What is this test? CT Angiography (CTA) of the coronary arteries is a specialized imaging test that uses computed tomography combined with intravenous contrast dye to create highly detailed, three-dimensional images of the blood vessels supplying the heart muscle. This non-invasive procedure allows direct visualization of the coronary arteries, helping physicians assess blood flow and detect any narrowing, blockages, or abnormalities that could compromise heart function. What is it used for? * Detecting coronary artery disease (CAD), including the presence and severity of atherosclerotic plaques * Identifying stenosis (narrowing) or complete blockages that could lead to angina or heart attacks * Evaluating congenital anomalies or structural variations of coronary arteries * Assessing coronary arteries in patients with chest pain, especially when traditional tests are inconclusive * Guiding clinical decisions regarding further invasive procedures such as angioplasty or bypass surgery * Monitoring known coronary artery disease for progression or response to treatment Who should get this test? * Patients experiencing chest pain, shortness of breath, or other symptoms suggestive of coronary artery disease * Individuals with risk factors for heart disease, including hypertension, diabetes, high cholesterol, smoking, or family history of early cardiac events * Patients with abnormal results on stress tests or EKGs who require further anatomical assessment * Those unable or unwilling to undergo invasive coronary angiography but needing detailed coronary evaluation Preparation Required: * Patients should fast for at least 4-6 hours prior to the scan to reduce the risk of nausea during contrast injection * Administration of beta-blockers may be required to slow the heart rate, ensuring clearer images by reducing motion artifacts * Intravenous contrast dye is injected during the scan to enhance visibility of the coronary vessels; kidney function tests are typically performed beforehand to confirm safety * Avoid caffeine and certain medications as advised by your healthcare provider prior to the test How is the procedure performed? The patient lies on a CT table that slides into the scanner. Electrodes are attached to monitor heart rhythm during the scan. The scan usually takes 10 to 15 minutes. During the test, the contrast dye is injected through an IV, and multiple rapid X-ray images are captured synchronized with the heartbeat to generate detailed coronary artery images. Patients may be asked to hold their breath briefly to improve image quality. Risks & Safety: While the procedure is non-invasive, it involves exposure to ionizing radiation. The radiation dose is carefully managed to balance diagnostic quality and patient safety. Contrast dye injection carries a low risk of allergic reactions or kidney irritation, particularly in patients with pre-existing kidney issues. Overall, the benefits of accurate diagnosis and prevention of serious cardiac events outweigh these minimal risks. Results: A radiologist or cardiologist reviews the images to identify any arterial blockages, plaques, or abnormalities. The report provides a detailed assessment of coronary artery patency, plaque composition, and any signs of vascular disease, which helps guide appropriate treatment strategies. Short Statement: A non-invasive CT Angiography that produces detailed images of coronary arteries to detect blockages, plaques, or anomalies that can lead to heart attacks or angina, enabling timely and targeted heart care.
