Stenosis in stents

[Tinu1959]

Can anyone tell what leads to stenosis in the stent and how it can be avoided?? In my case LAD was 100% blocked at the time of MI and stent was implanted to open it. The other artery LCx is 100% blocked but is getting filled retrogradely via LAD(after opening) and RCA(which is clear). My Cardiologist has informed me today that I need to be careful about stenosis of my LAD stent. A repeat Angio in January 2008 did not show any stenosis. MI was in august 2008. I take beta blockers, ACE-I, platellate and thinning drugs. I am on low fat/salt diet. My cholostrol is within the limits. How to avoid this situation??

Thanks in advance.

Thankyou so much. In my case LAD was implanted with bare metal patented stent. Having that in place, what measures I need to take so as to avoid restenosis(sorry for spelling it as stenosis). Eight months have passed now. Is restenosis still a possibility???

Having LCx blocked and LAD(stented), if gets restenosis, what I understand there are chances heart may be able to feed itself through collaterals relying totally on RCA(which is open), provided collaterals develop by this time???

Is this correct. Thanks for your valuable time.
