BACKGROUNDS

Data on optimal antiplatelet therapy in patients undergoing stenting of the proximal left anterior descending artery (LAD) are limited.

METHODS

This is a post-hoc analysis of the GLOBAL LEADERS trial, a prospective, multi-center, randomized controlled trial, comparing the experimental strategy (1-month dual anti-platelet therapy [DAPT] followed by 23-month ticagrelor monotherapy) with the reference regimen (12-month DAPT followed by 12-month aspirin monotherapy) in relation to stenting of the proximal LAD. The primary endpoint was the composite of all-cause death or new Q-wave myocardial infarction (MI) and key secondary safety endpoint was Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding at two years.

RESULTS

Among 15,845 patients included in the analysis, 3823 (23.9%) patients underwent stenting of the proximal LAD, while 12,022 (75.2%) did not. In the proximal LAD stenting group, there was no significant difference in the risk of the primary endpoint between the two antiplatelet strategies (3.38% vs. 3.93%; hazard ratio [HR]:0.86; 95% CI:0.62-1.20; Pinteraction = 0.951). However, the risk of any MI (2.63% vs. 3.88%; HR:0.68; 95% CI:0.47-0.97; Pinteraction = 0.015) and any revascularization (7.84% vs. 9.94%; HR:0.78; 95% CI:0.63-0.97; Pinteraction = 0.058) was significantly lower in the experimental strategy group, while demonstrating a similar risk of BARC type 3 or 5 bleeding between the two antiplatelet strategies (1.93% vs. 1.99%; HR:0.98; 95% CI:0.62-1.54; Pinteraction = 0.981).

CONCLUSIONS

The present study showed patients having stenting to the proximal LAD could potentially benefit from the experimental strategy with lower ischaemic events without a trade-off in major bleeding at two years.
