高血压是全世界患病率最高的慢性病之一,也是心血管病的首要危险因素。据统计,高血压患者的血压每增高20/10mm Hg(1 mm Hg=0.133kPa),心血管病死亡率将成倍增加,在我国每年300万例心血管病死亡中至少一半与高血压相关[1]。最大限度地降低心血管并发症发生与死亡的总体危险是高血压的主 Hypertension is one of the most prevalent chronic diseases in the world and is also the primary risk factor for cardiovascular disease. According to statistics, cardiovascular disease mortality will double by 20 / 10mm Hg (1 mm Hg = 0.133kPa) in patients with hypertension. In China, at least half of the 3 million cardiovascular deaths each year are associated with hypertension [1]. The overall risk of minimizing the occurrence and death of cardiovascular complications is high blood pressure
