NCT05331547

Brief Summary

The purpose of the study is to assess the safety and efficacy of the BioFreedom Ultra stent for treatment of STEMI patients. Besides, in patients who are clinically indicated for a stage procedure, Investigators aim to assess the angiographic and endovascular healing of BioFreedom Ultra stent at one month This is a prospective, single center, post marketing registry. Investigators aim to recruit 50 patients. All enrolled patients will be followed up for 12 months. Restudy Subgroup For subjects who are clinically indicated for staged procedure, they will be recruited into restudy subgroup. Restudy angiogram of target lesion will be performed at 28 (±7) days. Intravascular OCT will be performed. The primary endpoint is target lesion failure (TLF) defined as composite of cardiovascular death, target-vessel related myocardial infarction (Q-wave and non-Q-wave), or ischemia-driven target lesion revascularization within 12 months (device-oriented outcome per ARC definitions) The co-primary endpoint in subjects who require stage procedure is stent strut coverage (degree of endothelialisation) as assessed by optic coherence tomography (OCT) at one month Secondary endpoints include

  1. 1.All-cause mortality
  2. 2.Cardiovascular death (cardiovascular and undetermined)
  3. 3.The composite of cardiovascular death, Target Lesion (TL)-related myocardial infarction and TL-related definite or probable stent thrombosis at one year.
  4. 4.Stroke disabling and non-disabling ARC definition
  5. 5.Myocardial infarction
  6. 6.ARC Stent thrombosis
  7. 7.Clinically driven TLR at any follow-up time point
  8. 8.Clinically driven target vessel revascularization
  9. 9.Any revascularization within 12 months following the index procedure, unless they are planned within the 1st month
  10. 10.Bleeding per BARC criteria
  11. 11.Restudy angiographic result (QCA)
  12. 12.OCT parameters including neointimal volume, neointimal area etc

Study Population

A prospective, single center, post marketing registry. We aim to recruit 50 patients. All enrolled patients will be followed up for 12 months.

You may qualify if:

  • STEMI patients treated with one or several BioFreedom stent(s)
  • Patients who agree to comply with the follow up requirements.
  • Patients with a life expectancy of \> 1 year at time of consent.
  • Patients eligible to receive dual anti platelet therapy (DAPT). The establishment of the DAPT regimen is at the physician's discretion.

You may not qualify if:

  • Patients in cardiogenic shock
  • Any out of hospital cardiac arrest
  • Glasgow score \< 15
  • Patients unable or unwilling to give documented informed consent
  • Patients taking part in another interventional trial which has not completed follow-up for the primary endpoint
  • Pregnant or breastfeeding women
