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 manubrium is the uppermost bone of the sternum and can be felt just below the neck. The body of the sternum lies below the manubrium and is the longest bone in the sternum. The bottom part of the sternum is made up of the xiphoid process, which is a small pointed bone attached to the body of the sternum.
