Almost forty year cardiac nurse.
It’s really up to each person whether they want to go on medication or try lifestyle changes first.
The important part is that it gets down and stays down, one way or another.
Why?
Because when your heart is working extra hard with each beat, over time, there can be changes in the heart tissue itself from the added stress, and the heart can wind up becoming stiff and not filling correctly, which means it can’t pump out enough blood with each beat, and that’s a form of
heart failure. People often look back when this happens and wish they’d taken it more seriously.
Is the OP’s BP at a level which requires medication? That is information that only the prescribing clinician knows. My guess is that there are additional medical factors that we don’t know about that put the person at risk and they are trying to be proactive about it.
Risk factor reduction is really huge in cardiac care. Many of us don’t take it seriously, though, until something happens.
