When is a nuclear stress test contraindicated?
Contraindications: Adenosine is contraindicated in patients with reactive airway disease with significant wheezing. Patients with a history of advanced conduction abnormalities, including 2nd or 3rd-degree atrioventricular block in the absence of a permanent pacemaker.
Which of the following situations would be considered an absolute contraindication for performing adenosine pharmacological stress testing?
Active wheezing and bronchospasm are clinical situations for which adenosine use is considered an absolute contraindication (3,6–9).
What are three absolute contraindications and three relative contraindications to exercise testing?
Answer. Absolute contraindications include unstable angina, aortic stenosis, uncontrolled hypertension, uncontrolled asthma, hypoxemia (SaO2<85% at rest), and febrile illness. Relative contraindications include hypertension, cardiac disease, epilepsy, and locomotor disorder (inability to exercise).
What is relative contraindication?
Relative contraindication means that caution should be used when two drugs or procedures are used together. (It is acceptable to do so if the benefits outweigh the risk.) Absolute contraindication means that event or substance could cause a life-threatening situation.

What are the risks of a pharmacological stress test? A pharmacologic stress test may cause you to feel dizzy, lightheaded, or weak. You may have throbbing or extra heartbeats, chest pain, or a heart attack.
What is pharmacological stress testing?
A pharmacological nuclear stress test is a diagnostic test used to evaluate blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart.

What should you not do before a cardiac stress test?
You may be asked not to eat, drink or smoke for a period of time before a stress test. You may need to avoid caffeine the day before and the day of the test. Ask your doctor if it’s safe for you to continue taking all of your prescription and over-the-counter medications before the test.
What pharmacological agent is best suited for stress cardiac ultrasound?
Adenosine, dipyridamole (Persantine), and dobutamine are the most widely available pharmacologic agents for stress testing.

Which of the following are contraindications for performing an exercise test?
Relative contraindications for exercise ECG
- Severe hypertension (systolic blood pressure >200 mmHg or diastolic blood pressure >110 mmHg).
- Left main coronary artery stenosis.
- Severe electrolyte imbalance.
- Severe hyperthyroidism.
- Moderate to severe aortic stenosis.
What are the risks of a chemical stress test?
It causes blood vessels of the heart and other areas of the body to dilate. You may experience side effects such as shortness of breath, chest pain, headache, nausea, flushing, and throat or jaw pain.
When is pharmacological stress test used?
Your doctor may use the test to: Diagnose the cause of chest pain, shortness of breath and weakness. Diagnose or monitor a heart condition, such as heart disease or arrhythmias (abnormal heart rhythm). Evaluate your risk for a cardiac event (such as a heart attack).
Should I take my blood pressure medication before a stress test?

Last updated on Oct 4, 2021. What is pharmacologic stress testing? Pharmacologic stress testing uses medicine to make the heart work just as it does when you exercise.
What is the preferred stress modality for pharmacologic stress testing?
Although patients may require pharmacologic stress testing because they are unable to perform adequate physical exercise, dynamic exercise on treadmill or bicycle remains the preferred stress modality. In our nuclear stress laboratory, the percentage of myocardial perfusion studies performed with exercise has remained approximately 50% since 2004.
