Background: Peak oxygen uptake (VO2peak), assessed by maximal cardiopulmonary exercise testing (CPET), is a powerful predictor of cardiovascular morbidity and mortality. In clinical practice, the use of CPET is often not feasible or desirable in (older) frail patients.1 In the last decades, several exercise and non-exercise-based algorithms to predict VO2peak were evaluated.2 These prediction models are less accurate than CPET, yet easily accessible and applicable.3 Overall, reviews showed low to moderate correlation for non-exercise algorithms [r = 0.66–0.86, and SEE (standard error of estimate) 3.82–7.31 mL/kg/min] and submaximal exercise-based algorithms (r = 0.21–0.70, and SEE 2.50–4.43) in a healthy population.2,4,5 However, elderly patients with chronic diseases were typically excluded in the development and validation of these models.6 The current study aimed to investigate the accuracy of two self-reported questionnaires to predict VO2peak in chronic heart failure (CHF) patients; the FitMáx©-questionnaire (hereafter FitMáx) (see Supplementary material online for the full English version),7 and The Fitness Calculator (HFC),8 the latter is currently advised in healthy men and women by the American Heart Association.2
