چکیده
OBJECTIVE This study was conducted to determine whether or not depression is associated with higher levels of inflammatory markers in patients recovering from acute coronary syndromes. METHOD Plasma levels of soluble intercellular adhesion molecule 1 (sICAM-1) and interleukin-6 (IL-6) and the serum level of C-reactive protein were measured in 481 patients 2 months after hospitalization for acute coronary syndromes. Diagnosis of major depression was based on the Structured Clinical Interview for DSM-IV. RESULTS Depressed patients showed significantly higher sICAM-1 levels, a difference that remained significant after adjustment for potential confounders (gender, smoking, presence of metabolic syndrome). Although there was no significant association between depression and IL-6, there was an interaction between depression and statin therapy for levels of C-reactive protein. Depressed patients not taking statins had markedly higher C-reactive protein levels than did nondepressed patients. There was no relationship with depression in those receiving statins. CONCLUSIONS These results suggest chronic endothelial activation among depressed patients after acute coronary syndromes. Further research is needed to determine whether or not higher levels of sICAM-1 may identify a subgroup of depressed patients at particularly high risk for cardiac events among patients with established coronary artery disease or among those without previous coronary artery disease.

Introduction & Objective: Ischemic injury of endothelium is associated with prostaglandin synthesis and platelet adhesion and aggregation, which may be associated with the release of aldehydes such as malondialdehyde (MDA). C-reactive protein and cardiac troponin I have been proposed as diagnostic markers of acute coronary syndromes. In this study, we compared the usefulness of plasma MDA as a ...

Introduction: Coronary artery disease (CAD) is among the most common, serious, chronic and life- threatening illnesses in the world. CAD represents a spectrum of conditions, with acute myocardial infarction at one end of it and silent ischemia at the other. There is growing evidence on importance of prognosis of C- reactive protein (CPR) in unstable angina and this protein is a maker of an adve...

OBJECTIVE To determine whether inflammatory markers prospectively predict depressive symptom severity 12 months later in heart failure (HF) patients. METHODS In 30 HF patients we assessed depressive symptom severity by the Beck depression inventory (BDI) at baseline as well as 12 months later. We measured circulating levels of the soluble intercellular adhesion molecule (sICAM)-1, the cytokin...
