Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The reduction of thrombus burden and thrombus volume, measured as the difference of Thrombotic Score between baseline and control at OCT. The control angiography and OCT will be performed between day 5 th and 7 th . The primary coagulation-related of the study is the factor XIa activity at baseline and after 4-7 days of treatments;Secondary Objective: Coagulation cascade factors activity at presentation and after 4-7 days Factor Xa and IIa (common pathway) Factor XIa and VIIIa (intrinsic pathway) Factor VIIa (extrinsic pathway) Angiographic outcomes before stenting implantation: White vs. red thrombus presence Angiographic outcomes after stenting implantation: Final TIMI flow; Final TIMI frame count; Final myocardial blush grade; Clinical outcomes at 30 days: - The percentage of patients with MACE (composite of all cause death, myocardial infarction, stroke or new target vessel revascularization) - The percentage of patients with major bleeding - The percentage of patients with any bleeding Safety outcome at 30 days: the rate of major bleedings at 30-day;Primary end point(s): The reduction of thrombus burden and thrombus volume, measured as the difference of Thrombotic Score between baseline and control at OCT. The control angiography and OCT will be performed between day 5 th and 7 th . The primary coagulation-related of the study is the factor XIa activity at baseline and after 4-7 days of treatments;Timepoint(s) of evaluation of this end point: 4-7 days | — |
