Clinical diagnostic value of acoustic cardiography in patients with angina pectoris
To investigate the clinical application value of related parameters of modern acoustic cardiography techniques in the diagnosis of patients with angina pectoris.
Methods
2
A total of 150 patients who were admitted due to angina pectoris and underwent coronary angiography were enrolled, and all patients underwent routine electrocardiography and acoustic cardiography.
Results
2
Among the 150 patients with angina pectoris, 81 had a confirmed diagnosis of coronary artery disease by coronary angiography, and coronary artery disease was excluded in 69 patients after coronary angiography. There were significant differences between the two groups in S4 and ST-T changes on electrocardiography(
P
<
0.05); ST-T changes on electrocardiography had a sensitivity of 54.3% and a specificity of 84.1% in the diagnosis of angina pectoris,while S4 had a sensitivity of 74.1% and a specificity of 82.6%. ST-T changes combined with S4 had a sensitivity of 87.7% and a specificity of 81.2% in the diagnosis of angina pectoris.
Conclusion
2
S4 combined with ST-T changes can improve the diagnostic level of patients with angina pectoris, and therefore, they can be used as important auxiliary indices for the diagnosis and evaluation of patients with angina pectoris.
