【摘要】 目的探讨急性ST段抬高型心梗急诊经皮冠状动脉介入术(PTCA)中无复流现象与左心功能恢复的关系。方法用前瞻性队列研究的方法分析60例初发急性ST段抬高型心梗患者,病例分为无复流组(16例)和皮冠状动脉介入术(PC I)后TIM I血流3级组(44例),随访6个月,用三维彩色多普勒测量两组射血分数(LVEF),用脉冲多普勒组织成像技术(PW-DTI)测量并计算两组Em/Am值,以此来评价两组左心功能恢复的情况。结果PC I后冠状血流正常组6个月时EF值和Em/Am值高于无复流组(P<0.05)。结论无复流现象提示,AM I左心功能恢复不良。更多还原

【Abstract】 Objective This research investigates the relationship between no reflow phenomenon within ST elevated myocardial infarction(STEMI) after primary percutaneous coronary intervention(PCI) and the recovery of left ventricular functional.Method 60 patients with STEMI after primary PCI were analysed using forward cohort study.The patients are divided into two groups.Sixteen patients with no-reflow and forty-four patents with TIMI 3 class were studied.All patients underwent 3D echocardiograpy and Doppler tissues image(DTI) 6 months later.To compare left ventricular ejection(LVEF) and Em/Am.Results there are significant difference in LVEF and Em/Am between two groups(P〈0.05).Conclusion no reflow phenomena indicates that the recovery of left ventricular functional is unsuccessful.更多还原
