Popis: Purpose: To examine whether in a model of cardiogenic shock complicating left anterior descending (LAD) artery occlusion, changes in ventricular hemodynamics due to an intrapulmonary artery balloon counterpulsation (PABC) may be associated with improved short-term outcome at 150 minutes. Methods: Ten down size pigs weighing 35±5 kg of both sexes were sedated, intubated and mechanicallly ventilated. Myocardial infarction was induced by insertion of a vascular plug (Amplatzer®) into the proximal part of LAD. Medical treatment was chosen according to European Society of Cardiology (ESC) Guidelines of 2010. All animals had a counterpulsation balloon placed in the pulmonary artery trunk and the frequency of counterpulsation was set to 100/min, independent of the animal's heart rhythm. (In the test group (n=5), counterpulsation was started as soon as hemodynamic parameters worsened, i.e.: a) severe ventricular arrhythmia occurred, or b) mean blood pressure (MBP) dropped more than 30% compared to baseline, or c) cardiac output measured by Vigileo system decreased to less than 40% compared to baseline. The counterpulsation was maintained for 10 minutes. The control group (n=5) received no conterpulsation. Results: The test group had statistically significant improved short-term survival rates (100% vs 60%, p
