目的探讨X线及螺旋CT在肺心病合并冠心病诊断中的应用价值。方法对我院60例肺心病患者的临床资料进行回顾性分析。将所选患者分为观察组(肺心病合并冠心病)34例和对照组26例(单纯肺心病),分析其影像学特征。结果 X线胸片示梨形心22例,普大型心18例,肺动脉段突出12例,右下肺动脉干增粗3例。螺旋CT显示双肺纹理紊乱、扭曲,合并冠心病者可见不同程度冠脉病变。其中,观察组诊断率88.2%,对照组26.9%,组间差异具有统计学意义。结论在肺心病合并冠心病的诊断上,螺旋CT较传统的X线检查相比分辨率更高、图像清晰立体,诊断符合率明显提高。 Objective To investigate the value of X-ray and spiral CT in diagnosis of cor pulmonale complicated with cor pulmonale. Methods The clinical data of 60 patients with pulmonary heart disease in our hospital were retrospectively analyzed. Selected patients were divided into observation group (pulmonary heart disease with coronary heart disease) 34 cases and control group 26 cases (simple pulmonary heart disease), analyze its imaging features. Results X-ray showed pear heart in 22 cases, 18 cases of general heart, pulmonary artery segment in 12 cases, right lower pulmonary artery thickening in 3 cases. Spiral CT showed double lung texture disorder, distortion, coronary heart disease in patients with varying degrees of coronary lesions. Among them, the observation group, the diagnosis rate was 88.2%, control group, 26.9%, the difference between groups was statistically significant. Conclusion In the diagnosis of cor pulmonale complicated with coronary heart disease, the spiral CT has higher resolution than the traditional X-ray examination and clear and stereoscopic images, and the diagnostic coincidence rate is obviously improved.
