A stroke and a heart attack are two separate conditions, but they both occur when blood flow to the heart is blocked. A stroke occurs when a blood clot blocks an artery carrying oxygen-rich blood to the brain, while a heart attack occurs when an artery supplying oxygen-rich blood to the heart is blocked.
The symptoms of a stroke can vary, but usually include sudden numbness or weakness in the face, arm, or leg, confusion or difficulty speaking, difficulty seeing, and difficulty walking. On the other hand, the symptoms of a heart attack are chest pain, nausea, sweating, and shortness of breath. A heart attack is usually more sudden and more severe than a stroke.
