高血压性心脏病是高血压的后期表现,病程进展缓慢,经10年、20年或20年以上才发病。由于高血压,心脏工作负荷增加,引起心脏肥大,以后左心室扩大和衰竭。收缩期血压与心脏重量成正比。心肌细胞直径和长度增加可使心脏重量增加。肥大的心脏主要是冠状动脉扩张,心内膜下血管丛吻合数增加。老年高血压患者的心脏肥大和冠状血
Hypertensive heart disease is a late manifestation of hypertension, the course of slow progress, after 10 years, 20 years or more before onset. Due to high blood pressure, heart workload increases, causing cardiac hypertrophy, later left ventricular enlargement and failure. Systolic blood pressure is proportional to heart weight. Increased cardiomyocyte diameter and length can increase heart weight. Hypertrophic heart is mainly coronary artery dilatation, endocardial vascular bundle anastomosis increased. Cardiac hypertrophy and coronary blood in elderly hypertensive patients
