OBJECTIVE: To evaluate the diagnostic efficacy of Qisexingtai hand diagnostic method in the diagnosis of coronary artery disease (CAD). METHODS: This was an investigator-initiated, prospective, multi-center, cross-sectional study. All the participants from three hospitals in China had been diagnosed by both Qisexingtai hand diagnostic method and coronary angiography. We compared the two diagnostic methods to calculate the sensitivity, the specificity, the omission diagnostic rate, the mistaken diagnostic rate and accuracy in order to evaluate the diagnostic efficacy of Qisexingtai hand diagnostic method for CAD. RESULTS: A total of 326 subjects were enrolled, diagnosed by both Qisexingtai hand diagnostic method and coronary angiography. As a result, there were 166 positive cases according to Qisexingtai hand diagnostic method, and 131 positive cases according to coronary angiography. Compared with the results of coronary angiography, the sensitivity of Qisexingtai hand dia-gnostic method was 80.2%, the specificity was 68.7%, the omission diagnostic rate was 19.8%, the mistaken diagnostic rate was 31.3%, and the accuracy was 73.3%. Area under the receiver operating characteristic curve was estimated as 0.735 for all, and 0.718, 0.735, 0.783 for the three sub-centers.CONCLUSION: Qisexingtai hand diagnostic method with high accuracy and sensitivity has certain application value in the diagnosis of CAD.(c) 2022 JTCM.
