In the assessment of low-risk patients with suspected acute coronary syndrome, the routine use of non-invasive testing has been recommend by international clinical guidelines. However, limited evidence from randomised controlled trials (RCTs) exists to support such recommendations. Although a number of trials have tested the safety and efficacy of CT coronary angiography (CTCA) in this setting, most were underpowered to demonstrate benefits with regards to hard clinical endpoints.
The authors undertook a meta-analysis of RCTs published prior to March 2017 comparing CTCA with standard care in the assessment of patients with acute chest pain.1 Standard care varied across the trials but always incorporated non-invasive functional testing—that is, exercise ECG, stress echocardiography or myocardial perfusion …
