摘要
目的探讨心脏彩色多普勒超声对高血压性心脏病(HHD)患者病情程度的评估价值。方法62例HHD患者,均行心脏彩色多普勒超声检查和心电图检查。比较两种检查方式对心脏异常的检出情况、心脏指标的检查结果及不同病情程度患者心脏指标的检查结果。结果心脏彩色多普勒超声检查对左心室肥厚、左心室扩大、左心房增大、主动脉扩张、主动脉弹性减退的检出率分别为75.81%、41.94%、50.00%、59.68%、12.90%,均高于心电图检查的38.71%、14.52%、11.29%、0、0,差异有统计学意义(P<0.05)。心脏彩色多普勒超声检查中左心房内径(3.74±0.57)cm、左心房与主动脉内径比值(1.23±0.21)均大于心电图检查的(2.59±0.41)cm、(0.48±0.06),差异有统计学意义(P<0.05);两种检查方式中二尖瓣舒张早期最大速度与心房收缩期间的最大速度(E/A值)、左心室射血分数比较,差异无统计学意义(P>0.05)。不同心功能分级患者左心房内径、左心房与主动脉内径比值比较,差异有统计学意义(P<0.05);Ⅱ、Ⅲ级患者左心房内径、左心房与主动脉内径比值大于Ⅰ级患者,差异有统计学意义(P<0.05);Ⅲ级患者左心房内径、左心房与主动脉内径比值大于Ⅱ级患者,差异有统计学意义(P<0.05)。结论心脏彩色多普勒超声能够清晰显示HHD患者心室、心房等相关切面,准确诊断病变部位,有利于检出心脏异常情况,评估病情严重程度。
Objective To discuss the evaluation value of color Doppler echocardiography in assessing disease severity of patients with hypertensive heart disease(HHD).Methods 62 HHD patients were selected,and all underwent color Doppler ultrasonography and electrocardiogram examination.The detection of cardiac abnormalities,the results of cardiac indexes and the results of cardiac indexes in patients with different disease severity were compared between the two methods.Results The detection rates of left ventricular hypertrophy,left ventricular enlargement,left atrial enlargement,aortic dilatation and impaired aortic elasticity by color Doppler echocardiography were 75.81%,41.94%,50.00%,59.68% and 12.90%,which were higher than those of 38.71%,14.52%,11.29%,0 and 0 by electrocardiogram,and the differences were statistically significant(P<0.05).The left atrial diameter of(3.74±0.57)cm and the ratio of left atrial to aortic diameter of(1.23±0.21)by color Doppler echocardiography were higher than those of(2.59±0.41)cm and(0.48±0.06)by electrocardiogram,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the ratio of early transmitral flow velocity to later transmitral flow velocity(E/A value)and left ventricular ejection fraction between the two methods(P>0.05).The difference of left atrial diameter and the ratio of left atrial to aortic diameter in patients with different cardiac function grading was statistically significant(P<0.05).The left atrial diameter and ratio of left atrial to aortic diameter in grade Ⅱ and Ⅲ patients were higher than that in grade Ⅰ patients,and the difference was statistically significant(P<0.05).The left atrial diameter and ratio of left atrial to aortic diameter in grade Ⅲ patients was higher than that in grade Ⅱ patients,and the difference was statistically significant(P<0.05).Conclusion Color Doppler echocardiography can clearly display the relevant sections of ventricle and atrium in HHD patients,accurately diagnose the lesion site,and facilitate the detection of cardiac abnormalities and the evaluation of the severity of the disease.
