New research can improve heart health (7/2/2014)

For the first time, researchers at the University of Copenhagen and Rigshospitalet are able to show that a particular gene variant lowers the risk of arteriosclerosis by 41 percent, making the variant an obvious target for future drugs for cardiovascular disease treatment. The results are based on data from nearly 76,000 subjects and have just been published in the renowned New England Journal of Medicine. ...> Full Article


Broken gene found to protect against heart disease (7/2/2014)

By scouring the DNA of thousands of patients, researchers at the Broad Institute, Massachusetts General Hospital, and their colleagues have discovered four rare gene mutations that not only lower the levels of triglycerides, a type of fat in the blood, but also significantly reduce a person's risk of coronary heart disease -- dropping it by 40 percent. The mutations all cripple the same gene, APOC3, suggesting a powerful strategy in developing new drugs against heart disease. ...> Full Article



Bacteria help explain why stress, fear trigger heart attacks (6/22/2014)

Bacteria help explain why stress, fear trigger heart attacksScientists believe they have an explanation for the axiom that stress, emotional shock, or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream, according to research published in published today in mBio, the online open-access journal of the American Society for Microbiology. ...> Full Article

Researcher finds a new role for the benefits of oxygen (10/15/2013)

During a heart attack when the flow of oxygen-rich blood to a section of the heart is interrupted, and not quickly restored, heart muscle begins dying. Deprived of oxygen and other essential nutrients, cell death continues possibly leading to progressive loss of heart function and congestive heart failure. Dartmouth researchers found that dying heart cells still contain enough oxygen for metabolism, and additional short-term spikes of oxygen keep the cells alive and active. ...> Full Article
