脉压是心脑血管意外的独立危险因素。动脉僵硬性增加会引起动脉扩张性降低,导致收缩压水平升高。而舒张时动脉的弹性回缩差,舒张压水平降低,从而脉压增大。脉压差大,患痴呆的危险性升高,脉压可作为预测卒中事件的一个重要指标。脉压和左心室肥厚、慢性心力衰竭、冠心病都有相关性。 Pulse pressure is an independent risk factor for cardiovascular and cerebrovascular accidents. Arterial stiffness increases arterial distensibility will lead to reduced, leading to elevated systolic blood pressure. Diastolic arterial elastic contraction is poor, diastolic blood pressure levels lower, resulting in increased pulse pressure. Pulse pressure is large, the risk of dementia increased, pulse pressure can be used as an important indicator of stroke events. Pulse pressure and left ventricular hypertrophy, chronic heart failure, coronary heart disease are related.
