Long Term Prognostic Value of a Negative Work-Up for Acute Coronary Disease in Emergency Department Chest Pain Patients Without Known Coronary Artery Disease: A Cohort Study

Patients who present to ED with potentially cardiac chest pain but who do not have known CAD, and have non-ischaemic ECGs and troponin assays below the 99th percentile are at low risk of cardiac death or MI in long-term follow-up. This challenges the recommendation for routine functional or anatomic testing.
