老年高血压患者往往以收缩压明显增高及脉压差增大为特征,与其动脉血管舒张功能减退有关。动脉血管和心肌组织中的胶原蛋白随增龄或在某些病理状态下(如糖尿病)发生缓慢而持续性的交联化(cross-linking)[1],导致与年龄相关的或病理性的血管弹性和心室顺应性减退[2]。老年高血压
Elderly patients with hypertension often systolic pressure was significantly increased and increased pulse pressure is characterized by increased, and its decline in arterial vasodilation related. Collagen in arteries and myocardium slowly or continuously cross-links with aging or in certain pathological conditions such as diabetes [1], leading to age-related or pathological Vascular flexibility and ventricular compliance decreased [2]. Elderly high blood pressure
