He is recommended for Angiography.

Hello Sir/Mam, I don't know how to put it.. There was not any problem my father was facing regarding health.. We have gone for simple health check up and found the parameters for cholestrol and sugar is not appropriate and immediately dr has prescribed the medicines.. After ECHO and TMT tests, dr is suggesting to go for Angiography.. They have given the blood thinner too to take it for few days. Kindly help me to understand how is this process and it's after effects.. Situation is my father is currently alone by himself at hometown.. My mom and brother came to me as for my delivery.. We are not sure to make him travel to us right now will be good or not.. My father is saying it's a simple process, he will be able to manage with someone there with us as family.. 1. Should we make him travel to us and get the process done in Bangalore? 2. Is it ok to make him wait for 2 weeks and my family will return to him.. 3. Is it fine if he go for the procedure by himself as dr is suggesting?
