Comparison of combination therapy of adenosine and nitroprusside with adenosine alone in the treatment of angiographic no-reflow phenomenon

We sought to compare the combination therapy of adenosine and nitroprusside in no-reflow phenomenon during percutaneous coronary intervention. Improvement in coronary flow from no-reflow to postdrug state was evaluated. Patients who received adenosine (n = 21) were compared to ones who received the combination of adenosine and nitroprusside (n = 20) for treatment. Improvement of TIMI flow grades was higher in the group that received combined therapy (1.5 +/- 1.0 vs. 0.8 +/- 0.6; P < 0.05). Combination therapy of adenosine and nitroprusside is safe and provides better improvement in coronary flow compared to intracoronary adenosine alone in case of impaired flow during coronary interventions.
