@carsok Wait and see, that's about where we all are at. As long as the Dr. are watching it and you continue to get the CT scans when they say that is about all you can do. Be nice to our body/heart. Eat healthy, get exercise etc... I am trying to follow through with these things, but I am lacking. It's good that your's had stayed at 4.3cm for so long. You must be doing something right. Keep it up.
