I have tricuspid and mitral regurgitation. I need to exercise to keep the flab awaybut due to my busy schedule and lazy nature I opt to limb stairs as exercise.Someonbe told me that this is going to create extra load on my heart and is not recommended. but I think it should be okay..so anyone can tell me what to do?

If your doctor recommends that you exercise and get some cardio exercise than climbing stairs is a good exercise. Just be aware of your body. If you start to get really tired, or feel dehydrated, get off the next floor and take the elevator. Getting your heart pumping should be good for you.. your body needs it, but I would talk to your doctor about it if you're concerned.

If its physically too straining on you, it is not recomended to climb that. You should consult your physician.

If you start a regular exercise program (with your doctor's advice), don't try and tackle 12 flights at first. Try 2 for a couple weeks, then 4, then 8, then 12...and always monitor your pulse. Make sure you're not overexerting your energy. If you feel any irregular symptoms, immediately pull back on the number of stairs you're trying. Again, all the specs about risks and what-not can be answered by your doc.
