Long-term follow-up of primary stenting with coil stent in acute myocardial infarction.
The authors evaluated clinical and angiographic outcomes for 1 year after primary stenting using coil stent for acute myocardial infarction. Twenty-eight patients underwent primary stenting with coil stent. Follow-up coronary arteriography at 3 months and 1 year was planned in all patients. Procedural success was achieved in 96%. There was no acute or subacute thrombosis. Minimal lumen diameter (MLD) was increased from 0.08 +/- 0.19 to 2.73 +/- 0.49 mm after stenting. MLD had decreased significantly for 3 months (MLD at 3 months: 2.03 +/- 0.86 mm, p = 0.001). On the other hand, MLD did not differ between 3-month; and 1-year follow-up (MLD at 1 year: 2.26 +/- 0.73 mm, p = NS). Only one patient manifested reocclusion at 3-month follow-up. The cumulative restenosis rate and target lesion revascularization rate at 1-year follow-up were 25.9% (7/27) and 11.1% (3/27). Primary stenting using coil stent is safe and feasible in patients with acute myocardial infarction and may improve clinical outcome and decrease restenosis and target lesion revascularization rate.
