Background. At last time there are papers about the disparity of MI location and wall motion abnormalities (WMA). EchoCG criteria of necrosis site are doubtful. Their revision must be not only negative, but must lead to another reception of gotten information.
The aim is to have seen the clinical interpretation of WMA at patients with STEMI treated by PCI according to coronary artery occlusion site.
Materials and methods. 17 patients with primary STEMI treated by PCI were studied. EchoCG were performed by 4-5 day after intervention. According to occlusion site (RCA, LAD, LCx) all patients were divided to 3 groups.
Results. The analyses of WMA of the left ventricle did not show any significant difference between groups. Hypokynesia and akynesia were found both in zone of supplying from infarct-related artery and in other areas. At the same time it was a tendency to develop primary apical or basal types of WMA. At some patients another type of WMA, called intermediate, was defined, which included equally moderate disorders in apical and basal areas. Probably the total type of WMA exists by analogy with intermediate one with sever local changes.
Conclusion. The problem of EchoCG estimation of WMA probably contains our interpretation of gotten data, not the method’s imperfections. WMA does not complete depend on coronary artery occlusion site and is not as absolute as it got used. Myocardium contraction is a dynamic system explained by conception of infarction heart.
