The relationship between low levels of albuminuria and mortality among adults without major cardiovascular risk factors

Eur J Prev CardiolPublished

  • Prospective cohort study

Authors' conclusion

Adults with elevated levels of albuminuria within the low range (UACR <30 mg/g) and no major cardiovascular risk factors had elevated risks of cardiovascular and all-cause mortality. The risk increased linearly with higher albuminuria levels.
