Description
Qin Lu is lead author of a 2026 journal article on using chest muscle size on scans to spot malnutrition in patients with sudden worsening of chronic lung disease, shortened to AECOPD. Such patients often lose muscle, and standard nutrition checks can miss that loss, so the team tested total pectoralis major area, the size of both main chest muscles.
Among 123 patients, 35 were malnourished, and their chest muscle area was clearly lower. Larger muscle area protected against malnutrition even after adjustment. Alone, the measure diagnosed malnutrition fairly well; combined with blood albumin or total protein it performed much better. Muscle area also rose with other good nutrition signs and fell as symptom burden rose.
