The paper analyzes the immediate and long-term results of point stenting in patients with extended (more than 30 mm) coronary stenoses and compares them with those obtained by routine stenting. The study included 177 patients with varying extent stenoses who underwent traditional implantation of intracoronary stents. Thirty-seven patients undergone the so-called point stenting formed a separate group. There was no significant difference in clinical and angiographic success rates between the patients of all three groups. Significant difference was also absent in subacute stent thrombosis between the patients of Groups 2 and 3 and those of the point stenting group. Thus, acute or subacute stent thrombosis was noted in 4 (2.3%) patients from the routine stenting groups, all the patients being from Groups 2 and 3, and in 2 (5.4%) from the point stenting group. No significant difference was found in the incidence of recurrent angina pectoris (restenosis) between Groups 1 and 2 and between Groups 2 and 3. At the same time, recurrent angina (restenosis) significantly more frequently developed in the patients of Group 3 than those of Group 1. As compared with Groups 2 and 3 patients, there was no significant difference in the incidence of recurrent angina (restenosis).
本文分析了冠状动脉狭窄长度超过30毫米的患者进行点状支架置入术的近期和长期结果，并将其与常规支架置入术的结果进行比较。该研究纳入了177例不同程度狭窄的患者，这些患者接受了冠状动脉内支架的传统植入术。37例接受所谓点状支架置入术的患者组成了一个单独的组。所有三组患者的临床成功率和血管造影成功率均无显著差异。第2组和第3组患者与点状支架置入术组患者之间在亚急性支架血栓形成方面也没有显著差异。因此，常规支架置入术组中有4例（2.3%）患者出现急性或亚急性支架血栓形成，所有这些患者均来自第2组和第3组，点状支架置入术组中有2例（5.4%）出现急性或亚急性支架血栓形成。第1组和第2组之间以及第2组和第3组之间在复发性心绞痛（再狭窄）发生率方面未发现显著差异。与此同时，第3组患者复发性心绞痛（再狭窄）的发生频率明显高于第1组患者。与第2组和第3组患者相比，复发性心绞痛（再狭窄）的发生率没有显著差异。
