中心动脉压及其在航空心血管医学中的应用

Central blood pressure and its application in cardiology in aerospace medicine

中心动脉压能够反映主动脉根部的压力。越来越多证据表明中心动脉压在预测心血管事件方面优于肱动脉压。两者的差异随年龄增大而降低。此外,抗高血压药物对肱动脉压和中心动脉压的影响不同。因此将治疗决策建立在中心动脉压而非肱动脉压的基础上,对青年飞行人员高血压诊断和防治具有重要意义。飞行环境对飞行人员的心血管功能要求比普通人更为严格,传统的血压评估已暴露出诸多不足。因此对于飞行风险的准确评估,中心动脉压监测未来可能发挥重要作用。

Central blood pressure reflects the pressure at the root of the aorta. Growing evidence has demonstrated that central blood pressure is better than brachial pressure in predicting cardiovascular events. The difference between these decreases with older age. In addition, antihypertensive drugs have different effects on brachial and central blood pressure. Therefore, making decisions based on central blood pressure rather than brachial pressure is of great significance for the diagnosis and prevention of hypertension in young aircrew. The cardiovascular requirements in flight environment for aircrew are stricter than that for the general population. Related to increasing training intensity, traditional blood pressure assessment has many shortcomings. Central blood pressure may play an important role in accurate assessment of flight risk in future.
