com, a website tracking online fraud. The site reported on March 20, 2026, that scammers are exploiting public awareness of data breaches to solicit personal information through deceptive emails and texts. Malwarebytes also reported in November 2025 that phishing emails disguised as spam filter alerts are being used to steal login credentials.

Lee concluded, “Maintaining optimal blood pressure is a concern for every individual, at every age. Early prevention, diagnosis, monitoring and treatment, if needed, are investments in future heart and kidney health. Timely treatment of elevated blood pressure is essential to reduce the effects of years of exposure, which underscores the importance of monitoring and managing blood pressure as soon as a patient has elevated blood pressure levels.”
