No immediate clinical implications for HF diets; hypothesis-generating for saturated fat effects in rodent post-infarct models.

High saturated fat feeding improves myocardial function at rest and during physiological stress in infarcted rat hearts, suggesting potential cardioprotective mechanisms in mild to moderate HF/LV dysfunction.
Berthiaume et al. (2010) studied Heart failure (post-myocardial infarction). High saturated fat diet vs. Normal chow (10% kcal fat) was evaluated on LV +dP/dtmax (mmHg/s × 10³) at baseline (p=<0.05). A high saturated fat diet improved myocardial contractile function at rest and during physiological stress in rats with infarction-induced heart failure compared to normal chow.
