Preliminary report of using cardiopulmonary exercise testing guide exercise rehabilitation in patients with chronic heart failure / 中国应用生理学杂志

ABSTRACT

<p><b>OBJECTIVE</b>The exercise rehabilitation in patient with chronic heart failure (CHF) is standard clinical practice, but it is rare using CardioPulmonary Exercise Testing (CPET) guide to prescribe exercise rehabilitation in China.</p><p><b>METHODS</b>We performed symptom limited maximal CPET in 10 patients with CHF, randomly divided into two groups 5 patients as control without exercise and 5 exercise patients used &Delta;50%W intensity to exercise 30 min/d, 5 d/w, x12 w. Before and after 12 w rehabilitation, we evaluated functions.</p><p><b>RESULTS</b>There were no significant difference between two groups patients (P > 0.05). The exercise duration was increased from 8 min to 23 min after rehabilitation (P < 0.001); distance 6 minutes walking was increased from 394 m to 470 m (P < 0.05); score of Minnesota quality of life was decreased from 25 to 3 in exercise group (P < 0.01). However, there were nosignificant changes in control group (P>0.05) and their changes were smaller than those in exercise group (P < 0.01).</p><p><b>CONCLUSION</b>The CPET guiding exercise rehabilitation is safe and effective for patients with CHF.</p>
