My gran was born with an enlarged heart and so was my dad.  My dad was recently taken to hospital with heart failure and pnuemonia but my gran suffered no heart problems and died 3 years ago of bladder cancer.  It is likey that I have an enlarged heart also?  Im worried!
Enlarged heart may be hereditary ...in fact some diseases of heart are hereditary...if you have symptoms please go for ECG and echocardiography...all your doubts will be cleared
