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.
确定了271例涉及冠状动脉内植入305个支架的手术的即时结果。对有关支架植入指征和支架尺寸的数据进行了分析。择期植入指征与高于急诊植入指征的成功率相关（95.6%对86.6%，P = 0.013），且Q波梗死率较低（0对6.4%，P = 0.006）。单因素分析显示，择期植入指征显著有利于手术成功的优势比（3.37，P = 0.018），但与支架尺寸无关（1.10，P = 0.087）。多因素分析证实了这些发现。择期植入时Q波梗死的可能性较低（P = 0.0008），但与尺寸无关。急诊搭桥手术的需求、亚急性闭塞的发生率和死亡在单因素或多因素分析中均与植入指征或支架尺寸无关。因此，支架植入的即时结果与支架植入指征有关，但与植入支架的尺寸无关。择期植入指征显著有利于手术成功。
