Question

The coronary artery disease (CAD) can be determined by:

• A. Cardiac catheterization
• B. Electrocardiogram
• C. Treadmill stress test
• D. All the above

Answer 1

The correct option is D All the above

Coronary arteries are the arteries that supply blood to the heart and surround the heart. The blockage or narrowing of these arteries is called coronary artery disease or atherosclerosis. The coronary artery disease can be detected by cardiac catheterization, electrocardiogram and treadmill stress test.

Cardiac catheterisation is a method to determine any disease in the heart muscle, valves or coronary arteries.

Treadmill test is a cardiovascular stress test that uses electrocardiography and blood pressure monitoring. This test checks whether the coronary arteries are functioning normally.

Electrocardiogram is a simple test that measures our heart’s electrical activity. Heart problems like CAD affect the electrical activity of our heart, so that abnormality in the electrical activity of the heart can be assessed by this test.
