One way of combating atherosclerosis is to reduce levels of “bad cholesterol” in the blood. Scientists at the Swedish medical university Karolinska Institutet have now identified the genes that bring about this beneficial effect.
A new study done with mice has discovered that supplements of lipoic acid can inhibit formation of arterial lesions, lower triglycerides, and reduce blood vessel inflammation and weight gain – all key issues for addressing cardiovascular disease.
Although the results cannot be directly extrapolated beyond the laboratory, researchers report that “they strongly suggest that lipoic acid supplementation may be useful as an inexpensive but effective intervention strategy . . . reducing known risk factors for the development of atherosclerosis and other inflammatory vascular diseases in humans.”
Overweight people who lose a moderate amount of weight get an immediate benefit in the form of better heart health, according to a study conducted at Washington University School of Medicine in St. Louis. And the heart improvements happen whether that weight is shed by eating less or exercising more.
University of Michigan scientists and their colleagues have helped characterize a previously unknown link in the chain of biochemical reactions implicated in some forms of heart disease.
The finding provides a new target for future drug therapies.
A diet rich in leafy vegetables may minimize the tissue damage caused by heart attacks, according to researchers at the Albert Einstein College of Medicine of Yeshiva University. Their findings, published in the November 12 Proceedings of the National Academy of Sciences, suggest that the chemical nitrite, found in many vegetables, could be the secret ingredient in the heart-healthy Mediterranean diet.
An extensive swedish study from the Sahlgrenska Academy has established that surgery reduces premature death in patients with severe obesity. A long-term follow up has shown that mortality is significantly lower among patients who undergo surgery than among those who do not.
