New research finds high blood pressure in young adulthood may increase the risk of cardiovascular and kidney disease later in life, underscoring the need to maintain healthy blood pressure earlier than often assumed.
High blood pressure (hypertension) is the leading cause of cardiovascular disease and premature death worldwide and is the most common modifiable risk factor for heart disease and stroke. Medical experts note that prolonged elevated blood pressure in younger adults can lead to earlier cardiovascular and kidney events.
Study details
– Researchers analyzed health records for 291,887 adults from the Korean National Health Insurance Service database.
– Each person was 30 years old between 2002 and 2004 and had routine health screenings between ages 30 and 40.
– Participants had no prior history of heart or kidney disease before age 40.
– Investigators calculated cumulative blood pressure between ages 30 and 40 to capture both how high readings were and how long they stayed elevated.
– Participants were then followed for about 10 years after age 40. Heart and kidney disease diagnoses were identified from national health records; chronic kidney disease diagnoses were confirmed by laboratory tests during follow-up.
Key findings
– People whose blood pressure remained elevated from age 30 to 40 had higher risks of heart and kidney disease after age 40.
– About a 10 mm Hg higher systolic (top number) blood pressure over roughly a decade was associated with a 27% higher risk of heart disease and a 22% higher risk of kidney disease.
– About a 5 mm Hg higher diastolic (bottom number) blood pressure over the same period was associated with a 20% higher heart disease risk and a 16% higher kidney disease risk.
Clinical context and recommendations
– The American Heart Association’s 2025 High Blood Pressure Guideline recommends treating stage 1 hypertension (after 3 to 6 months of lifestyle modification) in adults with a predicted 10-year cardiovascular risk.
– Experts caution that 10-year risk calculators can underestimate longer-term risk in younger patients. Clinicians should screen and manage elevated blood pressure earlier and individualize treatment based on lifetime risk trajectory.
Takeaway
The study reinforces that elevated blood pressure in the 30s is not benign. Working with a healthcare professional to monitor and lower blood pressure and adopting heart-healthy habits earlier in life can help reduce the chance of future heart and kidney disease.
