Dear Doctors, My mother in law got heart attack a day ago, she is under observation, admitted in hospital and being monitored by doctors. ECG has been done but angiography and Echo has not been done yet. Is it compulsory to do angiography if it is, then why doctors are doing late for angiography? After attack Within how much time angiography should be done? Patient is stable for now she is able to speak but has little pain in back. I asked doctor for angiography but then he started shouting on me saying don't cross your limit, you know everything, you only do it and all. Please help me to understand what is going on and what we should do. Is there any risk if there is delay in angiography? Should we move the patient to any other? hospital? Thanks a lot.
