The study by Wang and colleagues [1] demonstrates that when the Na/H exchange inhibitor cariporide and the ß-blocker metoprolol are given together prior to ischemia, infarct size is limited more than by cariporide alone. This result could become very important in improving treatments to limit ischemia/reperfusion (I/R) injury. However, because the model exposes the heart to exceedingly high left ventricular end-diastolic pressure (EDP), there may be problems extrapolating to clinical situations.
To reiterate, the model used by Wang and colleagues [1] and many others includes a water-filled left ventricular balloon that is filled to give a baseline EDP of 0 to 5 mm
