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.

A more accurate method for measuring blood levels of endothelial progenitor cells

A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists.

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

Transplanting a pair of kidneys with limited function into one patient may offer one solution to short supply of donated kidneys

Transplanting a pair of kidneys with limited function into one patient can be just as successful as the standard procedure in which a patient receives a single kidney, according to new research at Wake Forest University Baptist Medical Center.

Health disparities in heart attack hospital transfer patterns

Older, female and minority patients rushed to community hospitals with acute heart attacks are less likely to be transferred to a larger hospital that offers procedures to immediately open clogged arteries, Duke University Medical Center cardiologists have found.

Influenza-associated hospitalization in a subtropical city

A new study shows that tropical and subtropical countries suffer far more illness and death during flu outbreaks than previously imagined, with both hospital admissions and deaths rising considerably during a flu outbreak.

Anxiety restricts blood flow in some patients

The fear of public speaking might cause some people to do more than just break out in a cold sweat and battle stomach-churning butterflies - it could prove to have consequences for their heart health.

Drug-eluting stents best treatment for managing coronary restenosis

In the first published trial of its kind, a multi-center clinical study has shown that drug-eluting stents outperform the current "gold standard" radiation treatment in managing coronary restenosis and in preventing further clogging of coronary arteries.
