Hi,
Thanks for your question.
As you have mentioned you have undergone
PTCA with 3 stents and non diabetic and non Hypertensive, I would like to advise you -
1) Avoid fatty, oily foods.
2) Take adequate protein intake in the form of pulses, soy bean, skimmed milk.
3) Take green leafy vegetables, salads, fruits daily in adequate quantity.
4) Decrease salt intake.
Along with this follow regular exercise after discussing with your doctor.
Be compliant with your medicines, do not stop any medicine advised without consulting your doctor.
Hope this helps you, if so do vote as helpful.
