Abstract：ObjectiveTo investigate the diagnostic value of heart rate recovery(HRR) after treadmill exercise test(TET) in patients with coronary heart disease(CHD). MethodsFortytwo patients were selected in our study who had been performed TET. According to results of coronary angiography, they were divided into CHD group(23 cases) and nonCHD group(19 cases). Comparative analysis of age, gender, smoking history, resting heart rate, peak exercise heart rate, history of hypertension, diabetes or hyperlipidemia, and HRR values 1, 2, 3, 4, 5, 6 and 7 min after TET were carried out between the two groups. HRR value 1 and 2 min after exercise were considered as a diagnostic criteria for CHD. The sensitivity, specificity and diagnostic coincidence rate were compared between HRR indexes and the positive indexes in the traditional STsegmentdepression method. ResultsIn the CHD group, HRR value 1 min after exercise was significantly lower than that in the nonCHD group with statistically significant difference while the rapid recovery period was longer. In the diagnosis of CHD, the sensitivity, specificity and diagnostic coincidence rate of HRR 1 min after exercise were all higher than those of positive indexes in the traditional STsegmentdepression method.ConclusionHRR 1 min after TET could be served as an effective index for screening and diagnosing CHD.
