Heart Attacks and Strokes
A blockage in the heart's arteries may reduce or completely cut off the blood supply to a portion of the heart. This can cause a blood clot to form and stop blood flow in a coronary artery, resulting in a heart attack. Some heart attacks come suddenly, but most start slowly with mild pain or discomfort in the chest, neck or shoulders.
Stroke, on the other hand, occurs suddenly and is the leading cause of disability in the United States. Symptoms include dizziness, difficulty understanding speech, confusion or headache. It can cause weakness or numbness in any part of the body. If not treated promptly, it can result in seizures, cerebral swelling, hemorrhaging or paralysis.
