Study finds drug eluting stents as effective as vascular brachytherapy in preventing restenosis
After angioplasty is performed to widen clogged arteries, surgeons frequently use tiny wire-mesh tubes called stents to keep blood vessels open. But despite stenting, scar tissue can form to create new blockages -- a process called in-stent restenosis (ISR). more

Study says rare allergic reactions to drug-eluting stents may raise risk for heart attack
Stents, tiny wire mesh tubes, are routinely used to prop arteries open after angioplasty clears them of potentially heart attack causing plaque. In the past, stented arteries often eventually closed up again with fatty deposits, a process called restenosis. However, since their FDA approval in 2003, stents coated with sirolimus (a pharmaceutical agent that prevents excess tissue growth) have been shown to greatly reduce restenosis. But some people suffer from rare, allergic-type reactions to the sirolimus-eluting stents (SES).  more

Serum sodium level is a major predictor of a poor prognosis for heart failure patients
Research presented today at the American College of Cardiology's Scientific Sessions in Orlando pinpoints a major marker of a poor prognosis for heart failure, hyponatremia, or a lower than normal concentration of serum or blood sodium. Researchers found that hyponatremia, which is found in almost a quarter of patients with severe heart failure, doubled death rates within 60 days of hospital discharge. Serum sodium levels are easily measured through routine blood tests. more

Statement on the findings of the Women's Health Study
The Women's Health Study is the first large clinical trial to study the use of low-dose aspirin to prevent heart attack and stroke in women. The 10-year randomized, double-blind, placebo-controlled study was conducted among nearly 40,000 healthy women age 45 and older.  more

Stroke warning signs often occur hours or days before attack
Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.  more

Cockroach allergens have greatest impact on childhood asthma in many US cities
New results from a nationwide study on factors that affect asthma in inner-city children show that cockroach allergen appears to worsen asthma symptoms more than either dust mite or pet allergens. This research, funded by the National Institute of Environmental Health Sciences (NIEHS) and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is the first large-scale study to show marked geographic differences in allergen exposure and sensitivity in inner-city children. Most homes in northeastern cities had high levels of cockroach allergens, while those in the south and northwest had dust mite allergen levels in ranges known to exacerbate asthma symptoms.  more

How effective are herbal supplements in reducing illnesses in children?
The use of herbal supplements in women is increasing. Many mothers may also be giving herbal supplements to their children to treat or prevent various illnesses, including asthma, hyperactivity, colds, and respiratory infections.  more
