Should we go for bypass surgery or is there any other solution?

My mother is 54years old.Her angiography reports is as follows:
LMCA : shows 40% stenosis distally.
LAD : Shows 80% discrete stenosis at its ostium, followed by 75% tubular stenosis in the proximal segment. Rest of the LAD is free of disease.
LCx: Shows plaque at its ostium and 60% long segment stenosis in the mid LCx OM1 is a large vessel with 70% stenosis in the mid segment.
RCA: Is a dominant artery and shows 50% stenosis distally and extending into the PD.PD branch shows 80% ostial stenosis.
LIMA/RIMA : Normal
LV Angio : Not done
Conclusion : Triple Vessel Disease.

Thanks doctor. we have got her 2D Echo\Color Doppler test done. Her report is as follows:
LV:- Normal left venticular size.

No LV regional waal motion abnormality seen at rest.
Mild LV diastolic dysfucntion.Noraml LVEDP.
Normal left ventricualr systolic function.
Overall LVEF 60%.

2) Normal sized LA,RA and RV with normal RV contarctility.

3) Mild TR.Mild PAH.PASP=33 mm Hg
   Other cardiac valves are normal
4)No clot/vegetation
5) No pericardial effusion.
6) Intact sepate

Can you please explain how to interpret this report and is there no means that she could do only with medication and diet control?
