Does cardiopulmonary exercise testing (CPX) equally reflect disease severity in patients with HFrEF and HFpEF?
Cardiopulmonary exercise testing is a valuable tool for assessing disease severity in heart failure patients regardless of ejection fraction phenotype.
The results of the current study indicate CPX equally represents disease severity in HFrEF and HFpEF patients. This is a novel finding supporting the key role of CPX in the clinical follow-up of HF patients irrespective of LVEF and cardiac phenotype.
Guazzi et al. (Mon,) studied this question.
