A review of 52 papers covering 3 million patients found the shortest people in a population, under about 5 feet 3, were 1.5 times more likely to have heart problems than those 5 feet 9 and over. The authors stress modifiable risks matter more; smokers face four times the risk.

Robert Culp Dies of Heart Attack, What You Need to Know
Culp, 79, collapsed outside his Hollywood home Wednesday; reports differ on whether he died from a fall or a heart attack. The piece then covers heart attack basics: blocked arteries starve heart muscle of oxygen, and about 1.1 million Americans have one yearly, 460,000 fatally.

Big Star singer Alex Chilton dead, what you need to know
Alex Chilton, the singer and guitarist behind the Box Tops and Big Star, died Wednesday at 59 after being rushed to a New Orleans emergency room, probably of a heart attack, the Memphis Commercial Appeal reported. The piece goes on to review heart attack symptoms and causes.

Green tea cuts risk for heart disease and stroke
A Circulation Journal study of 520 Chinese patients having their first coronary arteriography linked green tea drinking to a 38 percent lower risk of coronary atherosclerosis. Men using 125 grams or more of leaves a month had 64 percent lower risk; no link appeared among the women.
Heart & Blood
Can Alcohol Really Protect Your Heart?
A study reported that men who drank moderate, high and very high amounts of alcohol had lower coronary heart disease risk, but other scientists called it flawed and said it should not encourage anyone to drink more. Dr. Mercola treats it as an example of bad science.

High fat low carb diet may raise heart risk
In an 8-week trial of 24 overweight and obese adults, a 60 percent fat, 20 percent carbohydrate diet matched a low-fat, high-carb diet on weight loss and glucose metabolism, but researchers concluded its heart disease risks outweighed the benefits.

Heart failure linked to gene variant affecting vitamin D activation
Among 617 patients from the Marshfield Clinic Personalized Medicine Project, those with high blood pressure who carried a variant in CYP27B1, a gene needed to activate vitamin D, were twice as likely to have congestive heart failure. Co-author Robert Simpson says larger studies must confirm it.
Heart & Blood
High salt intake boosts stroke risk
Pooling 13 studies of 177,025 people, Italian researchers linked higher salt intake to 23 percent higher stroke risk and 14 percent higher risk of cardiovascular disease. They say imprecise measurement of salt intake likely means these effects are underestimated.
Heart & Blood
Trans fat raises risk of sudden cardiac death in women
In the Nurses' Health Study of 86,762 women, those already diagnosed with coronary heart disease who ate the most trans fat were 224 percent more likely to die of sudden cardiac death; across the wider analysis the researchers found no significant association.
Heart & Blood
Vitamin D cuts risk of cardiovascular disease
Among 27,686 patients aged 50 and older with no prior cardiovascular disease, those with very low vitamin D were 77 percent more likely to die, 45 percent more likely to have coronary artery disease and 78 percent more likely to have a stroke than those with normal levels.

Study: Virus may trigger high blood pressure
Harvard's Clyde Crumpacker found that the herpes virus cytomegalovirus causes lasting inflammation in blood vessels that over time may trigger high blood pressure, and that 30 percent of CMV-exposed mice on a high-fat diet showed atherosclerosis. He suggests antivirals may one day treat it.
Heart & Blood
Fructose vs. glucose debate ignited by study
In a 10-week test of 32 obese people, those drinking fructose-sweetened beverages for a quarter of their daily calories gained the same weight as the glucose group but added more belly fat, became somewhat insulin resistant and had higher blood lipids.
Heart & Blood
Vitamin D may prevent heart failure
Robert U. Simpson and colleagues treated heart-failure-prone rats on a high-salt diet with calcitriol for 13 weeks. The treated rats showed lower heart weight, smaller left ventricles and lower levels of several key heart-failure predictors than untreated rats.
