heart blockeage

A woman we know had a test showing her heart is blocked 50% on one side and 70% on the other. One dr said it was no problem, her local dr said he didn't want her doing anything physical while she was alone. How much blockage does there need to be before surgery is recommended. How much activity should someone with this much blockage do?
Thanks

The AHA/AAC guidelines are any arterial blockage less than 70% does not reguire treatment unless there is associated pain, shortness of breath, muscle fatique, etc.  

If there are symptoms, medication to dilate the coronary arteries, and if that doesn't resovle the symptoms, then an angioplasty and possibly a stent implant.  If the angioplasty shows there is blockage that is too long to stent, or the location prohibits, etc., then a operational by-pass would be the recommended procedure.

I have a totally blocked left arterial coronary, another (ICX) is 72% blocked, and I have no problems with medication for the past 5 years.  A stent can enlarge the vessel to 0.5mm, with medication I can see the enlargement of vessels, and meds to increase coronary arteries can in most situations dilate to at least 0.5mm.
