title: [Diagnostic significance of a change in the contractile function of the interventricular septum in ischemic heart disease (based on echocardiographic data)].
abstract: Echocardiography was conducted in 169 patients with ischemic heart disease (atherosclerotic and postinfarction cardiosclerosis, angina pectoris, unstable angina pectoris, myocardial infarction) to determine the diagnostic importance of changes in the contractile function of the interventricular septum (IVS). It is shown that no essential changes in IVS contractility detectable by echocardiography are encountered in patients with ischemic heart disease in a period clear of exacerbation. During an attack of angina pectoris, a decrease of the mean normalized rate of IVS systolic displacement is recorded, which suggests indirectly a lesion of the left anterior descending artery. IVS contractile function increases in the pre-infarction period, which is a compensatory reaction to the changes in the contractile function of the left ventricle.
