I'm just a patient like yourself and can't give medical advice. If it were me, I would want more information on treatments available for my condition and/or what kind of lifestyle changes can I make to help the condition and reduce the risks involved. It really is helpful to be your own advocate when it comes to your health. You might find the following site helpful for working with your doctor or care team:

Hi, do what ever your doctors tell you to do but also consider the following.

Get a BP cuff and track it at home at the same time every day, after resting for 5 minutes with feet flat on floor (look up other things). The blood pressure cuff you get at home can have blue tooth and sync to your phone for reports and tracking.

Reduce sodium

If you want to get super serious about lifestyle look up Dr. Dean Ornish and people like him.

With your doctors, Manage it if it gets that high often (med's or lifestyle or both) , don't ignore it or it may lead to a more serious issue/event you don't need that is preventable, when you are older, or if it gets higher.

If you get a good internal medicine doctor they may be able to guide you and serve as your primary doctor possibly if helpful. Or a Cardiologist if you want more answers or to review your test results/reasons/actions related to what you noted "vascular sclerosis".

Don't stress but take action, you have the information and age on your side. You may find it goes back down if you do a few minor things.
