Why the study?
In heart failure, anaerobic threshold has prognostic value but may be indeterminable, and non-concordance between metabolic and ventilatory methods (double threshold) recognized in healthy individuals needed evaluation in HF.
Does the presence of a double anaerobic threshold predict 2-year survival in heart failure patients?
Does the presence of a double anaerobic threshold predict 2-year survival in heart failure patients?
The double anaerobic threshold is frequently observed in heart failure patients and is associated with a decreased ventilatory response during exercise, but it does not independently predict 2-year survival.
No takes yet. Share an insight, caveat, or question.
DT does not predict 2-year HF survival; leaves open its mechanistic link to ventilatory inefficiency.
Rovai et al. (2022) studied this question.
