Abstract

Aims

To compare the outcomes of patients undergoing non-cardiac surgery (NCS) after PCI with either a drug-coated stent (DCS) or a bare-metal stent (BMS), followed by 1-month dual antiplatelet therapy and to explore the impact of the timing of NCS.

Methods

This is a subgroup analysis of the LEADERS FREE trial. The primary safety end point was a composite of cardiac death, myocardial infarction, or stent thrombosis, and the primary efficacy end point was clinically driven target lesion revascularization (TLR).

Results

Out of 2432 patients included in the LEADERS FREE trial, 278 (11.4%) underwent NCS within 1 year after PCI. Among NCS patients, the 1-year safety end point was numerically lower with DCS; however, this difference was not significant as compared to BMS (4.7% vs. 10.1%, HR: 0.459 [0.178–1.183], p = 0.099), clinically driven TLR was significantly lower after DCS (2.4% vs. 8.3%, HR: 0.281 [0.079—0.996], p = 0.036), and BARC 3–5 bleeding was similar with DCS vs. BMS (10.2% vs. 7.5%, p = 0.438). In patients treated with BMS, NCS within 3 months after PCI was associated with higher incidence of the safety end point than NCSs performed later: 14.9% vs. 4.4%, HR: 3.586 [1.012–12.709], p = 0.034. The timing of surgery had no impact on patients treated with DCS (4.7% vs. 4.7%, p = 0.947).

Conclusions

Among patients undergoing NCS after PCI, DCS-treated patients had a lower probability of clinically driven TLR compared with BMS. However, there was no significant difference in the occurrence of the primary composite safety end point or bleeding complications. Early NCS after BMS-PCI was associated with impaired safety, while the timing of NCS had no such influence after DCS implantation.
