Abstract：Objective To explore the application value of real-time myocardial contrast echocardiography（MCE）combined with four-dimensional strain technology（4D-SI）in the diagnosis of coronary heart disease（CHD）.Methods 80 patients with highly suspected CHD admitted to our hospital were selected as the subjects of theresearch group（71 patients were finally diagnosed,and were divided into 27 mild cases,25 moderate cases and 19 severe cases）.And 30 healthy volunteers during the same period were selected as the control group.All personnel underwent MCE and 4D-SI examinations to evaluate the diagnostic efficacy.Compare the myocardial blood supply and the peak strain of myocardial systole between the groups.Results The diagnostic sensitivity of MCE combined with 4D-SI was 91.55%,the specificity was 66.66%,and the accuracy was 88.75%,which was higher than that of MCE combined with automatic imaging technology（78.87%,44.44%,and 75.00%）.Among them,the difference in sensitivity and accuracy was statistically significant（P<0.05）.Compared with the control group,4D-GLPS,4D-GCPS,4D-GAPS and 4D-GRPS were significantly reduced.In patients with mild stenosis,only 4D-GLPS and 4D-GAPS were significantly reduced（P<0.05）.Conclusion MCE combined with 4D-SI can more accurately and intuitively understand the myocardial function of CHD patients,assist clinical evaluation,and have a higher diagnostic efficiency.Among them,4D-GLPS and 4D-GAPS can also reflect the early pathological changes of CHD,which is conducive to its early diagnosis.
