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

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

Can angio cardiac CT detect angina?

Can angio cardiac CT detect angina?

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 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

Define?accute anteroseptal myocardial infarction, atherosclerotic obstructive coronary artery disease, pulmonary edema, cardiogenic shock, hypokalemia

Here are some...: A 400-letter space is impossible to address many indicated subjects as questioned here. Why not type in the terms as keywords to search online? Thereby you surely gain a lot of pertinent information to feed your appetite of knowledge. Or you may just ask your doc who should be able to answer your questions to the point much easier. ...Read more

Would Cardiac stress perfusion scan MRA highlight Pulmonary Hypertension if this was present?

Would Cardiac stress perfusion scan MRA highlight Pulmonary Hypertension if this was present?

Probably not: A cardiac echo/Doppler study would show pulmonary HTN changes by viewing the right ventricular function , size and pressure. There are additonsl studies that can also be done. It is very important to know WHY you have Pulmonary HTN. If due chronic Pulmonary embolism it is a serious situation for which there exists very effective Rx. Other causes can also be treated. Consult your doc. ...Read more

What confirms myocardial infarction?

What confirms myocardial infarction?

Toponins,clinic,wall: Acute cardiogenic shock, .Ventricular arrythmias, infarct syndrome, flash pulmonary edema, wall motion abnormalities, syncope, presyncope, cardiac arrest, . It takes 4 hours for troponins to elevate after the infarct begins. That is why clinical symptoms dictate emergent coronary interventions. Troponins may still be normal within minutes of a life threatening myocardial infarct. ...Read more

Does a myocardial perfusion scan show blockage in the heart?

Does a myocardial perfusion scan show blockage in the heart?

Blood Perfusion: The angiogram shows anatomic blockage of coronary arteries. The myocardial perfusion scan shows blood flow to the heart. Blood flow can get past large blockages (shown on angiography) if there are enough small, collateral vessels present. ...Read more

My nuclear images suggest apical septal ischemia.

My nuclear images suggest apical septal ischemia.

Ischemia...: Most hearts have physiologic apical thinning which can sometimes be misinterpreted on nuclear stress test images. In addition, stress test images in patients with left bundle branch block can appear as septal ischemia if exercise stress is done rather than pharmacologic. The fact that both the apex and septum are involved in your case make it more likely to be real ischemia probably in lad. ...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

Mibi scan shows diffuse reversible ischemia in keeping with angina?

Mibi scan shows diffuse reversible ischemia in keeping with angina?

Heart disease: Angina means chest pain caused by the heart. This usually comes from clogged arteries. As the arteries initially clog, blood can still get around the blockage and is reversible. This can eventually progress to a worsening blockage where blood can't get around it. This usually results in what is known as a heart attack. Reversible is good but it's important to prevent it from getting worse. ...Read more

How does caffeine affect the results of thallium myocardial perfusion scan?

How does caffeine affect the results of thallium myocardial perfusion scan?

Not usually: Caffeine in the usual dietary dose won't affect an exercise stress test with thallium imaging, but if you ingest caffeine recently you cannot have a stress test with pharmacologic stress using Persantine (dipyridamole), Adenosine or Lexiscan because the caffeine interferes with the metabolism of those agents. ...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
