Stress (Definition)

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...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

Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?

Spect images demonstrate inferior and apical reversibility from my nuclear stress test. Is a cardiac catherization must be done?

Not enough data...: Inferior ; apical reversibility means there is some ischemia in those regions. Without seeing the images it is difficult to tell how much. If there is very mild ischemia, some cardiologists may decide to do medical management (only medicines). If there is any significant amount of ischemia, cardiac catheterization is usually done. Again, it depends on the clinical scenario..Not enough data. ...Read more

Stressechoresults: abn stress ECG at 9.1mets, normal exercise stress echo with no evidence of stress induced myocardial ischemia. What does this mean?

Stressechoresults: abn stress ECG at 9.1mets, normal exercise stress echo with no evidence of stress induced myocardial ischemia. What does this mean?

Probably normal: The ECG is accurate about 70-80% of the time in diagnosing cad. Adding stress echo or nuclear imaging improves accuracy to above 90% when patient reaches his or her target rate. ...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

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

Myocardial perfusion imaging with Tc-99m Sestamibi after exercise
revealed no scintigraphic evidence of hemodynamically significant
ischemia. Medium-sized, mid to basal inferior wall
mild-to-moderate mostly fixed perfusion deficit, excep

Stress test: A stress test with myocardial perfusion imaging is a way of detecting whether the heart muscle is getting insufficient blood supply because of coronary artery disease. It can be normal even with lots of coronary plaque, because it only detects severe narrowings. If there is a "fixed" perfusion defect that generally suggests a scar in the heart muscle from prior heart attack. Need more info. ...Read more

INTERPRETATION

INFERIOR WALL HYPOKINESIS WITH STRESS?

Abnormal stress test: Stress induced wall motion abnormality is concerning for significant narrowing of the coronary artery which feeds the inferior wall of the heart. This is most commonly the right coronary artery. ...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

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

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Tests: Each of the tests listed has specific strengths and weaknesses. The choice of study depends on the specific information desired by the ordering physician and the capabilities of the performing laboratory. CT angio in many cases will produce the best images of the arteries of the three, MRA has its specific indications and stress echo doesn't show the vessels but shows the effects of serious ischem ...Read more

My cardiologist ordered a myocardial perfusion pet stress test with persantine, so what is it?

Stress test : This is a chemical stress test. You will be given a medication and then pet scan of your heart will be done to evaluate the blood flow in different parts of the heart. If there is any significant blockage, it will show up as a defect in the images. ...Read more

What is "dobutamine, stress echocardiography criteria"?

What is "dobutamine, stress echocardiography criteria"?

A screening test: Stress tests are largely done to identify patients at risk for heart attacks. For patients who cannot exercise due to arthritis or other reasons, Dobutamine is a drug that will mimic exercise, and allow a stress test to be done. It is not as good as exercise, but it is a reasonable alternative if exercise is not possible. ...Read more
