hi ,I had a mechanical aortic valve replacement and a anrysyum repair a few years ago .
I've been on 5 mg bisoprolol since surgery. I seemed to have asthma after surgery certainly didn't have it before. There were doctors arguing as to whether I had it or not at hospital after my op anyway several years down the line and on inhalers I definitely have asthma and have just been told to stop taking the bisoprolol as its not suitable for asthmaticasthmatics. Anyone else had asthma after open heart surgery?.
