Analysis of the Effectiveness of Cardiac Ultrasound in Diagnosing Coronary Heart Disease and Evaluating Wall Motion Abnormalities in Patients
Objective To explore the effectiveness of cardiac ultrasound in diagnosing coronary heart disease(CHD)and evaluating wall motion abnormalities in patients.Methods One hundred patients with suspected CHD treated at Jinshui District General Hospital from March 2021 to June 2023 were selected.Using coronary angiography as the"gold standard,"patients were divided into the CHD group(n=80)and the non-CHD group(n=20).All patients underwent cardiac ultrasound examination.Cardiac ultrasound indicators[left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV),stroke volume(SV)]were compared between the CHD group and the non-CHD group.Sensitivity,specificity,and Youden index were used to analyze the diagnostic efficacy of cardiac ultrasound and its effectiveness in diagnosing segmental wall motion abnormalities in CHD patients.Results The LVESV in the CHD group was higher than that in the non-CHD group,while the LVEF,LVEDV,and SV were lower than those in the non-CHD group,with statistically significant differences(P＜0.05).Using coronary angiography as the gold standard,the accuracy,sensitivity,specificity,and Youden index of cardiac ultrasound were 97.00%,97.50%,95.00%,and 0.815,respectively.Coronary angiography showed that 80 patients had varying degrees of segmental wall motion abnormalities,while cardiac ultrasound detected segmental wall motion abnormalities in 75 patients,with a detection rate of 93.75%.Conclusion Cardiac ultrasound examination has certain value in diagnosing CHD patients and can effectively evaluate wall motion abnormalities.
