摘要

We thank Kawada for the interest in our paper [1] and comments. In the study to which he refers, we found that serum pro-oxidant-antioxidant balance (PAB) values were significantly higher in patients with defined coronary artery disease (CAD) than in healthy controls. While there was no association between diastolic function and serum PAB values or antioxidized low-density lipoprotein IgG titers, PAB values were inversely and significantly associated with ejection fraction. We concluded that serum concentrations of a marker of oxida-tive stress (PAB values) were inversely associated with cardiac function. PAB is a relatively simple index that could be used for risk assessment in CAD patients.
