Abstract: Many studies have shown a strong
association between numerous variables from a cardiopulmonary exercise
(CPX) test and prognosis in patients with heart failure with reduced
ejection fraction (HFrEF). However, few studies have compared the
prognostic value of a majority of these variables simultaneously, so
controversy remains regarding optimal interpretation.
