Index of Microcirculatory Resistance: a new effective invasive tool to assess reperfusion after primary percutaneous coronary intervention for ST-segment elevation myocardial infarction.
Assessment of myocardial reperfusion during primary percutaneous coronary intervention for ST-segment elevation myocardial infarction remains challenging. The pressure wire-derived Index of Microcirculatory Resistance (IMR) is a parameter reflecting the microcirculation status. We illustrated with two cases the accuracy of the IMR in the setting of STEMI to predict myocardial damage as well as LV function recovery.
