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.

Common SNP in sequence of human genome conferring risk of vascular diseases discovered

Scientists at deCODE genetics and academic colleagues from the Netherlands and twelve other countries across Europe and North America today report the discovery of a common single-letter variation (SNP) in the sequence of the human genome conferring risk of a range of vascular diseases. The SNP confers risk of abdominal aortic aneurysm (AAA), early-onset heart attack, peripheral artery disease (PAD), and pulmonary embolism, independent of other known risk factors.
