Coronary Artery Triple Vessel Disease.

My father was unable to urinate so it was reported that there was kidney stone. So surgery pack was conducted & in ECHO test on 19.01.2018 it was reported that Left Atrium was 45mm(12-22mm Normal Range(NR)) & LVID(ed) =60.1mm(19-32 mmNR) & LVID(es) = 45mm(16-19mm). Thus, LV dysfunction & CAD(RWMA) was the final diagnosis. Cardiologist further referred Angiography for final outcome. But my brain surgery was conducted on 29.01.2018 so he was preparing for my surgery fees. On 8th Feb, he has done Angiography test & the route used is Right Radial Artery 5F sheath and hardware used is 5F TIG catheter & contrast used visipaque. The findings of the report is- LMCA & LIMA are Normal, LAD & RCA are 100% occluded LCX is 60-70% occluded. Cardiologist recommended immediate by surgery & angiography operation is impossible due to age. But my father is really afraid of by pass surgery. So he found non-invasive procedure by Dr. Bimal Chajer & was a visitor & doing on EECP machine. What shall I do?
