Hello There, I Have A Family History Of Heart Problems-

Hello there, I have a family history of heart problems- my dad and my 3 brothers all died of heart attacks, ranging in the ages of 42-60. I am now 44 y/o. I have high blood pressure and are currently on medication- crestor, karvizide and cartia. Since yesterday- I have an intermittent dull ache on my chest area and it comes and goes. I am not experiencing the classis symptoms such as sweating, shortness of breath, pain in the arm or neck other parts of my body- just this dull ache. I have had this before and I got checked by my GP straightaway and it was a false alarm. Should I be worried due to this dull ache? Please advise. Thanks, Daniel
