“…Therefore, statistics based on those studies are unlikely to provide a robust estimate for the CPX variables of interest in those study populations. The anthropometric features of our population sample fit within the reported standard ranges for East Asian populations, which suggests that the study sample reported herein is similar to normal/healthy adult populations across East Asian countries [8,15,[27][28][29][30].…”

Background: Reference values of cardiopulmonary exercise testing (CPX) vary with race/ethnicity. Chinese Americans are the fastest-growing racial/ethnic group in the United States. However, there is limited information about the reference values of cardiopulmonary exercise testing (CPX) variables in the Chinese population. Methods: As part of the Xiangya Hospital Exercise Testing project (the X-ET project), this cross-sectional study screened 20,696 consecutive CPXs performed by 17,802 unique individuals at

“…Anthropometric features such as weight and height of the Caucasian and Asian population are different. For example, height, weight and BMI of subjects in an Asian population 14 16 19 20 21 22 23 were similar to those of the present study, but lower than those of primarily Caucasians. 12 13 18 As above, the predicted VO 2 max using Yaoshan equation using the Asian population had good agreement with our study.…”

Background Maximal oxygen uptake (VO 2 max) is a useful index to assess exercise capacity. However, there is no reference value for Koreans. This study aimed to compare actual VO 2 max and predicted VO 2 max using exercise capacity equations in Korean subjects. Methods This retrospective study enrolled 383 patients who underwent cardiopulmonary exercise test (CPET) with incremental maximal cycle ergometer test at Asan Medical Center from January 2020 to May 2021. Stage 1 and 2 lung cancer patients with normal lung function and healthy persons of 50 subjects who had maximal CPET were analyzed. Results The subjects were aged 65 ± 13 years and predominantly male (74%). CPET results were as follows: absolute VO 2 max, 1.2 ± 0.3 L/min; body weight referenced VO 2 max, 20 ± 3.9 mL/kg/min; peak work rate, 94 ± 24 watts; peak heart rate, 142 ± 21 bpm; peak O 2 pulse, 10 ± 3 mL/beat; minute ventilation, 59 ± 14 L/min; peak respiratory rate, 34 ± 6 breaths per minute; and peak breathing reserve, 41 ± 18%. There was significant discordance between the measured and predicted absolute VO 2 max using the Jones, Hansen, and Wasserman prediction equations developed for Caucasian population ( P < 0.001). Agreement using Bland-Altman test between true and predicted absolute VO 2 max was the best in Chinese equation (−0.03, 2SD = 0.55) compared to Jones (0.42, 2SD = 1.07), Hansen (0.44, 2SD = 0.86), and Wasserman (0.42, 2SD = 0.86) equations. Conclusion The reference value and prediction equation from studies including primarily Caucasians may not be appropriate for Koreans. Since the mean difference is the lowest in Chinese equation, the Chinese equation might be used for the Korean adult population.

“…In has been known that the prevalence of obstructive CAD was lower in Asian than in Western, especially in women. 24) 25) 26) Moreover compared to western women, Asian women presented more atypical symptoms in patients with stable angina. 27) Because clinical characteristics and risk factors of CAD were different between Asian and Western female patients, the accuracy of noninvasive diagnostic tests and its clinical applications need to be evaluated in Korean female patients.…”

BackgroundExercise-stress electrocardiography (ECG) is initially recommended for the diagnosis of coronary artery disease. But its value has been questioned in women because of suboptimal diagnostic accuracy. Stress echocardiography had been reported to have comparable test accuracy in women. But the data comparing the diagnostic accuracy of exercise-stress ECG and stress echocardiography directly are few. The aim of the study was to compare the diagnostic accuracy of exercise-stress ECG and dobutamine stress echocardiography (DSE) in Korean women.Methods202 consecutive female patients who presented with chest pain in outpatient clinic, and who underwent treadmill exercise test (TET), DSE and coronary angiography were included for the study. The diagnostic accuracy TET and DSE were calculated by the definition of > 50% or > 75% coronary artery stenosis (CAS).ResultsThe sensitivity and specificity were higher with DSE (70.4, 94.6%) than TET (53.7, 73.6%) for detection of > 50% CAS. The higher accuracy of DSE was maintained after exclusion of the patients who could not achieve over 85% age predicted heart rate before ischemia induction. DSE also showed greater diagnostic accuracy than TET by > 75% CAS criteria, and in subsets of patient with intermediate pretest probability.ConclusionIn the diagnosis of CAS, DSE showed higher accuracy than TET in female patients who presented with chest pain. As well as the test accuracy, adequate stress was more feasible with DSE than TET. These finding suggests DSE may be used as the first-line diagnostic tool in the detection of CAS in women with chest pain.
