Each year, nearly 800,000 people have their first heart attack and an additional 470,000 have another heart attack. The most common signal of a heart attack is persistent chest pain, discomfort or pressure that lasts longer than 3–5 minutes. Other signals include pain, discomfort or pressure felt in or spreading to the other parts of the body, such as the shoulder, arm or jaw; trouble breathing; pale or ashen skin; heavy sweating; dizziness; nausea or vomiting. The quicker you recognize a cardiac emergency and take action, the better the chance of survival. Your response can help save a life.
