Abstract
To analyse the relationship between initial exercise parameters and peak oxygen consumption and prognosis in 96 patients with congestive heart failure. Comparison of responses during the initial 6 min of cardiopulmonary exercise testing (Naughton modified protocol) in patients stratified to the Weber classification, and analysis of their predictive value with respect to peak oxygen uptake and prognosis. All patients had a left ventricular ejection fraction PPP<0·003) was an independent predictor of mortality. In patients with congestive heart failure, the initial 6 min parameters of a cardiopulmonary exercise test have additional value in the assessment of clinical severity and prognosis. This may be of clinical relevance since a limited incremental exercise protocol may be more objective than more traditional 6 min walking tests and less demanding.Keywords
