Importantly, we demonstrated that by combining ventilatory abnormalities and peak exercise oxygen consumption, patients at a particularly high risk for death could be identified. These findings are similar to the data presented in Figures 1, 5, and 7 of the article by Robbins et al.1 In patients with minute ventilation/carbon dioxide production (V̇e/V̇co2) >50 and a peak exercise oxygen consumption <15 mL · kg−1· min−1, we described a mortality rate of 82% (median follow-up time, 552±329 days) compared with a mortality of 22% in patients with a V̇e/V̇co2 <50 and a peak exercise oxygen consumption <15 mL · kg−1 · min−1. In addition, Robbins et al1 state that the value of V̇e/V̇co2 at the anaerobic threshold was almost as strong a predictor of mortality as V̇e/V̇co2 at peak exercise. We also used V̇e/V̇co2 at the anaerobic threshold4 because it predicted outcome better than V̇e/V̇co2 at peak exercise. Robbins et al1 further state that there was a threshold phenomenon regarding V̇e/V̇co2 values, with mortality increasing markedly as values exceeded 40 to 45. Similarly, our data clearly show a marked increase in mortality with values >50. The study by Robbins et al2 had a follow-up period similar to ours; however, they deserve credit for studying a larger patient population and for analyzing data regarding chronotropic responses to exercise.On the basis of these published data,4 we have used exercise-related ventilatory responses in conjunction with peak exercise oxygen consumption to evaluate candidates for transplantation for the past 3 years at the University of Pittsburgh Medical Center. We believe that a proper scientific evaluation of the hypothesis that exercise-related ventilatory responses provide additional prognostic information in heart failure beyond that provided by peak exercise oxygen consumption requires a full recognition of all pertinent, previously published studies. Clearly, this is an important area of clinical research that may have a substantial impact on the management of patients with congestive heart failure.

We agree that their study,R1 along with ours and those of others,R2 strongly support the view that ventilatory responses to exercise must be carefully considered when risk-stratifying patients with severe heart failure. We are also now routinely incorporating the ventilatory response to exercise in our metabolic stress test reports and in our considerations regarding candidacy for cardiac transplantation.
