Does dietary sunflower seed oil improve coronary flow rate and left ventricular work compared to lard in isolated rat hearts?
Dietary sunflower seed oil increases coronary flow rate and left ventricular work in isolated rat hearts compared to lard, suggesting a positive effect on cardiac contractility.
Deckere et al. (1980) studied this question. Dietary sunflower seed oil vs. Lard was evaluated on Coronary flow rate and maximum left ventricular work. Dietary sunflower seed oil increased coronary flow rate and maximum left ventricular work by approximately 15% and 10%, respectively, compared to lard in isolated rat hearts.
