I live in Argentina. According to the law here every person undergoing surgery must get what is called a "surgical risk evaluation". This evaluation consists of an ECG and a set of questions asked by a cardiologist about your habits like if you do sports or stay mostly seated, about heart deceases of yourself or your family, about medication that you take, etc... The cardiologist writes then a report with the conclusions which can be high, medium or low surgical risk.
Honestly I don't understand why your surgeon is so picky if you are just going to get hair transplants with local anesthesia, it must be some compliance thing. If they insist they could tell you where to get the surgical risk evaluation in Buenos Aires the day before the surgery, it doesn't take more than 10 minutes and is not expensive
