磁共振成像与超声心动图评价心衰患者左心室结构、功能的比较

摘要

目的：比较心脏磁共振(CMRI)与超声心动图(UCG)对心衰患者左心功能的评估价值。方法：对34例纽约心功能Ⅲ级患者进行CMRI和UCG检查，计算左室的室间隔厚度(IVST)、左室后壁厚度(LVPWT)、舒张末期内径(EDD)、收缩末期内径(ESD)、左心室收缩末期容积(ESV)、舒张末期容积(EDV)以及左心室射血分数(LVEF)，配对比较，并进行相关性分析。结果：CMRI测得IVST、LVPWT、EDD、ESD、EDV、ESV、LVEF值分别为(8.6±1.8)mm、(8.6±2.2)mm、(58.2±3.2)mm、(35.3±3.6)mm、(194.64±37.20)ml、(140.15±33.00)ml、(42.12±6.59)%；UCG测得IVST、LVPWT、EDD、ESD、EDV、ESV、LVEF值分别为：(9.2±2.1)mm、(9.3±1.8)mm、(59.7±5.9)mm、(34.1±4.8)mm、(202.34±34.59)ml、(148.14±41.78)ml、(44.75±7.57)%，两种方法测量结果均呈正相关(r=0.843，P<0.05；r=0.784，P<0.05；r=0.786，P<0.05；r=0.730，P<0.05；r=0.812，P<0.05；r=0.764， P<0.05；r=0.831，P<0.05)。结论：磁共振成像可以准确评估心衰患者结构与功能，可用于疾病诊断与疗效监测。%Objective:To compare the evaluation of cardiac magnetic resonance and ultrasonic echocardiography in assessing the struture and function in heart failure patients.Method:CMRI and UCG examinations were performed on 34 patients with grade III of New York heart function,calculated left ventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),end diastolic diameter(EDD),end systolic diameter(ESD),left ventricular end systolic volume(EDV),end diastolic volume(ESV),and left ventricular ejection fraction(LVEF),paired comparison and correlation analysis.Result:CMRI measured IVST, LVPWT,EDD,ESD,EDV,ESV,LVEF values were(8.6±1.8)mm,(8.6±2.2)mm,(58.2±3.2)mm,(35.27±3.6)mm,(194.64±37.2)ml,(140.15±33.0)ml, (42.12±6.59)%;UCG measured IVST,LVPWT,EDD,ESD,EDV,ESV,LVEF values were(9.2±2.1)mm,(9.3±1.8)mm,(59.7±5.9)mm, (34.12±4.8)mm,(202.34±34.59)ml,(148.14±41.78)ml,(44.75±7.57)%,the results of the two methods were positively correlated(r=0.843,P<0.05;r=0.784,P<0.05;r=0.786,P<0.05;r=0.730,P<0.05;r=0.812,P<0.05;r=0.764,P<0.05;r=0.831,P<0.05).Conclusion:CMRI can accurately assess the structure and function of patients with heart failure,can be used for disease diagnosis and curative effect monitoring.
