Electrical Stimulation For Cardiac Assistance

Abstract

PURPOSE: The aim of this preliminary study was to evaluate the effects of low-frequency electrical stimulation of quadriceps and calf muscles on global exercise capacities, skeletal muscle metabolism, calf muscle volume, and cardiac output in patients with chronic heart failure. METHODS: Fourteen patients with chronic heart failure (mean age of 56.4 years +/9.1 SD; mean radionuclide left ventricular ejection fraction of 22.3% +/8.8 SD) underwent 5 weeks (1 hour per day, 5 days per week) of low-frequency electrical stimulation of quadriceps and calf muscles. RESULTS: Low-frequency electrical stimulation was well tolerated. Exercise capacity and the calf muscles volumes increased significantly after rehabilitation in comparison with prior rehabilitation (the peak oxygen consumption increased from 17.2 mL/(kgmin) +/5.3 SD to 19.6 mL/(kgmin) +/5.9 SD; the anaerobic threshold increased from 12.3 mL/(kgmin) +/3.2 SD to 15.2 mL/(kgmin) +/3.3 SD; the 6-minute walking test increased from 419 m +/122 SD to 459 m +/114.3 SD; the gastrocnemius volume increased from 259.4 cm3 +/58 SD to 273.4
