Link between a mitochondrial defect and heart disease

A defect in mitochondria in the heart causes dilated cardiomyopathy, leading to heart disease and early death, according to a new study. The research shows that a diet rich in fatty acids can prevent heart disease and increase survival of the mice with this condition. Given the links between a high-fat diet and the risk of atherosclerosis, more research is needed to show if the result could translate into a benefit for a specific patient group.
