MUSCULAR BRIDGES AS PREDICTORS OF STENT THROMBOSES

Abstract

Aim. To study the influence of muscular bridges on the stent thromboses in the anterior descending artery. Materials and methods. The study included 209 patients, who underwent interventional coronary interference in the anterior descending artery. Group 1 (main) engaged 87 patients with “muscular bridges” confirmed by coronarography data. Group 2 (control) included 122 patients without the above mentioned anatomic anomaly (all patients of the control group were randomly chosen). The results, obtained since 2007, when the primary transcutaneous coronary intervention (TCCI) was carried out, were assessed. Results. While studying the indices, it was established that the repeated restenoses in the arterial stents did not differ in the main and the control groups. However, 6 patients of the main group after TCCI had repeated thromboses in the inserted stents. In the control group, 2 cases of acute thromboses prior to and after TCCI were fixed. When using nonparametric statistical criteria (chi-square criterion), differences in both groups were found to be significant ( p < 0,05). Conclusions. The number of thromboses in the arterial stents with muscular bridges tended to increase - 6 clinical cases in the main group versus 2 cases in the control. So, a new and deeper investigation of this problem with respect to anatomic variants of intramyocardial location of the coronary arteries is to be performed.
