Why the study?
Does peak oxygen uptake efficiency (POUE) provide better prognostic value than oxygen uptake efficiency slope (OUES) in patients with chronic heart failure?
Does peak oxygen uptake efficiency (POUE) provide better prognostic value than oxygen uptake efficiency slope (OUES) in patients with chronic heart failure?
Peak oxygen uptake efficiency (POUE) is a stronger independent predictor of adverse events than oxygen uptake efficiency slope (OUES) in patients with chronic heart failure.
No takes yet. Share an insight, caveat, or question.
POUE may enhance prognostication in chronic HF; hypothesis-generating and requires prospective validation before practice change.
Toste et al. (2011) studied this question.
