A cardiopulmonary exercise test provides information regarding appropriate exercise intensity, but there have been few reports on its use in patients over 80 years of age.
Retrospective observational study.
A total of 511 cardiovascular disease patients who performed a cardiopulmonary exercise test from February 2011 to January 2020 were investigated.
Patients were stratified according to age: < 70 years, 70-79 years, and ≥ 80 years, and the results of the cardiopulmonary exercise test up to anaerobic threshold were compared.
Patients in the < 70 age bracket showed higher oxygen consumption, carbon dioxide output, and ventilatory volume and lower ventilation equivalents per oxygen consumption and carbon dioxide output in all time periods. However, there were no significant differences in these parameters or the work rate (70-79 years of age: 41.4 ± 11.7 watts, vs ≥ 80 years: 42.2 ± 10.9 watts, p = 0.95) or oxygen consumption per body weight at anaerobic threshold (12.2 ± 0.2 ml/min/kg, vs 12.1 ± 0.4 ml/min/kg, p = 0.97) between the 70-79 year age bracket and the ≥ 80 year age bracket.
Even for cardiovascular disease patients age ≥ 80 years, a cardiopulmonary exercise test up to anaerobic threshold can supply useful information for guiding cardiac rehabilitation.
心肺运动试验可提供有关适宜运动强度的信息，但有关 80 岁以上患者使用心肺运动试验的报道较少。
回顾性观察研究。
共调查了 511 名 2011 年 2 月至 2020 年 1 月期间进行心肺运动试验的心血管疾病患者。
根据年龄分层患者：<70 岁、70-79 岁和≥80 岁，并比较心肺运动试验直至无氧阈的结果。
<70 岁年龄组患者在所有时间段的耗氧量、二氧化碳产量和通气量较高，而通气量与耗氧量和二氧化碳产量的比值以及工作率较低。然而，这些参数或无氧阈时的氧耗量/体重（70-79 岁：41.4±11.7 瓦，≥80 岁：42.2±10.9 瓦，p=0.95）或无氧阈时的二氧化碳产量（12.2±0.2 ml/min/kg，12.1±0.4 ml/min/kg，p=0.97）在 70-79 岁年龄组和≥80 岁年龄组之间没有显著差异。
即使对于≥80 岁的心血管疾病患者，心肺运动试验直至无氧阈也能提供有用的信息，有助于指导心脏康复。
