摘　　要：目的探讨高分辨率CT诊断早期左心功能不全的临床价值。方法选择近五年收治的心脏疾病患者100例作为研究对象,对患者分别采取DR心脏三位片、胸部CT平扫加HRCT、彩色超声心动图检查,对比分析患者检查结果,并对患者分别进行3、6、9、12、15和18个月追踪复查。结果肺水肿患者心功能不全时血管蒂宽度(VPW)、心胸比例(CTR)值分别为(74.79±5.26)mm和(0.73±0.06),无肺水肿患者分别为(61.56±7.14)mm和(0.60±0.08);彩超与HRCT检查测得的LVEDV、LVESV、LVSV、LVEF结果无统计学差异(P>0.05),两种检查方法的左心功能指标相关性好,r=0.42～0.88(P<0.05)。结论高分辨率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 clinical value of the high-resolution CT in the diagnosis in early left ventricular dysfunction. Methods 100 cases of heart disease were admitted in the research object in the past five years, and thesepatients were detected by the DR heart three piece, chest CT scan ＋ of HRCT, and color echocardiography. Patients were fellow up for 3, 6, 9, 12, 15 and 18 months. Results Vascular pedicle width （VPW） and eardiothoracic ratio （CTR） of patients of pulmonary edema with heart dysfunction were （74. 79士5.26） mm and （0.73士0. 06） respectively, in non-pulmonary edema patients, were （61. 56士7.14） mm and （0. 60士0. 08） respectively. The results of Color Doppler and HRCT examinations measured in the LVEDV and LVESV was no significant difference （P〉0.05）, and the correlation of left ventricular function indices of the two methods is good, r =0.42～0. 88, P〈0. 05. Conclusion There was no significant difference between high-resolution CT and ultrasound echocardiography map to diagnose early left ventricular function, so high-resolution CT could be used to diagnose early left ventricular function.
