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.

Genetic variations predispose Mexican Americans to insulin resistance

Although numerous studies have shown that low-grade inflammation is linked to heart disease and diabetes, more recent studies have shown that inflammation plays a role in insulin resistance, a syndrome that leads to diabetes and heart disease and affects about one in four adults in the United States.

Experimental drug therapy could open new window for treatment of deadly stroke

A new type of drug therapy that is currently being tested in Canada could significantly reduce the death rate caused by the deadliest form of stroke. According to the Canadian Heart and Stroke Foundation, new developments in stroke research make it more important than ever that Canadians recognize and react to the warning signs of stroke.

Doctors study surgery to stop epileptic seizures

Melinda Hillyard of Winchester, Va., first had epileptic seizures when she was eight years old. The seizures went away for years, then returned after the birth of her first child. "I never knew when my world would turn upside down," she recalled.

Patients with advanced heart failure significantly improved after receiving stem cell therapy

The study showed, 30 days after receiving the stem cells by injection into their hearts, patients improved an average of 41 percent in their hearts' pumping efficiency and the distance they could walk nonstop increased by 72 percent in a standard test widely used to assess heart patients.

Discovery will lead to more effective treatments for pulmonary arterial hypertension

A University of Alberta research team has discovered important new information they hope will lead to more effective treatments for pulmonary arterial hypertension (PAH)--a deadly form of high blood pressure in the pulmonary arteries caused by uncontrolled cell growth.

High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.

Genetic variation alters response to anti-clotting drug warfarin

Millions of people take the anticoagulant drug warfarin to prevent harmful clotting after a heart attack, stroke, or major surgery. But the proper dose of warfarin can vary greatly and can be hard to predict.

Hypertension, diabetes and obesity are important independent predictors of increased complications for patients undergoing major joint replacement surgery

Using a database of nearly 1 million Americans who underwent major joint replacement surgery, a team led by researchers at Duke University Medical Center have determined those surgical patients with diabetes, hypertension or obesity were significantly more likely to suffer post-operative complications.

Diabetics more sensitive to cardiovascular effects from air pollution

People with diabetes may be at higher risk for cardiovascular problems when air pollution levels are higher, according to a new study of Boston-area residents. The ability of the blood vessels to control blood flow was impaired in adults with diabetes on days with elevated levels of particles from traffic and coal-burning power plants.

We have been ingrained to think that seriously large people can only make improvements in their health if they diet and slim down

Behavior change and self-acceptance trump dieting hands-down when it comes to achieving long-term health improvements in obese women, according to a two-year study by nutrition researchers at the University of California, Davis.
