How much damage

[shazzdog]

Hi I had MI (NSTEMI) October and am on various drugs as the norm. What I'm trying to find out and nobody seems to be able to give me an answer to is how much heart muscle damage have I got. I had stent put in left artery due to narrowing and my latest ECG reads as follows.
SINUS BRADYCARDIA
T WAVE ABNORMALITY, POSSIBLE ANTERIOR ISCHEMIA  (-0.1+ MV T  WAVE IN V3/V4
Vent rate:   56 bpm
PR int:   197
QRS: dur: 96 ms
QT/QTc:   459/450 ms
P-R-T axes:   38  12  67
QTcB:       444 ms  
QTcF:    449ms
Thanks for any help

At best an EKG can give the possibility of heart muscle damage.  An echocardiogram (ultra sound) can evaluate heart's ventricle walls for any movement impairment by visual real time of the pumping heart.  Additionally, an echo software calculates the ejection fraction (EF), and that calculation indicates the amount of blood pumped out with each heartbeat. Heart muscle damage will be an EF below normal 55-75%, and heart failure is below 29%.
