Should healthy people take statins too?

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. 
Statins Lower Blood Marker for Prostate Cancer

THURSDAY, Oct. 30 (HealthDay News) -- A new study shows that men who take cholesterol-lowering drugs called statins have lower blood levels of prostate-specific antigen (PSA), a biomarker for prostate cancer risk.
That drop in PSA levels doesn't necessarily mean the drugs protect against disease, however, researchers say.
But it's possible that statins may offer some protection against the disease, said Dr. Robert Hamilton, one author of the report in the Oct. 28 issue of the Journal of the National Cancer Institute
Flu Shots May Cut Risk of Blood Clots Forming in Veins

Flu shots may reduce the risk of blood clots forming in veins by 26 percent, according to research presented at the American Heart Association’s Scientific Sessions 2008.
“Our study suggests for the first time that vaccination against influenza may reduce the risk of venous thrombotic embolism (VTE),” said Joseph Emmerich, M.D., Ph.D., lead author of the study and professor of vascular medicine at the University Paris Descartes and head of the INSERM Lab 765, which investigates thrombosis. “This protective effect was more pronounced before the age of fifty-two years
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.
"I think that this is clearly significantly better than what we have now," Dr. W
Genetic study undermines case for CRP as cause of vascular disease

Copenhagen, Denmark- Is C-reactive protein (CRP) a promoter of cardiovascular disease or simply a marker of increased cardiovascular risk? Probably the latter, according to the latest study to address the question, in which four gene variants tied to sharply increased CRP levels were shown not to be associated with an elevated CV-event risk
French Try Plane Technology in Artificial Heart

In the race to build a better artificial heart, French scientists have turned to technology from satellites and airplanes to create a heart that they say responds better to the human body. So far, the new device, shown at a news conference in Paris on Monday, has only been tested in animals. Its makers hope it might one day help people survive without needing a human heart transplant.
The maker of this artificial heart is a subsidiary of the European Aeronautic and Space Defense Company (EADS), but this isn't a matter of fluid dynamics
Industry shifts focus to immunology and cancer

Economic factors, including competition from generic drugs, is hitting even the big pharmaceutical companies hard, reports Nature. In 2010, Pfizer's Lipitor enters the public domain. For these reasons, the larger companies are narrowing the focus of their research, hitting fewer diseases. They're also working on fewer primary care drugs and more drugs that would be prescribed by specialists, such as cancer drugs.
"When Wyeth Pharmaceuticals announced last week that it would cut some of its research and development (R&D) programs in women's health, the decision seemed counterintuitive
Mini heart attack best treated like the big one

People who show up at a hospital with mild heart attack symptoms, but only ambiguous scores on medical tests, might still warrant emergency treatment, according to research presented at a meeting of the American Heart Association.
Starving tumors of blood vessels may not be the way to go

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
