According to Charles Chambers, MD, director of the Cardiac Catheterization Laboratory at Penn State Hershey Heart and Vascular Institute, patients experiencing a heart attack can exhibit these signs. They may even vomit. Although other diseases or just eating the wrong thing can also lead to the same symptoms, keep in mind that they can also occur during a heart attack.
