Coronary stenting decreases restenosis in lesions with early loss in luminal diameter 24 hours after successful PTCA.

BACKGROUND: Early loss of minimal luminal diameter (MLD) after successful percutaneous transluminal coronary angioplasty (PTCA) is associated with a higher incidence of late restenosis. METHODS AND RESULTS: Sixty-six patients (66 lesions) with > 0.3 mm MLD loss at 24-hour on-line quantitative coronary angiography were randomized into two groups: 1, Gianturco-Roubin stent (n = 33) and 2, Control, who received medical therapy only (n = 33). All lesions were suitable for stenting. Baseline demographic, clinical, and angiographic characteristics were similar in the two groups. Restenosis (> or = 50% stenosis) for the overall group occurred in 32 of 66 patients (48.4%) at 3.6 +/- 1-month follow-up angiography. Restenosis was significantly greater in group 2 than in group 1 (75.7% versus 21.2%, P < .001). Vascular complications (21.2% versus 0%) and length of hospital stay (7.3 +/- 1 versus 2.4 +/- 0.5 days, P < .01) were higher for the stent group. Although at follow-up there were no differences in mortality or incidence of acute myocardial infarction between the two groups, patients in the control group had a higher incidence of repeat revascularization procedures (73% versus 21%, P < .001). CONCLUSIONS: In patients with successful PTCA but reduced luminal diameter demonstrated by repeat angiography at 24 hours, the Gianturco-Roubin stent appears to reduce angiographic restenosis at follow-up.[1]
