1930年,心血管病在美国就超过了传染病成为首要的死因。虽然今天心脏病仍居死因首位,但1950年来死亡率的下降已达30%,而其中2/3的下降见于1970年以后。心血管病在45岁以上的人中仍然是主要死因,但在25～44岁者中则已降为第三位。评价心血管病死亡率下降时必须考虑多种因素,例如即时和长期冠心监护的内、外科技术发展使患者能得到更好的心肺复苏及康复治疗的机会,另一主要因素是认识到心脏病的关键性易患因素并努力改变这些因素,以及医疗补助及医疗照顾方案等社会经济改革都有助于降低死亡率。治疗概念的改变
In 1930, cardiovascular disease became the leading cause of death in the United States over infectious diseases. Although heart disease remains the top cause of death today, the death rate has dropped by 30% in 1950, with two-thirds of the decline seen since 1970. Cardiovascular disease remains the leading cause of death among people over the age of 45, but it has dropped to third place among those aged 25-44. There are a number of factors that must be considered when assessing the decline in CVD mortality. For example, advances in internal and external surgical techniques for immediate and long-term coronary care provide patients with better opportunities for cardiopulmonary resuscitation and rehabilitation. Another major factor is the recognition of heart The key risk factors for disease and trying to change these factors, as well as socio-economic reforms such as Medicaid and Medicaid programs all help to reduce mortality.
