My teen daughter is being referred to a pediatric cardiologist for chest pain and dizziness during exercise. why's this ?. we also have family history of been high blood pressure and cholesterol?

Family history is always a sign of possible complications and must be addressed. Knowing this can help control those factors that lead to these problems. A controlled diet and proper exercises and mental fitness will all help in keeping these symptoms under control and normal. Seeing a cardiologist is a pathway for treatment and a healthy and normal life.
