Stable chest pain

Coronary artery disease (narrowing of the heart arteries) is the typical cause of angina (cardiac chest pain) and is becoming more common as people live longer with multiple heart disease risk factors (e.g. diabetes, smoking high blood pressure, and high cholesterol). In the UK about 2 million people have angina and about 200,000 are referred to hospital each year for further investigation. There are lots of different tests to investigate suspected angina, but doctors have different opinions as to the best approach, and international guidelines make very different recommendations. This leads to wide practice variation, inefficiency of healthcare resources and it may adversely impact on patient experience and outcomes. What most doctors agree on is that we do too many invasive X-ray angiograms. About 60% of angiograms performed do not find significant narrowing of the heart arteries, and as such, do not lead to a direct change in management for that patient.
Recent UK NICE guidelines recommend a non-invasive CT angiogram as the first-line test for all patients with suspected angina. This one-size-fits-all approach does not recognise individual patient characteristics, risk factors or likelihood of them having disease. Whilst cardiac CT is an excellent test to exclude narrowing of the heart arteries when they are normal, it can lead to over-estimation of severity when moderate disease is present. It has been suggested that this approach may lead to further increases in the rates of invasive angiography, more additional downstream investigations and increased NHS costs, with no difference in patient outcomes. In addition, the recent UK NICE guidelines if fully adopted would require major service reorganisation in every hospital, and large capital and revenue investment to accommodate the 700% predicted increase in cardiac CT capacity. Thus many doctors believe that this major NHS service reorganisation should first be robustly evaluated in the setting of a clinical trial to demonstrate that it is both appropriate and cost-efficient.
The aim of this study is to try to improve the investigation and management of patients with suspected cardiac chest pain (angina), both in terms of NHS resource use and also patient experience and outcomes; producing results that would be highly generalisable across the NHS.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

27 Apr 2022 31 Jul 2025

Patients will have either a computerised tomography cardioangiogram (a CT scan of the heart), a cardiac MRI scan, a stress echocardiogram (an ultrasound scan of the heart) or a nuclear perfusion scan of the heart with single-photon emission computerised tomography (MPS-SPECT), depending on which group they are randomly allocated to and their calculated risk of having heart disease. Patients will also complete three questionnaires at the start of the study and after 6 and 12 months.


Males aged 45 years and over and females aged 50 years and over with atypical or typical angina and at least one major cardiac risk factor (diabetes, peripheral arterial disease, cerebrovascular disease, current or past tobacco use, high blood pressure, dyslipidaemia or a family history of premature coronary artery disease) referred to NHS cardiology outpatient services, requiring further investigation according to NICE CG95 guidelines, and who are deemed suitable for coronary revascularisation if required.

In order to keep the trial generalisable to the UK population at large, only issues related to patient safety/appropriateness will form the exclusion criteria; these will include:1. Prior normal CT coronary angiography (CTCA) within the last 2 years or prior CTCA with extensive calcification2. Clinically unstable cardiac symptoms3. Known coronary artery disease (including previous myocardial infarction [MI], acute coronary syndrome [ACS] or coronary revascularization)4. Contraindication to CTCA or functional cardiac imaging5. Pregnancy and/or breastfeeding6. Known chronic renal failure (eGFR < 30ml/min/1.73m²)7. Inability to give written informed consent

All of the study procedures are part of routine clinical care and no additional procedures will be undertaken. Participants may be less likely to have unnecessary tests. Patients will also have more contact with the clinical care team and have more opportunities to ask questions and be informed about their health, which some patients find helpful.


The study is sponsored by University of Leeds and funded by Heart Research UK; Grant Codes: TR2442/19/24; British Heart Foundation.
