Abstract：
Several reports have shown the impact of COVID-19 history on exercise capacity. This study compared the blood pressure (BP) response and oxygen pulse (O2 pulse) characteristics in normotensive patients with and without a history of COVID-19 during the cardiopulmonary exercise test (CPET) and post-exercise recovery. This cross-sectional study involved 130 healthy Caucasian adult volunteers (71 participants with a history of COVID-19). All patients underwent the CPET with blood pressure measurements during exercise and post-exercise recovery. The post-COVID group had significantly higher systolic, diastolic, and mean blood pressure after 9 min of recovery and achieved a significantly lower max O2 pulse (2.02 mL/beat on average) than the controls. It should be noted that the COVID group tended to have higher blood pressure values in all steps, with no differences in heart rate, pulse pressure, and saturation at any step. The COVID-19 outbreak was associated with a higher blood pressure response, significantly, in post-exercise recovery, a lower maximum O2 pulse, and a lower maximum load achievement. Future studies are needed to determine if these abnormalities during the CPET and the blood pressure variation have prognostic value.
摘要：
几份报告显示了COVID-19历史对运动能力的影响。这项研究比较了有和没有COVID-19病史的正常血压患者在心肺运动试验（CPET）和运动后恢复期间的血压（BP）反应和氧脉冲（O2脉冲）特征。这项横断面研究涉及130名健康的白人成年志愿者（71名具有COVID-19病史的参与者）。所有患者在运动和运动后恢复期间均接受了CPET的血压测量。后COVID组收缩压明显升高，舒张压,恢复9分钟后的平均血压和最大O2脉冲（平均2.02mL/搏动）显着低于对照组。应该注意的是，COVID组在所有步骤中都倾向于具有较高的血压值，心率没有差异，脉压,在任何步骤饱和。COVID-19的爆发与较高的血压反应有关，显著,在运动后恢复中，较低的最大O2脉冲，和较低的最大负载成就。需要进一步的研究来确定CPET期间的这些异常和血压变化是否具有预后价值。
