No, this isn't a reminder that today -- the 12th day of Christmas -- is the traditional day to pack away the tree ornaments. These brilliant orbs are actually a layer of fluorescently stained muscle cells designed to encourage the growth of stem cells that may one day replace pacemakers in children and keep young hearts beating on time, according to Doug Cowan, an assistant professor of anesthesia at Children's Hospital Boston. 
Viagra's other talents: Helping a signaling protein shield the heart from high blood pressure damage

Johns Hopkins and other researchers report what is believed to be the first direct evidence in lab animals that the erectile dysfunction drug sildenafil amplifies the effects of a heart-protective protein.

A research group from Iran investigated the prevalence of gluten-sensitive enteropathy (GSE) in a large group of patients with iron deficiency anemia (IDA) of obscure origin. They found that there is a high prevalence of GSE in patients with IDA of obscure origin. A gluten-free diet can improve anemia in GSE patients who have mild duodenal lesions without villous atrophy.
Smoking ups risk of common heart rhythm problem

Offering yet another reason to never start smoking, a new study finds that both current and former smokers run an elevated risk of the heart rhythm disorder atrial fibrillation.
The condition, also known as AF, is the most common heart arrhythmia in the U.S., affecting about two million people. During an episode of AF, abnormal electrical activity in the heart causes its upper two chambers to beat in a rapid, uncoordinated rhythm; the arrhythmia itself is not life-threatening, but over time AF can contribute to stroke or heart failure in some people
Gene Ups Risk for Those on Blood-Thinner Plavix

A gene variation can make younger heart attack patients more prone to another heart attack, death or other heart problems if they receive the anti-clotting drug Plavix, a trio of new studies finds.
Skimping on sleep linked to hardened arteries

Just one extra hour of sleep a day appears to lower the risk of developing calcium deposits in the arteries, a precursor to heart disease, U.S. researchers said on Tuesday. The finding adds to a growing list of health consequences - including weight gain, diabetes and high blood pressure - linked to getting too little sleep
Lack of Sleep Linked to Heart Problems

No one likes to walk into work after just a few fitful hours of sleep. But now there's evidence that not getting enough sleep may have more serious consequences than dark circles under your eyes the next morning. Researchers at the University of Chicago report in the Journal of the American Medical Association that too little sleep can promote calcium buildup in the heart arteries, leading to the plaques that can then break apart and cause heart attacks and strokes.
Preventing a broken heart: Research aims to reduce scarring from heart attacks
piggy submitted, created time 3 weeks 3 days (www.eurekalert.org)
A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.
Now researchers have identified a key molecule involved in controlling excessive scar tissue formation in mice following a heart attack. When they stopped the scarring from occurring, the scientists found that the animals' heart function greatly improved following the injury

Blood Pressure Pill Combo More Effective Than Diuretics

A pill that contains two blood pressure drugs was more effective than a diuretic-based strategy in reducing the risk of serious cardiovascular problems and death in people with high blood pressure, according to a study that included more than 11,000 patients in the United States, Sweden, Norway, Denmark and Finland.
The patients took either a tablet containing benazepril (an ACE inhibitor) and amlodipine (a calcium channel blocker) or a tablet that contained benazepril and hydrochloro-thiazide, a type of diuretic (water pill)
A Little Wine Boosts Omega-3 in the Body: Novel Mechanism for a Healthier Heart Found

Moderate alcohol intake is associated with higher levels of omega-3 fatty acids in plasma and red blood cells. This is the major finding of the European study IMMIDIET that will be published in the January issue of the American Journal of Clinical Nutrition.
The study suggests that wine does better than other alcoholic drinks. This effect could be ascribed to compounds other than alcohol itself, representing a key to understand the mechanism lying behind the heart protection observed in moderate wine drinkers
Lifestyle may link depression and heart disease

The long-standing connection between depression and heart problems might be traceable to the fact that depressed people are less physically active than others, a new study of heart patients shows. A greater tendency in depressed people to smoke and to fail to take medications regularly may also play a role, researchers report in the Nov. 26 Journal of the American Medical Association
Should healthy people take statins too?
sea-maid submitted, created time 1 month 3 weeks (www.nature.com)
The results of a study examining whether a potent cholesterol-lowering drug decreases the risk of heart disease are out. Rosuvastatin was given to 17,802 seemingly healthy people, and their chance of developing heart problems plummeted. The results, published in the New England Journal of Medicine, have revealed a number of questions about how to prevent heart attacks. Is exercise and a low-fat diet enough, or should large swathes of the population be prescribed preventative medication? Nature News gets to the heart of the matter.
Starving tumors of blood vessels may not be the way to go
piggy submitted, created time 1 month 3 weeks (www.sciencedaily.com)
Dense networks of blood vessels thought to spur cancer’s growth could actually hinder rather than promote tumor progression, according to a new study at the University of California, San Diego.
The findings partly explain why drugs designed to treat cancer by strangling its blood supply have been disappointing when used alone and why those treatments are more effective when combined with traditional chemotherapy
New test to identify heart failure in emergency medicine found superior to current standards

A new blood test to identify heart failure patients in most dire need of treatment when they turn up at an emergency room complaining of shortness of breath proved better than current tests, according to results of a study unveiled on Tuesday.
The pivotal trial of the test developed by privately held German company Brahms AG succeeded in its goal of demonstrating superiority over tests considered the current gold standard.
