摘　　要：目的应用心脏彩超检测技术评价急性心肌梗死(AMI)后不同时间段心室重塑的程度并探讨该技术的临床价值。方法回顾性分析2019年1月至2019年8月在泰安市中心医院心内科住院首次发生AMI的87例患者。所有研究对象于AMI后第1天、第7天、第1个月和第6个月分别用应用心脏彩超测量左心室舒张末期容积指数(LVEDVI)。第7天、第1个月和第6个月LVEDVI与第1天LVEDVI差值为⊿LVEDVI,发生心室重塑标准:⊿LVEDVI≥5 mL/m^2,⊿LVEDVI<5 mL/m2定义为未发生心室重塑。结果所有研究对象在6个月的随访中,无论是否急症再灌注治疗,均于AMI后出现心室重塑。急症再灌注患者第7天、第1个月及第6个月⊿LVEDVI较第1天逐渐增大,差异有统计学意义(P<0.05)。未行急症再灌注患者第7天、第1个月及第6个月⊿LVEDVI较第1天亦逐渐增大,差异有统计学意义(P<0.05)。随着时间的延长,心室重塑的程度逐渐加重,AMI后1个月心室重塑的速度降低,但仍在发展。未行急性再灌注治疗患者心室重塑程度较行急性再灌注治疗患者明显。结论AMI后心室重塑会持续存在,心脏彩超在评价AMI心室重塑中准确、可靠、方便,是一种很好的无创检测方法,值得临床推广应用。【Objective】To evaluate the degree and value of ventricular remodeling in different time after acute myocardial infarction(AMI)by color Doppler echocardiography.【Methods】Eighty-seven patients with first AMI were analyzed retrospectively.All patients were measured by left ventricular end diastolic volume index(LVEDVI)on the first day,the seventh day,the first month and the sixth month after AMI.The difference between LVEDVI on the seventh,the first month,the sixth month and the first day was⊿LVEDVI.If⊿LVEDVI is equal to or greater than 5 mL/m2,it is defined as the occurrence of ventricular remodeling;if⊿LVEDVI is less than 5 mL/m2,it is defined as the absence of ventricular remodeling.【Results】All patients had ventricular remodeling after AMI.With the increase of time,the degree of ventricular remodeling gradually increased.The degree of ventricular remodeling in patients with acute reperfusion was lower than that in patients without acute reperfusion.【Conclusion】The ventricular remodeling will continue to exist after AMI.Color Doppler echocardiography is an accurate,reliable and convenient noninvasive method in the evaluation of AMI ventricular remodeling.
