coronary CTA guidelines

Coronary CTA (Computed Tomography Angiography) is a non-invasive imaging test that uses CT scans to visualize the coronary arteries and assess for blockages or narrowing that could cause heart problems. Guidelines recommend its use primarily for intermediate-risk patients with unclear symptoms, or those with an intermediate likelihood of coronary artery disease. It's valuable for detecting early signs of disease, guiding treatment decisions, and avoiding unnecessary invasive procedures. Factors like kidney health and allergies to contrast dye are considered before the test. Overall, CTA is a useful tool for accurate diagnosis and risk assessment of coronary artery disease in appropriate patients.
