BACKGROUND Ventilatory efficiency, commonly assessed by the minute ventilation (VE)-carbon dioxide production (VCO2) slope, is a powerful prognostic marker in the heart failure population. The purpose of the present study is to refine the prognostic power of the VE/VCO2 slope by developing a ventilatory class system that correlates VE/VCO2 cut points to cardiac-related events. METHODS AND RESULTS Four hundred forty-eight subjects diagnosed with heart failure were included in this analysis… CONTINUE READING
