BACKGROUND: A longer stent length is known to be a predictor of adverse events after a percutaneous coronary intervention (PCI). However, the evaluation of the stent length on the outcome of ST-segment elevation myocardial infarction (STEMI) patients is not enough.
PATIENTS AND METHODS: A total of 686 STEMI patients who underwent primary PCI were divided into four groups according to the total stent length as follows: short (<18 mm, n=183), lower-medium (18-23 mm, n=256), upper-medium (24-31 mm, n=155), and long (≥32 mm, n=92). We compared the all-cause mortality, major adverse cardiovascular events (MACEs; composite of cardiovascular death, myocardial infarction, and stroke after discharge), target lesion revascularization, and target vessel revascularization with a median follow-up of 1213 days among these four groups.
RESULTS: There were no significant differences in MACEs (10.4% in the short, 7.0% in the lower-medium, 6.5% in the upper-medium, 7.6% in the long, P=0.633) among the different stent length groups. The all-cause mortality, target lesion revascularization, and target vessel revascularization also did not differ among the four groups. In the drug-eluting stent (n=237) and bare-metal stent subgroups (n=449), all outcomes were comparable among the groups. However, in the diabetes subgroup (n=265), the rate of MACEs was higher in the long group than in the other groups, although the difference was not significant (6.6% in the short, 9.6% in the lower-medium, 3.4% in upper-medium, 16.7% in long group, P=0.095).
CONCLUSION: A long stent length was not associated with adverse clinical outcomes in STEMI patients who underwent primary PCI.
