The seasonal flu vaccine is associated with a 19% reduction in the rate of first heart attack and early vaccination in the fall further increases the benefits, found a study published in CMAJ (Canadian Medical Association Journal).

Scientists at the University of Pittsburgh School of Medicine went on a molecular fishing trip and netted a catch of new mediators that not only can explain how omega-3 fatty acids reduce inflammation, but also hint at novel treatments for a host of diseases linked to inflammatory processes.

A protein found in cells throughout the body must be present in a specific set of neurons in the brain to prevent weight gain after chronic feeding on high-calorie meals, new findings from UT Southwestern Medical Center researchers suggest.

Doctors have warned that people should try to avoid taking dissolving, fizzy paracetamol (acetaminophen) that contains salt, following findings from a large study that...

A new scientific study positions walnuts in the number one slot among a family of foods that lay claim to being among Mother Nature's most nearly perfect packaged foods: Tree and ground nuts. In a report given in Anaheim, California at the 241st National Meeting & Exposition of the American Chemical Society on March 27, scientists presented an analysis showing that walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut.

It seems that while the practice of bloodletting throughout history had little or no effect on most diseases, and the practice was abandoned in the 19th century, new research published in BioMed Central's open access journal BMC Medicine demonstrates that blood donation has real benefits for obese people with metabolic syndrome. Two sessions of bloodletting were enough to improve blood pressure and markers of cardiovascular disease.

A new study led by a University of California, Berkeley, researcher could give women a little extra motivation to visit their dentist more...

University of Minnesota Medical School researchers have collaborated with the School of Public Health and discovered an enzyme that, when found at high levels and alongside low levels of HDL (good cholesterol), can dramatically reduce the risk of cardiovascular disease.

Postmenopausal women may be at higher risk of having a stroke than they think. A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke -- such as high cholesterol -- are not as accurate at predicting risk in postmenopausal women as previously thought.

For many patients, cholesterol-lowering statin drugs can reduce the risk of strokes as well as heart attacks. But in a review article, Loyola University Health System neurologists caution that statins may not be appropriate for cetain categories of patients who are at risk for stroke.

A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health suggests that hyperglycemia (high blood sugar) injures the heart, even in patients without a history of heart disease or diabetes. Researchers found that elevated levels of glycated hemoglobin (HbA1c), a marker for chronic hyperglycemia and diabetes, were associated with minute levels of the protein troponin T (cTnT), a blood marker for heart damage.

Agricultural Research Service (ARS)-funded scientists have reported new reasons for choosing "heart-healthy" oats at the grocery store. Nutritionist Mohsen Meydani, director of the Vascular Biology Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at...
