摘要
目的:应用心脏磁共振检查(MRI)评价心功能,应用心脏MRI心肌灌注延迟显像评价心肌坏死情况,为临床诊断和治疗提供依据。方法:将42例急性心肌梗死患者分为急诊PCI组(22例)和静脉溶栓组(20例)。所有患者于发病后第4周行心脏MRI检查及心肌灌注延迟显像,根据心脏MRI检查计算左室功能参数,根据心肌延迟强化的透壁程度进行视觉评分(VSM)评价心肌梗死范围。结果:急诊PCI组和静脉溶栓组中VSM总分分别与射血分数(EF)、收缩末期容积(EDV)、收缩末期容积指数(EDVI)、舒张末期容积(ESV)、舒张末期容积指数(ESVI)密切相关(P<0.001)。结论:应用心脏MRI可以全面评价心脏情况。
Objective：To evaluate heart function through heart magnetic resonance imaging （MRI）and determining size of myocardial infarction through delayed enhancement magnetic resonance imaging（DE-MRI）. Methods：42 Patients with acute myocardial infarction were divided into pereutaneous coronary intervention （PCI）group （n=22）and vein thrombolysis group（n=20）. On the 4th week, all patients accpeted heart MRI and DE-MRI. Parameters of left ventrieular function were got through calculating, and the size of myocardial infarction was got through vision scoring method（VSM）. Results：There were correlation between VSM and ejection fraction, end-diastolic volumes, end-diastolic volumes index, end-systolic vol- umes,end-systolic volumes index,respectively. Conclusion：Heart MRI can give an overall assessment of the patient＇s heart information.
