Abstract 19818: Coronary CT Angiography for Suspected Acute Coronary Syndrome in the Era of High-Sensitivity Troponins - A Randomized Multicenter Study
Introduction: It is uncertain whether a diagnostic strategy supplemented by early coronary CT angiography (CCTA) is superior to contemporary standard optimal care (SOC) encompassing high sensitivity troponins for patients suspected of acute coronary syndrome (ACS) in the emergency department. Hypothesis: To assess whether a diagnostic strategysupplemented by early CCTA improves clinical effectiveness compared to contemporary SOC. Methods: In a prospective, open-label, multicentre, randomized trial, we enrolled patients presenting with symptoms suggestive of an ACSat the emergency department (ED) of five community and two university hospitals in the Netherlands. Exclusion criteria included the need for urgent cardiac catheterization, history of ACS or coronary revascularisation. The primary endpoint was the number of patients identified with significant coronary artery disease requiring revascularization within 30 days. Results: The study population consisted of 500 patients of whom 236 (47%) were women (m...
