OBJECTIVE
To assess the validity of the Ekblom-Bak cycle ergometer test in patients with cardiovascular disease admitted to cardiac rehabilitation.
METHODS
Estimated peak oxygen consumption from the Ekblom-Bak test was compared with directly measured peak oxygen consumption from a treadmill cardiopulmonary exercise test. Patients completed the cardiopulmonary exercise test first, followed by the Ekblom-Bak test after 24 h rest. Pearson's correlation coefficient (r) was used to establish the correlation between estimated and measured peak oxygen consumption, and Bland-Altman plots with limits of agreement were used to determine the bias between the 2 tests.
RESULTS
Twenty-six patients were included in the final analysis. The Ekblom-Bak test significantly overestimated peak oxygen consumption. Agreement between estimated and measured peak oxygen consumption was: bias = 4.3 mL/kg/min (limits of agreement: -4.0-12.6 mL/kg/min).
CONCLUSION
The Ekblom-Bak test overestimated peak oxygen consumption to such an extent that it cannot accurately assess cardiorespiratory fitness in patients with cardiovascular disease. Thus, the cardiopulmonary exercise test remains the test of choice.
目的
评估 Ekblom-Bak 功率自行车测试在心血管疾病患者心脏康复中的有效性。
方法
将 Ekblom-Bak 测试中估计的峰值耗氧量与跑步机心肺运动试验直接测量的峰值耗氧量进行比较。患者首先完成心肺运动试验，然后在 24 小时休息后进行 Ekblom-Bak 测试。使用 Pearson 相关系数 (r) 建立估计和实测峰值耗氧量之间的相关性，并使用具有一致性界限的 Bland-Altman 图确定两种测试之间的偏差。
结果
最终分析纳入 26 例患者。Ekblom-Bak 测试显著高估了峰值耗氧量。估计和实测峰值耗氧量之间的一致性为：偏差=4.3mL/kg/min（一致性界限：-4.0-12.6mL/kg/min）。
结论
Ekblom-Bak 测试高估了峰值耗氧量，以至于无法准确评估心血管疾病患者的心肺适应能力。因此，心肺运动试验仍然是首选的测试方法。
