Restenosis Stent Trial - REST
Stenting vs. PTCA for 6-month angiographic outcomes in restenosis.
To compare stenting versus balloon angioplasty for restenotic lesions.
Patients Screened: Not given
Patients Enrolled: Planned 400
Mean Follow Up: 6 months
Native coronary artery lesions
Vessel size > 3mm
Lesion length < 20mm
6-month angiographic restenosis rate
Major adverse clinical events at 6 months
Palmaz-Schatz stents vs. balloon angioplasty.
Preliminary results are available for the first 172 lesions treated; 85 were assigned to stenting and 87 to balloon angioplasty.
Pre-procedure MLD was similar for both groups (1.25 ± 0.44 mm stent, 1.25 ± 0.35 mm balloon). Post-procedure MLD was 3.12 ± 0.43 mm for the stent group, and 2.33 ± 0.57 mm for the angioplasty group. At 6 months, the follow-up MLD remained higher for the stent group (2.14 ± 0.66 mm vs 1.86+±0.56).
Binary restenosis rates were 11.7% for the stent group and 37.0% for the PTCA group.
Bleeding complications were slightly higher for the stent group (12.3%) compared to the angioplasty group (4.6%).
There was an incidence of subacute thrombosis of 3.5% in the stent group.
These preliminary results suggest that stenting in restenotic lesions improves angiographic outcomes at 6 months.
