May affect membrane function in hypertrophied myocardium; hypothesis-generating and requires human validation before clinical consideration.
Pressure-overload cardiac hypertrophy is associated with specific alterations in myocardial phospholipid metabolism and fatty acyl composition, which may affect membrane function.
Reibel et al. (1986) studied Pressure-overload cardiac hypertrophy. Abdominal aortic constriction was evaluated on Content and fatty acyl composition of phospholipids. Pressure-overload cardiac hypertrophy induced by abdominal aortic constriction significantly elevated myocardial phosphatidylcholine, sphingomyelin, and phosphatidylinositol by 10%, 10%, and 20%.
