About this study
To examine some of the psychosocial predictors of poor outcome among revascularized coronary artery disease patients.
Read the detailed description
BACKGROUND:
Percutaneous coronary revascularization procedures are increasingly used in the treatment of coronary artery disease, with approximately 300,000 interventions performed each year. Despite new developments in cardiology such as intra-coronary stents and anticoagulant pharmacological treatments, a major problem remains the frequent occurrence of coronary restenosis and new cardiac events within six months after the intervention. These adverse outcomes occur in one out of four patients and have substantial impact on the costs of medical care and patients' quality of life. Research indicated that hemostatic factors (e.g., fibrinogen, von Willebrand factor, and plasminogen activator inhibitor) promote the formation of blood clots and that these factors predict coronary restenosis. Moreover, prior longitudinal studies have also demonstrated that the psychosocial traits of hostility and depression affect clinical progression of coronary disease. These psychosocial factors significantly predict adverse long-term outcome after revascularization and both hostility and depression are known to affect blood clotting factors. In addition, acute mental and physical stress are reported to affect blood clotting factors (coagulation and fibrinolysis) and responses to stress are reported to be more pronounced in hostile individuals. However, previous research on predictors of adverse clinical outcome after percutaneous coronary revascularization has not examined stress-induced changes in hemostatic factors and the consequences of these responses for progression of coronary artery disease. Therefore, the study investigates whether psychosocial factors and responses to acute mental stress affect measures of the blood clotting process that are involved in progression of coronary disease, thereby increasing the risk of an adverse prognosis following percutaneous coronary revascularization. This study may improve the identification of patients at risk for recurrent cardiac events and provide further understanding of the pathophysiological mechanisms involved in the progression of coronary artery disease.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Diseases and Heart Diseases, 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 16 Mar 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 NCT00005554, which also lists 10 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 16 Mar 2016.
