Official title

Short Term Hemodynamic Effects of Controlled Slow Breathing With Biofeedback in Patients With Heart Failure: Normal Healthy Subjects vs. Chronic Ambulatory Heart Failure Patients vs Acute Heart Failure

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Heart failure is associated with faster breathing, which has a negative impact on the functioning of the heart. This leads to fatigue, shortness of breath, and exercise intolerance. It has been shown that when slow breathing technique was taught to patients with heart failure, they had a reduction in their sensation of shortness of breath and an improvement in their exercise performance. The study will compare the short-term effects of controlled slow breathing with biofeedback in normal healthy subjects, acute heart failure, and chronic stable heart failure. The purpose is to see if there is any change in the objective measurements of heart function while breathing at normal rates compared to a controlled slower rate.
