CT coronary angiogram and cardiac CT
Urgent help
This page describes a planned test. If you have chest pain now, especially pain spreading to an arm, neck, jaw or back, or chest pain with sweating, nausea, light-headedness or breathlessness, call 999.
Introduction
CT coronary angiography (CTCA) uses X-rays and a contrast dye to create detailed images of the coronary arteries, the blood vessels that supply the heart muscle. Calcium scoring is a different CT assessment of calcified plaque in those arteries. Dr Anand holds Cardiac CT Accreditation (Level 2) from the British Society of Cardiovascular Imaging.
Why it may be considered
A CT coronary angiogram may be considered when symptoms such as chest pain need further investigation, or to look for narrowing or plaque in the coronary arteries. A clinician will advise whether the test is appropriate for you, explain its limitations and discuss the next steps. A CT scan is not needed for everyone.
Before the scan
You will be told how to prepare, including any changes to food, drink or medicines. Sometimes a medicine is given to slow the heart rate so that clearer images can be taken.
Risks
The scan uses X-rays, which involve a dose of radiation, and an iodine-based contrast dye that can occasionally cause an allergic reaction or affect kidney function. These risks, and whether the test is right for you, are discussed before the scan.
Results and follow up
The results are discussed with you, together with any further tests or treatment that may be needed.
Consultation locations and next steps
Consultations take place at Harley Street Specialist Hospital, Harley Fitzrovia Health in Woodford and Cobham Clinic in Luton. CT coronary angiography and calcium scoring are arranged at One Heart Clinic in Central London.
