ABSTRACT
OBJECTIVES:
This study sought to assess the late clinical and angiographic outcomes of patients who received stents within the first week of acute myocardial infarction (AMI).BACKGROUND:
Recent studies have demonstrated that stenting of the infarct-related artery is a useful adjunct to balloon angioplasty in patients with AMI. However, there are limited data on the late clinical and angiographic outcomes of these patients.METHODS:
Between January 1994 and September 1995, 32 patients at our institution underwent stenting of the infarct-related artery within 1 week of AMI 13 within 14 hours (evolving group) and 19 between days 2 and 7 (recent AMI group). Late clinical follow-up was obtained on all survivors. Quantitative angiographic measurements were recorded on the stented segments before stenting, immediately after stenting, and on the follow-up angiograms.RESULTS:
At 13.1+/-6.4 months from the time of stenting, three patients died and three required repeat angioplasty, but no patient had reinfarction or required bypass surgery. At follow-up 26 (81%) of 32 patients remained free of major cardiac events; of these, 24 (92%) were free of angina. Repeat angiography performed at 10.8+/-7.5 months in 26 (87%) of 30 discharged patients showed that all infarct-related arteries were patent and the restenosis rate was low 22% in the 13 patients with evolving AMI (<14 hours) and 12% in the 19 patients with recent AMI (days 2 through 7).CONCLUSION:
In this study stenting of the infarct-related artery in patients with evolving and recent AMI was associated with a favorable late clinical outcome. Patency of the infarct-related artery was well maintained, and the restenosis rate was low.
