Reduced in vivo skeletal muscle oxygen consumption in patients with chronic heart failure--a study using Near Infrared Spectrophotometry (NIRS).
We used Near Infrared Spectrophotometry (NIRS) during arterial occlusion to measure resting skeletal muscle oxygen consumption in chronic heart failure (CHF) patients and in age-matched healthy volunteers (HVs). ⋯ There is a significant reduction in resting oxygen consumption per gram of tissue in skeletal muscle of patients with CHF.
