Objective: To evaluate the value of cardiopulmonary exercise testing in diagnosing coronary atherosclerotic heart diseaseï¼CHD). Methods: A total of 156 patients with suspected CHDï¼The patient's condition is relatively stable, aged 18 to 80 yearsï¼were performed for cardiopulmonary exercise testing, ECG exercise test and coronary angiography. Based on the results of coronary angiography, the sensitivity, specificity and diagnostic value of relevant indicators of cardiopulmonary exercise testing (CPET) parameters (Peak VO2%predãPeak O2 pulse%predãΔVO2/ΔWR) in diagnosing CHD were analyzed by statistical methods based on the results of coronary angiography. Results: Useing the best cut-off point of Peak VO2 ≤69%pred for detecting CHD, the sensitivity was 55.1%, the specificity was 77.0%, and the AUC was 0.698. The sensitivity, specificity and AUC of peak O2 pulse%pred were 50.7%, 72.4% and 0.58 respectively. ΔVO2/ΔWR sensitivity in diagnosing CHD was 44.9%, specificity was 87.4%, AUC was 0.647. The sensitivity of peak O2 pulse%pred and ΔVO2/ΔWR were much higher than the ECG exercise test, the difference was statistically significant (P<0.01). Conclusion: The sensitivity of some indexes of CPET in diagnosing CHD was better than ECG exercise test, the specificity and diagnostic value of the optimal cut-off point are high. CPET has predictive value for the diagnosis of CHD, it can diagnose CHD early and accurately.
