Music therapy could help heart patients

June 22, 2009 It turns out a catchy tune may also do your heart and lungs some good.

A study in the journal Circulation suggests music therapy may help heart patients.

Researchers tested 24 young and healthy volunteers in a lab. They listened to classical music while doctors monitored blood pressure, breathing and heart rates.

Fast tempo music tended to increase breathing blood flow. Slow music had the opposite effect. Blood vessels actually narrowed or widened depending on the pace.

Researchers say the next step is to test the effects in older heart patients to see if the songs produce the same robust changes.
