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

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

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

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

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

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. The Nuc stress will. ...Read more

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

Stress Test (Definition)

A stress test is a cardiac test which can include walking on a treadmill and monitoring your heart while you are walking. They can also inject you with a nuclear material and do a more comprehensive scan on your heart to check for blockage. They can also do a chemical stress test which omits the need to ...Read more
