Malondialdehyde-Modified LDL IgG Antibody Levels and Indices of Cardiac Function in Valvular Heart and Coronary Artery Disease Patients.

Objective: To compare the changes in anti-malondialdehyde-modified low-density lipoprotein (MDA-LDL) IgG levels among patients undergoing off-pump and on-pump coronary artery bypass grafting (CABG) or valvuloplasty.

Subjects And Methods: A total of 38, 39 and 34 patients who underwent off-pump CABG, on-pump CABG and valvuloplasty, respectively, were enrolled in this study. Serum anti-MDA-LDL IgG values were measured 24 h before and after the operative procedures and at discharge.

Prooxidant-antioxidant balance and cardiac function in patients with cardiovascular disease following cardiac surgery.

Background And Aim Of The Study: Cardiopulmonary bypass (CPB) is used during on-pump coronary artery bypass grafting (CABG) and heart valvular replacement surgery, and is associated with the induction of oxidative stress. The aim of the study was to assess the association between indices of cardiac function and prooxidant-antioxidant balance (PAB) values in patients undergoing valve replacement surgery and on-or off-pump CABG.

Methods: Data were obtained from 44, 33, and 41 patients undergoing off-pump CABG, on-pump CABG, and valve replacement surgery, respectively.

Prooxidant-antioxidant balance and antioxidized LDL antibody level values and cardiac function in patients with coronary artery disease.

Objectives: We studied the association between the prooxidant-antioxidant balance (PAB), anti-malondialdehyde-modified low-density lipoprotein (oxidized LDL, ox-LDL) IgG antibody and indices of cardiac function (systolic and diastolic function) in patients with coronary artery disease (CAD).

Methods: Fifty-five patients with established CAD were selected, and serum levels of anti-ox-LDL IgG and PAB values were measured and compared with 40 matched healthy controls. Systolic and diastolic functions were determined for all patients.

Changes in anti-heat shock protein 27 antibody and C-reactive protein levels following cardiac surgery and their association with cardiac function in patients with cardiovascular disease.

The relationship between serum anti-heat shock protein (Hsp)27 antibody and high sensitive C-reactive protein (hs-CRP) levels and indices of cardiac function were investigated in patients undergoing coronary artery bypass grafting (CABG) or heart valve replacement. The changes in anti-Hsp27 antibody titers and hs-CRP levels were compared among patients undergoing off-pump and on-pump CABG or valvular heart replacement. Fifty-three patients underwent off-pump, on-pump CABG, and heart valvular replacement in each group.

Anti-heat shock protein 27 titers and oxidative stress levels are elevated in patients with valvular heart disease.

We studied the immune responses to heat shock protein (Hsp)-27 and pro-oxidant-antioxidant balance (PAB) values in patients with valvular heart disease, but free of angiographically evident coronary artery disease (CAD). Patients who were candidates for valvuloplasty surgery and 30 healthy matched controls were recruited. The anti-Hsp-27 antibody titers were 0.

The Role of Unknown Risk Factors in Myocardial Infarction.

Background: Atherosclerosis of coronary arteries is the most common cause of myocardial infarction (MI), which is initiated from childhood and progresses gradually by aging. Several risk factors influence its progress, and are categorized as classic, traditional and novel factors. The role of unknown risk factors is becoming increasingly more significant recently.

Tranexamic acid reduces blood loss in off-pump coronary artery bypass surgery.

Objective: This study was designed to evaluate the hemostatic effect of tranexamic acid in off-pump coronary artery bypass surgery.

Design: A prospective, randomized, double-blind, placebo-controlled study.

Setting: The Department of Anesthesiology and Cardiac Surgery, Medical Sciences University.
