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?

Answer 1

A high heart rate is a symptom, not a condition, and as such is neither good nor bad.

The underlying factors link to stress and anxiety that also can elevate heart rate are bad for you.

Similarly, cardiovascular exercise that also elevates your heart rate is good for you.
