Usefulness of peak oxygen consumption in predicting outcome of heart failure in women versus men.
This investigation finds that percent of predicted maximum oxygen consumption, an age- and gender-adjusted measurement of exercise, capacity, describes the degree of functional impairment in women more accurately than peak oxygen consumption. This evidence must be considered when cardiopulmonary metabolic parameters are used for prognostic stratification of women with heart failure.
