Computed Tomography (CT) coronary angiography is a diagnostic imaging technique that visualises the coronary arteries. These are the blood vessels (arteries) that supply oxygen and nutrients to the heart muscles.
Unlike conventional coronary angiography, which involves threading a catheter through blood vessels to inject contrast dye, CTCA relies on advanced technology.
The human heart is a remarkable organ situated in the thoracic cavity between the lungs. It plays a primary role in the circulatory system.
Chambers: The heart has four chambers – two atria (upper chambers) and two ventricles (lower chambers).
Septum: It divides the heart into left and right sides. This ensures that oxygenated and deoxygenated blood do not mix.
Valves: Four valves control blood flow:
Coronary Arteries: These vessels supply the heart muscles with oxygen and nutrients.
The heart goes through a synchronised series of events known as the cardiac cycle. It ensures the continuous flow of oxygen and nutrients to all the organs.
Blood Flow: Here are the steps for better understanding:
Cardiac Cycle: The heart undergoes a series of contractions (systole) and relaxations (diastole) during each heartbeat.
Conduction System: Electrical signals coordinate heart contractions. The sinoatrial (SA) node initiates the signal, followed by the atrioventricular (AV) node.
Blood Pressure: The force of blood against the arterial walls. Systolic pressure is during contraction, and diastolic pressure is during rest.
Cardiac Output: The amount of blood the heart pumps per minute.
CT coronary angiography test can help diagnose various cardiovascular conditions. It presents detailed images of the coronary arteries and the heart.
Coronary Artery Disease (CAD):
Coronary Artery Anomalies: The examination assists in the detection of congenital variations in the structure of arteries.
Aneurysms: It can detect irregular bulges or dilation in blood vessels.
Vascular Abnormalities: The test helps check the structure and integrity of blood vessels, identifying any deformities.
Pulmonary Embolism: It can be used to identify blood clots or emboli in the pulmonary arteries.
CT coronary angiography test can be recommended for individuals with specific clinical indications or risk factors. Healthcare providers may consider CTCA for the following:
Individuals experiencing persistent chest pain or discomfort.
People going through unexplained shortness of breath.
A person with risk factors such as hypertension, diabetes, high cholesterol, obesity and smoking.
Individuals with a history of heart conditions, such as a heart attack.
Whose echocardiogram (ECG) shows abnormalities in heart function or structure.
Patients who have undergone coronary artery bypass graft (CABG) surgery.
CT coronary angiography test offers several advantages as a diagnostic imaging tool. Some of them are:
Non-invasiveness, eliminating the need for catheterisation and reducing associated risks.
Provides high-resolution images, offering detailed visualisation of coronary arteries.
Relatively quick, taking less than an hour, which leads to faster diagnosis.
Offers a comprehensive assessment of coronary artery disease (CAD) as well as information about heart chambers and valves.
Assists in risk stratification by providing details about the extent and severity of coronary artery disease.
Enables early detection of atherosclerosis, plaque buildup, and other cardiac abnormalities.
Applicable to a wide range of patients, including those with chest pain and suspected CAD.

The actual CT coronary angiography test itself may only take a few seconds to minutes. However, considering the setup time and other preparations, the entire CTCA procedure typically lasts around an hour.
Preparation: The patient may receive a numbing medication. This helps minimise discomfort during the injection process.
Electrode Placement: The technician attaches sticky patches (electrodes) to the patient's chest. They are connected to a machine that records the heart rate and rhythm. This information is crucial for synchronising the imaging with the cardiac cycle.
Patient Positioning: The patient lies on their back on a table that smoothly goes into a machine named a CT scanner.
Contrast Dye Injection: It enhances the visibility of blood vessels during the procedure.
Breath-Holding Instructions: During the CT scan, the patient may be instructed to hold their breath for short intervals. This is to reduce chest movement, ensuring sharper images.
Image Acquisition: The CT scanner takes a series of X-ray images. They are processed by specialised software to create detailed cross-sectional views of the coronary arteries.
Following the guidelines before and on the day of the CT coronary angiography is essential. This helps the healthcare team to ensure a smooth and successful imaging procedure.
Prior to undergoing a CT coronary angiography test, patients are advised to follow pre-procedural instructions. The patient is instructed to fast for four hours before the procedure. However, they can take water as usual.
Here’s what they can expect:

Physical Evaluation | Observation of vitals (heart rate, blood pressure, oxygen saturation, etc.) |
IV Line | Intravenous (IV) line for the administration of contrast dye |
Anaesthesia Administration | No anaesthesia (sedation may be considered for patients with anxiety or claustrophobia) |
The recovery process involves observation for any adverse reactions. The healthcare facility ensures that the patient is stable before discharge. Here’s what you can expect:
Following a CT coronary angiography test, patients are monitored for a short duration to ensure there are no immediate complications.
Immediate Post: Procedure Monitoring: Vital signs such as heart rate and blood pressure are assessed to ensure the patient's stability.
Care Instructions: Patients receive specific guidelines, which may include staying hydrated and any restrictions on medications.
These follow-up measures are crucial in ensuring a comprehensive approach to cardiovascular health. Patients can anticipate these once discharged:
Normal Activities Resumption: Individuals are usually encouraged to restart daily work, including office and exercise.
Adequate Hydration: It is often recommended to flush out the contrast dye from the system.
Long-term Monitoring: Patients are advised to be vigilant for any signs or symptoms. This may include allergic reactions, excessive bleeding, or persistent pain.
The first checkup after CT coronary angiography is important for reviewing the results and discussing any identified issues. It helps to plan further in managing the patient's cardiovascular health.
Report Assessment: The specialist discusses the CTCA findings with the patient. They explain any identified coronary artery disease, blockages, or other cardiac conditions.
Treatment Planning: If any issues are detected, the healthcare provider discusses a customised plan. This may involve lifestyle modifications, medications or interventional procedures.
Continuous Observation: A plan for ongoing monitoring and follow-up is established. This takes into account the patient's specific health needs and any detected cardiovascular conditions.
Interpreting a CT coronary angiography report involves understanding the detailed information provided by the imaging study. Here are key aspects:
Coronary Artery Assessment: Evaluate the presence of atherosclerosis or plaque buildup in the coronary arteries. It also Identifies the degree of stenosis (narrowing), indicating the severity of blockages.
Calcium Scoring: Assess the calcium score CT coronary angiography to quantify the amount of calcified plaque in the coronary arteries.
Vessel Anatomy: Examine anomalies, irregularities, or aneurysms.
Plaque Characteristics: Consider the nature of the detected plaque. This includes composition (calcified, non-calcified, or mixed), which may impact the risk of future cardiovascular events.
Below is a simplified table outlining normal versus abnormal interpretations of a CT coronary angiography test.
Aspect of CTCA Interpretation | Normal Findings | Abnormal Findings |
Coronary Arteries | Clear, no plaque or stenosis. | Presence of atherosclerosis, plaque, or significant stenosis. |
Calcium Scoring | Low calcium score, indicating minimal calcified plaque | High calcium score, suggesting a higher burden of calcified plaque |
Vessel Anatomy | Absence of anomalies | Anomalies, or aneurysms |
Plaque Characteristics | Minimal or non-significant plaque | Characteristics such as calcified, non-calcified, or mixed plaque |
Extracardiac Findings | No major extracardiac findings. | Incidental findings like lung nodules or other abnormalities |
Overall Impression | No considerable coronary artery disease, CT angiography normal report. | Presence of notable coronary artery disease or other cardiac abnormalities. |
While CT coronary angiography is generally considered safe, it is essential to be aware of potential risks and complications. Here are major points to consider:
Radiation Exposure: This may carry a small risk of cancer. It can particularly happen in cases when individuals are undergoing multiple imaging studies. However, modern CT scanners often use dose-reduction techniques to minimise the danger.
Allergic Reactions: Some patients may experience a reaction to the contrast dye injected during the procedure. This can range from a mild immune response like a rash to severe, life-threatening anaphylaxis.
Claustrophobia: The need to lie still in an enclosed space during the CT scan may cause discomfort and anxiety in some individuals.
False Negatives: Despite its high accuracy, CTCA may occasionally produce false-negative results. A significant coronary artery disease might get missed, especially in the presence of heavily calcified or motion-distorted vessels.
While CT coronary angiography is generally considered safe, there are situations where it's important to consult a qualified professional. Signs to seek medical attention include:
Allergic reactions (rash, itching, or more) after contrast dye injection.
Severe chest pain or discomfort.
