Diagnostic value of cardiopulmonary exercise test for coronary heart disease / 中华全科医师杂志

Cardiopulmonary exercise test and electrocardiogram exercise test were performed in 68 patients with suspected coronary artery disease,the diagnostic value of two tests was compared with coronary angiography results as the gold standard.The results show that the sensitivity,specificity,positive predictive value and negative predictive value of electrocardiogram exercise test for coronary heart disease were 51.28％,68.97％,68.97％ and 51.28％ respectively; those for ratio of O2 pulse peak in cardiopulmonary exercise test were 51.28％,75.86％,74.07％ and 53.66％ respectively.It suggests that the results of cardiopulmonary exercise test may have the same value as electrocardiogram exercise test in diagnosis of coronary artery disease.
