Hi I recently had a St Judes valve replacement November 2012, past operation in 1992 repair dissection of ascending aorta. 205 bariatric surgery, mediction to date inhibace, Eltroxine, Warfrin, Omeprozole, Metoprolol. At present I have swelling of my body, I recently was able to jog up to 1km with ease but now I find it hard to even walk a short distance without having to stop and catch my breath, can you advise if there is an alternative medication to the Metoprolol without such harsh side effects
