目的探讨多排螺旋CT应用于诊断早期左心功能不全中的临床价值。方法选择近五年我院收治的心脏疾病患者100例作为研究对象,对DR心脏三位片拟诊早期左心功能不全患者行胸部多排螺旋CT扫描及彩色超声心动图检查,对比分析患者后两种检查的结果。结果肺水肿并心功能不全患者的血管蒂宽度(VPW)、心胸比例(CTR)分别为(74.79±5.26)mm、(0.73±0.06),无肺水肿患者的VPW和CTR分别为(61.56±7.14)mm、(0.60±0.08);彩超与HRCT检查测得的LVEDV、LVESV、LVSV、LVEF结果差异无统计学意义(P>0.05),两种检查方法的左心功能指标相关性好,r值=0.42~0.88,P<0.05。结论多排螺旋CT和超声心动图对早期左心室功能评价方面没有明显差异,可用于诊断早期左心功能不全,在心脏功能不全患者的评价中有临床应用价值。
Objective To investigate the clinical value of multislice spiral CT in the diagnosis of early left ventricular dysfunction. Methods 100 cases of heart disease patients admitted to our hospital in the past five years were selected as study subjects. Thoracic multi-slice spiral CT scan and color echocardiography were performed on three patients diagnosed with early cardiac dysfunction in the DR heart. After comparative analysis of the patients The results of both examinations. Results The VPW and CTR of patients with pulmonary edema and cardiac dysfunction were (74.79 ± 5.26) mm and (0.73 ± 0.06) mm, respectively. The VPW and CTR of patients without pulmonary edema were (61.56 ± 7.14, ) mm, (0.60 ± 0.08). There was no significant difference in LVEDV, LVESV, LVSV and LVEF between color Doppler ultrasound and HRCT (P> 0.05). There was a good correlation between the two methods = 0.42 ~ 0.88, P <0.05. Conclusion MSCT and echocardiography have no significant difference in the early assessment of left ventricular function, which can be used to diagnose early left ventricular dysfunction and have clinical value in the evaluation of patients with cardiac insufficiency.
