Psychological wellbeing has biological consequences

An experimental investigation by Carol Ryff and associates (University of Wisconsin), published in the March issue of the journal of Psychotherapy & Psychosomatics, underscores the biological consequences of psychological well-being.

Hormone C-type natriuretic peptide protects the heart muscle from thickening abnormally

When the heart is weakened, it tries to compensate for its impaired pumping function through an enlargement of the heart muscle cells. Physicians speak in this case of cardiac hypertrophy, abnormal enlargement of the heart.

Social isolation and low mood accelerate coronary disease in women

A study published in the 2006 March issue of Psychotherapy & Psychosomatics by a Swedish group of investigators points to the effects of social isolation and low mood on the progression of coronary disease.

Australian researchers find key 'go-betweeen' in heart disease

Medical researchers at the University of New South Wales (UNSW) - Australia, have shed light on a little-known mechanism involved in the thickening of arteries, a process associated with heart disease.

Drink up that vino - it stops your teeth falling out!

Red wine contains antioxidants known as polyphenols, which are already believed to reduce cholesterol but are now also thought to prevent gum disease.

Best seller Lipitor shown to improve kidney function

According to drug maker Pfizer it's top selling product worldwide, the cholesterol lowering medication Lipitor (Atorvastatin) has been shown to improve kidney function in patients with heart disease.

Filter more effective than diuretics for heart failure

Researchers in the U.S. say that filtering the blood works better than diuretic drugs to remove excess fluid in patients admitted to hospital for heart failure.

Aspirin still the best for reducing the heart attack risk

New research has revealed that the addition of the blood-thinning drug Plavix to a daily dose of aspirin does not lower the risk of death, heart attack or stroke in high-risk patients.

B vitamins and folic acid don't cut the risk of further heart attacks

Scientists have found that levels of the amino acid homocysteine may be high in people destined for a heart attack or stroke, and some studies in the past have linked homocysteine to an increased risk of heart disease.

Mental stress induced ischemia more common than thought

Even when heart disease patients can pass stress tests done on a treadmill or with chemical stressors after treatment, their hearts may still suffer silent ischemia during mental stress, according to a new study in the Mar. 7, 2006, issue of the Journal of the American College of Cardiology.

Scientists exploit novel route to reverse enlarged hearts in obese mice

Working on genetically engineered obese mice with seriously thickened hearts, a condition call cardiac hypertrophy, scientists at Johns Hopkins have used a nerve protection and growth factor on the heart to mimic the activity of the brain hormone leptin, dramatically reducing the size of the heart muscle.

RvE1 protects from inflammation and bone loss in experimental periodontitis

Gum disease is initiated by bacteria populating dental plaque and may eventually result in tissue and tooth loss.

Elderly people should not be afraid to exercise

Older people generally have to work harder than younger people to walk as fast or do other exercise, but some of the difference may be due to reduced exercise efficiency, which can be reversed with training.

Sirolimus-releasing stents more effective than vascular brachytherapy for treating restenosis within a stent

David R. Holmes, Jr., M.D., of Mayo Clinic, Rochester, Minn., and colleagues with the SISR trial compared the use of vascular brachytherapy (VBT - intra-coronary radiation therapy) with implantation of the sirolimus-eluting stent for the treatment of restenosis occurring within a previously placed bare-metal stent

Using a growth factor to stimulate production of circulating endothelial progenitor cells improves cell production and mobility in arterial disease

Using a growth factor to stimulate production of circulating endothelial progenitor cells increases the numbers of these vascular regenerative cells, improves mobility, and potentially could improve blood vessel function in patients with peripheral arterial disease (PAD).

Link between childhood exposure to tobacco smoke and Streptococcus pneumoniae

Many of the medical risks associated with smoking, such as cancer, emphysema and heart attacks, are well-known to physicians and the general public.

Stents that release the drug paclitaxel to treat stenosis more effective than radiation therapy

Insertion of stents that release the drug paclitaxel to treat stenosis within an implanted bare-metal stent in a coronary artery reduces the risk of subsequent re-narrowing within the stent, when compared with treatment using intra-coronary radiation
