Hello @dwander501 and welcome to Mayo Clinic Connect. Your concern over the aortic aneurysm is certainly understandable and your search for the best opinion possible is important. You are wise to research and get other opinions.

You asked about "beta-blockers" which are one type of blood pressure medicine that also slows the heart rate. Here is some information on beta-blockers from Mayo Clinic's website, https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/beta-blockers/art-20044522. Perhaps you will see the name of your current BP med listed here.

From what you have posted, I understand that you have no symptoms at this time. Is that correct?

If you are comfortable sharing more, what BP med are you currently taking? Do you have a family history of aneurysms?

I've been taking 80 mg a day of Valsartin for years. This week I started 12.5 mg of Metoprolol Tartrate twice a day. I don't really notice any difference but I'm going to track my hear rate and BP next week.
