摘要
目的研究CT冠脉成像(CTA)在慢性心力衰竭诊断中的应用价值。方法回顾性分析2018年1月至2019年7月我院收治的59例慢性心力衰竭患者临床资料,CAG检查显示病因为冠心病者42例,为扩张型心肌病者17例,所有患者均进行CTA检查,对比不同病因慢性心力衰竭患者CTA参数和血管管腔狭窄程度,评估CTA在慢性心力衰竭病因诊断中的应用价值。结果冠心病引起的慢性心力衰竭患者左心室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、二尖瓣口舒张早期血流速度峰值(E)/舒张晚期血流速度峰值(A)(E/A)水平均低于扩张型心肌病引起的慢性心力衰竭患者(P<0.05)。冠心病引起的慢性心力衰竭患者CTA检查血管管腔狭窄程度高于扩张型心肌病引起的慢性心力衰竭患者(P<0.05)。CTA对慢性心力衰竭病因的诊断结果与CAG诊断结果一致性为Kappa值=0.840,一致性高。结论CTA可有效鉴别诊断慢性心力衰竭病因,具有较好临床应用价值。
Objective To study the application value of coronary CT angiography(CTA)in the diagnosis of chronic heart failure.Methods The clinical data of 59 patients with chronic heart failure admitted to the hospital between January 2018 and July 2019 were retrospectively analyzed.CAG examination showed 42 patients with coronary heart disease and 17 patients with dilated cardiomyopathy.All patients completed CTA.CTA parameters and degree of vascular lumen stenosis in patients with chronic heart failure of different causes were compared.The application value of CTA in the diagnosis of the cause of chronic heart failure was evaluated.Results The left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and the early mitral orifice diastolic blood flow velocity peak(E)/advanced diastolic blood flow velocity peak(A)(E/A)ratio in patients with chronic heart failure caused by coronary heart disease were lower than those caused by dilated cardiomyopathy(P<0.05).CTA examination showed that vascular lumen stenosis was severer in patients with chronic heart failure caused by coronary heart disease than those caused by dilated cardiomyopathy(P<0.05).The diagnosis results of CTA for the cause of chronic heart failure were highly consistent with those of CAG,Kappa value=0.840.Conclusion CTA can effectively diagnose the cause of chronic heart failure and has good clinical application value.
