Why the study?
Does the time course of oxygen consumption recovery (postexercise T1/2 VO2) measure the impairment of the circulatory response to exercise in patients with chronic heart failure?
Does the time course of oxygen consumption recovery (postexercise T1/2 VO2) measure the impairment of the circulatory response to exercise in patients with chronic heart failure?
The time course of oxygen consumption recovery may represent a simple criterion for measuring the impairment of the circulatory response to exercise in patients with chronic heart failure.
May support T1/2 VO2 recovery as a marker of circulatory impairment in CHF; hypothesis-generating pending prospective validation.
Postexercise T1/2 VO2 increases when CHF worsens, perhaps in part a result of slower kinetics of recovery of muscle energy stores. The time course of oxygen consumption recovery may represent a simple new criterion for measuring the impairment of the circulatory response to exercise in CHF, even submaximal exercise.
