Cohort study
Impact of Eruptive vs Noneruptive Calcified Nodule Morphology on Acute and Long-Term Outcomes After Stenting
- Observational cohort study
Authors' conclusion
Compared with noneruptive CN morphology, lesions with an eruptive CN appearance on optical coherence tomography had a worse poststent long-term clinical outcome despite better acute stent expansion.
Study context
- Population
- Patients with target lesion calcified nodules on pre- and postintervention OCT undergoing stenting236 with calcified nodule (CNs)
- Participants
- 3,231 patients
- Exposure
- Eruptive CN vs noneruptive CN
- Eruptive CNn = 126
- Noneruptive CNn = 104reference
- Outcome
- Target lesion failure (TLF) (cardiac death, target vessel MI or clinically driven target lesion revascularization)
- Follow-up
- 2 years
