hi mam,i can understand your apprehension.it is clear that there is no stenosis of carotids which would have been a serious issue.only a small
cholesterol plaque is significant as it is in both the arteries and also he had previous asymptomatic or unnoticed episodes of stroke.so, i suggest you to please concentrate on a few aspects,risk factor modification i.e;
1.please quit smoking if you are habituated to.
2.if you are a hypertensive,it must be controlled well.
3.please take a balanced diet which has very low cholesterol,low
carbohydrates,moderate proteins,high fibre.
4.regularly take
aspirin as prescribed by your GP.
5.please be vigilant about your blood glucose levels if you are a
diabetic.
anyway you need not restrict too much but just be alert to report any kind of symptoms like
dizziness,
severe headache,weakness of limbs,
loss of consciousness.take care.bye.
