Hey there. I had a complete aortic dissection in 2015 which was sudden and an emergency. My best recommendations for you are that you’re not doing any exercises that involves holding your breath. No planking, no dead lifting, nothing that involves valsalva maneuver— forcefully exhaling against a closed airway to increase pressure in the chest and abdomen. I would absolutely take it easy. Walking is fine. Weightlifting is out. Do not take advice from anyone who has not survived a sudden aortic dissection or isn’t a cardiothoracic surgeon with an expertise and repairing dissected aortas. Keep your blood pressure down and your spirits up. I would have traded my left arm to know that I had a problem in order to deal with it. You do not want to dissect. Take this seriously. it was a really treacherous and difficult road back from this surgery for me and I would simply encourage you to have a schedule operation in a major heart care center near you. If this is planned and scheduled, it is imminently successful. If you dissect suddenly and you’re not across the street from cardiac ICU and surgical center, you’re gonna have a hard time surviving it. That’s the reality. The great news for you is you know you have a problem and you are not yet a surgical candidate at this point. Keep your blood pressure down. Feel free to post here right back directly to me if you want to talk more. Peace.
