Vascular shock occurs when blood volume is normal but vasomotor tone is suddenly lost, causing extreme vasodilation. The massive vasodilation event leads to a drastic and dangerous drop in blood pressure. Vascular shock can be triggered by anaphylaxis, septic shock, and by certain bacterial toxins. Hypovolemic shock is a result of large-scale blood loss; it is the most common form of circulatory shock. Cardiogenic shock is a result of heart failure or damage; it can result from multiple myocardial infarcts (heart attacks).
