Preventing Stroke in Patients With Atrial Fibrillation

Article Abstract:

Aspirin is probably adequate to prevent stroke in most patients with atrial fibrillation but warfarin may be needed for those at high risk of stroke. Atrial fibrillation occurs when the upper part of the heart beats so rapidly it can throw off blood clots that travel to the brain and cause a stroke. Researchers reviewed several clinical trials comparing warfarin and aspirin with placebo in patients with atrial fibrillation. Both drugs can prevent blood clots. Aspirin was sufficient in people under 65 who had no other risk factors for stroke. However, warfarin was more effective in older patients who had other risk factors.

Rising stroke rates spur efforts to identify risks, prevent disease

Article Abstract:

Public education is needed to teach people the risks and warning signs of stroke. Stroke is caused by a blood clot that blocks the flow of blood to an area of the brain. The same condition in the heart is called a heart attack. Stroke is a medical emergency and can be treated with drugs that break up the clot. However, patients and their families must know the warning signs so they can reach the hospital quickly. The National Stroke Association has developed guidelines for the public, which will be urgently needed as baby boomers reach the age of greatest risk.

Individualizing Aspirin Therapy for Prevention of Cardiovascular Events

Article Abstract:

Physicians can use individual patient characteristics to determine which patients with cardiovascular disease should receive aspirin to prevent heart attack or stroke. Aspirin can substantially reduce the risk of heart attack and strokes caused by blood clots. However, because it prevents blood clotting, it increases the risk of hemorrhagic strokes. The benefits of aspirin will outweigh the risk of hemorrhagic stroke in patients with a high risk of heart attack. This may not be true in patients at low risk of a heart attack.
