Oxidative stress in pericardial fluid and plasma and its association with ventricular function

We found that oxidative stress determined by a simple malondialdehyde (MDA) assay, correlated in plasma and pericardial fluid, and this parameter was associated with left ventricular end systolic diameter. Conclusion: Plasma and pericardial fluid malondialdehyde levels can be used as an early marker of ventricular dysfunction.
