## Summary

Looking at five large studies across the US, UK, and China, people with heart or metabolic conditions who were frail had up to 132% higher risk of dying from any cause. Even being slightly weak (pre-frail) raised the risk by 21% to 66%. The link was strongest in people under 65 and those with lower body weight.

## Practical Takeaway

This study suggests frailty checks could matter even for younger adults with heart or metabolic issues.
