DESCRIPTION: (Adapted from Investigator's Abstract) The proposed project constitutes part of a growing body of research designed to understand not only the secular trends in mortality, morbidity, survival, and disability levels for selected major chronic diseases among older persons in the United States, but also the implications of the findings for health care utilization. Specifically, the application presents plans for a retrospective study of successive cohorts of a well-defined and well-documented elderly population for the purpose of identifying and explaining trends in congestive heart failure (CHF) incidence, survival, comorbidities and health services utilization during the 25-year period 1970-1994. The study sample consists of two successive period cohorts of elderly people, identified for each of two five-year periods, 1970-1974 and 1990-94. The application presents the following hypotheses: 1) incidence of CHF has decreased among the younger old (65-74 years of age); 2) incidence of CHF has increased among the older old (75 years of age or above); 3) one-year survival time has increased following onset of incident CHF; and 4) prevalence of hypertension has decreased and prevalence of myocardial infarction and other manifestations of coronary artery disease have increased among incident cases of CHF. This project builds upon ongoing work of the investigators, related to a number of recent NIH research priorities, including stroke trends (NINDS), hip fracture trends (NIA), and congestive heart failure trends (NHLBI).

描述：(改编自《调查者摘要》)提议的项目 构成了越来越多的研究的一部分，旨在了解 只有死亡率、发病率、存活率和伤残的长期趋势 美国老年人中某些主要慢性病的水平 以及这些研究结果对医疗保健的影响 利用率。具体地说，该应用程序提供了 对定义明确的和 有良好记录的老年人口，以识别和 解释充血性心力衰竭(CHF)发病率、存活率、 25年期间的合并症和卫生服务利用情况 1970-1994年。 研究样本由两个连续的老年人时期队列组成 在1970-1974年和1990-94年这两个五年期中的每一个时期确定的人。 该应用提出了以下假设：1)CHF的发生率 在较年轻的老年人(65-74岁)中有所下降；2)心力衰竭的发生率 在老年人(75岁或以上)中有所增加；3)一年 发生心力衰竭后存活时间延长；以及4) 高血压患病率下降，心肌梗塞患病率下降 梗塞和其他冠状动脉疾病的表现有 在CHF发病病例中有所增加。该项目建立在正在进行的基础上 调查人员的工作，与NIH最近的一些研究有关 优先事项，包括中风趋势(NINDS)、髋部骨折趋势(NIA)和 充血性心力衰竭趋势(NHLBI)。
