Talk to Cardiologist on Veins Blockage Shown In Recent Angiography

My brother in law had high bp issue since almost 5 years. Recently he was not feeling well and upon examination was told that he had a minor heart attack. His angiography has been done and i am attaching the report here. Doctors panel will sit in a few hours to discuss his case but we as a family are v concerned about him therefore in the mean time i want to have comments from doctors here. Please let us know what does the report say and what could be the possible treatment for him?
