Breathing Exercises to Strengthen Lungs in Hospitalized Heart Failure Patients

This trial is testing whether inspiratory muscle training—a set of guided breathing exercises using a handheld device—can help people hospitalized with heart failure rebuild the strength of their breathing muscles. The study compares two groups: one that does the actual breathing exercises and one that does a similar-looking but less challenging version, while both groups receive the hospital's standard heart failure care.

When people spend time in the hospital, their muscles—including the muscles that help them breathe—can become weaker. This trial wants to find out if these breathing exercises can prevent that weakness and help patients recover faster and return home sooner.
