The description is not clear or detailed enough to conclude....
They must have done an ECHO - if you could get it, the report will clearly show!
Probably it is ANEURYSM
- a portion of the heart muscle loses viability after a heart attack
/ it is replaced by thin fibrous scar tissue, which can not function like a muscle.
The location and extent of involvement, the efficiency of working (say - ejection fraction
), other events like arrhythmia
(irregular beats), age, co-existing diseases - are some of the many factors that will decide on further course of action. There is no specific 'medicine'.
