Our state-of-the-art Nuclear Laboratory performs several types of cardiovascular diagnostic tests. With the use of hi-tech computers, we can analyze relative blood flow and global function of the heart muscle. A nuclear stress test is similar to an exercise stress test, but it is more accurate since it uses SPECT or PET scans in addition to a traditional exercise stress test. It allows your doctor to look at your heart’s reaction to stress, either through exercise or with medications. A clearer picture of heart health is given, but the use of radioactive substances during the test prevent cardiologists from using this as a replacement to exercise stress tests. A radioactive substance, known as an isotope, is injected into the blood, where it travels to the heart. By using a special monitor, your doctor can create a picture of your heart. This test is especially useful if you have suffered from a heart attack, have a blood clot, or have symptoms of coronary artery disease. You may have a light breakfast prior to the stress test. For twelve hours prior to the stress test you should not have any caffeinated foods or drinks including coffee, tea, decaffeinated coffee or tea, chocolate in any form and all colas/fountain drinks/sodas. You will be asked by one of the office staff to hold certain medications prior to the test. Therefore, please BRING THE PILLS WITH YOU THAT YOU DID NOT TAKE SO YOU CAN TAKE THEM AFTER THE TEST. This is particularly important if you are on diabetic or heart medications. If you have asthma, emphysema, chronic bronchitis or chronic obstructive lung disease you must inform your doctor several days before the test because you may not be a suitable candidate for this test. If you are pregnant or breast-feeding, please check with your doctor.
