About this study

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.

Read the detailed description

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.

The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiovascular Diseases and Cerebrovascular Accident, run by National Heart, Lung, and Blood Institute (NHLBI).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00005395, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2016.
