摘　　要：目的 探讨影响高血压飞行人员心肺储备能力的主要因素. 方法 根据《中国高血压防治指南2010》选择高血压和非高血压飞行人员各17例,进行心肺运动试验,测量并比较两组的每千克体重峰值摄氧量（peak oxygen uptake per kilogram,VO2peak/kg）、无氧阈（anaerobic threshold,AT）时的摄氧量（oxygen uptate per kilogram at AT,VO2/kg@AT）、峰值氧脉搏（peak oxygen pulse,O2 pulsepeak）、血压、心率、运动时间等指标. 结果 高血压组与正常组的VO2peak、VO2@AT、O2 pulsepeak差异无统计学意义（P＞0.05）;两组的运动峰值收缩压、舒张压、峰值心率、运动前后收缩压变化值、心率变化值、运动后6 min血压、运动时间比较差异有统计学意义（t=2.622～4.945,P＜0.01或P＜0.05）. 结论 高血压飞行人员运动耐量的气体代谢指标变化不明显,血压的运动反应更敏感.在飞行人员高血压病的诊治、鉴定和随访中,运动血压应作为诊室血压和动态血压的补充.Objective To investigate the main factors influencing cardiac pulmonary reserve of hypertensive aircrews.Methods The aircrews were divided into hypertension group （n=17） and normal group （n=17） by the diagnosis of hypertension that defined in Chinese Hypertension Guideline 2010.Such parameters as peak oxygen uptake per kilogram （VO2peak/kg）,VO2/kg at anaerobic threshold （VO2/kg@AT）,peak oxygen pulse （O2 pulsepeak）,blood pressure （BP）,heart rate （HR）,exercise time in cardiopulmonary exercise test （CPET） were recorded in cardiopulmonary exercise and analyzed.Results There were no differences in VO2peak,VO2@AT and VO2peak between two groups （P〉0.05）.Significant differences existed in peak SBP,DBP and HR,△SBP,△HR,BP levels at 6 minutes after exercise,exercise time between groups （t=2.622-4.945,P〈0.01or 〈0.05）.Conclusions BP responses are more sensitive than gaseous metabolism indexes during hypertensive aircrews＇ CPET.Exercise BP would be the supplement of conventional BP and ambulatory BP monitoring in the diagnosis,treatment,medical assessment and follow-up of hypertensive aircrews.
