Impact of congestive heart failure treatment on peripheral microvascular tissue oxygenation

Abstract

The authors evaluated peripheral tissue oxygenation during treatment of acutely decompensated congestive heart failure (CHF) to determine whether differences exist between patients who experienced adverse outcomes (AO), defined as death or readmission within 6months, and patients who did not (non-AO). This prospective, observational study measured differential absorption spectroscopy-derived tissue hemoglobin oxygenation (S tO 2) in CHF patients from presentation through hospital discharge to determine whether differences between the AO and non-AO groups exist. Of 52 patients, 6 died and 27 were readmitted. In the non-AO group, S tO 2 increased from admission to discharge by 5.2% (P
