title: Coronary artery stenting in acute myocardial infarction.
abstract: Little information is available on the use of coronary stents to treat suboptimal results during direct angioplasty in acute myocardial infarction (AMI). In this study, we report 16 cases of AMI who underwent stent implantation in infarct-related artery for suboptimal results and their 6 months angiographic follow-up. Immediate angiographic success was achieved in all patients. The minimal luminal diameter increased from 0.06 +/- 0.12 mm to 2.89 +/- 0.12 mm (p < 0.001). One patient died in the hospital on day 8 due to subacute stent thrombosis. No patient required emergency bypass surgery. Two patients required blood transfusion for groin haematoma and one required intracoronary thrombolysis. All patients underwent exercise stress test at 1 month and at 3 months and coronary angiography at 4 months or earlier it indicated. At the end of 6 months follow-up, 4 patients had a positive exercise test and coronary angiography revealed angiographic restenosis in 3 and progression of disease in other vessels in 1 patient. We conclude that stent deployment is a viable option to treat suboptimal results after direct angioplasty in AMI.
