Abstract		Objectives: Sarcopenia is common in chronic obstructive pulmonary disease (COPD) and may contribute to increased cardiometabolic risk. Interventions to reduce cardiometabolic risk in advanced COPD have been scarcely studied. We have investigated the cardiometabolic effect of a short-term high-intensity rehabilitation program in sarcopenic and nonsarcopenic patients with advanced COPD. Design: Prospective observational study. Setting: Inpatient 4-week short-term high-intensity pulmonary rehabilitation program at the University Clinic Golnik, Slovenia. Participants: 112 stable COPD patients (66 +/- 8 years, 85% GOLD III/IV, 66% men). Measurements: Blood biomarkers were assessed at baseline and after rehabilitation. Sarcopenia was assessed at baseline (skeletal muscle index <7.23 kg/m2 for men and <5.67 kg/m2 for women, as measured by whole-body dual energy X-ray absorptiometry. Insulin resistance (IR) was defined as homeostasis model assessment of insulin resistance (HOMA-IR) above 2.5. Results: IR and sarcopenia were detected in 59% and 55% of patients, respectively. In contrast to sarcopenic patients, rehabilitation decreased HOMA-IR (2.8 to 1.9, P = .031), fat mass index (10.1 to 9.7 kg/m2, P = .013), waist circumference (103 to 101 cm, P = .002), and low-density lipoprotein cholesterol (3.2 to 3.0 mmol/L, P = .034) in nonsarcopenic patients. A decrease in total cholesterol levels was observed in both groups. Conclusions Sarcopenia affects the modification of cardiometabolic risk markers by short-term high-intensity pulmonary rehabilitation in advanced COPD patients.
