question: Hi doctor, My grandfather is 82 years old. He has diabetes as well as Alzheimer's. He had a heart attack before 15 days. Doctors are confused whether to go in for angioplasty or bypass considering his age and diabetic history. He had congestion in the lungs and had breathlessness and sleeplessness when admitted to the hospital. Herewith I have attached his laboratory reports. Please suggest a suitable procedure.
