Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read more

How is a persantine sestamibi stress test performed?

How is a persantine sestamibi stress test performed?

pharmacologic stress: Often we use other agents but Persantine is injected and the patient is either imaged soon after or after a little exercise, after the Persantine administration, sestamibi is injected to allow the imaging. ...Read more

What is the persantine sestamibi stress test?

What is the persantine sestamibi stress test?

See below.: This is a chemical stress test of blood flow to the heart muscle. It is used to evaluate patients who are unable to exercise. Pictures of blood flow are obtained before and after the stress. Post stress abnormalities may indicate narrowings of the coronary arteries which impede blood flow and may be a cause of chest pain. Abnormalities of flow before stress may indicate previous damage. ...Read more

Why are dobutamine-induced stress echocardiogram used?

Why are dobutamine-induced stress echocardiogram used?

Better information: A stress echo allows you to view heart function under a stressor. The stress is an elevation in heart rate and produced by the dobutamine. It allows us to see if your blood flow in the coronary ateries can meet demand. Is like economics , supply vs demand. ...Read more

Nuclear cardiology stress test--how much radiaiton?

Nuclear cardiology stress test--how much radiaiton?

Radiation exposure: There most certainly is radiation exposure with nuclear cardiology stress testing whether it is with thallium, sestamibi, or any of the pet imaging agents. The exposure is minimal but real and the risk vs. Benefit to the patient needs to be considered before ordering the study. Pregnant women should not have these studies and young women can have a very small but increased risk of breast cancer. ...Read more

Is routine dipyridamole thallium scintigraphy still used by doctors?

Is routine dipyridamole thallium scintigraphy still used by doctors?

Yes: In some hospitals it is. But Lexiscan (regadenson) has largely replaced Dipyridamole in most labs. Thallium is also still used sometimes, especially to evaluate hibernatining myocardium, but newer radionuclides have largely replaced it for routine testing. ...Read more

Whats safer: coronary angiogram or CT angiogram?

Whats safer: coronary angiogram or CT angiogram?

Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read more

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage.Answer depends on information physician needs and insurance. ...Read more

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

NO!!!!: Caffeine should not be ingested prior to pharmacologic cardiac stress since it can interfere with the results. Stopping caffeine ingestion for at least 24 hours prior to pharmacologic stress should be sufficient. If caffeine is ingested and pharmacologic stress is performed, this can cause false negative results. If you have taken caffeine, stress may be rescheduled or switched to dobutamine. ...Read more

What is a nuclear myocardial perfusion study?

What is a nuclear myocardial perfusion study?

Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest . These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery. ...Read more

What is myocardial perfusion scintigraphy?

What is myocardial perfusion scintigraphy?

Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read more

No: Angina is a clinical symptom. The angiogram r cardiac ct are both imaging studies. We can look at imaging studies and suggest that there is narrowing of the coronary arteries which may cause angina. ...Read more

What is adrenosine nuclear test preparation?

What is adrenosine nuclear test preparation?

No caffeine 24 hrs: Among other things to withhold, caffeine is probably the most important as it negates the effect of adenosine, preventing any stress. Other common things are don't eat for at least 4 hours prior to the test, no chocolate, stop some medications. Call the testing office for their specific protocol. ...Read more
