To explore the impact of intracoronary bolus administration of tirofiban combined with nitroprusside through thrombus aspiration catheter or thrombus aspiration alone on myocardial reperfusion and major adverse cardiovascular events rate in acute anterior myocardial infarction patients with heavy thrombosis burden.Ninety consecutive acute anterior myocardial infarction patients with heavy thrombosis burden [(59.8 ± 11.5) years old] were randomly assigned to thrombus aspiration group (Group A, n = 30), thrombus aspiration and intracoronary tirofiban bolus (25 µg/kg prior to the first balloon inflation,Group B, n = 30), thrombus aspiration and intracoronary tirofiban combined with nitroprusside bolus (200 µg prior to the first balloon inflation, Group C, n = 30) with random number table. Baseline clinical data, angiographic features before and after percutaneous coronary intervention (PCI) and major adverse cardiovascular events after PCI between 3 groups were compared.The baseline clinical data and angiographic features among 3 groups were similar (all P0.05) . The time of pain to balloon was (5.5 ± 3.8) hours. After primary PCI, myocardial tissue perfusion was significantly better in Group C than in Group A and Group B: TMP grade3 [10.0% (3/30) vs. 40.0% (12/30) and 33.3% (10/30), P0.01 and P0.05]. Left ventricular ejection fraction at 5 to 7 days after PCI also tended higher in Group C than in the other 2 groups (P = 0.05). One patient died of heart failure at 7th day after PCI in Group A, and no patient died in Group B and C. Thirty days after PCI, there was no re-myocardial infarction and target vessel revascularization event among 3 groups. The bleeding complication rate during 30 days follow-up was similar among 3 groups (P0.05) .Intracoronary bolus application of tirofiban combined with nitroprusside through thrombus aspiration catheter after thrombus aspiration is associated with an improvement of myocardial reperfusion without increasing bleeding complication and other adverse cardiovascular events rate compared with thrombus aspiration alone in patients with acute anterior myocardial infarction and heavy thrombosis burden undergoing primary PCI. |
