India, Sept. 27 -- Heart disease can develop silently, without obvious symptoms in its early stages. Identifying people at increased risk before a major cardiac event is, therefore, an important part of preventive cardiology. Cardiac Computed Tomography (CT) is one of the modern imaging techniques that can help doctors assess coronary artery disease in appropriately selected patients. One important test is the Coronary Artery Calcium (CAC) scan, which detects calcium deposits in the walls of the coronary arteries. The resulting calcium score provides additional information about cardiovascular risk and can help doctors decide whether preventive treatment may be appropriate, particularly when a person's overall risk is uncertain. Another advanced investigation is the Coronary CT Angiography (CCTA). It provides detailed images of the coronary arteries and can identify plaque and narrowing without conventional invasive angiography. CCTA may be particularly useful in patients with symptoms suggestive of coronary artery disease (CAD) when routine tests, such as an echocardiogram (ECHO) or Treadmill Test (TMT), do not show abnormalities. It may also be considered in selected individuals with a strong family history of Coronary Artery Disease (CAD), particularly when there are additional cardiovascular risk factors. However, cardiac CT is not a routine screening test for everyone. The decision depends on factors such as age, symptoms, family history, diabetes, blood pressure, cholesterol, smoking history and overall cardiovascular risk. Used appropriately, cardiac CT can provide valuable information to support timely diagnosis, risk assessment and preventive care....
