Conclusions In patients presenting with suspected angina due to coronary heart disease, the addition of computed tomography coronary angiography Clarifies the diagnosis: 1 in 4 Increases the diagnosis of CHD but appears to reduce the diagnosis of angina due to CHD Alters subsequent investigations: 1 in 6 Changes treatments: 1 in 4 Does not affect short-term anginal symptoms May increase coronary revascularisation and reduce fatal and non-fatal myocardial infarction
