This review highlights the physiological basis and clinical interpretation of exercise ventilatory efficiency during CPET, which is an independent predictor of mortality in CHF, PH, and COPD.
response to exercise is an independent predictor of mortality in patients with CHF, PH, and COPD. In this article, the underlying physiology, measurement, and interpretation of exercise ventilatory efficiency during CPET are reviewed. Additionally, exercise ventilatory efficiency in varying disease states is briefly discussed.
