My father is 63 years old. He had an angioplasty before four years. From the last few days, he complained about shortness of breath. I took him to a cardiologist and the doctor just took the BP and suggested to admit my father. He said that previous angioplasty is of no use and he will do angiography again and if required angioplasty. To take a second opinion, I visited another cardiologist. He asked us to do x-ray, ECG and echo. As per his suggestion there is no need of another operation and the present condition will be treated with medicines only. Now I am really confused. Please guide me if there is a need of any other operation. I have attached the copies of latest prescription, ECG, echo and copy of documents of angioplasty done before. Thanks in advance.
