Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Blood cholesterol levels predict risk of heart disease due to hormone therapy

A new analysis of a subgroup of participants in the Women's Health Initiative (WHI) hormone therapy clinical trials suggests that healthy, postmenopausal women whose blood cholesterol levels are normal or lower are not at increased, short-term risk for heart attack when taking hormone therapy.

Flavanols in cocoa improve artery function, help relieve stress on heart

For people with diabetes, sipping a mug of steaming, flavorful cocoa may seem a guilty pleasure. But new research suggests that indulging a craving for cocoa can actually help blood vessels to function better and might soon be considered part of a healthy diet for the prevention of cardiovascular disease.

Bivalirudin improves net clinical outcomes and increases survival in heart attack patients

A study led by Gregg W. Stone, M.D., professor of medicine at Columbia University Medical Center/NewYork-Presbyterian and chairman of the Cardiovascular Research Foundation, has shown that heart attack patients who were administered the direct thrombin inhibitor bivalirudin during primary angioplasty had a reduced rate of adverse clinical events, a lower rate of major bleeding, and a lower mortality rate than those who were treated with a regimen of heparin and glycoprotein IIb/IIIa inhibitors (GPI).

Global burden of disease shifts from infectious diseases to noncommunicable diseases

The global burden of disease is shifting from infectious diseases to noncommunicable diseases, with chronic conditions such as heart disease and stroke now being the chief causes of death globally, according to a new WHO report published today. The shifting health trends indicate that leading infectious diseases - diarrhoea, HIV, tuberculosis, neonatal infections and malaria - will become less important causes of death globally over the next 20 years.

Making sense of the data in a controversial trial of a "clot-busting drug" for treating stroke

Minocycline may find new life as a stroke treatment

An old intravenous antibiotic may have new life as a stroke treatment, researchers say. Minocycline appears to reduce stroke damage in multiple ways - inhibiting white blood cells and enzymes that, at least acutely, can destroy brain tissue and blood vessels, respectively, says Dr. David Hess, chair of the Department of Neurology in the Medical College of Georgia School of Medicine.

Stroke plays a role in epilepsy development, especially for elderly

Seizures may be a sign of significant brain injury, and may occur in patients that experience any type of stroke. A new study finds that stroke patients with ensuing seizures are more likely to die in the 30 days following stroke than patients without seizures. The findings show a mortality rate of over 30 percent at thirty days after stroke.

Thiazide-type diuretic shown to be best first-choice drug for hypertensive patients

A study based at The University of Texas Health Science Center at Houston provides added justification that a thiazide-type diuretic is the best first-choice drug for hypertensive patients. The findings, published in the American Heart Association's Circulation, Volume 117, Issue 20, evaluate the results of a previous trial coordinated by researchers at The University of Texas School of Public Health, along with other recent studies.

Erection problems may signal serious heart disease

Erectile dysfunction is always a matter of the heart, but new research shows that more than romance is at stake. Two new studies of men with type 2 diabetes found that erectile dysfunction (ED) was a powerful early warning sign for serious heart disease, including heart attack and death.

Bypass not to blame for heart patients' mental decline

Heart patients often experience lasting problems with memory, language, and other cognitive skills after bypass surgery. However, these problems aren't caused by the surgery itself or the pump used to replace heart function during surgery, a new study by Johns Hopkins researchers suggests. The findings may lead to better approaches to prevent cognitive decline regardless of which treatment heart disease patients receive.
