Inclusion criteria

Inclusion criteria: (1) Aged >20 years, (2) a diagnosis of ACS, (3) native coronary artery lesions, (4) optical coherence tomography with sufficient quality before PCI, (5) successful thrombus aspiration with enough amount of thrombus. Recent guidelines and consensus documents indicated that routine thrombus aspiration is not recommended, but in cases of large residual thrombus burden, thrombus aspiration may be considered. Therefore, we performed athero-thrombotic aspiration only in patients who would have a merit of the aspiration procedure due to large thrombus burden.

Exclusion criteria

Exclusion criteria: (1) they have cardiogenic shock, (2) they have coronary bypass grafting (CABG), (3) they have contraindications to anticoagulation and anti-platelet therapy, (4) lesions located in tortuous vessels, in ostial segment, and in the left main stem are excluded from the study due to the difficulty in performing high-quality intracoronary imaging.

Design outcomes

The primary endpoint is a composite of cardiovascular death, acute coronary syndrome (ACS), ischemia-driven revascularization, cardiogenic shock, and cardiac failure required hospital admission for 3 years.

Secondary

MeasureTime frame
Secondary endpoints are the individual components of the primary endpoints.
