Examinations for Coronary Diseases
Electrocardiogram (ECG) records the electrical activity of your heart at rest. Performing it during exercise is called a stress test. Both tests show whether your heart is working properly when oxygen is reduced.
Exercise thallium test is also known as nuclear stress test. For the test, thallium, a radioactive substance, is administered into the blood and its retention by the heart is observed. It cannot retain the substance sufficiently due to a damaged or dead heart muscle or a narrowed vessel.
Echo cardiography,The heart's functioning and blood flow are monitored with sound waves. In coronary angiography, after the patient is sedated with a medication, a dye is injected into your bloodstream, while the doctor monitors your heart's arteries, valves, and blood flow live with an x-ray. It detects whether there is a blockage and its degree. This method is generally used to determine what kind of treatment should be applied.
Positron emission tomography (PET)By detecting the energy of certain elements in the body, it is determined that the heart muscle is alive and working, and whether the incoming blood is sufficient. It can be checked whether there is any.
Coronary angiography: It is a moving x-ray film in which your coronary vessels are examined with a camera. The procedure is performed in the catheterization laboratory. Your doctor inserts a thin, flexible catheter into one of the large arteries in your arm or leg and advances it to the aorta, where the coronary arteries originate. A dyed substance is injected into the coronary arteries through the catheter.
Meanwhile, the film taken can determine the stenosis in which areas of your coronary vessels.
