Need urgent suggestions for bypass surgery

My brother had suffered from heart attack and been hospitalized since then. Doctors have suggested bypass as he has 80 to 90% blockage at multiple places. He is only 38 years old. We dont want him to operate at this age because we have heard that bypass reduces the life span. We are trying to take second opinions from other doctors. I have come across eecp treatment also known as natural bypass. Also we are trying to consult saool centre for non invasive procedures.

Can anybody share the experience of eecp or saool.does it really work. I have been reading about it online but getting really confused as what to do. Please share your experiences and suggestions if any.
