My father Mr jayanta Banerjee had been suffering from chest pain for the last one month. we consulted a cardiologist in kolkata who told us to do an angiograph to see the blockage amount. in the graph it was detected that my father is having a 100percent blockage in the middle RCA. but he did nt have any heart attacks.so we were told to do an early PTCA stenting RCA..It happened on 28th April 2011. but it was a failure and the reason was given that my father s blockage has become too hard to operate angioplasty.Now he is in medicine and doctors told that he will not be having any pains and heart attacks anymore. but suddenly the pain has started from yesterday ie 3rd may and sumtimes its paining in the leftside ribs and sumtimes in d middle upper abdomen and middle chest.in this situation can we take the patient to your s or what do u suggest us to do?if u suggest us to take what precautions should we take while taking d patient 4m kolkata?name of the patient is Mr Jayanta Banerjee, age is 47 height is 5 7 and weight is 69. regarding medical history ie, B.P sugar everything is under control except he is having spondelitis which was treated in your hospital in 2003....
