Abstract | PURPOSE: METHODS: This trial used a retrospective cohort study design. Medical information from 736 patients with CTO who underwent PCI with bivalirudin or UFH at the First Affiliated Hospital of Zhengzhou University from July 2019 to September 2020 was extracted and analyzed. The primary end point was the 30-day incidence of net adverse clinical events (NACEs), and the secondary end point was the major adverse cardiovascular events (MACEs), which were related to safety and efficacy, respectively. Other end points incorporated each component of the primary outcome, target vessel revascularization, and stent thrombosis. Clinical and procedural characteristics at baseline were adjusted by using a logistic regression model. FINDINGS: Overall, 71.5% of patients with CTO used the radial approach. Both groups exhibited nonsignificant differences in the majority of baseline characteristics. The bivalirudin group was associated with a significant reduction in NACEs (12.9% vs 21.5%; P = 0.002) and major bleeding (2.5% vs 8.0%; P = 0.001) versus the UFH group at the end of the 30-day follow-up. The incidence of MACEs, myocardial infarction, death, stroke, stent thrombosis, and target vessel revascularization did not differ significantly between the 2 groups. Moreover, the bivalirudin group also reported a lower incidence of NACEs in the prespecified subgroups. IMPLICATIONS:
Bivalirudin exhibited comparative efficacy but superior safety compared with UFH among patients with CTO undergoing PCI. Chinese Clinical Trial Registry: ChiCTR2000034771.
