Young people can’t get heart attacks
• While the risk of heart attack rises with age, teens and young adults can have heart attacks.
• Risk factors that are controlled early in life make it less likely to persist later in life
• The lesson is that just because someone is not “old” that does not mean that symptoms such as chest pain and shortness of breath are not signs of a heart attack.
