Researchers Find New Source of Dangerous Electrical Instability in the Heart

Sudden cardiac death resulting from fibrillation – erratic heartbeat due to electrical instability – is one of the leading causes of death in the United States. Now, researchers have discovered a fundamentally new source of that electrical instability, a development that could potentially lead to new methods for predicting and preventing life-threatening cardiac fibrillation.

Dietary Gluten Is Not Linked to Heart Risk in Non-Celiacs

A study revealed that while dietary gluten does not increase heart disease risk in people without celiac disease, limiting whole grains may increase their heart risk.

Less than half of individuals with peripheral artery disease, which is a narrowing of arteries to the limbs, stomach and head, are treated with appropriate medications and lifestyle counseling. These findings highlight the need to improve the quality of care for this high-risk group of individuals.

Scientists Find a Likely Genetic Driver of Smoking-Related Heart Disease

Cigarette smoking accounts for about one fifth of cases of coronary heart disease (CHD), one of the leading causes of death worldwide, but precisely how smoking leads to CHD has long been unclear. Now, a team has uncovered a molecule that may at least partly explain the smoking-CHD connection.

Mice with Missing Lipid-Modifying Enzyme Heal Better After Heart Attack

Using a mouse heart attack model, researchers have shown that knocking out one particular lipid-modifying enzyme, along with a short-term dietary excess of a certain lipid, can improve post-heart attack healing and clear inflammation.

Johns Hopkins researchers report that an analysis of survey responses and health records of more than 10,000 American adults for nearly 20 years suggests a “synergistic” link between exercise and good vitamin D levels in reducing the risk of heart attacks and stroke
