The traditional pathway for the evaluation of potential Acute Coronary Syndrome is a clinically and economically inefficient process. Patients entering the hospital for chest pain may be kept for an 8-23-hour stay1, even though close to 80% of these patients have non-cardiac related chest pain2. This extended length of stay is often the result of a large percent of indeterminate test results, strained hospital resources and the time required to assure the absence of an evolving myocardial infarction.
