Demand Ischemia vs Type 2 MI Demand ischemia is an inexact term that is frequently used incorrectly. In hypotension or hypovolemia. Demand ischemia is a physiologic description that should be used when the demand for myocardial oxygen is greater than the supply supply-demand mismatch. Providers use this term inconsistently some meaning a myocardial infarction did occur others to indicate an episode of demand ischemia.
