Damaged heart muscle

Are fatigue and exercise intolerance  permanent symptoms of a damaged heart muscle cause by a heart attack?
What are some other symptoms?

thanks in advance

No, they can be symptoms of heart failure that might or may be not, be caused by a heart attack.
But also can be symptoms  of other problems like tiroide issues so the only logical advise is  to go to the doctor.
