The document discusses three cardiac diagnostic tests: 1. Cardiac enzymes tests measure levels of heart muscle enzymes in the blood to detect heart attacks or injury to the heart. 2. Doppler ultrasonography uses sound waves to produce images and measure blood flow velocities to diagnose heart valve problems, arterial narrowing, blood clots, and more. 3. Cardiac scans, also known as heart scans or coronary calcium scans, use pictures of the heart arteries to look for calcium deposits that increase heart attack risk. The coronary calcium score from this test can indicate heart disease risk.

6. Determine whether you are having a heart attack or a threatened heart attack.

7. Check for injury to the heart after bypass surgery.

8. . Determine if a procedure, such as percutaneous coronary intervention (PCI), or a medicine to dissolve the blockage (thrombolytic medicine) has successfully restored blood flow through a blocked coronary artery.

10. It measure velocity of blood moving through blood vessels to look for blood cots or deep vein thromboses.

11. It is frequently used in cardiac and vascular scanning to evaluate blood flow and diagnose abnormalities in flow.

12. Cardiac applications include the detection of heart valve problems, the determination of arterial vessel narrowing (stenosis) or blockage, the diagnosis of congenital cardiac defects, and the evaluation of damage following myocardial infarction (heart attack).

13. Vascular applications include the work-up of stroke patients, the assessment of blood flow in the major abdominal arteries, and the evaluation of vessels in the arms, legs, and neck

15. cardiac scans, also known as coronary calcium scans, provide pictures of your heart's arteries (coronary arteries). Doctors use heart scans to look for calcium deposits in the coronary arteries that can narrow your arteries and increase your heart attack risk. The result of this test is often called a coronary calcium score.

16. Cardiac scans may show that you have a higher risk of having a heart attack or other problems before you have any obvious symptoms of heart disease.
