Cardiac beta-adrenergic neuroeffector systems in acute myocardial dysfunction related to brain injury. Evidence for catecholamine-mediated myocardial damage.

abstract：BACKGROUND:Inhibition of fibrinolysis attributable to elevated concentrations of plasminogen activator inhibitor type 1 (PAI-1) in blood is associated with insulin resistance, hyperinsulinemia, and type 2 diabetes mellitus. Because we have shown that insulin can stimulate PAI-1 synthesis in vivo and because accelerated...
