Sudden cardiac death -catastrophic and unexpected fatal heart stoppage -- is more likely to occur shortly after waking in the morning and in the late night. In a report in the journal Nature, an international consortium of researchers that includes Case Western Reserve University School of Medicine in Cleveland and Baylor College of Medicine explains the molecular linkage between the circadian clock and the deadly heart rhythms that lead to sudden death.

Excessive consumption of phosphate is damaging to health. Therefore, food that contains phosphate additives should be labeled, as recommended by Eberhard Ritz and coauthors in their article in the current issue of Deutsches Ärzteblatt International [Dtsch Arztebl Int.]

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.

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.

In the largest and longest head-to-head comparison of two anti-clotting medications, warfarin and aspirin were similar in preventing deaths and strokes in heart failure patients with normal heart rhythm, according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2012.

Eating food fried in olive or sunflower oil is not linked to heart disease or premature death, finds a paper published in the British Medical Journal online (bmj.com). The authors stress, however, that their study took place in Spain, a Mediterranean country where olive or sunflower oil is used for frying...

Research from Queen Mary, University of London suggests that omega-3 fatty acids, which are found in fish oil, have the potential to protect nerves from injury and help them to regenerate. When nerves are damaged because of an accident or injury, patients experience pain, weakness and muscle paralysis which can leave them disabled, and recovery rates are poor.

In a study that enrolled nearly 30,000 apparently healthy men and women, those who had an increase in their resting heart rate over a 10-year period had an increased risk of death from all causes and from ischemic heart disease, according to a study in the December 21 issue of JAMA.

Heart disease affects men and women in different ways. In women, symptoms of burgeoning heart disease are often more insidious, but when a heart attack strikes, it is more lethal than it is in men. Roughly 25 percent of men will die within a year of their first heart attack, but among women, 38 percent will die. Women are twice as likely as men to have a second heart attack within 6 years...

A long-held mantra suggests that you can't change your family, the genes they pass on, or the effect of these genes. Now, an international team of scientists, led by researchers at McMaster and McGill universities, is attacking that belief.

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.

Rheumatoid arthritis (RA) sufferers are at an increased risk of dying due to cardiovascular disease. A new five year study published in BioMed Central's...
