Coronary calcium scan is a non-invasive diagnostic method that detects calcification on the coronary artery wall, thereby helping to predict the risk of death in patients with asymptomatic coronary artery disease before 15 five.
1. What is a coronary calcium scan?
Coronary artery calcification is a technique that uses a computerized tomography (CT scanner) to check for the accumulation of calcium plaque in the coronary arteries.
Through the coronary calcium scan technique combined with other information related to the patient's health, the doctor can calculate the risk of coronary artery disease or myocardial infarction.
In addition, the coronary calcium scan is also used to check for people with early-stage heart disease and determine its severity.
2. What is coronary artery disease?
Coronary artery disease occurs when plaque builds up in the arteries. Fat, cholesterol and calcium are the ingredients that make up those plaques.
According to research, the deposition of calcium in the coronary artery wall will lead to atherosclerosis, they account for 20% of the area of atherosclerotic plaque.
3. When is a coronary calcium scan indicated?

According to the classification of factors that increase the risk of cardiovascular disease at 10 years, if you are classified as a moderate risk factor (ie, the probability of having a heart attack in the next 10 years is between 10 and 20 years). %), the patient is assigned a coronary calcium scan to predict the possibility of myocardial infarction.
Coronary calcium scanning is only beneficial if the patient is at moderate risk or has unexplained chest pain. In addition, this technique is also indicated in cases where other test results do not determine whether treatment should be treated to reduce the risk of coronary heart disease or not.
However, coronary calcium scanning is not recommended for pregnant women or for routine check-ups for patients with coronary artery disease, but only for certain cases, because during the procedure. may increase the risk of radiation exposure and cancer development.
4. Techniques for performing coronary calcium scan indications
It takes about 30 minutes to perform a coronary calcium scan. Patients should not smoke, eat or drink anything containing caffeine for a few hours before the test. The following is the procedure for performing a coronary calcium scan:
A coronary calcium scan is performed by a radiologist. Through the images taken, the results will be analyzed by a radiologist. Use the CT scanner to move around the body. The table will move to take pictures. The technician may ask the patient to hold their breath for about 20 seconds while taking pictures of the heart. Electrodes are placed on the chest to connect to an ECG machine to record the electrical activity of the heart. The ECG records the heart's activity while the patient is at rest. If the patient's heart rate falls to about 90 beats/minute or higher, medication can be used to slow the heart rate. In summary, coronary calcium scanning is a technique to help check the accumulation of calcium plaque in the coronary arteries. To get accurate results, as soon as you notice the symptoms of chest pain, shortness of breath, etc., the patient needs to go to a reputable hospital for examination and treatment.
