[Left ventricular systolic function in patients with infectious allergic myocarditis].

Examination of 26 patients with infectious-and-allergic myocarditis and of 12 cases with myocarditic cardiosclerosis, performed with the aid of radionuclide ventriculography revealed signs of impairement of left ventricular systolic function, with both end-systolic volume and the mean myocardial fiber circular shortening rate measurements showing a downward tendency. A relationship was established between alterations in systolic function of the heart and clinical pattern of the medical condition.
