  • Title: [Evaluation of clinical study methods in the diagnosis of cardiac insufficiency in myocardial infarct].
    Author: Gvatua NA, Kravtsov VL, Avdiushko BR, Aleksandrova LA, Semikhodskaia VI.
    Journal: Kardiologiia; 1976 Aug; 16(8):97-103. PubMed ID: 796541.
    Abstract:
    On the basis of an examination of 500 patients with myocardial infarction the authors undertook a critical analysis of the informativeness of some clinical methods of evaluation of the cardiac muscle contractility employed in this pathology. The authors concluded that attempts at assessing the contractility of the left ventricle on the basis of the temporal intervals of the mechanical systole alone may give misleading results in myocardial infarction patients. The dp/dtmax parameter cannot serve as an independent measure of the inotropic function since its changes largely depend on the conditions of the ventricular load.
