[Results of point stenting of extended coronary stenoses in patients with ischemic heart disease].
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).
