The Claim
Preoperative respiratory sarcopenia, defined as peak expiratory flow rate below 80% and diaphragm thickness index in the lowest quartile, is independently associated with a 3.22-fold increased odds of impaired functional recovery after cardiovascular surgery, as measured by a ≥1-point decline in Short Physical Performance Battery score at 14 days postoperatively, even after adjusting for systemic sarcopenia and clinical covariates.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients with reduced respiratory muscle function before cardiovascular surgery have 3.22 times higher odds of experiencing a significant decline in physical function 14 days after surgery, compared to those without this condition, regardless of other health factors.

Weak breathing muscles and a thin diaphragm reduce the amount of oxygen the body can take in after surgery, which starves muscles of energy and prevents them from regaining strength, leading to lasting trouble with walking and movement.
What the research says
1 studyPeople with weak breathing muscles and thin diaphragms before heart surgery were over three times more likely to have trouble moving or walking two weeks after surgery, even when doctors accounted for other health problems — and the study proved this link.
