  • OBJECTIVE: Applying shock waves to the heart has been reported to stimulate the heart and alter cardiac function. We hypothesized that shock waves could be used to diagnose regional viability.METHOD: We used a Langendorff model to investigate the acute effects of shock waves at different energy leve

  • Lipoteichoic acid (LTA) is the key pathogenic factor of gram-positive bacteria and contributes significantly to organ dysfunction in sepsis, a frequent complication in critical care patients. We hypothesized that LTA directly affects cardiomyocyte function, thus contributing to cardiac failure in se

  • Milrinone and levosimendan administered after reperfusion improve myocardial stunning in swine

  • Scandinavian Cardiovascular Journal 47(1), 50-57, 2013-02
  • … We assessed the effect of milrinone application timing after reperfusion against myocardial stunning as compared with levosimendan in swine. … Regional myocardial contractility was assessed by percent segment shortening (%SS). … Milrinone should be administered just after reperfusion to protect myocardial stunning through p38 MAPK, whereas levosimendan improvement of contractile function could be mainly dependent on its positive inotropic effect. …

Myocardial contractility represents the intrinsic ability of the heart/myocardium to contract. Changes in the ability to produce force during contraction result from incremental degrees of binding between myosin (thick) and actin (thin) filaments.
