My father is 75 years old. He had a chest pain a week back and went to a normal clinic, where they took an ECG and said there is a slight variation in the ecg report, and asked him to go to a cardiologist with the report. But my dad went to his cardiologist only after 4 days. They took an echo test and said he has had an attack, the troponin T was 4.67. then an angiogram said there is a block. but the consulting doctor said that administering medicine is enough becuase he has not been taking medicines. He also said there is no need of angioplasty. Please comment on the doctors remarks please.
