International audience. Septic shock is an inflammatory response to an infection leading to cardiovascular dysfunction. Today, only few studies have evaluated whether cardiac dysfunction in septic shock is due to load modifications, neuroendocrine influence or intrinsic cardiac alterations. The isolated working heart approach allows measurement of cardiac function under controlled conditions. Our study demonstrated for the first time that in septic shock rat, alteration of cardiac function is characterized by both systolic and diastolic dysfunctions beside load conditions. This observation might help to apprehend the particular dysfunction associated with sepsis.
