Stroke PreventionThe good news is that 80 percent of all strokes are preventable. It startswith managing keyrisk factors, including high blood pressure, cigarette smoking, atrial fibrillation and physical inactivity. More than half of all strokes are caused by uncontrolled hypertension or high blood pressure, making it the most important risk factor to control.

Medical treatments may be used to control high blood pressure and/or manage atrial fibrillation among high-risk patients. Those medicines include: Anticoagulants/AntiplateletsAntiplatelet agents such as aspirin and anticoagulants, such as warfarin, interfere with the blood's ability to clot and can play an important role in preventing stroke.Read more about anticoagulants. AntihypertensivesAntihypertensives are medications that treat high blood pressure. Depending on the type of medication, they can lower blood pressure by opening the blood vessels, decreasing blood volume or decreasing the rate and/or force of heart contraction.Learn about the types of antihypertensives.Additionally, when arteries show plaque buildup or blockage, medical procedures may be needed. Such as: Carotid EndarterectomyCarotid endarterectomy, also called carotid artery surgery, is a procedure in which blood vessel blockage (fatty plaque) is surgically removed from the carotid artery.View a detailed illustration of carotid endarterectomy (opens in new window). Angioplasty/StentsDoctors sometimes use balloon angioplasty and implantable steel screens called stents to treat cardiovascular disease and help open up the blocked blood vessel.

When a Stroke Occurs: Quick Stroke Treatment Can Save LivesIf youre having a stroke, its critical that youget medical attention right away. Immediate treatment may minimize the long-term effects of a stroke and prevent death.There are two types of strokes: hemorrhagic or ischemic. Anischemic strokeoccurs as a result of an obstruction within a blood vessel supplying blood to the brain. It accounts for 87 percent of all stroke cases. Ahemorrhagic strokeoccurs when a weakened blood vessel ruptures and spills blood into brain tissue. The most common cause for the rupture is uncontrolled hypertension (high blood pressure). There are two other types of weakened blood vessels that also cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs). Treatment differs depending on the type of stroke.Ischemic Stroke TreatmenttPA, the Gold Standard

The only FDA approved treatment for ischemic strokes is tissue plasminogen activator (tPA, also known as IV rtPA, given through an IV in the arm). tPA works by dissolving the clot and improving blood flow to the part of the brain being deprived of blood flow. If administered within 3 hours(and up to 4.5 hours in certain eligible patients), tPA may improve the chances of recovering from a stroke. A significant number of stroke victims dont get to the hospital in time for tPA treatment; this is why its so important to identify a stroke immediately.
