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.
The sternum is a natural âshieldâ that protects the important organs in the thoracic cavity â the heart and great blood vessels. It has three parts known as the manubrium (top), body of the sternum (middle) and xiphoid process (bottom).
