Answer: An acute episode of chest discomfort could be related to a condition called angina, which describes discomfort in the chest related to coronary artery disease. Moderate to severe chest discomfort associated with nausea, vomiting, sweating, shortness of breath, or exertion could be related to your heart and signs of a heart attack. In this situation you should call 911 and be brought to the emergency department for further evaluation. If your symptoms are mild and intermittent you should contact your doctor immediately. Chest pain is a serious condition that needs a timely and thorough evaluation to ensure that your heart is in good shape.
