CONCLUSIONS
! Coronary artery stenting is the treatment of choice for patients requiring coronary angioplasty
! Newer generation DES have almost negligible ISR
! Newer generation DES when combined with DAPT and optimal deployment a low risk of ST
! on-going studies to evaluate:
! newer stent platforms,
! anti-proliferative drugs,
! novel polymers,
! polymer-free stents
! and bioresorbable stents
! Probably there will not be one single stent suitable for all patients and lesions
! Stent according to:
! Genetic determinants,
! risk profile (for restenosis, thrombosis and bleeding) and
! lesion characteristics of individual patients.
