I had an appointment with my cardiologist last Wednesday. I told her I am swimming OK (not far off pre surgery levels) but when I run I am a lot slower and still struggle running on hills. This has not improved over the past few months and it feels like it will not improve much more. I went for a training run with some other runners from my club last week. These were steady runners but I could not keep up. The pace was steady but I was breathing very hard and it felt like the muscles were tightening up. I eventually turned back and jogged back to the start. I felt OK going at my pace and it also felt I could run with them if I met them later on (when I had warmed up). The cardiologist virtually said she (or her colleagues) do not have much experience with someone who was fit before surgery. She said most people see an improvement after surgery but they were not very fit before hand. Have any of you active "valvers" got cardiologist with experience with fitter patients and if so are they helpful with their advice on training.
