Patients were divided into three groups: HF with preserved ejection fraction (HF<i>p</i>EF), HF with mildly reduced or reduced ejection fraction (HF<i>mr</i>EF/HF<i>r</i>EF), and patients without HF (control). These groups were further stratified by sex.<h4>Results</h4>One hundred seventy-eight patients underwent CPET-SE testing, of which 40% were femalesFrontiers in cardiovascular medicine1098395https://www.ebi.ac.uk/biostudies/studies/S-EPMC9939638biostudies-literatureSex differences in heart failure patients assessed by combined echocardiographic and cardiopulmonary exercise testing.PMC9939638Sadeh BShimiaie JArnold JHKeren GShacham YTopilsky YBen Gal YLaufer-Perl MGhermezi MRozenbaum ZGranot YBarak OHavakuk OfalseSex differences in heart failure patients assessed by combined echocardiographic and cardiopulmonary exercise testing.<h4>Background</h4>We aimed to test the differences in peak VO₂ between males and females in patients diagnosed with heart failure (HF), using combined stress echocardiography (SE) and cardiopulmonary exercise testing (CPET).<h4>Methods</h4>Patients who underwent CPET and SE for evaluation of dyspnea or exertional intolerance at our institution, between January 2013 and December 2017, were included and retrospectively assessed.
