what is reverse redistribution abnormality?

is this a fancy word for blockage?

and  what is decreased function capacity?   And  is there treatment for this?

Well a reverse distribution abnormality is really not what is seems. It just means it's giving the opposite results to what you would expect.
For example, If you have a thallium test, they inject you with a radioactive isotope which binds to cells in the blood. These are then taken up by the heart muscle and glow, so the scanner can detect them. This means a cell is functioning properly, taking in substances from the blood. If you take a slice through the middle of the heart on the image, you would for example expect to see a nice bright complete circle. The hole in the middle is where the chambers are, the outside circle is the heart muscle. In a healthy heart, you would expect a full circle at rest, and a full circle under stress. If you have a blockage (partial) you would expect a full circle at rest, and a broken circle under stress. If you have had a heart attack, you would expect a broken circle at rest and stressed. Now an example of the reverse redistribution abnormality would be a broken circle at rest, and a full circle at stress. Most of these turn out to be normal but need confirmation with other tests.
What test did you have?

Thanks for looking at my post.

I have always a had sinus rhythm T-wave inversion.

My Stress test  was a standard Bruce Protocol and completed 2 minutes of stage lll,  of 8 minutes,  equivalent to 10 METS  placing me in Class l
  ( whatever that means)
I achieved a rate of 160 which is 94 % of my maximum rate.
test was terminated due to fatigue,

Occasional PVC'S were noted.

Resting images revealed moderate degree of perfusion defect in the basal lateral wall suggestive of reverse redistribution.   No  exercise induced left ventricular cavity dilation.

Baseline abnormal EKG-  ( Ive had that since I was teenager)
Decreased function capacity for my age
No myocardial  test shows no reversible ischmeic  changes
reverse redistribution abnormality in the basal inferior lateral wall.

I didn't speak with my Dr, I will on this Tuesday or Wednesday,  A Cath is scheduled for April 17,   One visit he did mention that he thought my heart wall might be getting thicker, I've  been on meds for HBP  since I was 20,  Im 53 now.

I'm sure I  have a stent placed,  I'm not sure about the rest..
Your thoughts ?

I think a cath is a wise decision by your cardiologist. I think they want to investigate the basal inferior lateral wall but they will of course see all the coronary arteries. It looks like the main interest is the top of the left ventricle, across to the rear/side. Please let us know if they find anything.
Thank you for this explanation! I know this post is 9 years old, but very helpful to me.  This is the condition reported on my nuclear stress test: small to moderate. mild reverse distribution defect, with an EKG ST/T abnormality.  Met with a cardiologist today. Referred for a echocardiogram and cardiac catheter procedure, but no explanation of what this condition is.   Thanks, very much!
