About this study

To assess the association of immunogenetic factors with onset of coronary heart disease and the interrelationship of these factors with standard coronary heart disease risk factors.

Read the detailed description

BACKGROUND:

Although the familial clustering of coronary heart disease has been well documented, it is unclear as to whether the familial clustering can be explained by shared environmental factors by members of a family or by clustering of risk factors having a genetic component such as blood pressure, familial hyperlipidemia and/or diabetes. Studies indicate that a family history of coronary disease may be an independent risk factor. Major histocompatibility complex genetic markers to identify individuals at risk within a family may be useful. In 1985 when the study began, there was a paucity of data dealing with the interrelationship of family history, genetic markers, immunological markers, and traditional risk factors.

DESIGN NARRATIVE:

In this case-control study, the study population consisted of incident cases who presented to the Georgia Heart Clinic in La Grange, Georgia with coronary heart disease. The majority of the subjects were from three counties in mideastern Alabama and from counties in midwestern Georgia. All subjects had undergone diagnostic coronary angiography. A determination was made in patients and controls of the association of major histocompatibility complex genetic markers HLA-A, -B, -C, -DR, C4 and BF, C3, the restriction fragment length polymorphisms (RFLP's) flanking the apolipoprotein AI and insulin genes, presence of autoantibodies, and family history of coronary disease, diabetes, or hypothyroidism. The frequency of these variables was compared with the standard coronary risk factors of family history, hypertension, lipid abnormalities, lifestyle, Type A behavior, obesity and with diseases such as diabetes and hypothyroidism. An analysis was made of the strength of these variables for predicting those individuals at risk and whether there were variables which predict severity of disease based on 1, 2, or 3 vessel involvement.

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 Coronary Disease, 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 13 May 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 NCT00005184, which also lists 4 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 13 May 2016.
