Before my surgery in February, I would get winded when I climbed stairs. I realized after I got further along in my knowledge of my mitral valve issue, I had had this symptom for years, or at least that's what I attributed it to. Therefore, knowing I had the problem, I avoided exercise with any type of stair climbing. Now that I've had my mitral valve repair, I expected to be able to climb stairs with no problems but I still notice my heart rate picks up and other related symptoms. I am able to ride a bike for 25 miles, walk 5 miles, jog 3 miles, but I am afraid of stairs. Should I try building up with various stair exercises or should I be concerned and avoid stairs until my appointment in December with my cardio?
