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.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

'Bad' metabolism cloggs up arteries

Scientists are now saying that a 'bad' metabolism may explain why some people who have never smoked and do not have high cholesterol levels suffer from a potentially lethal build-up of plaque in the arteries.

Most serious side effects in statins may be higher in one of the newest drugs, rosuvastatin (Crestor)

A post-market analysis of cholesterol-lowering drugs called statins indicates that some of the most serious side effects may be higher in one of the newest drugs, rosuvastatin (Crestor). The drug is the strongest statin available because it has the greatest effect per milligram on low-density lipoprotein ("bad" cholesterol).

A diet rich in milk does not increase the risk of heart disease and stroke

The research team asked a representative sample of 764 men to weigh and record every item of food and drink they consumed for seven consecutive days. Just under 90% of the sample (665) produced complete and detailed diaries.

Patients at high risk of stroke may need to continue Warfarin therapy after heart rhythm is controlled

Treatment with warfarin, a medication that prevents blood clotting, may reduce the risk of stroke by more than two-thirds in patients with atrial fibrillation (AF), a condition which places them at high risk of stroke, according to a study in the May 23 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Cystatin-C, a new blood test for kidney function, is a better predictor of death and cardiovascular risk among the elderly

Investigators for NHLBI's Cardiovascular Health Study compared the two measures of kidney function, cystatin-C and the standard test creatinine, as predictors of death from all causes, death from cardiovascular causes, and incidence of heart attack and stroke among 4,637 elderly participants in the study.

Two out of three Americans with type-2 diabetes do not have their disease under control

According to a new survey two out of three Americans with type-2 diabetes do not have their disease under control and are putting themselves at risk of early deaths from stroke, heart attack or kidney failure as well as blindness and limb loss.

Hypertension drug combination yields high rate of blood pressure control in hard-to-treat patients

The study, conducted at the University of Maryland School of Medicine and 118 other sites, was focused on bringing down systolic blood pressure, the top number in a blood pressure reading, which is the more difficult number to bring down.

A drug that controls blood pressure and reduces heart risk also appears to protect against diabetes

In new results from the VALUE trial that pitted the drug valsartan against another blood pressure drug, amlodipine, the patients taking valsartan were found to have a 23 percent lower risk of developing diabetes during the four or more years of the study.
