The primary purpose of this project is to investigate risk factors for coronary heart disease (CHD) and stroke in the elderly. Risk factors for the development and progression of cardiovascular diseases will be examined in an elderly cohort. Risk factors for development of overt cardiovascular disease in an older population with prevalent atherosclerosis may differ from those related to the development of atherosclerosis in a younger population. In an elderly population with prevalent atherosclerosis it is important to assess the prediction of clinical disease from measures of preclinical disease such as cartoid atherosclerosis. The primary objective of the Ultrasound Reading Center is to develop and implement a system to assess atherosclerosis in the carotid arteries using ultrasound. This will involve 1) coordinating development of a protocol for ultrasound examinations at the field Centers and a method for evaluating extent of carotid atherosclerosis, 2) training ultrasound technicians of each Field Center, 3) interpreting all ultrasound examinations and 4) monitoring the ultrasound examinations at all field Centers. During the periods of data collection, the Ultrasound Reading Center shall have the responsibility of assessing within and between individual variation among technicians and coders. The contractor shall serve as the Ultrasound Reading Center for this study. Duties of the Ultrasound Reading Center include equipment selection, protocol development, technician training, central reading, and data transmittal and analysis for the ultrasonographic examinations within the study.

该项目的主要目的是调查风险因素 用于冠状动脉疾病（CHD）和老年人中风。 风险 心血管发展和发展的因素 疾病将在老年人群中检查。 风险因素 在老年人群中发展明显的心血管疾病 患有流行的动脉粥样硬化可能与与之相关的动脉粥样硬化有所不同 年轻人口中动脉粥样硬化的发展。 在患有动脉粥样硬化的老年人群中 评估从 临床前疾病的测量，例如核切片性动脉粥样硬化。 超声阅读中心的主要目标是 开发和实施一个系统来评估动脉粥样硬化 颈动脉使用超声。 这将涉及1） 协调超声检查协议的制定 在现场中心和一种评估颈动脉范围的方法 动脉粥样硬化，2）训练每个领域的超声技术人员 中心，3）解释所有超声检查和4） 监视所有现场中心的超声检查。 在数据收集期间，超声阅读 中心有责任评估和 在技​​术人员和编码人员之间的个体变异之间。 承包商应作为超声阅读中心 这项研究。超声阅读中心的职责包括 设备选择，协议开发，技术人员培训， 中央阅读以及数据传输和分析 研究中的超声检查。
