[Clinical and prognostic significance of disturbed global and regional contractility of left ventricle in diphtheria myocarditis].
Examination of 159 diphtheria patients diagnosed myocarditis in 64 of them. The latter were divided into 3 groups: with mild, moderate and severe myocarditis. The patients with and without diphtheria have undergone two-dimensional echocardiography with estimation of the asinergia index (AI) and left ventricular (LV) ejection fraction. Pronounced systolic dysfunction was revealed only in severe diphtheric myocarditis (DM). AI rose in moderate and severe DM. By the degree of AI elevation it can be judged about myocarditis severity and the disease prognosis. Regional LV contractility and LV systolic dysfunction were correlated. A group of patients with severe DM was identified who had a high risk of death in akinesia of LV segments (IA > 2) and lowering of LV ejection fraction below 35%.
