What can a stress test tell you?
A stress test is used to help diagnose and evaluate heart problems such as ischemic heart disease, heart valve disease, or heart failure.

In a very controlled situation, the heart is stressed using either exercise on a treadmill or a chemical injection, depending on the status of the individual getting the test. Heart rate, rhythm, and blood pressure are continuously monitored throughout the entire exam.
What happens during a nuclear stress test without exercise?
In a chemical stress test, the patient receives medications that either speed up the heart rate or dilate the arteries. The body responds in a similar way it would to exercise. A radionuclide is injected into the patient’s arm or hand while resting.
What are the warning signs of clogged arteries?
Do clogged arteries cause any symptoms?Chest pain.Shortness of breath.Heart palpitations.Weakness or dizziness.Nausea.Sweating.
What happens if your stress test is abnormal?
An abnormal result in both phases of your stress test is an indication that your heart’s blood flow is poor, regardless of your exertion level. The restricted blood flow suggests significant coronary artery disease.
What is the difference between a nuclear stress test and a stress test?
A nuclear stress test is very similar to a regular stress test, except it also includes imaging of your heart and radioactive dye in your veins. This test takes pictures of blood flow to your heart by first injecting radioactive dye (radiopharmaceutical or radiotracer) into your bloodstream before the images are taken.
How many types of stress tests are there?
There are three main types of stress tests: exercise stress tests, nuclear stress tests, and stress echocardiograms.
How do you pass a stress test?

What type of stress test is best?
A nuclear stress test is one of several types of stress tests that may be performed alone or in combination. Compared with an exercise stress test, a nuclear stress test can help better determine your risk of a heart attack or other cardiac event if your doctor knows or suspects that you have coronary artery disease.

Is a CT scan better than a stress test?
Results of a head-to-head comparison study led by Johns Hopkins researchers show that noninvasive CT scans of the heart’s vessels are far better at spotting clogged arteries that can trigger a heart attack than the commonly prescribed exercise stress that most patients with chest pain undergo.
What drug is used for stress test?
Adenosine, dipyridamole (Persantine), and dobutamine are the most widely available pharmacologic agents for stress testing. Regadenoson, an adenosine analog, has a longer half-life than adenosine, and therefore a bolus versus continuous administration. Adenosine, dipyridamole, and regadenosine are cardiac vasodilators.
Does a stress test show blockages?
Stress tests can detect when arteries have 70 percent or more blockage. This severe narrowing is what causes the severe chest pain called angina. But normal results from a stress test do not rule out the possibility of a future heart attack. This is because a plaque can still rupture, form clots and block an artery.
