Cardiopulmonary exercise testing (CPX) is an integral tool for assessing the clinical status and prognosis of patients with heart failure (HF). The present investigation examined differences in CPX variables and prognosis according to reason for test termination. One hundred eighty-three patients with HF (69% men, 31% women; mean age 53 +/- 13 years, left ventricular ejection fraction at rest 24.3 +/- 9.9%) underwent CPX in which the minute ventilation/carbon dioxide production slope, peak… CONTINUE READING
