中心动脉压与周围动脉压的关系研究

Research on the relationship between central aortic pressure and peripheral arterial pressure

目的 :了解中心动脉压与周围动脉压的关系。方法 :对 65例行左心导管术者 ,用导管直接测定升主动脉、胸主动脉及股动脉压 ;同时用袖带汞柱血压计测定右上臂肱动脉压。结果 :从升主动脉、胸主动脉到股动脉 ,收缩压逐渐升高 ,非高血压组 40岁以下者有显著性差异。升主动脉收缩压明显高于肱动脉压 ,高血压组及非高血压组 40岁以上者有显著性差异 ;二者差值与升主动脉脉压显著正相关。结论 :血管内股动脉收缩压高于升主动脉压 ;升主动脉收缩压高于袖套法测定的肱动脉压 ,二者差异与动脉硬化有关。

Objective : To evaluate the relationship between central aortic pressure and peripheral arterial pressure .Methods : Left-heart cannulation was used in 65 patients ,and the ascending aorta, thoracic aorta and femoral artery pressures were measured with catheters. In the meantime, the right brachial pressure was measured by the cuff method of auscultation . Results: The systolic pressure was increasing from the ascending aorta, thoracic aorta to femoral artery,while non-hypertensive patients under 40 years of age showed significant difference. The ascending aortic systolic pressure was higher than the brachial pressure. This is more significant in hypertensive patients and non-hypertensive patients over 40 years of age. Their difference was positively related to the ascending aortic pressure. Conclusion : Femoral systolic pressure is higher than ascending aortic pressure. Central systolic pressure is higher than brachial systolic pressure , Their difference is related to arteriosclerosis.
