## Summary

As people age, blood stem cells accumulate mutations that cause certain cell lines to expand. This process, called clonal hematopoiesis, is now strongly linked to increased cardiovascular risk in older adults. The mutant blood cells appear to ramp up inflammation, accelerating atherosclerosis and heart failure. This review covers how these rogue clones interact with age-related inflammation and what future therapies might look like.

## Practical Takeaway

This review highlights that age-related blood cell mutations may be an underappreciated driver of heart disease risk.
