Oleate, a common dietary fat found in olive oil, restored proper metabolism of fuel in an animal model of heart failure, researchers report. Heart failure affects nearly 5 million Americans, and more than half a million new cases are diagnosed each year. Heart failure is not the same as having a heart attack — it is a chronic disease state where the heart becomes enlarged, or hypertrophic, in response to chronic high blood pressure which requires it to work harder to pump blood.
The findings are reported in the journal Circulation by researchers at University of Illinois at Chicago College of Medicine.
Heart failure affects nearly 5 million Americans, and more than half a million new cases are diagnosed each year. Heart failure is not the same as having a heart attack — it is a chronic disease state where the heart becomes enlarged, or hypertrophic, in response to chronic high blood pressure which requires it to work harder to pump blood. As the heart walls grow thick, the volume of blood pumped out diminishes and can no longer supply the body with enough nutrients.
Failing hearts are also unable to properly process or store the fats they use for fuel, which are contained within tiny droplets called lipid bodies in heart muscle cells. The inability to use fats, the heart's primary fuel source, causes the muscle to become starved for energy. Fats failing hearts …
Previous studies have suggested that sticking to a diet high in olive oil can be as effective as statins at reducing the risk of a heart attack. Researchers in Barcelona found that volunteers assigned to a Mediterranean-type diet had a 30 per cent lower risk of having a heart attack or stroke over five years, compared with those randomly selected for the low fat diet. A review of 50 academic studies in 2011 found that diets high in olive oil lowered the risk of developing conditions such as diabetes, obesity and high blood pressure.
