Researchers at Cedars-Sinai Medical Center have found that patients with shortness of breath can have a higher risk of dying from cardiac disease than patients without symptoms, and even than patients with typical cardiac pain.
The sternum, commonly known as the breastbone, is a long, narrow flat bone that serves as the keystone of the rib cage and stabilizes the thoracic skeleton. Several muscles that move the arms, head, and neck have their origins on the sternum.
I guess one could think of the sternum as the backbone that holds the ribs together, keeps them in place. The sternum and ribs are a cage like system that protects your hear â¦ t and lungs from injury.
