Is mild eGFR reduction associated with an increased risk of incident hypertension and cardiovascular events in young adults?
Minor reductions in eGFR in young adults are associated with new-onset hypertension and a significantly higher risk of cardiovascular events, highlighting the importance of early identification.
May signal increased CV risk with mild eGFR decline in young adults but should not yet change practice; leaves open if causal or modifiable.**[[1]](https://www.ahajournals.org/doi/10.1161/JAHA.125.
BACKGROUND: hypertension in young adults (aged 18-39 years) compared with middle-aged (aged 40-49 years) and older adults (aged 50-65 years). METHODS: ) and incident hypertension, stratified by age (18-39, 40-49, and 50-65 years). RESULTS: Among our cohort (mean age, 40.4 years; mean eGFR, 104.9 mL/min), a total of 170 905 (4.6%) individuals developed hypertension among young adults, compared with 279 937 (15.3%) in those aged 40 to 49 years and 588 195 (25.2%) in those aged 50 to 65 years. The adjusted rates of hypertension increased with an eGFR of <100 mL/min, increasing step wise as eGFR declined, and occurred at a higher relative eGFR in young adults compared with older age groups. Among young adults who developed hypertension, cardiovascular events were 6- to 10-fold more common and were more likely with minor eGFR reductions. CONCLUSIONS: Minor reductions in eGFR in younger adults are associated with new-onset hypertension and a higher risk of cardiovascular consequences, suggesting early identification, monitoring, and management may be beneficial.

Ahmed et al. (2026) conducted a cohort in Incident hypertension and mild eGFR reduction. Mild eGFR reduction (<100 mL/min) vs. Normal eGFR / Older age groups was evaluated on Incident hypertension. Minor reductions in eGFR (<100 mL/min) in young adults were associated with increased rates of incident hypertension and a 6- to 10-fold higher risk of cardiovascular events.
