Key result
Increased coronary stenting was associated with reduced adverse cardiac events at one year (22.8% vs 28.8%; RR 0.79; 95% CI 0.69-0.90; P<0.001), driven by less target-vessel revascularization.

The widespread adoption of coronary stenting in the mid-1990s significantly reduced the need for subsequent target-vessel revascularization at one year.
Rankin et al. (1999) conducted a cohort in Percutaneous coronary interventions (n=9,594). Coronary-artery stenting vs. Earlier period with lower stenting rate was evaluated on Adverse cardiac events at one year (RR 0.79, 95% CI 0.69-0.90, p=<0.001). Increased coronary stenting was associated with reduced adverse cardiac events at one year (22.8% vs 28.8%; RR 0.79; 95% CI 0.69-0.90; P<0.001), driven by less target-vessel revascularization.
