    Journal: Crit Care Med; 1984 Dec; 12(12):1021-3. PubMed ID: 6439470.
    Abstract:
    Comparative hemodynamic measurements recorded in 19 cases of septic shock associated with Neisseria meningitidis bacteremia and in 20 shock cases associated with bacteremia due to other Gram-negative bacilli showed a significantly higher incidence of early myocardial depression in the cases with meningococcal infection. Echocardiographic, ECG, and serum enzyme (CK-MB isoenzyme) studies closely correlated with impaired myocardial contractility and development of cardiogenic shock in patients with meningococcal bacteremia. Autopsy of the heart from three patients who succumbed to shock confirmed the presence of myocarditis with intracellular Gram-negative diplococci. Our observations suggest that the onset of cardiac dysfunction precedes clinical manifestations of shock.
