Nuclear Stress Myocardial Perfusion Imaging

Echocardiography is a test that uses ultrasound to make a picture of your heart. Ultrasound uses sound waves, or echoes, to make the picture. This test is used to determine if you have enough blood flowing to your heart and how well your heart is pumping.

Pictures of your heart will be taken before and after you exercise.

The purposes of this test are to:

• Diagnose if you have coronary artery disease or are at risk of getting coronary artery disease
• Determine how likely it is that your condition will get worse
