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.

Lowering of LDL level shows limited benefit for patients with previous heart attack

Patients who have had a heart attack and are treated with a high dose of a statin drug did not have significant reduction in the primary outcome of major cardiac events (coronary death, nonfatal acute heart attack, or cardiac arrest with resuscitation), but did appear to have reduced risk when certain secondary outcomes (composite end points of any coronary heart disease event) were examined, according to a study in the November 16 issue of JAMA.
