Summary
Hydration did not change mitral valve prolapse (MVP) diagnosis. However, oral hydration subtly altered auscultation findings in MVP patients, suggesting hydration impacts how MVP sounds.
Area of Science:
- Cardiology
- Physiology
Background:
- Mitral valve prolapse (MVP) is a common valvular heart condition.
- Auscultatory findings in MVP can be variable.
- The impact of hydration status on MVP expression is not well understood.
Purpose of the Study:
- To investigate the effect of oral hydration on mitral valve prolapse (MVP).
- To assess changes in auscultation and echocardiographic findings after hydration.
Main Methods:
- Ten subjects with diagnosed MVP underwent oral hydration (1 L fluid).
- Cardiac examinations (auscultation and echocardiography) were performed before and after hydration.
- Changes in weight, cardiac output, and specific MVP indicators were analyzed.
Main Results:
- Hydration increased subject weight and cardiac output.
- All subjects maintained their MVP diagnosis post-hydration.
- Six of nine subjects showed altered auscultatory findings, with loss of clicks or murmurs.
- Echocardiographic evidence of MVP persisted in all subjects, with minor changes in three.
Conclusions:
- Oral hydration does not alter the diagnosis of mitral valve prolapse (MVP).
- Hydration can significantly affect the auscultatory characteristics of MVP.
- These findings may help explain the variability in auscultatory findings observed in MVP patients.
