One of the most difficult aspects of a doctors job, is taking a set of symptoms and diagnosing the illness or injury causing them. Often times, several different illnesses may result in similar symptoms, but will require very different treatment. For this reason, it is important that, if a doctor has doubt regarding a diagnosis, further testing should be done.
One of the most common and dangerous forms of medical misdiagnosis relates to heart attack diagnosis, or coronary artery disease. CAD is a condition that may not show symptoms for many years, yet can ultimately result in a massive heart attack and death. Often times, the first sign of an impending heart attack will be chest pains, which can be misdiagnosed as strained muscles or something similar.
