Breathing exercise for heart failure symptoms

This study tests whether special breathing exercises—done alone or while doing a mental task—can improve memory and thinking skills in people with heart failure. Researchers want to see if training your breathing muscles helps your brain work better.

This trial tests whether slow, paced breathing can improve heart rate variability, which is a sign of heart health, in people with heart failure. If you join, you'll practice this breathing technique and help researchers see if it helps your heart.

This study tests a breathing exercise program to strengthen the muscles you use to breathe, which may help you feel better and be more active despite heart failure. You must have stable heart failure and not have had recent heart problems or surgery.

This study tests a breathing exercise device to strengthen the muscles you use to breathe, while you are in the hospital waiting for a heart pump or heart transplant. It may help you feel stronger and breathe easier.

This trial studies whether a specific gentle exercise routine (Baduanjin, “eight-silken-movement”) plus skills to build self-confidence can help people with chronic heart failure. It’s meant for people who are stable and can do prescribed exercise testing and sessions.

This study tests whether using a high-flow nasal cannula, a device that delivers moistened oxygen through the nose, while exercising on a treadmill helps people with heart failure walk or exercise longer. It may improve your exercise tolerance and quality of life during cardiac rehabilitation.
