Table 5. Theoretical model to evaluate success for no-reflow and reperfusion injury treatment.

Treatment	Myocardial Blush	ST	No-reflow/Reperfusion injury
	+	↓	Success/Success
	+	↑	Success/Failure
	−	↑	Failure/?
a	?	↑	?/Failure
a	?	↓	?/Success

^aThe existence of the latter two possibilities in this table is explained if one can evaluate a treatment for reperfusion injury by administering it by a microcatheter, balloon over the wire, or other similar device that can administer treatment before acting on the epicardial occlusion.
