女性高血压患者心肺运动试验中血压经时变化研究

Time-dependent Changes of Blood Pressure in Cardiopulmonary Exercise Test for Females with Hypertension

目的探讨女性高血压患者心肺运动试验中,随运动强度增加血压的经时变化及其临床意义。方法选取本院2018年8月至2019年8月心肺运动试验排除心肌缺血,且未服用β受体阻滞剂及非二氢吡啶类钙离子拮抗剂的1级、2级高血压女性患者64例(高血压组),以及同期心肺运动试验排除心肌缺血的年龄匹配的健康女性86例(非高血压组),比较两组心肺运动试验中随运动强度增加血压的经时变化。结果高血压组运动中静息3 min时血压、无氧阈值时血压和峰值血压均显著高于非高血压组(Z>3.306,P<0.001)。两组峰值摄氧量无显著性差异(Z=1.549,P>0.05)。结论1级和2级高血压患者血压对运动的反应容易过度升高,在日常体育运动训练及运动康复中应关注血压的变化。

Objective To explore the time-dependent changes of blood pressure with the increase of exercise intensity and its clinical significance in Cardiopulmonary Exercise Test for female patients with hypertension.Methods From August,2018 to August,2019,64 patients(hypertension group)who did not takeβ-receptor blockers and dihydropyridine calcium antagonists were selected from grade 1 and grade 2 hypertension women excluding myocardial ischemia with Cardiopulmonary Exercise Test.And 86 healthy women(non-hypertension group)excluding myocardial ischemia from the same period of Cardiopulmonary Exercise Test were selected as the controls for retrospective analysis.The time-dependent changes of blood pressure with the increase of exercise intensity were compared between two groups.Results The blood pressures at resting for three minutes,anaerobic threshold and peak were significantly higher in the hypertension group than in the non-hypertension group(Z>3.306,P<0.001).There was no significant difference in peak oxygen uptake between two groups(Z=1.549,P>0.05).Conclusion The blood pressure of the patients with grade 1 and grade 2 hypertension is prone to over elevation,who should pay more attention on blood pressure in sports and rehabilitation.
