Clinical value of cardiopulmonary exercise test combined with Holter monitor in the diagnosis of coronary heart disease
Objective To explore the clinical value of cardiopulmonary exercise test combined with Holter monitor in the diagnosis of coronary heart disease. Methods A total of 130 patients with suspected coronary heart disease were selected for observation. They were subjected to cardiopulmonary exercise test,Holter monitor test,and coronary angiography. The results of coronary angiography was used as the gold standard to compare the diagnostic efficacy of dynamic electrocardiography and Holter monitor alone and in combination. Results Among 130 patients with suspected coronary heart disease,coronary angiography diagnosed 95 positive cases and 35 negative cases;Holter monitor diagnosed 80 true positive cases and 24 true negative cases;cardiopulmonary exercise test diagnosed 82 true positive cases and 125 true negative cases;cardiopulmonary exercise test combined with Holter monitor diagnosed 90 true positive cases and 32 true negative cases. The sensitivity and specificity of cardiopulmonary exercise test combined with Holter monitor were 94.74％ and 91.43％;the sensitivity and specificity of cardiopulmonary exercise test were 86.32％ and 71.43％;the sensitivity and specificity of Holter monitor were 84.21％ and 68.57％. The sensitivity and specificity of cardiopulmonary exercise test combined with Holter monitor were higher than that of cardiopulmonary exercise test or Holter electrocardiogram alone,and the difference was statistically significant (P<0.05). There was no significant difference in the comparison of sensitivity and specificity between cardiopulmonary exercise test and Holter monitor (P>0.05). Conclusion The combined of cardiopulmonary exercise test and Holter monitor for patients with suspected coronary heart disease has a good effect,which can improve the sensitivity of disease diagnosis,provide a basis for patient treatment and ultimately provide diagnostic value for disease diagnosis.
