CONGESTIVE HEART FAILURE TRENDS IN THE ELDERLY 1970-94

描述：（改编自研究者摘要）拟议项目 构成了越来越多的研究机构的一部分，这些研究旨在了解 只有死亡率、发病率、存活率和残疾率的长期趋势 美国老年人中某些主要慢性病的发病率 同时也揭示了这些发现对医疗保健的影响 利用率 具体来说，该应用程序提供了一个 对一个明确定义的连续队列进行回顾性研究， 有充分记录的老年人口，以确定和 解释充血性心力衰竭（CHF）的发病率，生存率， 25年期间的合并症和卫生服务利用 1970-1994. 研究样本包括两个连续的老年人队列， 1970-1974年和1990- 1994年两个五年期的人口。 本申请提出了以下假设：1）CHF的发病率 在年轻老年人（65-74岁）中降低; 2）CHF的发生率 在老年人（75岁或以上）中有所增加; 3）一年 CHF发作后生存时间延长;以及4） 高血压患病率下降，心肌梗死患病率下降， 梗塞和冠状动脉疾病的其它表现 在CHF的事件病例中增加。 该项目建立在正在进行的 研究人员的工作，与最近的一些NIH研究有关， 优先事项，包括卒中趋势（NINDS）、髋部骨折趋势（NIA），以及 充血性心力衰竭趋势（NHLBI）。

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).
