    Abstract:
    A multicentre study of the localization of myocardial infarction (MI) using ECG and 2-dimensional echocardiography (Echo-2D) was performed on the 21st day of the onset of MI. The study population consisted of 650 pts (mean age 55.0 years), 553 males and 97 females. The purpose of the study was: 1) to compare the site of MI as diagnosed by ECG and Echo-2D, 2) to determine the controversies in the diagnosis between these two methods. Consistent results of both methods were obtained in 408 pts (62.8%) of the group. In 61 pts (9.4%) the diagnosis of MI by ECG and Echo-2D was undefined. In 181 pts (27.8%) the inconsistencies of ECG and Echo-2D evaluations were demonstrated; in 106 pts ECG changes were undefined, but evident Echo-2D changes were found; on the contrary, in 51 pts MI diagnosed by ECG was not confirmed by Echo-2D. In 24 pts entirely inconsistent results were shown. 209 pts (32%) with myocardial contractility disorders in the apical region of the heart diagnosed by Echo-2D showed different MI localisation as determined by ECG: 147 pts had anterior or antero-lateral MI, 28 pts--postero-inferior MI, 12 pts--apical MI and 22 pts--another one. By these findings it has been shown that ECG and Echo-2D are compatible methods but not replaceable ones.
