Interpreting results of nuclear stress test
Posted in the Cardiology Forum
#1 Jan 8, 2011
My friendly cardiologist had me to get a nuclear stress test and then mailed me the written report, somehow expecting me to figure out what it means.
What is right ventricle grossly normal? Is that a concern?
What is resting ECG revealed non specific ST-T wave changes? Is that a concern?
Wat is rare PVC's noted during recovery? Is that a concern?
Any insight would be greatly appreciated.

1. RV grossly normal is not a concern. RV is not the chamber of concern during nuclear stress tests. In certain types of stress testing, the uptake of nuclear tracer in the RV may be of concern.
2. Nonspecific ST-T change on resting ECG.- may or may not be important depending on the symptoms prompting a stress test.
3. Rare PVCs in recovery. Not a concern.
Important and concerning parts of the report would include areas of "reversible defect", "ischemia", "transient ischemic dilation", "ST segment depression on ECG during the test"... although if you had these, your cardiologist would most likely had you come in for cardiac angiography or at least further discussion.
Hope is helpful.

I hope no one minds me asking this question here..
I am male/50 and had a stress test last week.
The result was a inferior wall ischimia or indication of a lack of blood flow to the inferior wall.
When imaging the heart during a stress test, how close does the imaging device need to be to your chest?
I have read that the distance between the imaging device and my heart can give this specific type of false positive...
I have had stress tests in the past where the imaging device nearly touched my chest as it moved from side to side.
In this test I noted that the device was actually about 6 to 8 inches above my chest and I recall thinking that it was unusual but did not think much more about it...
So my question is,, could that result in a false positive ... the transitions were smooth and actually just appeared slightly faded.. my dr. didn't think it was urgent but wants a catheterization done ..
Now I have a dilemma... if this is a false positive then I am going to be wasting alot of money on an unnecessary catheterization procedure because the technician mucked up the test.. imo
and if its NOT a false positive I'm concerned about the long term implications which I will just have to deal with... I plan to have it done unless there is another way to prove/disprove the indications...
no chest pains, no history of heart problems, non smoker, non drinker... 6ft 5, 250 lbs... my average weight has always been around 240.. am dieting and exercising again ...

I had a stress test done and need help interpreting it. I am a 44/female.
-Subdiaphragmatic attenuation is noted (though motion was noted on rest n stress images correction was not employed).
-Mild intensity small sized defect, located in the distal anterior and apical wall with no change from rest to stress images. This defect suggests infarction vs. artifact in the wall.
-Gated SPECT imaging demonstrates abnormal septal motion of the distal anterior and apical wall.
-Left ventricular ejection fraction was calculated to be 56%.
Nuclear Perfusion Impression:
1. Probably normal myocardial perfusion sestamibi SPECT imaging after the L.S. testing. There is a small area of infarction vs. artifact in the distal anterior and apical wall. No evidence of significant ischemia.
2. Overall left ventricular function was normal with abnormal septal motion regional wall motion abnormalities as noted.

I have an implanted pacemaker, therefore to renew my OUVP 6 PAK license the USCG required me to have a nuclear stress test. Their requirements included:
GXT should be Bruce Protocol to at least 8 METS. Unfortunately I was taken to 7 METS.(someone forgot to read the guidelines) The results were all positive. My question is...What does METS mean and what is the difference in a 7 or an 8?

I had a Nuclear Myocardial Perfusion test...here are the findings...I would appreciate if someone can tell me what all this means in a way that I understand it....?
Myocardial perfusion imaging reveals a small to moderate sized area of severely decreased activity in the distal inferior apical wall which remains fixed, consistent with prior infract. There is no ischemia is present. The remaining walls demonstrate normal perfusion. LV cavity size appears normal in both imaging sets. Gated myocardial imaging reveals moderately reduced LV systolic function with a calculated ejection fraction of 38%.
What does all this mean?

So, basically, a cardio stress test is pretty much useless.

I had a nuclear stress test. The result is:
1) Probable normal myocardial perfusion study with a small mild mid-inferior wall reversible defect that likely represents soft tissue attenuation, but ischemia cannot be completely excluded due to its reversibility. Normal wall motion and EF;
What odes this mean? I will appreciate a feedback.

Mine did the same, so I have a question. Does anyone know what this means- A mild and fixed perfusion defect involving the anterior wall in mid ventricle was noted most likely due to soft tissue breast attenuation artifact. No previous study for comparison.

i had a stress test that revealed a medium sized perfusion in the inferior wall what does this mean

Can I get an interpretation of these stress results? Probably abnormal LV perfusion and probably abnormal regadenoson mayocardial perfusion with Tc-99m sestamibi imaging. A small completely reversible apical to mid anterior defect with normal wall motion, defect consistent with ishemia .

My husbands diagnosis: CHF, CAD, LBBB, PVC's, and Chronic ischemic heart disease. My husband had a cardiac cath and stent placed in his RCA 2 ears ago after an echo showed LVEF of 25%. My husband recently had an echo and SPECT he was given cardiolite and lexiscan. The echo showed his LVEF to be 45% at this time. I have questions regarding results which are as follows and the significance of each: What is mild concentric left ventricular hypertrophy? What is abnormal contraction sequence due to intraventricular conduction defect? What does the left ventricular apex is severely hypokinetic mean? What is trace mitral regurgitation? What does significant precordial fat pad is present mean? Whast does there is a medium sizd partially reversible defect in the LV inferoseptal wall mean? What does positive nuclear stress imaging suggestive of inducible ischemia in the LV septal wall mean? What does nuclear stress image findings indicative of intermediate risk for future ischemic event mean? What does LV chamber size is mildly enlarged mean? SPECT perfusion findings medium sized partially reversible defect in the interoseptal wall that is consistent with peri-infarct ischemia. Ischemic burden is quantitated at:SSS: 13, SRS:8, SDS:4 ,LHR:0.43.
