Abstract:
OBJECTIVE:To investigate the change of serum myeloperoxidase (MPO) and lipoxin A4 (LXA4) in coronary heart disease (CHD) patients with anxiety and depression and its clinical significance.
METHODS:From December 2010 to February 2011, 143 CHD patients and 44 non-CHD patients (the control group) hospitalized in the Department of Cardiology at the Second Xiangya Hospital were enrolled. The hospital anxiety and depression scale (HADS) was used to evaluate the psychological state of all patients and the CHD patients were assigned to an anxiety and depression group (n=57) or a non-depression and anxiety group (n=86). The serum levels of high sensitive C-reactive protein (Hs-CRP), MPO, and LXA4 were examined, and the ratio of MPO and LXA4 (M/L) was calculated.
RESULTS:The levels of Hs-CRP, MPO, and LXA4 as well as M/L ratios in both CHD groups were significantly higher than those in the control group (all P<0.01). Compared with the non-anxiety and depression group, the levels of MPO and LXA4, and M/L ratios in the anxiety and depression group increased (all P<0.05). Correlation analysis showed that MPO was positively correlated with the score of HADS-total (HADS-t), HADS-anxiety (HADS-a), or HADS-depression (HADS-d), while LXA4 was negatively correlated with HADS-t or HADS-d. Multiple ordinal logistic regression analysis revealed that higher HADS-t score, stable angina, unstable angina, and acute myocardial infarction were the independent impact factors for the elevation of M/L ratio.
CONCLUSION:Anxiety and depression may aggravate the inflammatory response in CHD patients. The imbalance between inflammation and anti-inflammation may be part of the mechanism.
