Canpolat Ugur,Çetin Elif Hande,Cetin Serkan,Aydin Selahattin,Akboga Mehmet Kadri,Yayla Cagri,Turak Osman,Aras Dursun,Aydogdu Sinan Clinical and applied thrombosis/hemostasis : official journal of the International Academy of Clinical and Applied Thrombosis/Hemostasis BACKGROUND:Previous studies proposed that both inflammation, oxidative stress, and impaired endothelial dysfunction have a significant role in occurrence of slow coronary flow (SCF). monocyte-to-high density lipoprotein cholesterol ratio (MHR) is a recently emerged indicator of inflammation and oxidative stress, which have been studied only in patients with chronic kidney disease. HYPOTHESIS:We aimed to assess the relationship between MHR and SCF. METHODS:Patients who had angiographically normal coronary arteries were enrolled in this retrospective study (n = 253 as SCF group and n = 176 as control group). Patients who had corrected thrombolysis in myocardial infarction frame counts (cTFCs) above the normal cutoffs were defined as with SCF. RESULTS:The MHR and high-sensitivity C-reactive protein (hsCRP) were significantly higher in the SCF group. In correlation analysis, MHR has a significantly positive correlation with cTFC and serum hsCRP levels (P < .001). In multivariate logistic regression analysis, MHR was found as independently associated with the presence of SCF (odds ratio: 1.24, P < .001). CONCLUSION:Higher MHR which indicates an enhanced inflammation and oxidative stress was significantly and independently associated with the presence of SCF. Besides, MHR was positively correlated with serum hsCRP level as a conventional marker for systemic inflammation. 10.1177/1076029615594002
    Increased Platelet to Lymphocyte Ratio is Related to Slow Coronary Flow. Akboga Mehmet Kadri,Canpolat Ugur,Balci Kevser Gulcihan,Akyel Ahmet,Sen Fatih,Yayla Cagri,Cay Serkan,Aras Dursun,Aydogdu Sinan Angiology Previous studies showed that both inflammation and platelets have a role in development of slow coronary flow (SCF). Platelet to lymphocyte ratio (PLR) as an emerging inflammatory indicator was significantly associated with adverse cardiovascular events. Therefore, we aimed to assess the relationship between PLR and SCF. Patients who had angiographically normal coronary arteries were enrolled in this retrospective study (n = 221 as SCF group and n = 293 as control group). Patients who had thrombolysis in myocardial infarction frame counts (TFC) above the normal cutoffs were considered to have SCF. Both PLR and C-reactive protein (CRP) were significantly higher in the SCF group. In correlation analysis, PLR has a significantly positive correlation with the left anterior descending artery TFC (P = .001), circumflex artery TFC (P < .001), right coronary artery TFC (P < .001), and serum CRP level (P < .001). In multiple logistic regression analysis, PLR was independently associated with presence of SCF (odds ratio: 1.014, P < .001). In conclusion, higher PLR levels were significantly and independently related to the presence of SCF. Besides, PLR was positively correlated with serum CRP level as a conventional marker for systemic inflammation. 10.1177/0003319715574625
    Plasma Choline as a Diagnostic Biomarker in Slow Coronary Flow. Zhu Yuan-Ting,Zhu Ling-Ping,Wang Zhen-Yu,Qiu Xue-Ting,Wu Wan-Zhou,Liu Wei-Wang,Feng Yu-Yu,Xiao Wen-Kai,Luo Xin,Li Zhen-Yu,Li Chuan-Chang Cardiology research and practice Aim:The slow coronary flow (SCF) phenomenon was characterized by delayed perfusion of epicardial arteries, and no obvious coronary artery lesion in coronary angiography. The prognosis of patients with slow coronary flow was poor. However, there is lack of rapid, simple, and accurate method for SCF diagnosis. This study aimed to explore the utility of plasma choline as a diagnostic biomarker for SCF. Methods:Patients with coronary artery stenosis <40% evaluated by the coronary angiogram method were recruited in this study and were grouped into normal coronary flow (NCF) and SCF by thrombolysis in myocardial infarction frame count (TFC). Plasma choline concentrations of patients with NCF and SCF were quantified by Ultra Performance Liquid Chromatography Tandem Mass Spectrometry. Correlation analysis was performed between plasma choline concentration and TFC. Receiver operating characteristic (ROC) curve analysis with or without confounding factor adjustment was applied to predict the diagnostic power of plasma choline in SCF. Results:Forty-four patients with SCF and 21 patients with NCF were included in this study. TFC in LAD, LCX, and RCA and mean TFC were significantly higher in patients with SCF in comparison with patients with NCF (32.67 ± 8.37 vs. 20.66 ± 3.41,   <  0.01). Plasma choline level was obviously higher in patients with SCF when compared with patients with NCF (754.65 ± 238.18 vs. 635.79 ± 108.25, =0.007). Plasma choline level had significantly positive correlation with Mean TFC ( = 0.364, =0.002). Receiver operating characteristic (ROC) analysis showed that choline with or without confounding factor adjustment had an AUC score of 0.65 and 0.77, respectively. Conclusions:TFC were closely related with plasma choline level, and plasma choline can be a suitable and stable diagnostic biomarker for SCF. 10.1155/2020/7361434
