What is a Cardiac CT Scan?
A cardiac CT scan is a type of computed tomography (CT) that uses X-rays to capture detailed cross-sectional images of the heart and blood vessels. These cross-sectional images can be reconstructed into 3D images to assess the structure of the heart and the degree of narrowing in blood vessels. Coronary artery CT, which specifically examines the coronary arteries that supply blood to the heart, is included in cardiac CT.
When Should You Get a Cardiac CT Scan?
A cardiac CT scan is typically recommended when abnormalities in the coronary arteries, aorta, or heart structure and function are suspected. Most commonly, it is used to evaluate the presence and severity of coronary artery narrowing in patients experiencing chest pain that feels like squeezing. It is also used to assess risks before coronary artery procedures or surgeries.
What Happens If Coronary Artery Narrowing is Detected?
If a cardiac CT scan reveals coronary artery narrowing, treatment will depend on the presence of symptoms and the degree of narrowing. Lifestyle changes such as quitting smoking, reducing alcohol consumption, adopting a low-sodium diet, and exercising regularly are crucial to preventing the progression of coronary artery disease. Additionally, medications to lower blood pressure, reduce bad cholesterol, or prevent blood clots may be prescribed.
Can Coronary Artery Disease Exist Without Symptoms?
Yes, coronary artery disease can be present even without noticeable symptoms. Adults with high blood pressure, diabetes, high cholesterol, or obesity are at higher risk. Early detection and treatment of coronary artery disease in these individuals are critical to preventing serious complications.
What is a Calcium Scoring CT?
A calcium scoring CT measures the amount of calcium buildup in the coronary arteries, which helps determine the risk of developing coronary artery disease. This test can be done without the use of contrast agents. Based on the degree of calcification in the coronary arteries, a calcium score is calculated. Higher scores indicate a greater risk of coronary artery disease and may warrant additional tests.
Can You Get a Cardiac CT Scan During a Health Checkup?
Yes, many hospitals equipped with CT machines offer cardiac CT and calcium scoring as optional health checkup services. Many facilities provide specialized cardiovascular screenings or advanced checkups that include cardiac CT. If you’re concerned about your heart health, consider adding a cardiac CT scan to your health checkup!
