Acute Effects of Intracoronary Tirofiban on No-Reflow Phenomena in Patients With ST-Segment Elevated Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

We evaluated the acute effect of intracoronary administration of tirofiban on no-reflow phenomenon in patients with ST-segment elevated myocardial infarction undergoing primary percutaneous coronary intervention. Consecutive patients (n = 162) were randomized into 2 groups based on whether intracoronary tirofiban was administered. After the administration of intracoronary tirofiban, thrombolysis in myocardial infarction (TIMI) flow grade significantly increased (P < .001) and successful reperfusion was achieved in 26 (32%) patients. In the placebo group, however, after the administration of intracoronary placebo the TIMI flow grade did not change (P = .070), and successful reperfusion was achieved only in 8 (10%) patients. In-hospital major adverse cardiac events (MACE) were significantly lower in the tirofiban group (36% vs 19%, P = .013). Intracoronary administration of tirofiban significantly improves TIMI flow grade and is associated with a lower in-hospital rate of MACE.
