Treatment of Slow-Flow After Primary Percutaneous Coronary Intervention With Flow-Mediated Hyperemia: The Randomized RAIN-FLOW Study.Background ST-segment-elevation myocardial infarction complicated with no reflow after primary percutaneous coronary intervention is associated with adverse outcomes.  Methods and Results In the RAIN-FLOW (Treatment of Slow-Flow After Primary Percutaneous Coronary Intervention With Flow-Mediated Hyperemia) study, 67 patients with ST-segment-elevation myocardial infarction and no reflow were randomized to receive either pharmacologic-mediated hyperemia with intracoronary adenosine or nitroprusside (n=30) versus flow-mediated hyperemia (n=37).
