Dietary fatty acids alter left ventricular myocardial gene expression in Wistar rats.

ABSTRACT: Obesity increases the risk for cardiomyopathy in the absence of comorbidities. Myocardial structure is modified by dietary fatty acids. Left ventricular hypertrophy is associated with Western (WES) diet consumption, whereas intake of n-3 polyunsaturated fatty acids is associated with antihypertrophic effects. We previously observed no attenuation of left ventricular thickening after 3 months of docosahexaenoic acid (DHA) supplementation of a WES diet, compared with WES diet intake alone, in rats that had similar weight, adiposity, and insulin sensitivity to control animals. The objective of this study was to define left ventricular gene expression in these animals to determine whether diet alone was associated with a physiologic or pathologic hypertrophic response. We hypothesized that WES
