Pain Management Forum - Persantine Cardiolite Stress Test. Is It a Hard Test?

i have severe asthma and the cardilogist cannot give me the normal pulmonary stress test. I will get the persantine cardiolite stress test.

I was put on the "ct" machine with no pain meds in me. After a few minutes of the mechanism pushing me left to right, with sharp stops...My lower back area said that was enough. I am unclear exactly what happened, but I think the lady was giving up on getting the last photos of me and tolk me to roll over on my right side. As I rolled over on my right elbow...To raise up...The nurse grabbed my left hand and jerked me upright. Pretty intense pain...I woke up on the floor with 3 nurses trying to get me in the wheelchair. As I was sitting down on the front edge of the wheelchair, the nurse sort of put her finger in my chest and pushed me backwards. Wrong thing to do to me when I am hurting like that. Then I woke up with several people trying to get me on a gurney. I called my wife after they left me in a side room. She brought my demerol and avinza. I had not had a pill that day. Fasting.

Anyway, my wife got there and got me some water. I took the meds and starting feeling better. Long day.

Have any of you had this test? I will let you know if it hurts.

Thanks for any ideas.......Dave

Addition heart images will be required on another day. The radiology department will discuss this with you on the day of your test. Please allow three hours for the additional session.
What is a persantine cardiolite stress test?

A persantine cardiolite stress test helps diagnose coronary artery disease or identifies areas of the heart that lack an adequate blood supply due to narrowed or blocked coronary arteries. Coronary arteries are located on the outside of the heart and bring oxygen rich blood to the heart muscle. Your physician has determined that you are unable to exercise adequately on a treadmill or a stationary bicycle. Persantine (diprydamole) is a medication that dilates the coronary arteries to produce an effect similar to what happens when you exercise. Persantine and cardiolite is infused (given over 4 minutes) through a vein in the arm while resting. Cardiolite (a radioactive tracer) travels in the blood stream to the heart where it is picked up by the heart muscle. Areas of the heart muscle that lack an adequate blood supply pick up the tracer very slowly or not at all. The tracer emits a small amount of radioactivity that will be detected by a special scanning camera one hour later in radiology. This session will last about 30 minutes.

If the area of the heart muscle receives less blood supply than the rest of the heart muscle because of narrowed or blocked coronary arteries, the scan will show less tracer in that area of the heart muscle. The scan helps the physician determine areas of the heart muscle that do not receive enough blood supply.

What happens during the test?

Several electrodes (adhesive patches) will be placed on your chest to record heart activity during the test. While lying on a bed, persantine is given through a vein in your arm for 4 minutes. You will be instructed to report any symptoms such as chest discomfort, headache, dizziness, nausea, facial flushing and shortness of breath. The radioactive tracer is given a few minutes later through the same vein. You will continue to rest for an additional 5 to 10 minutes while your blood pressure and electrocardiogram are monitored. After eating you will be asked to report to radiology an hour later for the scanning session, which last about 30 minutes.

Is the persantine cardiolite stress test safe?

The radiation exposure during the test is small (less than a chest x-ray), and the doses are safe. The scanning camera detects the cardiolite; it does not take x-rays. However, if you are pregnant, suspect you may be or are a nursing mother. Discuss the test with your doctor. A small amount of risk exists with any test that stresses the heart. Possible rare complications include abnormal heart rhythm, low blood pressure or heart attack. Experienced personnel are available to handle any emergency.
