The Claim

The inclusion of preoperative respiratory sarcopenia in clinical prediction models significantly improves the reclassification of patients at risk of impaired functional recovery after cardiovascular surgery, as measured by a net reclassification improvement of 0.36 and an integrated discrimination improvement of 0.037.

Source: Prognostic significance of preoperative respiratory sarcopenia for functional recovery after cardiovascular surgery.

In plain English

Adding a measure of muscle weakness in the breathing muscles before heart surgery improves the accuracy of models that predict which patients will have trouble recovering their physical function after surgery.

See the scientific wording

Adding preoperative respiratory sarcopenia to clinical prediction models significantly improves the ability to reclassify patients at risk of impaired functional recovery after cardiovascular surgery, as demonstrated by a net reclassification improvement of 0.36 and integrated discrimination improvement of 0.037.

Why this might work

When the breathing muscles are weak and thin before surgery, the body cannot move enough air after the operation, which lowers oxygen levels in the blood and prevents muscles throughout the body from getting the energy they need to recover.

    Doctors can better predict which heart surgery patients will struggle to recover physically by checking their breathing muscle strength and diaphragm thickness before surgery—this simple addition makes their predictions much more accurate.
