In the beginning we did give carnitine to Pepper until I researched it
further and found that there are mixed results from studies, depending upon
the individual heart disease.
For instance: http://tinyurl.com/3hzdoe
"It was suggested that the l-carnitine-induced increase in left heart weight
might partially account for the postponed occurrence of pulmonary
hypertension in the early stage by elevating cardiac output, which might, in
turn, lead to the resulting increase in pulmonary pressure. In view of its
complex effects on cardiopulmonary haemodynamics,l-carnitine supplementation
may be impractical for reducing PHS"
Aside from the fact that you don't really know how much carnitine is in a
specific supplement because they aren't controlled, there seem to be other
questions such as EFA absorption:
"These findings suggest that the most likely mechanism for increased serum
carnitine is increased carnitine synthesis by the liver. The changes in
carnitine metabolism in SHR appear to occur between 5 and 10 wk of age,
because the carnitine levels in serum and organs were comparable in 5-wk-old
WKy and SHR. The observed alterations in tissue and serum carnitine levels
may result in altered fatty acid utilization in SHR."
There are some very interesting articles out there, and the big concern for
me was that if high blood pressure was a concern, carnitine seemed to have
an influence, whereas with HCM there wasn't a concern:
but then I am not a doctor, let alone a cardiac specialist, and the end
choice for us was to back off until we had better science available.
Does anyone have good scientific information on this?
Pat and all the boys.
