Analysis of diagnostic value of echocardiography combined with electrocardiogram on the severity of coronary heart disease with heart failure
Objective To analyze the diagnostic value of echocardiography combined with electrocardiogram on the severity of coronary heart disease with heart failure.Methods A total of 120 patients with coronary heart disease and heart failure were included in this study.All the patients were detected by echocardiography and electrocardiogram.The New York Heart Association(NYHA)cardiac function grading was analyzed.The echocardiography indexes and electrocardiogram indexes of patients with different severity of disease were compared,as well as the diagnostic accuracy of different detection methods for coronary heart disease with heart failure.Results Among the 120 patients,45 patients were in NYHA cardiac function grade Ⅱ,accounting for 37.50%,42 patients in grade Ⅲ,accounting for 35.00%,and 33 patients in grade Ⅳ,accounting for 27.50%.In NYHA grade Ⅳ patients,the left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),and left atrium(LA)were higher than those in grade Ⅲ and grade Ⅱ patients;the left ventricular ejection fraction(LVEF),and ratio of peak mitral flow velocity in early diastole to peak mitral flow velocity in late diastole(E/A)were lower than those in grade Ⅲ and grade Ⅱ patients;there was statistical differences(P<0.05).LVESD,LVEDD and LA in NYHA grade Ⅲ patients were higher than those in gradeⅡ patients,and LVEF and E/A were lower than those in grade Ⅱ patients.There was statistical difference(P<0.05).The QRS voltage of NYHA grade Ⅳ,Ⅲ and Ⅱ patients were(12.02±0.89),(13.34±0.71)and(14.87±0.65)mV,the QRS duration were(133.75±15.67),(125.47±17.54)and(112.86±15.54)ms,and the QTc interval were(472.65±23.65),(441.69±22.87)and(424.66±20.54)ms.The QRS voltage of NYHA grade Ⅳ and Ⅲ patients were lower than those of grade Ⅱ patients,and the QRS duration and QTc interval were longer than those of gradeⅡ patients.There was statistical difference(P<0.05).The QRS voltage of NYHA grade Ⅳ patients was lower than that of grade Ⅲ patients,and the QRS duration and QTc interval were longer than thoseof grade Ⅲ patients.There was statistical difference(P<0.05).The diagnostic accuracy of echocardiography+electrocardiogram(99.17%)was higher than that of echocardiography(96.67%)and electrocardiogram(91.67%),and there was statistical difference(P<0.05).Conclusion During the clinical diagnosis of the disease severity of patients with coronary heart disease and heart failure,the combination of echocardiography and electrocardiogram has higher diagnostic value,and is more accurate than single detection.It can timely grasp the development of the disease,and take corresponding measures to intervene in combination with the detection results to save the life and health of patients,and is worthy of widespread clinical application.
