@pattynelson It sounds like you are addressing your concerns thoughtfully to set yourself up for a successful surgery and recovery. Thank you for providing a bit more about your situation so others will know more how to comment.

I want to help you find diabetics to talk to that have been through open heart surgery so you can prepare for managing your diabetes throughout the process. I am tagging others that have commented on discussions related to members with diabetes looking at open heart surgeries hoping they will have first-hand experience (or know someone who does): @acarrollga1956 , @kbauer23 , @bjanderson , @lioness. @badmac created a discussion you may want to browse, Freaking out a bit - upcoming surgery https://connect.mayoclinic.org/discussion/freaking-out-a-bit/

@laura1970 has provided excellent guidance for you to know before meeting with your surgeon again. You mention having a heart cath. When is it scheduled?
