Pulmonary artery enlargement is associated with frailty in humans (Adjusted OR 2.49, 95% CI 1.41-4.41).

Lung function decline and scan findings linked to later frailty

Each 1%-per-year drop in the volume of air forcibly exhaled in one second was linked to 1.47 times the odds of frailty at 10 years.Each 1%-per-year drop in the volume of air forcibly exhaled in one second was linked to 1.47 times the odds of frailty at 10 years.
