A good article.
Another thing to watch -- I knew I had aortic stenosis, so I was carefully watching for the onset of symptoms for almost 9 years. None (other than fatigue) appeared, but my cardio and I decided it was time to replace the valve. When I had the obligatory heart catheterization in preparation for surgery, I was truly stunned to learn that I have an artery that is blocked seriously enough to require bypass along with the valve replacement. I was experiencing what turned out to be some early symptoms of trouble from the blockage, but I shrugged it off and blamed it on the valve slowly progressing. I believe that if I hadn't been preparing for the valve surgery, I probably would have gone on in denial and had a major heart attack. Moral of the story. . . NONE of these symptoms are trivial. Discuss with your cardio, and if you can't comfortably talk with the cardio, you've got the wrong one!
