When heart enzymes are elevated is that permanent damage to the heart muscle?

If I injure a muscle in my arm, over time I feel confident it will heal, and can be just like new. I’m not clear if the heart muscle works the same way? I understand with a heart attack there can be permanent damage, but let’s say heart enzymes are only slightly elevated and then go back to normal in the next 24 hours, was there permanent damage, maybe ever so slight, or does the heart heal if the trauma was very small?

I have googled to try to find the answer, and all I find is explanations of heart attacks, heart trauma, and why the enzymes go up.
