Researchers followed 1,927 men and 2,495 women aged 40 and over who had no heart disease at their baseline sleep study. After eight and a half years they concluded obstructive sleep apnea is associated with higher risk of heart failure in men; the coronary heart disease link was equivocal.

Testosterone therapy raises heart risk
Researchers halted a six-month trial of testosterone gel in 209 elderly men with poor mobility after 23 in the treatment group suffered heart, breathing and skin problems, against five on placebo. Strength and mobility improved, but the risks ended the study early.
Food
Cholesterol, eggs raises heart risk in older people
Among 1,941 older adults followed nine years, dietary fat was not linked to cardiovascular events, but those in the top third for cholesterol intake had 47 percent higher risk, and people eating more than three eggs a week were 68 percent more likely to have a heart attack, coronary death or stroke.
Food
Processed meat linked to elevated risk of heart disease, diabetes
A Harvard meta-analysis in Circulation linked each 50 grams of processed meat eaten daily, about one hot dog, with 42 percent higher heart disease risk and 19 percent higher diabetes risk. Unprocessed meats showed no such link, and researchers suspect the salt and nitrate preservatives.
Food
How does sugar raise heart disease risk?
A JAMA study led by Miriam Vos found high added-sugar intake tracked with worse blood lipids, including an unfavorable triglyceride-to-HDL ratio. It was not a trial, so it cannot show sugar caused the risk. Hu and Malik point to glycemic load and fructose as possible mechanisms.
Chemical
Saturated Fat is NOT the Cause of Heart Disease
Mercola highlights an analysis in the American Journal of Clinical Nutrition pooling 21 studies that found no clear evidence higher saturated fat intake led to higher risk of heart disease or stroke, and traces the case against saturated fat to Ancel Keys in 1953.

What You Need to Eat to Fight Heart Disease
The CDC's American Heart Month advice tells women to eat more fruit and vegetables and limit sugar, salt and fat; one observer wants specifics. A roundup of earlier studies follows, including vitamin K2 tied to 9 percent lower coronary heart disease risk per 10 micrograms a day.
Supplements
Herbal remedies interfere with drugs for heart disease
Mayo Clinic cardiologists warn that St. John's wort, ginkgo biloba, garlic and even grapefruit juice can blunt or amplify heart medications, risking bleeding or serious arrhythmia. They say elderly patients taking several drugs at once face the greatest danger.

Childhood Cancer Survivors at Increased Risk of Heart Disease
A study of 14,000 pediatric cancer survivors found cardiac problems surfacing as long as 30 years after treatment; lead author David Mulrooney urges ongoing monitoring. An Emory analysis of 8,000 survivors found them 10 times likelier than others to develop cardiovascular disease.
Lifestyle
Early menstruation linked to higher heart disease risk
British researchers report that women who began menstruating before age 12 faced a 23 percent higher risk of heart disease, a 28 percent higher risk of dying from heart attack or stroke, and a 25 percent higher risk of dying from cancer.

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.
Disease
Pediatric cancer survivors at risk of dying from heart disease
A BMJ study compared 14,358 five-year survivors of childhood cancer with 3,899 siblings and found survivors face higher rates of heart failure, heart attack, heart inflammation and valve abnormalities as late as 30 years after treatment, even at lower drug and radiation doses than expected.

Does High Cholesterol REALLY Cause Heart Disease?
Uffe Ravnskov says he never believed the cholesterol theory of atherosclerosis, calling the idea that slightly raised blood cholesterol kills as silly as claiming yellow fingers cause lung cancer. He recounts leaving academic nephrology after exposing a colleague's fraudulent paper.
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.
Healthcare
Low-dose radiation can cause heart disease and stroke too
Imperial College London researchers built a mathematical model, published in PLoS Computational Biology, predicting that higher radiation doses raise cardiovascular risk, in line with studies of nuclear workers. If the mechanism holds, risks from medical and dental x-rays may be underestimated.
Nutrition
Do phytosterol reduce risk of heart disease? and more!
An AICR Q&A: 2 grams of phytosterols a day can lower LDL cholesterol about 10 percent in people with high cholesterol, though reaching that usually takes fortified products, and there is no known benefit at healthy levels. The writer knows of no research tying whey to prostate cancer.
Vitamins
Sunshine vitamin may help prevent heart attack
Harvard researchers compared 454 men who had a heart attack or fatal heart disease with 900 who did not, and found men deficient in vitamin D faced 2.42 times the risk of those with sufficient levels. The authors caution that the sunlight pattern is not proof of cause.
