Key result
Incomplete stent apposition was associated with a higher rate of myocardial infarction and very late stent thrombosis during long-term follow-up after DES implantation.
Why the study?
Does the presence of incomplete stent apposition (ISA) 8 months after DES implantation increase the risk of myocardial infarction and very late stent thrombosis?
Does the presence of incomplete stent apposition (ISA) 8 months after DES implantation increase the risk of myocardial infarction and very late stent thrombosis?
Incomplete stent apposition detected by IVUS 8 months post-DES implantation is a prognostic marker for increased long-term risk of myocardial infarction and very late stent thrombosis.
ISA on IVUS at 8 months may flag higher long-term MI and VLST risk after DES; leaves open whether apposition optimization improves outcomes.
In the present study, the presence of ISA as assessed by IVUS 8 months after DES implantation was associated with a higher rate of myocardial infarction and very late stent thrombosis during long-term follow-up. The prognostic impact of ISA on long-term clinical outcomes requires further investigation.
