动脉顺应性及其影响因素

动脉顺应性又称动脉弹性，反映血管内皮功能。已成为预测心血管疾病的重要危险因素。无创测量动脉弹性的方法在临床上已有一定程度的应用。各种方法具有其各自适用范围及局限性。多种干预手段可以影响动脉弹性。合理测量及维持正常的动脉弹性可延缓多种心血管疾病的发生及发展。

Arterial compliance and influencing factors

Arterial compliance means arterial elasticity. It is now recognized, that, in addition to blood pressure, other physical parameters of the circulation contribute to and/or serve as markers of vascular disease.Arterial elasticity has emerged as one such important parameter and is defined mathematically as the change in volume of a blood vessel for any given change in blood pressure for each heart beat. Noninvasive methods of arterial elasticity are far more popular for use due to their ease, relative safety to the patient. Patients with reduced arterial elasticity are believed to be at higher risk of cardiovascular conditions including arteriosclerosis and of having risk factors including chronic tobacco use, hyperlipidemia, diabetes and/or hypertension.
