Honolulu Heart Program-Study of Stroke and Dementia Clinical Trials References presented on Clinical Trials Search is not intended to be a substitute for proven healthcare advice, trips or professional assistance by using a real medical. We aren't mDs. Always confer with your physician about Honolulu Heart Program-Study of Stroke and Dementia conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Honolulu Heart Program-Study of Stroke and Dementia Clinical research trials and Honolulu Heart Program-Study of Stroke and Dementia medical trials take place in hundreds of localities across the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectualness of new does drugs. The purpose of the studies / projects is to solve specific human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to discover treatments for all sorts of conditions, such as Honolulu Heart Program-Study of Stroke and Dementia. Honolulu Heart Program-Study of Stroke and Dementia Clinical Trials and other clinical trials permit volunteers to access healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for without cost, and every now and again they are compensated for their time. Sometimes there is a cost for a Honolulu Heart Program-Study of Stroke and Dementia clinical trial. Subjects often receive the most expert healthcare possible for their Honolulu Heart Program-Study of Stroke and Dementia condition. Risks are a reality, nevertheless, and could include additional or frequent dr. calls, healthcare dangers (perhaps life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with stern guidelines to protect clinical trials subjects.

Honolulu Heart Program-Study of Stroke and Dementia
For Condition: Dementia,Cardiovascular Diseases,Cerebrovascular Accident,Cerebrovascular Disorders
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To clarify the relationship of the arterial lesions to aging, define the influence of the arterial changes on the development of stroke, brain infarction, and dementia, and provide a better understanding of vascular dementia.
Details: BACKGROUND: Morphologic delineation of the arterial lesions will assist the use of experimental models to study molecular mechanisms underlying the lesions and the development of pharmacologic methods for controlling these mechanisms. Further examination of risk factors for the arterial lesions will indicate opportunities for prevention or modifying their evolution. DESIGN NARRATIVE: The study was based on data including risk factors and autopsy brain sections from deceased men from the Honolulu Heart Program. In this cohort, medial and intimal lesions of brain parenchymal arteries were significantly associated with brain infarction and three times more common in men dying of stroke than of non-cardiovascular causes. The specific aims of the study were 1) delineation of the morphologic characteristics of the brain parenchymal artery lesions, their regional anatomic distribution, and their relationship to changes in adjacent brain parenchyma and the degree of atherosclerosis in the major intracranial arteries; 2) characterization of the relationship in men between the arterial lesions and advancing age; 3) characterization in men over 60-65 years of age of the relationship of the arterial lesions to stroke, brain infarction or hemorrhage, and dementia; 4) identification of additional risk factors associated with the arterial lesions. The arterial lesions and adjacent brain parenchyma were examined with conventional histologic stains and immunohistochemical markers for specific cellular and extracellular components of the arterial wall. The prevalence and extent of each type of arterial lesion were determined at three anatomic sites. Baseline risk factors thought to be related to stroke and brain infarction were examined for association with the arterial lesions. Statistical tests of association were based on univariate and multivariate linear and logistic regression models controlled, when necessary, for age.
