Prostaglandins and polyunsaturated fatty acids in heart muscle
Abstract:
1. Dietary lipids modify fatty acid composition of cardiac lipids. Polyunsaturated fatty acids replace less unsaturated fatty acids in phospholipds. 2. Mortality following isoproterenol-stimulation increase with decreasing amount of arachidonic acid in cardiac phospholipds. 3. In normal human heart muscle the ratio of essential, omega-6/nonessential, omega-3 fatty acids diminshes from age 17 to age 50 years. 4. In sudden cardiac death the ratio of prostaglandin substrate, C20:4, to prostaglandin inhibitor, C22:6, is frequently much higher than expected.
