Nuclear Stress Test Can You Be Around Babies

What is a nuclear stress test?

This test combines a typical stress test (treadmill, bicycle, persantin, dobutamine) with a nuclear scan component.

A nuclear stress exam measures claret flow to your middle musculus both at rest and during stress on the center. It is performed similar to a routine exercise stress test, simply provides images that can show areas of depression blood flow through the center and areas of damaged centre musculus.

A nuclear stress test usually involves taking two sets of images of your heart — i set during an exercise stress test while you're exercising on a treadmill or stationary bike, or with medication that stresses your centre, and another while you're at rest. A nuclear stress test is used to gather data about how well your eye works during physical activity and at rest.

You lot may be given a nuclear stress test if your doctor suspects you have coronary artery disease or another heart problem, or if an practise stress test alone wasn't plenty to pinpoint the crusade of symptoms like chest pain or shortness of breath. A nuclear stress exam may as well be recommended in lodge to guide your treatment if y'all've already been diagnosed with a heart status.

Why is a nuclear stress examination washed?

Your doc may recommend a nuclear stress test to:

• Diagnose coronary artery affliction. Your coronary arteries are the major claret vessels that supply your center with blood, oxygen and nutrients. Coronary artery disease is a condition that develops when these arteries become damaged or diseased — usually due to a buildup of deposits called plaques. If you have symptoms, such every bit shortness of breath or chest pains, a nuclear stress test can assistance determine if they are related to coronary artery disease.
• Look at the size and shape of your middle. The images from a nuclear stress test can bear witness your doctor if your center is enlarged and tin mensurate the pumping part (ejection fraction) of your heart.
• Guide treatment of eye disorders. If you've already been diagnosed with coronary artery disease, arrhythmia or some other eye condition, a nuclear stress test can help your md find out how well handling is working to save your symptoms. Information technology may also exist used to help constitute the right handling plan for yous by determining how much exercise your eye can handle.

What are the risks of a nuclear stress examination?

A nuclear stress test is generally safe and complications are rare. Simply, every bit with any medical procedure, it does deport a hazard of complications.

Potential complications include:

• Allergic reaction. Information technology's possible you could exist allergic to the radioactive dye that's injected into a vein in your hand or arm during a nuclear stress test.
• Low claret pressure. Exercise can result in low blood pressure level that makes you feel dizzy or faint. It usually goes away when you stop exercising.
• Abnormal heart rhythms (arrhythmias). Arrhythmias brought on by an exercise stress test unremarkably go away presently subsequently you finish exercising.
• Middle set on (myocardial infarction). Although very rare, information technology's possible that a nuclear stress test could crusade a heart set on.
• Flushing sensation or chest pain. These symptoms can occur when you are given a medication to stress your centre if you 're unable to practice fairly. These symptoms are usually brief, only tell your doctor if you experience them.

Preparing for a nuclear stress examination

You may be asked not to eat, drink or fume for ii hours before a nuclear stress test. You tin accept your medications every bit usual, unless your doctor tells you not to.

If you use an inhaler for asthma or other breathing problems, bring it with you lot to the exam. Make sure your doctor and the health intendance team fellow member monitoring your stress test know that you use an inhaler.

Wear or bring comfortable clothes and walking shoes with you lot to the exercise stress test.

Performing a nuclear stress test

When yous arrive for your nuclear stress test, your doctor asks yous nearly your medical history and how often you typically exercise. This helps determine the amount of do that'due south appropriate for you during the stress examination.

During a nuclear stress exam
Before you start the exam, a member of your health care team places sticky patches (electrodes) on your chest, legs and arms. The electrodes are continued past wires to an electrocardiogram (ECG or EKG) car. The electrocardiogram records the electrical signals that trigger your heartbeats. A blood force per unit area cuff is placed on your arm to bank check your blood force per unit area during the test.

If you're unable to practise, you may be injected with a medication that increases blood menses to your heart muscle — simulating do — for the exam.

You and then begin walking on the treadmill or pedaling the stationary bike slowly. Equally the exam progresses, the speed and incline of the treadmill increases. A railing is provided on the treadmill that you tin can use for balance, but don't hang on to information technology, as that may skew the results of the exam. On a stationary bike, the resistance increases equally the exam progresses, making information technology harder to pedal.

The length of the test depends on your physical fitness and symptoms. The goal is to have your heart work hard for almost eight to 12 minutes, in order to thoroughly monitor its part. You go on exercising until your heart rate has reached a set target, or until you develop symptoms that don't let y'all to continue or alarm signs detected by those monitoring your examination, including:

• Moderate to astringent breast pain
• Astringent shortness of breath
• Abnormally high or depression blood pressure
• An aberrant centre rhythm
• Dizziness

You may finish the examination at whatever time if you are also uncomfortable to go along exercising.

Injection of dye

Once y'all've reached your maximum level of exercise, a radioactive dye chosen thallium or sestamibi (Cardiolite) is injected into your bloodstream through an intravenous (IV) line, usually in your hand or arm. This substance mixes with your blood and travels to your eye. A special scanner similar to an 10-ray car — which detects the radioactive material in your middle — creates images of your heart muscle. Inadequate claret flow to any part of your centre will show up equally a low-cal spot on the images — considering not as much of the radioactive dye is getting at that place.

Afterward exercising, you'll exist asked to rest for ii to four hours. During this fourth dimension, yous shouldn't swallow or drink anything, or do whatever strenuous activities. After this fourth dimension, y'all'll take a second set of images taken of your eye while you lie on an test table. Again, a technician will inject radioactive dye through an Four and will have images of your heart. This 2nd set of images will let your doctor compare the blood menstruation through your heart while you're exercising and at residue.

Afterwards a nuclear stress test
When your nuclear stress test is complete, you may return to your normal activities for the residuum of the 24-hour interval.

Results of the nuclear stress test

Your md will discuss the results of your nuclear stress exam with you. Your results could show:

• Normal blood flow during exercise and rest. If the data gathered during your nuclear stress test shows your heart function to exist normal both during exercise and rest, it'south unlikely y'all have coronary avenue disease. You may not need any further tests.
• Normal claret flow during residue, but non exercise. This means that your centre muscle isn't receiving plenty blood when you're exercising or doing other strenuous action. This may hateful you have 1 or more blocked arteries (coronary artery disease).
• Depression blood period during remainder and exercise. This means your heart isn't getting enough blood flow at all times, and yous may need to beginning treatment for coronary artery affliction or another middle condition that might limit blood flow through your heart.
• Lack of radioactive dye in parts of your heart. Areas of your heart that don't show the radioactive dye are areas that have damaged tissue (scar tissue) from a heart assail.

If your test results show y'all don't have enough blood catamenia through your heart, y'all may need to undergo coronary angiography — a exam to wait directly at the claret vessels supplying your middle. If you have astringent blockages y'all may need a coronary intervention (balloon angioplasty and stent placement) or open up heart surgery (coronary artery bypass).

Note: We exercise not perform the nuclear stress test in our office, it is performed in hospital radiology departments like MIA Radiology at Peninsula and Beleura Private Hospitals, and Frankston Hospital.
