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

Nuclear stress test results came back normal. However, i'm still feeling symptoms. Am I just being dumb? Should I just be content w/the results?

Nuclear stress test results came back normal. However, i'm still feeling symptoms. Am I just being dumb? Should I just be content w/the results?

Not Dumb.: If the stress test test is negative, you still need to find why you are having symptoms. All you have done is found a reason you are not having them. ...Read more

back in may i had a nuclear stress test results could not determine if the image was a breast artifact or something else and a PET scan was warranted .. in other testing he had done the same day ischemia was found .. when went for follow-up he said i did

 back in may i had a nuclear stress test results could not determine if the image was a breast artifact or something else and a PET scan was warranted .. in other testing he had done the same day ischemia was found .. when went for follow-up he said i did

SPECT vs. PET: On regular myocardial perfusion SPECT imaging, large breasts and large body habitus can cause attenuation artifacts. This is often avoided on cardiac PET where attenuation correction is used. If the breast shifts between stress and rest SPECT imaging, false positive for ischemia could occur. ...Read more

I had a normal echocardiogram but a abnormal nuclear stress test. I was told that a abnormal test means you have more than 70% blockages?

  I had a normal echocardiogram but a abnormal nuclear stress test. I was told that a abnormal  test means you have  more than 70% blockages?

Physiologically,: arterial blockages are usually not symptomatic or highly obvious on noninvasive testing until they reach 70%. The abnormal test is wrong (falsely positive) 15% of the time too so you won't know for certain without an invasive test or perhaps very high quality CT angiogram. Discuss these concerns with your health care provider to figure out what your next step should be in your evaluation. ...Read more

Recently had a nuclear stress test and results stated possible small focus of ischemia of the mid anterior wall. Ejection fraction 59%?

Recently had a nuclear stress test and results stated possible small focus of ischemia of the mid anterior wall. Ejection fraction 59%?

Ejection fraction nl: An ejection fraction the 59% means that the pumping function of your heart is normal. A "possible small focus of ischemia of the mid-anterior wall" can mean that when you're exercising not enough blood flow gets through to a small area of your heart. Usually a test result like that will lead to a cardiac catheterization to see if there is a significant blockage of an artery to the heart muscle. ...Read more

Does poor r wave progressive and nonspecific st&t adnormal waves mean you had a heart attack. The findings were from a nuclear stress test.

Does poor r  wave progressive and nonspecific st&t adnormal waves mean you had a heart attack.  The findings were from a nuclear stress test.

Poor R wave: Poor R wave progression could be seen in old anterior myocardial infarction (old heart attack), in lead misplacement of precordial leads by inexperienced ekg technician, also can be seen pulmonary diseases, WPW syndrome, and dextrocardia. Dextrocardia is very rare. Wpw will be seen in much young age. If you have old heart attack you should see it in nuclear stress test. ...Read more

How reassured (typically that is) should one feel about the possibility of a heart attack after receiving a negative nuclear stress test result?

How reassured (typically that is) should one feel about the possibility of a heart attack after receiving a negative nuclear stress test result?

Not perfect: It is reassuring but not perfect. The nuclear study relies on differential distribution of blood flow and the dye. Most CAD show distribution in vessels unequally, therefore, the dye will be distributed unequally. If there is diffuse disease, the distribution could be equal and will miss the differential and will read as no disease. Talk to your md or cardiologist if in doubt of symptoms. ...Read more

Ct scan results dr said pictures weren't very good. Wants me to get an nuclear stress test. Would it be feasible to ask for another CT scan?

Ct scan results dr said pictures weren't very good. 
Wants me to get an nuclear stress test. Would it be feasible to ask for another CT scan?

Unadvised but possib: Getting another CT scan is 99% likely to give the same picture as the 1st, barring an obvious problem (like the machine broke down, which they would have informed you at the site). Not sure what the nuclear stress test (cardiac?) or the CT scan (brain?) was for, but at this point, another modality is more likely to provide information than repeating the same test. CT scans involve lots of radiatio ...Read more

Another modality is more likely to provide information than repeating the same test. CT scans involve lots of radiation, & show calcium deposits & perhaps blood flow, but not if heart is affected.

What is a nuclear stress test?

What is a nuclear stress test?

Nuclear stress test: The patient walks on a treadmill or other exercise device or has a medication injected to simulate exercise, when the exercise or medicine is in progress a radioactive agent is injected which goes into the heart and can be imaged to show the blood flow into the heart muscle. The information shows if enough blood gets into the heart muscle and other information. ...Read more

Can a nuclear stress test cause you problems?

Can a nuclear stress test cause you problems?

Typically not: The only "risk" would be during the stress part, when one runs on a treadmill or gets a drug alternative. However, there is little risk here because this is monitored with an ekg and supervised by a cardiologist/nuclear physician. One drug that is used for stress even has an agent that can reverse its side effects. In summary, under normal standard-of care-conditions, there should be little risk. ...Read more

My cardiology order a nuclear stress test can you explain what is this thanks?

Stress test: A nuclear stress test detects blood supply to the heart. A radioactive tracer is injected into the veins at peak exercise or with a vasodilator. The tracer is taken up by the heart cells and the uprake is proportional to blood flow. By comparing uptake at rest versus exercise we can determine if blood flow is compromised. ...Read more

What is the average cost of a cardiac nuclear stress test?

Varies: It varies depending on type of stress e.g. Treadmill or which pharmaceutical. It also varies by location if you do it in a doctor's office or clinic or hospital. Practices charge a wide range too. A wide range from 400s to 900s or higher for cash patients. What insurances pay and copays may be a lot different.

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

You : You will be sufficiently radioactive to set off alarms at airports, ferry terminals, and border crossings. The sensitivity of these devices is high on purpose. However, the amount of radiation a patient emits after a cardiac nuclear scan is not considered dangerous to others. Notice that the technologists who perform these tests do not wear lead or other radiation protection and they are around "radioactive" patients every day. For the sake of completeness, however, i will add that pregnant women should not undergo this test and anyone who thinks they might be pregnant should have a pregnancy test before having any kind of radionuclide scan. ...Read more

What can you tell me about the cardiolite nuclear stress test?

Myocardial scan: A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi (cardiolite) are injected intravenously and travel through blood to heart muscle.2 sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease ...Read more

If i'm too weak to do the exercise nuclear stress test next week will they do the injection kind? I'm worried I won't be able to. Havent been eating.

Discuss with Cardio: If you are feeling more weak than prior to having the stress test scheduled, I would recommend you have a doctor examine you right away. It could be a sign of worsening health (possibly your heart). If this has been an ongoing concern, however, please consider discussing your limitations with the Cardiologist. They can inject you with "dipyridamole" which puts similar stress on your heart. ...Read more
