Do you have a cardiologist you see? That question would be best for them. I do not think getting sugar under control can do much to reverse what has been done but improving health by reducing blood sugars will improve healing capabilities as well as making any medical intervention more possible as there are procedures they may not do when blood sugars are high
Its Friday, let's celebrate. Share your biggest win for the week. It may just be that you got up and showered, it may be you had a great blood sugar reading. Let's all celebrate one another. As always, I'll go first. I put myself first and got all my workouts in this week. Self care isn't selfish!
