Bypass or Medication

Hi,
My father is aged 80 years and had recently done Angiogram. The report says that:
LAD- Type III vessel, proximal LAD shows 70% stenosis, mid LAD shows tandem 90% stenosis, Daignols- normal
LCA- Normal
RCA-Dominant, totally occluded in the middle, distal RCA fills retrogradely from left side, PSA/PLV- fill by collaterals from left side

He does not have any chest pain, he lives a healthy lifestyle with low cholestrol diet, he has alo now quit smoking

Should we go for CABG or only medication can help?

The 90% blockage in the middle of the left artery descending would be a cause for concern to any Cardiologist. Have they followed up with any scans, such as a nuclear scan, to determine if tissue is being affected? Not everyone feels symptoms with a lack of oxygen, some people even have heart attacks with no discomfort and so I wouldn't rely too much on how he feels. The 70% blockage is on the borderline and could continue to be treated with medication if necessary, but I would look into the 90%, this is a high percentage. You could inquire as to whether they could stent the blockage.
