Functional assessment based on cardiopulmonary exercise testing in mild heart failure: A multicentre study.

ABSTRACT:

Aims

In this multicentre study, we compared cardio-pulmonary exercise test (CPET) parameters between heart failure (HF) patients classified as New York Heart Association (NYHA) class I and II to assess NYHA performance and prognostic role in mild HF.

Methods and results

We included consecutive HF patients in NYHA class I or II who underwent CPET in three Brazilian centres. We analysed the overlap between kernel density estimations for the per cent-predicted peak oxygen consumption (VO₂ ), minute ventilation/carbon dioxide production (VE/VCO₂ ) slope, and oxygen uptake efficiency slope (OUES) by NYHA class. Area under the receiver-operating characteristic curve (AUC) was used to assess the capacity of per cent-predicted peak VO₂ to discriminat
