Nanopatch for the heart
When you suffer a heart attack, a part of your heart dies. Nerve cells in the heart's wall and a special class of cells that spontaneously expand and contract � keeping the heart beating in perfect synchronicity � are lost forever. Surgeons can't repair the affected area. It's as if when confronted with a road riddled with potholes, you abandon what's there and build a new road instead........



Antidepressants linked to thicker arteries
Antidepressant use has been associated with thicker arteries, possibly contributing to the risk of heart disease and stroke, in a study of twin veterans. The data is being presented Tuesday, April 5 at the American College of Cardiology meeting in New Orleans. Depression can heighten the risk for heart disease, but the effect of antidepressant use revealed by the study is separate and independent from depression itself, says first author Amit Shah, MD, a cardiology fellow at Emory University School of Medicine. The data suggest that antidepressants may combine with depression for a negative effect on blood vessels, he says. Shah is a researcher working with Viola Vaccarino, MD, PhD, chair of the Department of Epidemiology at Emory's Rollins School of Public Health........



Migraine headaches and a common heart defect
Cincinnati, OH, March 31, 2011 -- Roughly 15% of children suffer from migraines, and approximately one-third of these affected children have migraines with aura, a collection of symptoms that can include weakness, blind spots, and even hallucinations. Eventhough the causes of migraines are unclear, a newly released study soon to be published in The Journal of Pediatrics suggests a correlation between migraine headaches in children and a heart defect called patent foramen ovale, which affects 25% of people in the U.S........



Walnuts are top nut for heart-healthy antioxidants
A new scientific study positions walnuts in the No. 1 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 here today at the 241st National Meeting and Exposition of the American Chemical Society, researchers presented an analysis showing that walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut........



Load Up on Fiber Now
A newly released study from Northwestern Medicine shows a high-fiber diet could be a critical heart-healthy lifestyle change young and middle-aged adults can make. The study found adults between 20 and 59 years old with the highest fiber intake had a significantly lower estimated lifetime risk for cardiovascular disease in comparison to those with the lowest fiber intake........



13 new genes to heart disease
Insight into the complex biological mechanisms that cause heart disease has taken a major step forward with the discovery of 13 new genes that increase the risk of coronary artery disease (CAD). The influence of the majority of the new genes is independent of other established risk factors, suggesting new, unsuspected causes of CAD. The discovery more than doubles the number of genes known to affect the progression of heart disease........



Stem cells to repair a child's heart
Visionaries in the field of cardiac therapeutics have long looked to the future when a damaged heart could be rebuilt or repaired by using one's own heart cells. A study reported in the recent issue of Circulation, a scientific journal of the American Heart Association, shows that heart stem cells from children with congenital heart disease were able to rebuild the damaged heart in the laboratory........



Heart failure patients admitted to general wards
Heart failure patients admitted to general wards are twice as likely to die as those admitted to cardiology wards, shows a national audit of the therapy of the condition, published online in the journal Heart Women fared worse than men when it comes to appropriate investigations and therapy, the findings suggest, eventhough death rates were similar........



Kidney gene and heart failure risk
Researchers have identified the first DNA sequence variant common in the population that is not only linked to an increased risk of heart failure, but appears to play a role in causing it. The variant, a change in a single letter of the DNA sequence, impairs channels that control kidney function. "It's not a heart gene," says Gerald W. Dorn II, MD, the Philip and Sima K. Needleman Professor of Medicine at Washington University School of Medicine in St. Louis and a lead investigator on the study. "It's a kidney gene. This protein is not even expressed in the heart. Nobody has previously considered that kidney-specific gene defects might predispose you to heart failure"........



Reduction in salt consumption recommended
The American Heart Association today issued a call to action for the public, health professionals, the food industry and the government to intensify efforts to reduce the amount of sodium (salt) Americans consume daily. In an advisory, published in Circulation: Journal of the American Heart Association, the association sets out the science behind the American Heart Association's recommendation for the general population, which is to consume no more than 1500 milligrams (mg) of sodium a day because of the harmful effects of sodium - elevated blood pressure and increased risk of stroke, heart attacks and kidney disease. Elevated blood pressure (hypertension) is a major public health problem - approximately 90 percent of all Americans will develop high blood pressure over their lifetime........



Berries may reduce high blood pressure
Hypertension - or high blood pressure - is a main cardiovascular diseases worldwide. It leads to stroke and heart disease and costs more than $300 billion each year. Around a quarter of the adult population is affected globally - including 10 million people in the UK and one in three US adults. Published next month in the American Journal of Clinical Nutrition, the new findings show that bioactive compounds in blueberries called anthocyanins offer protection against hypertension. Compared with those who do not eat blueberries, those eating at least one serving a week reduce their risk of developing the condition by 10 per cent........



Poor response to anti-anemia drug predicts higher risk
Patients with diabetes, kidney disease and anemia who don't respond to therapy with an anti-anemia drug have a higher risk of cardiovascular disease or death, scientists at UT Southwestern Medical Center have found. The results suggest that testing such patients' responsiveness to the drug and keeping blood iron levels a little low might reduce their risk, said Dr. Robert Toto, professor of internal medicine and clinical sciences and a senior author of the study, which appeared in the New England Journal (NEJM).......



Sleep apnea and heart disease
People with obstructive sleep apnea (OSA), a sleep disorder linked to obesity, have more non-calcified or "bad" plaque in their coronary arteries, as per a research studypresented today at the annual meeting of the Radiological Society of North America (RSNA). "Our study reveals that individuals with obstructive sleep apnea are prone to developing an aggressive form of atherosclerosis that puts them at risk for impaired blood flow and cardiovascular events," said U. Joseph Schoepf, M.D., professor of radiology and medicine and director of cardiovascular imaging at the Medical University of South Carolina in Charleston, S.C........



Cardiac wakeup call for Canadian kids
Poor sleep patterns and lack of proper sleep could be threatening thousands of Canadian adolescents with premature heart disease and stroke, warns Heart and Stroke Foundation researcher Dr. Brian McCrindle, a pediatric heart specialist at the Hospital for Sick Children in Toronto. "Sleep disorders in kids are on the increase. They are marching hand in hand with other increasing cardiovascular risk factors such as overweight and obesity, lack of physical activity, a poor diet, and high levels of unhealthy cholesterol," Dr. McCrindle today told the Canadian Cardiovascular Congress 2010, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society........



No heart benefits for folic acid supplements
Use of folic acid supplements appears to lower blood levels of the amino acid homocysteinetheorized to be a risk factor for heart and blood vessel diseasebut does not appear to be linked to reduced rates of cardiovascular events, cancer or death over a five-year period, as per a meta-analysis of previously published studies in the October 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals........
