  • Title: Direct and indirect assessment of skeletal muscle blood flow in patients with congestive heart failure.
    Author: LeJemtel TH, Testa M, Jondeau G.
    Journal: J Mol Cell Cardiol; 1996 Nov; 28(11):2249-54. PubMed ID: 8938578.
    Abstract:
    Techniques which are currently used to measure skeletal muscle blood flow (SMBF) in patients with congestive heart failure (CHF) are neither convenient nor accurate. They have led to discrepant results in patients with congestive heart failure and are, in part, responsible for the ongoing debate regarding the factors which limit the rise in body oxygen consumption during exercise in these patients. However, direct measurement of SMBF may not be needed during exercise in patients with severe CHF. Their skeletal muscles maximally extract oxygen. Consequently, increase in oxygen consumption by the skeletal muscles is only mediated by a concomitant increase in SMBF. In patients with severe CHF, peak body oxygen consumption attained during maximal exercise closely depends on the rise in SMBF, and thus provides an indirect measurement of SMBF.
