I m 17 and I ve had chest pains on my left side for a while now and recently went for an EKG . My doctor told me the EKG was abnormal so she referred me to a pediatric cardiologist that told me the EKG was normal. He listened to my heart and said everything sounded good but he didn t know what would be causing the chest pains on the left side. My dad passed away from a massive heart attack in 2005 at the age of 45 and had a prolapse heart valve. The doctor said he had heart disease [it runs on his side of the family] and said that if he saw my dad when he was 15, that it could have been better controlled because that was when he assumed my dad started to have it build up. My dad was not overweight , I am not overweight but heart problems run on both sides of my family. Just wondering if I need an echo cardiogram or if the cardiologist was able to tell by listening and by reading the EKG? also, if I have no heart disease now how many years should I wait before going to get a test done?
