Approximately 8-10 million patients complaining of chest pain present to an Emergency Department (ED) annually in the United States. These patients are a challenge to healthcare providers, who are tasked with determining whether these symptoms are due to an acute coronary syndrome (ACS) or a non-ACS cause. Missing the diagnosis of ACS is associated with high rates of morbidity, mortality, and malpractice claims. Therefore, to avoid missing the diagnosis of ACS, patients with chest pain typically undergo extensive evaluations at an estimated cost of $10-13 billion annually. However, less than 10% of these patients are ultimately diagnosed with ACS. As the US healthcare system shifts towards a value-based model, it is clear that the current care patterns for acute chest pain, which fail to focus health system resources, such as hospitalization and cardiac testing, on patients most likely to benefit, are not sustainable.
