The purpose of a study by Chati et al. (A-32) was to ascertain the role of physical deconditioning in skeletal muscle metabolic abnormalities in patients with chronic heart failure (CHF). Subjects included ambulatory CHF patients (12 males, two females) ages 35 to 74 years. Among the data collected were the following measurements, during exercise, of workload (WL) under controlled conditions, peak oxygen consumption (Vo2), anaerobic ventilatory threshold (AT), both measured in ml/kg/min, and exercise total time (ET) in seconds.
