What to expect
Before the stress portion of the heart test, a small intravenous (IV) line will be started in a vein in your arm. The IV will allow us to inject the Regadenoson and Cardiolite into the bloodstream at the appropriate time. A blood pressure cuff will be placed around your other arm to monitor your blood pressure during the test. Electrodes will be placed on your chest to monitor your electrocardiogram throughout the test.
Regadenoson and Cardiolite will be injected while we monitor your blood pressure and electrocardiogram.
Afterwards, we will ask you to eat a "fatty" meal to help clear any medication from your stomach and colon as this would interfere with the imaging.
Approximately one hour later the pictures will be taken with a special camera.
You will lie on your back with your arms above your head while the camera takes pictures of the blood flow to your heart from many different angles. The pictures are stored in digital form on a special computer.
On a separate day, the resting portion of the exam will be performed.
Cardiolite will be injected directly into a vein while you are at rest. After you have been injected, you will need to eat a fatty meal.
Approximately one hour later, a set of pictures of the blood flow to your heart will be recorded.
After you leave the laboratory we will perform special computer processing of both sets of pictures to compare the blood flow pattern to your heart at stress and at rest.
