Sorry I accidentally pushed the send button before I was finished with my comment! What I was trying to say is that the wall of the left atrium is moderately thick. That has made the left atrium smaller. Also the wall is stiffer and not contracting properly. It is a frightening diagnosis to read that you have heart failure even if it is only stage one. I have done a lot of reading about diastolic heart failure and there are confusing treatment available. I’m just wondering if anyone else on the forum has had this experience and can shed some light on it for me.
