ACCEPTED MANUSCRIPT To the Editor, I read the recent article entitled “Effect of serum YKL-40 on coronary collateral
T
development and SYNTAX score in stable coronary artery disease” by Akboga and
IP
colleagues with great interest [1]. They demonstrated that YKL-40 could be used as a
SC R
predictor of good collateral development and high SYNTAX score [1]. Presence of coronary collaterals has been shown to play critical roles on cardiovascular outcomes of patients with severe coronary artery disease (CAD). Well-developed collateral arteries may limit infarct

size, improve cardiovascular outcomes and survival [2]. A significant role of angiogenesis
MA
and inflammation in the pathophysiology of coronary collateral development (CCD) has been previously reported [1,2]. Recently, YKL-40, high-sensitivity C-reactive protein (hs-CRP), neutrophil, monocyte, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio

D
(PLR), and monocyte to high-density lipoprotein (HDL) cholesterol (MHR) have been used as easily available inflammatory biomarkers, and have been shown to be independent risk factors
CE P
for CCD, CAD, and cardiovascular events [4-8]. In this well presented study by Akboga et al. serum YKL-40 levels were significantly
AC
higher in the poor collateral group. Besides, white blood cells and hs-CRP levels were also higher whereas HDL-cholesterol levels were lower in the poor collateral group. However, in this study there is not any data regarding other easily available biochemical parameters associated with inflammation such as neutrophil, lymphocyte, monocyte, NLR, PLR and MHR. We believe that the combined information of multiple inflammatory biomarkers could be more useful and more reliable for evaluating the CCD in patients with severe CAD.
