  		Figure 1 Relationship between microvascular integrity within the initial RA and clinical outcome. The horizontal axis is the RA ratio before recanalization, while the vertical axis is PGSR one day after recanalization. The upper panel (A) shows major cardiac events (cardiac death, myocardial reinfarction or repeat admission for congestive heart failure). Major cardiac events (solid circles) often occurred for those patients whose RA ratio was high (>0.45) and whose PGSR was relatively low (≤0.46). Open triangles represent patients for whom no major cardiac events were noted. The middle panel (B) shows target lesion revascularizations (solid triangles). The lower panel (C) shows composite cardiac events (solid squares).

  		Figure 2 Receiver operator characteristic curve for major cardiac events (cardiac death, myocardial reinfarction or repeat admission for congestive heart failure) using MCE on day 1 (open circles) and MCE on day 2 (open squares). The area under the curve for day 2 is larger than that for day 1. Myocardial contrast echocardiography on day 2 was more useful for predicting subsequent major cardiac events after reperfusion therapy.
