Abstract:
Objective: To analyze the application value of radionuclide myocardial perfusion imaging in the localization and diagnosis for stable angina pectoris in clinical practice. Methods: A total of 70 patients who had been diagnosed with stable angina pectoris (SAP) were enrolled, and all patients underwent ATP-loaded ATP-99Tcm-MIBI (99Tcm-MIBI) myocardial perfusion imaging (MPI) and coronary angiography (CAG) were used to compare the accuracy of MPI imaging in localization and diagnosis for SAP. Results:In the 70 cases of patients with two methods of examination: ①In MPI diagnosis, positive patients were 50 cases, and the positive predictive value of SAP, sensitivity, negative predictive value and specificity were, respectively, 92.0%, 90.2%, 75.0% and 78.9%. There were 45 patients were consistently diagnosed as SAP by the two methods and the total compliance rate was 90.0%. ②in 70 patients, 51 cases were diagnosed as SAP by CAG examination, the positive rate was 72.9%; ③in 50 MPI positive patients, 46 patients were consistent with the results of CAG diagnosis, and the positive rate was 92.0%. The difference between the two methods was statistically significant (x2= 5.72, P<0.05). Conclusion: 99Tcm-MIBI myocardial perfusion imaging can be used as a gatekeeper in patients with stable angina pectoris, and has high application value in the location and diagnosis for stable angina pectoris. The diagnosis and treatment links of stable angina pectoris can save costs and provide a reliable evidencet for clinical practice.
