| Description | Heart failure with reduced ejection fraction (HFrEF) is accompanied with dyspnea of various etiologies, one of them being myopathy of respiratory muscles. The goal of the study was to objectivize the effect of home training of expiratory muscles (EMT) using a Threshold PEP® trainer on functional lung capacity, mouth occlusion pressures, chest expansion, dyspnea and fatigue in HFrEF patients. 32 consecutive patients with stable HFrEF were included in the prospective study. The patients were divided into intervention and no intervention group - 16 patients who performed EMT in the intervention group and the remaining 16 patients as a control group with no intervention. After 10-weeks of EMT maximal expiratory pressure increased significantly from 7.59 to 9.49 kPa, maximal inspiratory pressure increased from 4.80 to 7.20 kPa, both forced expiratory volume in one second and peak respiratory flow also increased. Maximal expiratory pressure was found to have a decreasing trend in the control group together with a significant decrease in maximal inspiratory preasure. Expiratory muscle training significantly improved functional lung capacity, increased strength of respiratory muscles characterised by mouth occlusion pressures, decreased subjective perception of stress dyspnea and fatigue of patients with stable HFrEF. |
