Researchers at the University of Houston gave hypertensive rats resveratrol in drinking water for ten weeks. Compared with untreated rats, the treated animals had lower blood pressure, less oxidative stress and better endothelial function - a possible route by which red wine might protect arteries.

Heart & Blood
To Tackle Heart Disease, Diet Changes Beat Drugs Any Day
Nutrition
You can lower cholesterol, but can't cut cardiovascular risk
A trial halted 18 months early found that adding niacin to statins in 3,412 high-risk patients raised HDL and lowered LDL but did not cut heart attacks, strokes or hospitalizations for acute coronary problems or revascularization.
Vitamins
Calcium and vitamin D: Is it heart smart ?
A BMJ reanalysis of the Women's Health Initiative calcium and vitamin D trial, pooled with eight other studies, reports that calcium supplements with or without vitamin D can raise the risk of cardiovascular events such as heart attack. The original trial of 36,282 women found no such rise.
Disease
Cardiovascular disease: Put your heart into preventing it
The Heart Truth campaign and its Red Dress symbol target women aged 40 to 60, when heart disease risk starts rising. Eight million U.S. women live with heart disease and 435,000 have heart attacks a year, yet nearly half say they would not call 911 during symptoms.
Drug
Chest radiation boosts death risk from heart disease
A study in the Journal of the American College of Cardiology found women who received chest radiation for breast cancer faced up to a 76% higher risk of dying from heart disease over 28 years than untreated women. Radiation's vascular damage is rarely publicized, the piece notes.
Biological
Listeria Has Acquired Ability to Attack the Heart
A brief note that Listeria monocytogenes, found in raw milk, soft-ripened cheeses and ready-to-eat cold cuts and able to thrive under refrigeration, has strains that researchers say appear to have gained an enhanced ability to invade and infect the heart.
Lifestyle
Managing stress could reduce heart disease
In a Swedish trial of 362 patients discharged within the previous year, those assigned cognitive behavioral therapy had a 41 percent lower rate of fatal and non-fatal cardiac events, 45 percent fewer recurrent heart attacks and 28 percent lower death rates than usual-care patients.
Food
Green Tea Helps Prevent Heart Disease
A meta-analysis of 18 studies tied each daily cup of green tea to 10% lower coronary artery disease risk, and the heaviest green tea drinking to 28% lower risk. The authors found no protective role for black tea and call the green tea association tentative and observational.
Disease
Lowering blood pressure is heart healthy
A Hypertension study followed 9,357 adults in 11 countries for over 11 years and estimated that almost 36 percent of heart disease in women and 24 percent in men is preventable. Dr. Staessen says cutting systolic pressure by 15 mm Hg helps roughly twice as many women as men.
Heart & Blood
Fruit, vegetables cut ischemic heart disease risk
In EPIC data on more than 300,000 Europeans, with 1,636 ischemic heart disease deaths, those eating 640 grams of fruit and vegetables a day were 22% less likely to die of it than those eating under 240 grams, with each extra portion linked to 4% lower risk.
Diet
Mediterranean diet may prevent diabetes, heart disease, depression
A New England Journal of Medicine trial found that patients with depression plus diabetes or heart disease did better under TEAMcare, in which a nurse tracked blood sugar, blood pressure, cholesterol and mood alongside their doctors. At one year they were less depressed and better controlled.
Healthcare
Nurses help patients with depression, diabetes or heart disease
In a randomized trial of 224 patients with depression plus diabetes or heart disease, those whose care a nurse coordinated with their physicians were less depressed and had better blood sugar, cholesterol and blood pressure at one year. The two-year program cost $1,224 per patient.
Minerals
Kidney disease patients should avoid foods with high phosphorus
Eight chronic kidney disease patients had lower blood and urine phosphorus after a week of vegetarian eating than after a meat-based diet matched for protein and phosphorus. Researchers suspect plant phosphorus is less bioavailable, but say longer studies are needed.
Lifestyle
Passive smoking causes more heart disease deaths than lung cancer deaths
WHO researchers estimate secondhand smoke kills about 600,000 people a year worldwide, including 379,000 from heart disease and 21,400 from lung cancer. Two-thirds of those deaths occur in Africa and south Asia, and about 165,000 are children.
Drug
HIV drugs boost risk of diabetes and heart disease
Washington University researchers report in the Journal of Biological Chemistry that first-generation protease inhibitors such as ritonavir block a protein that carries blood sugar into cells, leaving sugar in the blood, a marker of diabetes, in patients being treated for HIV.
Food
Eating vegetables cuts heart disease risk
Following 20,069 Dutch adults for 10 years, Griep's team found those eating more than 475 grams of fruit and vegetables a day were 36% less likely to develop coronary heart disease than those eating under 241 grams. Raw intake above 262 grams tracked with 30% less.
Disease
Trying to Manage Heart Disease Through Physical Activity?
A CDC study found 57 percent of adults with heart disease also have arthritis, and 29 percent of those with both are physically inactive, against 21 percent with heart disease alone. Joint-friendly activity such as walking, swimming or biking may help them manage both conditions.
