Sad to hear, may Allah grant him Jannat...ameen
Our doctors failed to diagnose heart conditions in children and young people which led to early heart attacks and you know young heart attacks are quite fatal as compared to older ones....
My cousin went to many doctors as far as I can remember, he often complain irregular heart beat and at one occasion near 5 years back he visit me and complain same condition so I took him to a doctor (heart specialist) who casually checked him and advised some vitamins and other medication and declared it may be due to vitamin deficiency and when I put pressure he done ECG and declared him fit and now just after one year marriage he is dead......not only he died but is the death of her newly wed wife..... you are woman you may understand her feelings...a person who bought a separate house worth 70 lakhs and new car for his bride died just after 10 or 11 months of marriage just because since his childhood many doctors fails to diagnose his heart condition.
I have no faith left on desi doctors...seriously.
