Summary

This trial looks at the effects of adding extra breathing exercises to cardiac rehabilitation on blood flow and blood pressure during exercise.

Who is the study for?
This trial is for adults over 18 who speak English. There are two groups: one with heart failure patients eligible for cardiac rehab, and a healthy control group without lung, heart, or other major diseases. Participants must be able to exercise and give consent. Those with liver disease, uremia, iodide allergies, or poor kidney function (creatinine >1.3 mg/dL) can't join.
What is being tested?
The study tests if breathing muscle training improves blood flow and pressure during exercise when added to standard cardiac rehabilitation in people with heart failure compared to healthy individuals matched by age and sex.
What are the potential side effects?
While the document doesn't list specific side effects of inspiratory muscle training, it's generally considered safe but may include temporary breathlessness or fatigue during the exercises.
