Abstract

Results of trials using the ACS MULTI-LINK (ML) stent, one of the new generation stents, were similar to or slightly better than those of trials using the Palmaz-Shatz stent. The purpose of this study was to evaluate relatively long-term (2 years) clinical outcomes of patients with coronary artery disease treated with the ML stent and to determine independent factors correlated with target lesion revascularization and cardiac events. The present study consisted of 82 consecutive patients who had undergone successful coronary ML stent implantation from January 1997 to December 1999. During the follow-up period, cardiac events occurred in 16 (19.5%) patients. All patients underwent follow-up angiography and 12 (14.6%) of the 82 patients underwent target lesion revascularization. Multiple logistic regression analysis showed that aggregation of risk factors (≥3 risk factors) (p=0.0274, odds ratio=5.14) and percent diameter stenosis >20% (p=0.0395, OR=4.586) were the significant explanatory factors of target lesion revascularization. In addition, aggregation of risk factors (≥3 risk factors) exhibited a tendency to correlate with cardiac events (p=0.0528) on multiple logistic regression analysis. The results of the present study suggest that target lesion revascularization after coronary ML stent implantation was influenced by aggregation of major coronary risk factors and residual percent diameter stenosis and that long-term clinical outcome is influenced by the aggregation of risk factors.
