Pain in mitral valve prolapse

Thirty subjects with mitral valve prolapse were carefully observed, in order to investigate whether chest pain, characteristic of angina pectoris, was present. No cases of angina pectoris or of heart pain were observed. A characteristic which did emerge was that 86% of the subjects suffered a typical myofascial pain of the muscles of the chest. There does not appear to be a clear relationship between mitral valve prolapse and myofascial pain.
