About this study
To evaluate additional cardiovascular risk factors using data from the VA HDL Intervention Trial (VA-HIT).
Read the detailed description
BACKGROUND:
The VA HDL Intervention trial (VA-HIT) was a multicenter, placebo controlled, randomized trial that showed that gemfibrozil significantly reduced major cardiovascular events in 2531 men with coronary heart disease, low levels of low density lipoprotein (LDL) cholesterol and low levels of high density lipoprotein (HDL) cholesterol. In addition to its unique lipid profile, the VA-HIT population also had a high prevalence of diabetes, impaired fasting glucose, or high fasting plasma insulin; central obesity; and hypertension, which are all components (together with high triglycerides and low HDL-cholesterol) of a constellation of risk factors known as the metabolic syndrome. Since prior clinical trials have not enrolled this type of population, the VA- HIT database is a unique resource.
DESIGN NARRATIVE:
The study used the VA-HIT database to study additional risk markers that were measured in the study population of 2,531 men with coronary heart disease. Specific analyses were: 1) the association between levels of glucose tolerance, insulin resistance and other features of the metabolic syndrome, occurrence of major cardiovascular outcomes, and gemfibrozil efficacy; 2) the effect of gemfibrozil on progression of carotid atherosclerosis, as measured by B-mode ultrasound; 3) the association between LDL particle size distribution and lipoprotein subclass distribution; homocysteine; lipoprotein(a); C-reactive protein, tissue plasminogen activator; fibrinogen; and factor VII; major cardiovascular outcomes and gemfibrozil efficacy.
The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.

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?

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?
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 16 Mar 2016.
