Dear Laurette, thank you for your question. Mitral valve prolapse (MVP)
can be a worrisome disorder for many people because of the symptoms
associated with it (shortness of breath, palpitations, and chest pains).
Fortunately, these symptoms almost always do not signify serious cardiac
disease and are caused by processes that we don't know too much about.
For a more detailed description of MVP, you should look at the April 2nd
questions in this forum and read the one about MVP. In your case, however,
I agree with your cardiologist that you may have asthma. Shortness of
breath with asthma is caused by bronchial muscle constriction which
reduces the diameter of the airways to make it harder for someone to breath.
Asthma can be precipitated by allergies to dusts, pollens, etc.; cold
weather; stress; and exercise. Pulmonary function tests measure the
ability of the lungs and airways to move air and exchange air in and out.
Since your PFT's were abnormal, your symptoms sound classic for asthma,
and your symptoms were worsened with exercise, my strongest suspicion is
that you have asthma. Asthma can be treated with inhaled medications that
dilate the airways and reduce the inflammation in the lining of the airways.
Thus, I would consult with your internist or a pulmonologist for further
treatment and testing. If further testing reveals no asthma, then your
symptoms could be attributed to the MVP but as I previously mentioned, there
wouldn't be much treatment in that case because shortness of breath in MVP
does not appear to be caused by abnormal lungs. I hope you find this information
