EKG and Angiogram after MI

Can anyone nderstand this, I am trying to work out wich part of my heart muscle was damaged as a result of inadequate blood spply following my MI

My 2D stress imaging EKG has a report which says the following.

Post stress echocardiogram.
Immediately post stress, the hypokinetic inferior and posterior walls augmented to a medium degree.
No clinical ischemia on the treadmill
There are regional wall motion abnormalities at rest. Specifically , the inferior and posterior mycardial segments, which are severely hypo-kinetic.
It then says abnormal baseline echo with failure of appropriate augmentation of the akinetic inferior and posterior walls.
Arrhythmias during exercise;rare PVC'S during recovery;rare PVC'S.

I have a cardiac catheterization report which says

PROCEDURES PERFORMED; LHC,COR, and LV.
ATERIAL ACCESS SITE; right femoral artery 5F


RCA; large caliber with 40/45% mid stenosis.
LAD; PROXIMAL LAD mildly aneurysmal 40% mid LAD just beyond bifurcation with large diseased diagonal branch.

CIRC; 25% CIRCMFLEX DISEASE

LV; abnormal left ventricular systolic function with diaphragmatic and anterolateral wall motion abnormalties and estimated ejection fraction 25% No significant MR

I don't follow this and the DVD jst shows scenes that all seem ok apart from 12 13.
There is one more comment that says ATHEROSCLER UNSPEC VESSELS (2) of
