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 adult sternum form the anterior midline of the thoracic wall and has 3 components. The manubrium is a broad triangular bone that articulates with the clavicles and the cartilage of the first pair of ribs. The body attaches to the inferior surface of the manubrium and articulates with the cartilage of ribs 2-7.
