摘　　要：目的:比较彩色超声心动图与高分辨率CT对早期左心功能不全的诊断价值。方法:选取72例左心功能不全患者,采用彩色超声心动图及高分辨率CT进行检查,随访18个月,比较两种检查方法的左心功能检测值。结果:经18个月随访复查发现,彩色超声心动图诊断准确率为95.8%(69/72),高分辨率CT诊断准确率为97.2%(70/72),两种检测方法的诊断准确性均较高,且差异无统计学意义(x2=0.207,P>0.05)。彩色超声心动图和高分辨率CT对各项心功能指标,即每搏输出量(LVSV)、左室射血分数(LVEF)、左室舒张末期容积(LVEDV)以及左室收缩末期容积(LVESV)等的检测结果相似,且差异均无统计学意义(t=-0.775,t=1.387,t=-0.624,t=-1.209;P>0.05)。结论:彩色超声心动图与高分辨率CT对早期左心功能不全的诊断准确性均较高。Objective： To compare the diagnosis value of color echocardiography and high resolution CT for early left ventricular dysfunction. Methods： 72 cases of left ventriculardysfunction patients in our hospital were chosen, and all of patients were detected with color echocardiography and high resolution CT inspection. Each patient was followed-up for 18 months and then to compare the diagnosis values of the two kind methods. Results： After 18 months follow-up review, the diagnostic accuracy of color echocardiography and high resolution CT were 95.8%（69/72） and 97.2%（70/72）, respectively. Both of two methods were higher, and the difference was not statistically significant（x2=0.207, P=0.649）. All sorts of cardiac function detection result, such as LVSV, LVEF, LVEDV and LVESV, were similar between color echocardiography and highresolution CT, and the difference was not statistically significant（t=-0.775, t=1.387, t=-0.624, t=-1.209; P〉0.05）. Conclusion： Both of the diagnostic accuracy of color echocardiography and high-resolution CT for early left ventricular dysfunction were higher. All of them are worthy generalization and applying in clinical diagnosis for early heart failure.
