Hi doctor! My 82-year-old mother has diabetes, high blood pressure and heart valve regurgitation 2/4 10 years, in January 2020 she had a left brain blockage and now she fell, the doctor checked her and said she had an obstructive stroke. right brain, heart vascular occlusion, renal failure. So the doctor asked me, should my mother have a stroke on the right brain and heart vessels and kidney failure, should a coronary artery stent be placed? Looking forward to the doctor's advice, thank you!
