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对比

摘要

Objective:To compare the diagnosis value of color echocardiography and high resolution CT for early left ventricular dysfunction.Methods:72 cases of left ventricular dysfunction 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 high-resolution 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.%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。
