Cardio CT, Coronary CT scan
Cardio CT scans are used to examine the coronary arteries, either as a preventive measure or to detect many unclear cardiological symptoms.
The purpose of a coronary CT scan is to
To detect atherosclerosis in the coronary arteries at an early stage with high accuracy, allowing the timely initiation of targeted therapy to prevent heart attacks.
Coronary artery disease affects many people and in many cases the first sign of the disease is acute myocardial infarction or sudden cardiac death. Unfortunately, the widely used exercise ECG in our country does not reliably predict these abnormalities, but coronary CT scanning is an excellent tool for imaging and assessing fat and calcium-containing plaques deposited in the inner walls of blood vessels. These deposits cause vasoconstriction and consequently a reduction in blood supply to the myocardium, a lack of oxygen and, in severe cases, its death. Because deposits can develop unnoticed for decades, even without warning symptoms, early detection can increase the chance of survival.
Before a coronary CT scan, we recommend a specialist cardiology examination, as it is only performed on the advice of a specialist.
Who is a Cardio CT scan recommended for?
The test is necessary if the patient
- has chest pain that has not been previously investigated
- a family history of myocardial infarction.
- patients at low to moderate cardiovascular risk
- in valve disease as part of pre-operative investigations
- as a periodic control test
Prerequisites for coronary CT scanning
The use of iodinated contrast media and compliance with the instructions below are essential for coronary CT scanning:
- If allergic to iodinated contrast material, the scan should not be performed
- renal function results within 2 weeks are required to allow for proper selection of the contrast agent
- discontinue oral anti-diabetic/antidiabetic medication 2 days before and after the test
- do not skip any other medicines
- do not eat for 4-6 hours before the test
- you can drink water, but not caffeine-containing drinks (coffee, green tea, energy drinks) because of their stimulating effect on the test
- do not exercise on the day of the test, avoid stress
If the patient has limited renal function and/or is sensitive to contrast media, their use should be avoided if appropriate. Therefore, a renal function laboratory test is recommended up to one week before the test. The specialist will decide whether to perform a native study with contrast or without it, taking into account the risks. The latter is less effective but free from the risk of contrast media.
