Abstract

We describe a 43-year old man with #congestive heart failure (CHF) with markedly reduced ejection fraction and New York Heart Association Class 3 to 4 symptoms. After a 6-minute walk test showed a 140 m distance, he performed 6 weeks of walking sessions on a weight-supporting lower body positive #pressure treadmill (LBPP). Unloading 40% of his body weight he was able to progressively increase the duration of the walking sessions, exhibited a post-session diuretic effect and dramatically increased his exercise capacity on a 6-minute walk test. He rated his satisfaction with the sessions as maximal. His functional class improved to class 2, remaining stable at 1-year follow-up. We conclude that repeated sessions of ambulation on a weight-supporting LBPP treadmill may benefit patients with CHF with reduced ejection fraction and poor functional capacity. We describe a 43-year old man with congestive heart failure (CHF) with very low functional capacity who demonstrated a marked improvement in 6-minute walk distance and functional class after 6 weeks of walking sessions on a weight support treadmill. The patient is a 43-year old African American overweight man with a long history of hypertension who presented 3 years ago with signs and symptoms of congestive heart failure (CHF). #Echocardiography revealed a left ventricular ejection fraction of 25% and coronary angiography exhibited normal coronary anatomy. He received an implantable cardio-defibrillator and was treated with carvedilol 25mg bid, enalapril 20mg qd, #furosemide 40mg qd, spironolactone 25mg qd and fixed-dose #hydralazine 37.5 mg-isosorbide dinitrate 20 mg tid.
