In the intensive care unit (ICU), except for patients with ischemic heart disease, we may not address the circulatory status of critically ill patients regarding the diastolic blood pressure. Systolic blood pressure affects arterial bleeding and cardiac afterload, mean blood pressure is related to organ perfusion, and diastolic blood pressure is a determinant of coronary blood flow. However, if the diastolic blood pressure is high, will coronary blood flow increase and is it advantageous for cardiac function? Is there a specific adequate diastolic blood pressure in critically ill patients in the ICU? We approach this difficult clinical question from a physiological point of view.
