AB  - This study aims to elucidate the characteristics of patients with severe 
      nonischemic heart failure exhibiting exercise oscillatory ventilation (EOV) and 
      the association of these characteristics with the subjective dyspnea. Forty-six 
      patients with nonischemic heart failure who were classified into the New York 
      Heart Association (NYHA) functional class III underwent cardiopulmonary exercise 
      testing (CPX) and were divided into two groups according to the presence or 
      absence of EOV. We evaluated the patients by using the Specific Activity Scale 
      (SAS), biochemical examination, echocardiographic evaluation, results of CPX and 
      symptoms during CPX (Borg scale), and reasons for exercise termination. EOV was 
      observed in 20 of 46 patients. The following characteristics were observed in 
      patients with EOV as compared with those without EOV with statistically 
      significant differences: more patients complaining dyspnea as the reason for 
      exercise termination, lower SAS score, higher N-terminal pro-brain natriuretic 
      peptide level, larger left atrial dimension and volume, left ventricular 
      end-diastolic volume, higher Borg scale score at rest and at the anerobic 
      threshold, higher respiratory rate at rest and at peak exercise, and higher slope 
      of the minute ventilation-to-CO(2) output ratio, and lower end-tidal CO(2) pressure 
      at peak exercise. Among the subjects with NYHA III nonischemic heart failure, 
      more patients with EOV had a stronger feeling of dyspnea during exercise as 
      compared with those without EOV, and the subjective dyspnea was an 
      exercise-limiting factor in many cases.
