Meta-analysis: Outcomes of non-invasive diagnostic modalities for the detection of coronary artery disease

Outcomes of non-invasive diagnostic modalities for the detection of coronary artery disease: network meta-analysis of diagnostic randomised controlled trials – The BMJ (free)

Among patients with low risk acute coronary syndrome, stress echocardiography, cardiovascular magnetic resonance, and exercise electrocardiograms resulted in fewer invasive referrals for coronary angiography than coronary computed tomographic angiography, without apparent impact on the future risk of myocardial infarction. Similarly, for outpatients with suspected stable angina, an initial strategy based on functional testing might be preferable, resulting in fewer referrals for invasive coronary angiography and revascularization, without a statistically significant difference in the future risk of MI.
