Abstract:
Objective To evaluate the effect of urapidil on myocardial reperfusion and cardiac function during primary percutenons coronary intervention (PCI) in acute myocardial infarction (AMI) patients.Methods 54 AMI patients undergoing primary PCI were randomized to intracoronary urapidil (n=27) and nitroglycerin (n=27) group.When blood flow grade TIMI-l or more appeared in the infarct related artery (IRA) before or after percutenous transluminal coronary angioplasty (PTCA),urapidil (12.5 mg) or nitroglycerin (0.2 mg) was given intracoronary and then stents were implanted as needed.TIMI blood flow,no reflow/slow floW,corrected TIMl frame count (cTFC),myocardial blush grade (MBG),ST resolution (STR) on ECG, peak of creatine kinase (CK),cardiac troponin T (cTnT) were observed before and after PCI.Left ventricular ejection fraction (LVEF) was measured 24 hours and 30 days after PCI and MACE including death,reinfartion,revascularization in hospital were observed. Resuits Urapidil group compared to the nitroglycerin group,cTFC (18.38±3.30 vs.21.44±4.26,P=0.005) decreased and MBG (P=0.040) improved.STR in the urapidil group improved significantly compred to the nitroglycerin group (93% vs.70%,P=0.038).LVEF of 24 hours and 30 days after PCI in the urapidil group was higher than that ofthe nitroglycerin group (0.55±0.05 vs.0.52±0.06,P=0.021 and 0.58±0.06 vs 0.54±0.06,P=O.041,respectively).Peak CK (1895.26±1239.02 vs.1269.96±515.84,P=0.021) and peak TnT (5.81±5.27 vs 3.64±2.35,P=0.050) in the urapidil group decreased more significantly than that of the nitroglycerin group.No difference of MACE was found in the two groups.Conclusion Intracoronary urapidil administration adjunct to primary PCI in AMI ameliorates coronary blood flow and myocardial perfusion, improves ventricular function,and reduce the infarct size and does not incllase the incidence of complications during hospitalization.
