Abstract

The immediate outcome of 271 procedures involving the intracoronary implantation of 305 stents was determined. Data were analyzed with regard to indication for stenting and stent size. Elective indication was associated with a higher success rate than emergency indication (95.6% vs. 86.6%, P = 0.013) and a lower Q-wave infarction rate (0 vs. 6.4%, P = 0.006). Univariate analysis showed that the odds ratio for procedural success was significantly favored by elective indication (3.37, P = 0.018) but was unrelated to stent size (1.10, P = 0.087). These findings were confirmed on multivariate analysis. The likelihood of Q-wave infarction was lower for elective placement (P = 0.0008) but was not related to size. Requirement for emergency bypass surgery, incidence of subacute closure, and death were not related to indication or to stent size on either univariate or multivariate analysis. Therefore, the immediate outcome of stent placement is related to the indication for stenting, but not to the size of stent implanted. Procedural success is significantly favored by elective indication.
