The aim of this study is to investigate the effect of high-intensity interval training and moderate intensity continuous training on cardiopulmonary functions in chronic heart failure.
enroll chronic heart failure patients into 3 randomized controlled group
perform cardica rehab for 12 weeks, compare primary and secondary endpoints between baseline and 12 weeks results
