Chest CT examination can find coronary artery atherosclerosis, pericardial effusion, constrictive pericarditis and so on. 1. Coronary artery atherosclerosis: CT scan can find coronary artery calcification. 2. Pericardial effusion: Chest CT scan of pericardial effusion can show enlarged pericardial cavity and large amount of fluid in the pericardial cavity. 3. Constrictive pericarditis: CT scan can see irregular thickening of the pericardium, high-density calcified shadows and so on. Although chest CT scan can see cardiac abnormalities, the first choice of examination for heart disease is cardiac ultrasound. When chest CT scan finds abnormal heart shape or discomfort, you should consult a doctor in time, and choose the appropriate examination and treatment according to your condition under the guidance of the doctor.
