Abstract
- INTRODUCTION: Slow breathing training (SBT) has been proposed as a new nonpharmacologic treatment in patients with chronic heart failure (CHF). OBJECTIVES: The aim of this study was to assess the effects of SBT on exercise capacity, hemodynamic parameters, and sleep respiratory patterns in a relatively large sample of CHF patients. PATIENTS AND METHODS: A crossover open study was conducted. Patients completed, in a random order, 10- to 12-week SBT, with 2 15-minute sessions of device-guided SBT each day, reaching 6 breaths/min, and a 10- to 12-week follow-up under standard care. Clinical data collection, polysomnography, echocardiography, 6-minute walk test (6MWT), and laboratory tests were performed. RESULTS: A total of 96 patients (74 men, 22 women) in New York Heart Association classes I-III, with an average age of 65 years and an ejection fraction (EF) of 31%, completed the study. Home-based SBT was safe. After training, EF and 6MWT distance improved (EF: 31.3% ±7.3% vs 32.3% ±7.7%; P = 0.030; 6MWT: 449.9 ±122.7 m vs 468.3 ±121.9 m; P
