Early Blood Pressure Exposure Linked to Increased Heart and Kidney Disease Risk
Published: March 22, 2026
Elevated blood pressure during young adulthood, even if seemingly within normal ranges, is associated with a significantly increased risk of cardiovascular disease (CVD) and chronic kidney disease (CKD) later in life, according to research presented at the American Heart Association EPI | Lifestyle Scientific Sessions.
Study Findings
A study analyzing data from nearly 300,000 participants in the Korean National Health Insurance Service database revealed that cumulative exposure to blood pressure above 120/80 mm Hg between the ages of 30 and 40 was linked to a substantial increase in adverse events. The research, led by Dr. Hokyou Lee of Yonsei University College of Medicine in Seoul, South Korea, demonstrated that even short-term risk may appear low, long-term exposure to higher blood pressure can accumulate damage over time.
- For every 10 mm Hg higher systolic blood pressure above 120 mm Hg from ages 30 to 40, there was a 27% increased risk for CVD events (HR = 1.27. 95% CI, 1.23-1.32).
- The same exposure was associated with a 22% increased risk for kidney events (HR = 1.22; 95% CI, 1.17-1.28).
- Every 5 mm Hg higher diastolic blood pressure above 80 mm Hg from ages 30 to 40 was linked to a 20% increased risk for CVD events (HR = 1.2; 95% CI, 1.17-1.23).
- This same exposure was associated with a 16% increased risk for kidney events (HR = 1.16; 95% CI, 1.13-1.2).
The study included participants aged 40 years without prior CVD or CKD, with blood pressure measurements taken at ages 30, 40, and at least once in between. The median follow-up period after age 40 was 10.2 years.
Expert Commentary
Dr. Daniel W. Jones, Dean and Professor Emeritus of the University of Mississippi School of Medicine, emphasized the importance of these findings. “This study from Korea emphasizes the risk from high blood pressure begins at an early age and early in the course,” he stated. He also highlighted the value of evaluating cumulative blood pressure over several years to understand the associated risks, suggesting the need for randomized clinical trials to confirm that early treatment of high blood pressure in young adults can effectively reduce the risk of cardiovascular and kidney disease.
Implications for Prevention
Dr. Lee stressed the importance of maintaining optimal blood pressure at all ages. “Early prevention, diagnosis, monitoring and treatment, if needed, are investments in future heart and kidney health,” he said. Timely treatment of elevated blood pressure is crucial to mitigate the effects of prolonged exposure, underscoring the need for regular blood pressure monitoring and management as soon as elevated levels are detected.
