应用心脏B超诊断冠心病节段性室壁运动异常的临床研究

Clinical Study on Cardiac B-Ultrasound in the Diagnosis of Regional Wall Motion Abnormality in Coronary Heart Disease

目的探讨心脏B超诊断冠心病节段性室壁运动异常的临床应用价值。方法选取我院2015年12月至2016年12月收治的168例冠心病节段性室壁运动异常患者,均行冠状动脉造影检查,然后实施心脏B超检查,根据其冠状动脉造影结果分析其心脏B超的临床应用价值。结果心脏B超检查左房内径、左室舒末径、右室流出道、主动脉内径及右房右室内径等准确率与冠状动脉造影检查比较,差异均无统计学意义(P>0.05);心脏B超检查的总体准确率为88.7%,低于冠状动脉造影的100.0%,差异有统计学意义(P<0.05)。结论采用心脏B超诊断冠心病节段性室壁运动异常,灵敏度较高,能够有效判断病情变化,值得临床推广应用。

Objective To explore the clinical application value of cardiac B-ultrasond in the diagnosis of regional wall motion abnormality in coronary heart disease. Methods 168 cases of patients with regional wall motion abnormality of coronary heart disease admitted to our hospital from December 2015 to December 2016 were selected and given coronary angiography and then cardiac B-ultrasond. The clinical application value of B-ultrasond was analyzed according to the results of coronary angiography. Results No statistical difference was found in the accuracy of left atrial diameter, left ventricular end-diastolic diameter, right ventricular outflow tract, aortic diameter, right atrial and right ventricular diameter between B-ultrasond and coronary angiography （P 〉0.05）. The total accuracy of B-ultrasound was 88.7%, lower than 100.0% of coronary angiography, with statistical difference （P 〈0.05）. Conclusions Cardiac B-ultrasond in the diagnosis of regional wall motion abnormality in coronary heart disease has higher sensitivity and can effectively determine the condition changes, which is worthy of clinical promotion and application.
