Key result
Intracoronary stenting significantly reduced the rate of angiographic restenosis at six months compared with standard balloon angioplasty (18% vs 32%, P=0.03).

Absolute Event Rate: 18% vs 32%
p-value: p=0.03
Intracoronary stenting significantly reduces the rate of recurrent stenosis compared to standard balloon angioplasty in patients with restenosis after initial angioplasty, though it is associated with a higher risk of subacute thrombosis.
Erbel et al. (1998) conducted an RCT in Restenosis after initial balloon angioplasty (n=383). Intracoronary stenting with a Palmaz-Schatz stent vs. Standard balloon angioplasty was evaluated on Angiographic evidence of restenosis (defined as stenosis of more than 50 percent of the luminal diameter) at six months (p=0.03). Intracoronary stenting significantly reduced the rate of angiographic restenosis at six months compared with standard balloon angioplasty (18% vs 32%, P=0.03).
