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.

Aspirin can significantly reduce the risk of stroke in women

A meta-analysis of more than 95,000 patients has shown that aspirin can significantly reduce the risk of stroke in women, but it appears to have no protective effect in men, according to a new analysis by Duke University Medical Center cardiologists.

Re-opening of carotid arteries in stroke has high success rate with stenting

University of Pittsburgh researchers report a high level of effectiveness in re-opening completely blocked internal carotid arteries (ICA) as late as two to three days after acute stroke symptoms by using stents.

Tamoxifen reduces the risk of invasive and noninvasive breast cancer

Data from additional years of follow-up of a large randomized placebo-controlled clinical trial of tamoxifen for the prevention of breast cancer confirm that the drug reduces the risk of invasive and noninvasive breast cancer, according to a report that appears in the current issue of the Journal of the National Cancer Institute.

Aspirin advice ignored by those who need it

A daily dose of aspirin is an inexpensive, proven strategy for reducing the likelihood of heart disease among those most at risk for such disorders, yet a new study from the Stanford University School of Medicine shows that aspirin therapy is being used by fewer than one-third of the U.S. outpatients who would benefit from it.

Carvedilol may improve heart failure and help prevent sudden death

Research shows that Carvedilol, a cardiovascular drug, could be useful in reducing cardiac death in high risk patients with prior myocardial infarction and/or heart failure and also in reducing the incidence and/or preventing the occurrence of atrial fibrillation in a number of clinical situations.

Tamoxifen reduces long-term risk of cancer

According to a new study released this week, women at high risk for breast cancer who take the well-known drug Tamoxifen, can reduce their long-term risk of developing the disease.

Lack of aggressive treatment for clogged leg blood vessels means missed heart attack prevention opportunity

Despite the fact that clogged arteries in the legs usually mean clogged arteries near the heart, doctors often fail to give heart-protecting drugs to people with severe leg blood vessel blockages, a new University of Michigan-led study finds.

Women warned about contraceptive patch

The makers of a revolutionary contraceptive patch are warning women that they are at a greater risk of blood clots and other serious side-effects because of the higher doses of hormones the patch delivers.

Blood pressure near the heart is more predictive of cardiovascular outcomes than blood pressure measured in the arm

Results from a new study show that amlodipine-based (calcium channel blocker) treatment is much more effective at reducing blood pressure near the heart than a conventional atenolol-based (beta blocker) regimen.

Seeing under the skin to reveal early signs of heart disease and stroke

A revolutionary diagnostic technique that sees under the skin sounds rooted in the realms of science fiction. But an invention akin to the Star Trek small handheld body scanner that shines light into the skin to detect early signs of heart disease and stroke could be on the market in less than two years.

Norvasc better than beta blockers for lowering blood pressure

According to a study presented at a meeting of the American Heart Association, Norvasc, was more effective at reducing blood pressure near the heart than standard, older treatments such as beta blockers.

Fundamental flaws in many medical studies must be fixed in order to catch signs of harm

Only by analyzing results using a statistical method that considers several factors at once -- for instance, overall heart attack risk, rather than just individual risk factors such as age -- will researchers truly be able to see how the risks and benefits of a treatment vary from patient to patient, the study suggests.

Habitual coffee drinking is not associated with an increased risk of hypertension in women

Habitual coffee drinking is not associated with an increased risk of hypertension in women, although an association was found with the consumption of sugared or diet colas, according to a study in the November 9 issue of JAMA: The Journal of the American Medical Association.

Cellular signal may determine life or death for damaged brain cells

Scientists at the Universities of Heidelberg and Ulm and a unit of the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have discovered that a specific signal within brain cells may determine whether they live or die after a stroke.

Obstructive sleep apnea significantly increases the risk of stroke

An observational study of more than 1,000 patients at the Yale Center for Sleep Medicine found that obstructive sleep apnea significantly increases the risk of stroke or death from any cause, and that the risk is linked to sleep apnea severity.

Statins reduce the risk of stroke after carotid artery endarterectomy

Carotid artery endarterectomy (CEA) is the most commonly performed operation to prevent stroke in the United States. However, the operation itself carries a small risk of stroke.

Human umbilical cord blood cells may widen treatment window for stroke

An experimental treatment that spares disability from acute stroke may be delivered much later than the current three-hour treatment standard – a potential advance needed to benefit more stroke victims.

Hopkins study finds no "cognitive decline" after use of heart-lung machine during bypass surgery

The use of a cardiopulmonary heart pump during coronary artery bypass grafting (CABG) surgery does not significantly damage such high-level mental tasks as thinking, reasoning and remembering, according to a study by Johns Hopkins researchers recently published in Neurology.

Sleep apnea sufferers have double the risk of stroke and death

Apparently as many as 4 percent of Americans suffer from extreme daytime fatigue because their sleep apnea forces them to repeatedly wake up if only for a second.

Relax girls - it's not the coffee that's raising your blood pressure!

According to the latest study, having a coffee drinking habit is not going to increase your blood pressure if you are a woman, but knocking back the colas is a different kettle of fish!
