Abstract

Exercise performance in patients with heart failure is limited primarily due to a reduction in cardiac output. This results in skeletal muscle hypo-perfusion. Near infrared spectroscopy provides a simple noninvasive method for assessing skeletal muscle oxygenation during exercise. In this paper we review the application of this technique to patients with heart failure and describe excessive limb and respiratory muscle oxygenation as compared to normal subjects. The potential of this technology for monitoring clinical improvement and therapeutic efficacy also is discussed.
