Why does an elevated pulse from anger/anxiety contribute towards heart problems, but during exercise a fast pulse is healthy?

Question

I recently had a terrible disagreement with someone and everytime I think about it I start shaking and my heart starts pounding from adrenaline, which according to Google is unhealthy. But our hearts are accelerated when exercising, which is supposed to be a good thing – so what is the difference?
