- This is based in what I understand from my doctor and reading up on
- the subject:
-
- Aural MVP symptoms (click or murmer) may come and go, and can vary due
- to position. But if the valve is actually prolapsed, echo will detect
- MVP at any time. (I don't know whether certain situations, such as
- temporarily elevated blood pressure, will make the prolapse more
- evident sometimes than others. I suspect so.).
-
- Chest pain in MVP does not behave like the typical stress-related
- chest pain one hears about associated with coronary artery disease.
- In coronary artery disease, the heart's blood supply is restricted,
- causing pain or other discomfort. In MVP, chest pain tends to come
- and go more slowly, and (I'm not certain about this part), is due to
- hyperkinetic activity of the heart - it has to work harder, since it
- pumps less efficiently. So basically, the muscle gets "tired".
-
- Caffiene stimulates the heart, and so avoiding it is likely to reduce
- the incidence of pain. Also, there is a complex of symptoms, often
- associated with MVP (but not necessarily causally related) that
- relates to how the body processes catcholamines (spelling is probably
- wrong). Now we're getting into an area I'm fuzzy on - corrections are
- requested. But I believe that adrenalin is a catcholamine. Anyway,
- the upshot is that getting yourself in a "stimulated" state is not
- going to help you. More empirically, cutting down on caffiene tends
- to make some MVP patients with bothersome symptoms feel better, at
- least with regard to their symptoms :-).
-
- It is my personal opinion that it is prudent to avoid things that
- cause chest pain. One potential long-term hazard of MVP is an
- enlarged heart, and associated problems, such as arhythmias. I don't
- know that chest pain is a sign that some "threshold" has been passed
- that may contribute to the development of this problem, but it seems
- clear that reducing the workload on the heart so that chest pain is
- not experienced is a step in the right direction. On the other hand,
- those who experience no symptoms probably have nothing to worry about.

- PS I am not a doctor.
-
- PPS I think that if you are having symptoms that you think may be
- caused by a hiatal hernia, then you should try taking antacids to see
- if that helps.
-
- PPPS Also watch out for muscular tension that can cause chest
- discomfort. Stress/anxiety can cause chest discomfort, and focusing on
- it can worsen it significantly. This has caused at least one person
- with MVP (me) become overly concerned about my condition in the past.
