Brief Summary:
Approximately half of patients with acute chest pain, a very common reason for emergency department visits worldwide, have a cardiac cause. Two-thirds of patients with a cardiac cause are eventually diagnosed with a so-called non-ST-elevation myocardial infarction. The diagnosis of non-ST-elevation myocardial infarction is based on a combination of symptoms, electrocardiographic changes, and increased serum cardiac specific biomarkers (high-sensitive troponin T). Although being very sensitive of myocardial injury, increased high-sensitive troponin T levels are not specific for myocardial infarction. Invasive coronary angiography is still the reference standard for coronary imaging in suspected non-ST-elevation myocardial infarction. This study investigates whether non-invasive imaging early in the diagnostic process (computed tomography angiography (CTA) or cardiovascular magnetic resonance imaging (CMR)) can prevent unnecessary invasive coronary angiography. For this, patients will be randomly assigned to either one of three strategies: 1) routine clinical care and computed tomography angiography early in the diagnostic process, 2) routine clinical care and cardiovascular magnetic resonance imaging early in the diagnostic process, or 3) routine clinical care without non-invasive imaging early in the diagnostic process.
