This will help the physician to monitor your blood sugar levels as you exercise.

    During test day, wear loose, comfortable clothing, and shoes. The physician will also give you further instructions. Skip a meal; this enables you to exercise longer and safely compared to when you are full. You should also be aware of which pills to take. Some medicines low down your heart rate, so consult your doctor for further advice. Avoid caffeine and over-the-counter medications that contain caffeine for at least 24 hours. Although daily exercises are not necessary, you should at least have a daily activity.

    During the Test

    The first step includes taking the first set of pictures. The physician starts an IV line in your arm then injects you with Myoview or another similar drug. After the drug takes effect, the first set of pictures of your heart are taken as you lie under a nuclear imaging scanner. This medication showcases areas in your heart that are utilizing oxygen.

    If your heart is healthy, the highlighted part looks like a horseshoe. The goal is for rest and stress images to look the same even if they show defects. The physician will also look for problems that might be visible before taking the test. If there are problems, you might be referred to a cardiologist.

    The next step is for you to take the stress test, which is the treadmill exercise test. You are required to walk on a treadmill. The machine’s speed increases steadily until the physician decides you need to stop or you reach your target heart rate. Once this is achieved, the specialist injects you with Myoview again. You have to stay on the treadmill for at least a minute for the medication to circulate. Another type of stress test has your heart stressed by injecting another medication, which allows you to skip the treadmill if you have a condition that requires you to do so. The physician monitors your heart rate as it gets back to normalcy.

    When the exercise part is done, you are required to eat and then get back to your physician after 2 hours. After this, you will have a second set of pictures taken. There is no restriction on what you eat before this set of pictures.

It might also show no dye on some portions on your heart, which indicates tissue damage. The test might also show inadequate blood flow when exercising and resting which, might indicate that you have coronary heart disease. The results might display normal blood flow when resting, but not as you exercise, which might be an indication of a blocked artery.

    If your tests are normal, you will not require further tests. If the results show that you have a blocked artery, further tests are conducted, or you might require surgery. This might include a balloon angioplasty, which a minimally invasive surgery; it involves cardiac catheterization to open your blocked arteries. This procedure might take 30 minutes to 2 hours, but it usually lasts for an hour. Other surgery interventions include stent placement, which is a tiny tube placed into a blocked artery to keep it open. A coronary artery bypass directs blood around a blocked artery.
