Can heart disease be detected by listening to the heart? - heart problems that can not be detected by ekg

I am 17 and I had pain in the chest on the left side for a while and recently went to an electrocardiogram. My doctor told me that the ECG is normal, if I am a pediatric cardiologist, who told me that the EKG was normal. He listened to my heart and said everything sounded good, but I do not know what cause pain in the chest on the left side.
My father died of a heart attack in 2005 at the age of 45 years and had a heart valve prolapse. The doctor said that heart disease [works] on your side of the family and said if I saw my father when I was 15 years have, which is better controlled, because that's where I took my father began to build . My father was not overweight, I'm not overweight, but problems behind the heart on both sides of my family. Juc ask if I echo ECG or if the cardiologist was able to say, listening and reading EKG?
Even if you do not have heart disease for many years now wait before a test?
