Both heart disease and stroke are known as cardiovascular diseases, which are disorders of the heart and blood vessel system. Coronary heart disease is a disease of the blood vessels of the heart, known as "coronary arteries." Coronary heart disease causes chest pain (angina) and heart attacks. Blood brings oxygen and nutrients to the heart. When too little blood flows to the heart, angina results.

When the blood flow is critically reduced, a heart attack occurs. A lack of blood flow to the brain or, in some cases, bleeding in the brain causes a stroke. Some other cardiovascular diseases are high blood pressure and rheumatic heart disease.

Preventing Stroke
YOU CAN REDUCE YOUR RISK OF STROKE!

Common heart disorders such as coronary artery disease, valve defects, irregular heart beat, and enlargement of one of the heart's chambers can result in blood clots that may break loose and block vessels in or leading to the brain causing a stroke.

The most common blood vessel disease, caused by the buildup of fatty deposits in the arteries, is called atherosclerosis. Your doctor will treat your heart disease and may also prescribe medication, such as aspirin, to help prevent the formation of clots. Your doctor may recommend surgery to clean out a clogged neck artery if you match a particular risk profile.

If you are over 50, National Institute of Neurological Disorders and Stroke scientists believe you and your doctor should make a decision about aspirin therapy. A doctor can evaluate your risk factors and help you decide if you will benefit from aspirin or other blood-thinning therapy.
