The purpose of this research study is to evaluate a better way of diagnosing heart artery disease, heart attack and damage to the heart muscle early on. Currently, it often takes several hours after admission before lab tests will show that there has been any damage to the heart muscle. Although the standard electrocardiogram is quick and non-painful it may miss many cases of significant coronary heart disease. The investigators are proposing that a new entirely non-contact tool, the Magnetocardiograph (MCG), with high accuracy is able to predict the presence of significant coronary heart disease early on before other studies become positive. The investigators hope by this that the investigators can develop an algorithm for better triage and management of patients with chest pain.
