Hi .On my report of stress echo results it says Ischemia in 5 segments LAD territory .Does anyone know what 5 segments means .One reply from a doctor was "its confusing" and didn't bother to even try to explain it !

Hi Collectone

Sorry to hear that you had an unhelpful response from a doctor, I can imagine that was frustrating for you.

I think it means 5 areas within the LAD region but there may be someone better informed who can confirm for definite.

I hope that you get the answers and clarity that you’re seeking.

Best wishes

To allow for accurate echo interpretation of the left ventricle wall it is divided into 17 segments. The heart wall motion can be restricted in areas of reduced blood flow ( ischemia) and not pump as smoothly or efficiently. The cardiologist hopefully will discuss your findings and decide further investigation is required.

Hi Collectone, not sure if this helps, but I was told my damaged/dead heart tissue (infarction) was spread throughout the RCA territory, ie, throughout the area the RCA artery supplies, passed the blockage I had, which triggered my heart attack. It also said this was still viable, still haven't quite worked out exactly what that means! Anyway, the LAD supplies a large area of the heart, so it does sound as if this could be well spread in different parts of the territory. As you know ischaemia just means narrowing, and surprisingly the arteries can sometimes get quite narrowed before the person can detect any effect, the human heart can be really quite wonderful sometimes. Good luck

Hi. The left ventricle of the heart is divided into 17 segments (not physically, just conceptually) to over simplify - imagine the ventricle is a cone. There are 3 levels from top to bottom, with 6, 6 and 4 sections in each respectively, giving 16 conceptual muscle segments (17 is the tip which does not contract). About 7 of these segments, a bit over a third of them, are fed by the LAD - left anterior descending artery - one of the main coronary arteries. My understanding of your results is that 5 of your segments were not getting enough oxygen during the test and they were among those fed by the LAD. This might suggest an obstruction to the LAD. I am just a lay person, not a doctor though.

Here is a link that explains it with much more clarity and authority than I do. ecgwaves.com/topic/left-ven....

Hi Collectone

I am waiting for a stress echo test, I had a HA in September and they think I have angina, although it's not been confirmed and I have daily chest pains, relieved by gtn. Do you have a cardiac nurse that could explain this to you ? Or are you waiting for a clinic appointment? I hope you get the answer as soon as possible.
