在西方国家,粥样硬化性血管疾患是首要的死亡原因,而高血压则是其重要的前驱之一。在美国,约半数死亡的是由于涉及冠状、脑及周围血循环的动脉粥样硬化性病变所造成,其中冠心病占死亡率的2/3。美国成年人中15～20％有高血压,5％肯定或疑有冠心病,估计约50％的男性冠心病患者和75％的女性冠心病患者并有高血压。从1955年到1965年,高血压性心脏病的总死亡率降低了46％,而同一时期冠状动脉硬化性心脏病的死亡率则增加约11％。由于高血压作为死亡原因常不在死亡诊断书上记录,故对这些数据难以评价。
In western countries, atherosclerotic vascular disease is the leading cause of death, and hypertension is one of its important precursors. About half of all deaths in the United States are caused by atherosclerotic lesions involving the coronary, cerebral and peripheral bloodstreams, with coronary heart disease accounting for about two-thirds of all deaths. 15 to 20% of adults in the United States have high blood pressure, 5% have confirmed or suspected coronary heart disease, and about 50% of male coronary heart disease patients and 75% of female coronary heart disease patients have an estimated high blood pressure. From 1955 to 1965, the overall mortality rate for Hypertensive heart disease decreased by 46%, while the mortality rate for Coronary heart disease increased by about 11% over the same period. Since hypertension is often not recorded on the death certificate as a cause of death, it is difficult to evaluate these data.
