To examine how dietary fish oil influences heart membrane phospholipid fatty acid composition and protects against myocardial ischemic injury in rats.
Fed rats for four weeks on diets containing 5% (12 energy percent) menhaden oil or 5% (12 energy percent) corn oil.
Induced myocardial ischemia via coronary artery ligation and quantified damage by measuring the loss of myocardial creatine kinase.
Evaluated total cardiac phospholipids, cholesterol, double-bond index, and the fatty acyl profile across specific phospholipid classes.
Menhaden oil significantly reduced the loss of myocardial creatine kinase following coronary artery ligation compared with corn oil, without altering total myocardial phospholipid or cholesterol levels.
Menhaden oil significantly elevated total phospholipid saturation, double-bond index, and the n-3/n-6 ratio, with selective incorporation of individual n-3 fatty acids (20:5, 22:5, and 22:6) across phospholipid classes.
Dietary menhaden oil increased saturation in phosphatidylcholine without altering its double-bond index, while simultaneously increasing both saturation and double-bond index in phosphatidylethanolamine.
