In the past 10 years there have been major advances in the treatment of cardiac arrest by the application of therapeutic hypothermia (TH). TH is a safe treatment option, providing the physiological effects are taken into consideration and providing the potential pitfalls of application of hypothermia are avoided. TH (32-34°C) is just as safe and effective as cooling to 36°C ('near-normal temperature'). The benefit of TH is thus probably derived from the effective suppression of fever. The broad spectrum of pathophysiological mechanisms by which therapeutic hypothermia exerts its effect on organism in a hypoxic situation suggests a potential wider role for this therapy than in current daily clinical practice. Cardiogenic shock is no longer regarded as a contraindication for TH; in the past few years the safety and effectiveness of this treatment have been proven in patients with cardiogenic shock. In fact, the anti-ischaemic and positive inotropic effects of TH suggest that this treatment could be a potential treatment specifically for patients with cardiogenic shock.

Cholestasis due to biliary obstruction can cause cardiogenic shock with bradycardia by delaying the elimination of arotinolol.
BMJ Case Rep

Cardiogenic shock with bradycardia due to beta-blockers is well-documented; however, this condition in association with arotinolol is unreported. We present a case of cardiogenic shock resulting from delayed arotinolol clearance caused by bile duct obstruction. A man in his 60s presented to our hospital with jaundice.

Background: The long-term effects of early left ventricular unloading after venoarterial extracorporeal membrane oxygenation (VA-ECMO) remain unclear.
Methods: The EARLY-UNLOAD trial was a single-center, investigator-initiated, open-label, randomized clinical trial involving 116 patients with cardiogenic shock (CS) undergoing VA-ECMO. The patients were randomly assigned to undergo either early routine left ventricular unloading by transseptal left atrial cannulation within 12 hours after randomization or the conventional approach, which permitted rescue transseptal cannulation in case of an increased left ventricular afterload.

Sepsis often leads to vasoplegia and a hyperdynamic cardiac state, with treatment focused on restoring vascular tone. However, sepsis can also cause reversible myocardial dysfunction, particularly in the elderly with pre-existing heart conditions. The Surviving Sepsis Campaign Guidelines recommend using dobutamine with norepinephrine or epinephrine alone for patients with septic shock with cardiac dysfunction and persistent hypoperfusion despite adequate fluid resuscitation and stable blood pressure.

Whilst Extra-Corporeal Membrane Oxygenation (ECMO) for circulatory support in patients with severe septic shock, commenced in newborn infants and children in the late 1980's, ECMO has remained a controversial treatment for adults with refractory septic shock (RSS). This is fundamentally due to differences in the predominant hemodynamic response to sepsis. In newborn infants and very young children ventricular failure called Low Cardiac Output Syndrome (LCOS) is the major hemodynamic response whilst adolescents and adults have mainly vasoplegic shock.
