Shock can be caused by problems with the heart itself (cardiogenic shock), conditions that block blood flow to or from the heart (extracardiac obstructive shock), severe loss of fluids (hypovolemic shock), or abnormal flow of fluids into the tissues, despite normal or increased heart function (distributive shock).
Depending on the cause of shock, surgery may be required to repair heart valves or rupture of a ventricle, artificially augment blood flow from the heart, or remove an embolism.
