OBJECTIVE: Type 2 diabetes mellitus (T2DM) is known to be associated with endothelial dysfunction (ED). Reducing ED can attenuate the occurrence of cardiovascular diseases. One of the indicators of ED is decreased coronary blood flow (CBF). Sodium-glucose co-transporter 2 inhibitors (SGLT-2is) are known to directly improve ED in both euglycemic and hyperglycemic conditions and have been shown to decrease the incidence of major cardiovascular events. We aimed to investigate whether SGLT-2is improves CBF in patients with T2DM, who have angiographically normal or nearly normal coronary arteries. PATIENTS AND METHODS: In this single-center retrospective study, all patients who underwent coronary angiography between January 2017 and September 2022 were screened. We designed the study by dividing the patients into two groups - those who used conventional antidiabetic medications (CAM) together with SGLT-2is (patients using an SGLT-2 inhibitor for at least 3 months) and those who used only conventional antidiabetic medications. Of the 18,205 patients who underwent coronary angiography, 5,040 patients had T2DM. After exclusion, 288 patients were divided into two groups - those who used CAM together with SGLT-2is and those who used only CAM. CBF was assessed by thrombolysis in myocardial infarction (TIMI) frame counting. RESULTS: Two hundred eighty-eight patients who had T2DM and met the inclusion criteria were included in our study. The patients were divided into two groups - those who used CAM together with SGLT-2is (n = 75) and those who used only CAM (n = 213). The median age in the group that used CAM together with SGLT-2is was 55 (51-64), where 52 (69.3%) patients were female. The mean TIMI frame count (TFC) was 23.5 in the group using CAM + SGLT-2is and 27.5 in the group using only CAM. In the multivariable linear regression analysis, the mean TFC was significantly lower in the group using CAM together with SGLT-2is compared to the group using only CAM [ß-coefficient = -12.766, 95% Cl: -5.304; -3.887, p < 0.001]. Moreover, there was a statistically significant correlation between an increase in BMI and hemoglobin with an increase in the mean TFC [ß-coefficient = 3.018, 95% Cl 0.037-0.175, p = 0.003 a nd ß -coefficient = 2 .316, 9 5% C l 0 .033-0.405, p = 0.021, respectively]. CONCLUSIONS: We have demonstrated that the use of SGLT-2is improves coronary artery blood flow in patients with T2DM who have normal or nearly normal coronary angiography. [ABSTRACT FROM AUTHOR]

Background: Mesenchymal stem cells (MSCs) have the ability to self-renew and are multi-potent. They are a primary candidate for cell-based therapy due to their potential anti-cancer effects. The aim of this study was to evaluate the in vitro anti-leukemic effect of Wharton's Jelly-derived MSC (WJ-MSC) on the leukemic cell lines K562 and HL-60., Methods: In this present study, WJ-MSCs were isolated from human umbilical cord. The cells were incubated according to the standard culture conditions and characterized by flow cytometry. For experiments, WJ-MSC and leukemic cells were incubated in the direct co-culture at a ratio of 1:5 (leukemia cells: WJ-MSC). HUVEC cells were used as a non-cancerous cell line model. The apoptotic effect of WJ-MSCs on the cell lines was analyzed using Annexin V/PI apoptosis assay., Results: After the direct co-culture of WJ-MSCs on leukemic cell lines, we observed anti-leukemic effects by inducing apoptosis. We had two groups of determination apoptosis with and without WJ-MSCs for all cell lines. Increased apoptosis rates were observed in K562 and HL-60 cell lines, whereas the apoptosis rates in HUVEC cells were low., Conclusions: MSCs are known to inhibit the growth of tumors of both hematopoietic and non-hematopoietic origin in vitro. In our study, WJ-MSC treatment strongly inhibited the viability of HL-60 and K562 and induced apoptosis. Our results also provided new insights into the inhibition of tumor growth by WJ-MSCs in vitro. In the future, WJ-MSCs could be used to inhibit cancer cells in clinical applications., (© 2024.

Background: Mesenchymal stem cells (MSCs), are a novel therapeutic option as the most common cell source, play an important role in the immunomodulation. In this study, it was aimed to determine the effect of MSCs on cytokines secreted by the immune system cells., Methods: Intracellular cytokine levels (Interleukin-4 (IL-4), Interferon-γ (IFN-γ), and Interleukin-17 (IL-17)) detected by flow cytometry before and after co-culture between peripheral blood mononuclear cells (PBMCs) and MCSs. At the same time, supernatant cytokine levels were measured using the ELISA., Results: In our study, MSCs were isolated from cord blood (CB) and Wharton's Jelly (WJ), and their surface markers (CD44 (100%), CD73 (99.6%), CD90 (100%), CD105 (88%)) shown by flow cytometry method. Both CB-MSCs and WJ-MSCs were used in co-culture MSC/PBMC ratios of 1/5 and 1/10, incubation times of 24 h and 72 h. In the present study, when we compared co-cultures of CB-MSC or WJ-MSC with PBMCs, intracellular levels of cytokines IFN-γ, IL-17 (pro-inflamatory) and IL-4 (anti-inflamatory) were increased, and supernatant levels were decreased significantly (p < 0.05). The level of transforming growth factor beta (TGF-β) (anti-inflamatory) was significantly decreased for both CB-MSC and WJ-MSC in supernatant (p < 0.05)., Conclusions: It was investigated pro-inflammatory and anti-inflammatory effects of CB-MSCs and WJ-MSCs on PBMCs with the obtained results. According to the results, MSCs demonstrated different immunologic effects after the incubation time and ratios. For further studies, it should be known between interaction of MSCs and immune system., (© 2023. The Author(s), under exclusive licence to Springer Nature B.V.)

Background: Peripheral artery disease (PAD) is part of the systemic atherosclerotic process that is highly associated with cardiovascular diseases. Despite successful endovascular treatment (EVT) strategies, mortality and morbidity rates still remain higher in PAD patients. C-reactive protein (CRP) and albumin are biomarkers of inflammation and malnutrition that play key roles in the progression of peripheral arterial disease. In this study, we aimed to investigate the relationship between CRP-to-albumin ratio (CAR) and mortality and amputation-free survival in patients with PAD after successful EVT., Method: Our study enrolled 149 consecutive patients who underwent EVT on atherosclerotic obstruction of iliac, femoral, popliteal and/or below-knee arteries with the clinical features of PAD and/or chronic limb-threatening ischaemia between January 2015 and January 2020. Clinical and prognostic follow-up of patients had been done at the outpatient clinic and were collected from institution's medical records., Results: The mean follow-up period was 22 months (14-40). All-cause mortality and amputation rates of patients in the high CAR group were significantly higher than those in the low CAR group (21.3% vs. 6.8% and 18.7% vs. 5.4%, respectively). Kaplan-Meier survival analysis showed significantly better survival for patients in the low CAR group (log-rank p = 0.0058). In multivariate logistic regression analysis, CAR was found to be an independent predictor of amputation and all-cause mortality even after adjusting for other confounding risk factors. ROC curve analysis revealed the optimal cut-off value of CAR for predicting all-cause mortality and amputation to be >1.476 with a sensitivity of 48.5% and specificity of 94.0%., Conclusion: The inflammatory state reflected by CAR levels was strongly associated with all-cause mortality and amputation after EVT in patients with PAD. Furthermore, CAR was found to be an independent predictor of these clinical outcomes after adjusting for other clinically associated parameters.

We aimed to examine the effect of a history of COVID-19 on myocardial ischemia in single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) in patients who presented with shortness of breath and/or chest pain after recovery. For this single-center retrospective study, patients who presented at cardiology outpatient clinics and had SPECT-MPI were screened. A total of 1888 patients were included in the study, 340 of whom had a history of COVID-19. 64 patients with > 50% stenosis on coronary angiography were excluded from the study. The primary outcome of the study was abnormal MPI. In the study population, the median age was 56 (49-64 IQR) years, and 1127 (65%) of the patients were female. Abnormal MPI was detected in 77 patients (23%) in the COVID-19 group and in 244 patients (16%) in the non-COVID-19 group. After adjustment was performed for clinical predictors using Bayesian logistic regression, an important association was found between the presence of a confirmed prior COVID-19 infection and abnormal MPI (posterior median odds ratio, 1.70 [95% CrI, 1.20-2.40], risk difference, 9.6% [95% CrI, 1.8%, 19.7%]). In SPECT-MPI, ischemia rates were observed to be higher in COVID-19 group and it was found that a confirmed prior COVID-19 might predict of abnormal MPI., (© 2021.

Background: Congenital myopathies (CMs) are a group of rare genetic muscle disorders. Cardiac involvement can be seen in these patients. We aimed to evaluate the myocardial strain parameters by 2D speckle-tracking echocardiography (STE) in patients with CM., Materials and Methods: Twenty-four patients with CM whose diagnosis was confirmed by genetic analysis or muscle biopsy were included in the study, and 48 patients were involved as a control group. Left ventricular ejection fraction (LVEF%) was calculated by biplane Simpson method, and myocardial strain analysis was performed by 2D STE., Results: The median age of the study population was 26 (19-35 interquartile range [IQR]) and 43 (60%) were women. In the analysis performed after the exclusion of two patients with multiminicore disease (MMD) who developed heart failure, although mild, LVEF% (62 [60-65 IQR] vs. 64 [63-66 IQR], P = 0.008) and right ventricular global longitudinal strain (RVGLS) were significantly lower in the CM group (-21.8 [-19.7, -24.9 IQR] vs. -23.9 [-22.4, -25.6 IQR], P = 0.0017). Left ventricular global longitudinal strain (LVGLS) was observed similarly in both groups (-19.9 [-18.7, -20.7 IQR] vs. -20.5 [-19.3, -21.9 IQR], P = 0.069). LVEF% (33 and 46), LVGLS (-7.5 and -10.7), and RVGLS (-14.9 and -16.1) values were low in two siblings with MMD., Conclusion: Although LVEF% and RVGLS were significantly lower in the CM group, LVGLS was similar. The decrease in RVGLS and LVEF% was mild, and heart failure was not observed in any patient except MMD patients who were not included in the analysis., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Cardiovascular Echography.)

Background: Peripheral arterial disease is associated with increased cardiovascular mortality and morbidity. C-reactive protein and albumin are biomarkers of inflammation and malnutrition that play key roles in the pathophysiological pathways involved in the progression of atherosclerosis and peripheral arterial disease. In this study, we aimed to assess the relationship between C-reactive protein to albumin ratio and the suprapopliteal peripheral arterial disease severity and complexity as assessed by TransAtlantic Inter-Society Consensus-II (TASC-II) classification., Method: Our study enrolled 224 consecutive patients referred for peripheral angiography with the clinical features of possible peripheral arterial disease at a tertiary care center between January 2016 and September 2019. Level of disease and lesion characteristics were defined with reference to angiographic findings according to the TASC-II classification., Results: C-reactive protein/albumin ratio levels were significantly higher in TASC-II class C and D than in TASC-II class B patients with a median level of 1.8 to 2.1 vs 1.4, respectively ( p  = 0.018). In multivariate regression analysis, C-reactive protein to albumin ratio remained an independent predictor of severe peripheral arterial disease. The predictive performance of C-reactive protein to albumin ratio, C-reactive protein, and albumin were compared by Receiver Operating Characteristic curve analysis. C-reactive protein to albumin ratio surpassed C-reactive protein and albumin in predicting peripheral arterial disease severity and complexity. A level of C-reactive protein to albumin ratio  > 0.14 predicted a higher grade of suprapopliteal TASC-II class with sensitivity and specificity of 68.2% and 56.0%, respectively., Conclusion: C-reactive protein to albumin ratio was strongly associated with peripheral arterial disease severity and complexity, as assessed by TASC-II classification. Also, C-reactive protein to albumin ratio was found to be a more accurate marker than C-reactive protein and albumin alone in predicting more severe and complex lesions in patients with peripheral arterial disease.

Background: The effect of favipiravir on the QTc interval during the treatment of Coronavirus Disease 2019 (COVID-19) patients is unclear. Thus, the current study objective was to evaluate any change in the QTc interval in patients who were hospitalized due to COVID-19 receiving favipiravir treatment., Method: Patients hospitalized with COVID-19 were assessed in this single-center retrospective study. 189 patients, whose diagnosis was confirmed using real-time PCR, were included in the study. The patients were divided into three groups: those using hydroxychloroquine (Group 1, n = 66), hydroxychloroquine plus favipiravir (Group 2, n = 66), and favipiravir only (Group 3, n = 57). The QTc interval was measured before treatment (QTc-B) and 48 h after (i.e., the median) starting treatment (QTc-AT)., Results: The median age was 53 (39-66 IQR) and 97 (51%) of patients were female. The median QTc(Bazett)-change was 7 ms (p = 0.028) and 12 ms (p < 0.001) and in Group 1 and 2, respectively. In Group 3, the median QTc(Bazett)-change was observed as -3 ms and was not statistically significant (p = 0.247). In multivariable analysis, while there was a significant relationship between QTc-AT(Bazett) and hydroxychloroquine (β coefficient = 2687, 95%CI 2599-16,976, p = 0,008), there was no significant relationship with favipiravir (β coefficient = 0,180, 95% CI -6435-7724, p = 0,858). Similarly, there was a significant relationship between the QTc-AT interval calculated using the Fredericia formula and hydroxychloroquine (β coefficient = 2120, 95% CI 0,514-14,398, p = 0,035), but not with favipiravir (β coefficient = 0,111, 95% CI -6450- 7221, p = 0,911)., Conclusion: In the ECG recordings received in the following days after the treatment was started in COVID-19 patients, there was a significant prolongation in the QTc interval with hydroxychloroquine, but there was no significant change with favipiravir., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier Inc.

Objective: Many studies have examined the capability of electrocardiography (ECG) changes to predict the severity and prognosis of patients with acute pulmonary embolism (APE). RS time in ECG is potentially valuable in evaluating the prognosis of APE. In our study, we aimed to assess the predictive value of RS time, which is a novel electrocardiographic parameter of one-month mortality of APE., Methods: This retrospective study included 216 patients who were diagnosed with APE by pulmonary computed tomography angiography. RS time was measured from the ECG (inferolateral leads) at the time of hospital admission using a computer program (imagej.nih.gov/ij/). The patients were divided into two groups according to the median values of RS time: the group with RS time ≤ 60 msec (n:108) and the group with RS time > 60 msec (n:108). The groups were compared in terms of mortality., Results: In our study, the one-month mortality was 15.3% (33) in the patients hospitalized with APE. In the multivariate analysis, RS time prolongation (HR: 1.037; 95%CI: 1.005-1.065; p = .02) was independently correlated with mortality. The ROC curve analysis revealed that RS time > 64.8 msec predicted the one-month mortality in APE with a sensitivity of 68.6% and a specificity of 73.9% (AUC: 0.708; 95% CI: 0.643-0.768; p < .001)., Conclusion: As a novel ECG parameter, RS time could be measured for each patient with APE. Prolongation of RS time could be a useful index for predicting the one-month mortality of patients diagnosed with APE., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2020 Elsevier Inc.

Iron(III) and nickel(II) complexes bearing a thiosemicarbazone framework were synthesized by a one-pot synthesis method. The structures were characterized by elemental analysis, IR, 1 H NMR, APCI Mass, conductivity, magnetic moment measurements. Molecular and crystal structures of the iron(III) complex were obtained from single-crystal X-ray diffraction. The findings showed that the metal atom adopts a slightly distorted square-pyramidal coordination, with the four donor atoms of the thiosemicarbazone ligand defining the basal plane and a chloride atom occupying the apical position. In the crystal lattice, the structure is stabilized by intermolecular O─H···O and C─H···O interactions. The cytotoxic activity was studied by MTT assay, the expression levels of cytochrome P450 (CYP) enzymes by Western blot, and the lipophilicity (LogP) by using the shake-flask method, another pharmacokinetic parameter. The findings showed that the IC 50 values decreased with the decrease of the LogP values of the substances. Cytochrome P450 expression levels were found specific for each compound and each cell line. As a result, the pharmacokinetic properties of the newly synthesized thiosemicarbazone compounds are crucial for oral administration and provide us with clues for prospective in vivo studies., (© 2020 Wiley Periodicals, Inc.)

Because the phenomenon of no reflow has a poor prognosis in ST-segment elevation myocardial infarction (STEMI) patients and the atherogenic index of plasma (AIP) has been shown to be a strong predictor of coronary heart disease, we aimed to investigate the relationship between AIP and no-reflow in patients with acute STEMI who underwent primary percutaneous coronary intervention (PCI). A total of 763 consecutive STEMI patients (648 men; mean age 58 ± 12 years) who underwent primary PCI were recruited for this study. The patients were classified into a reflow group (n = 537) and a no-reflow group (n = 226) according to the postprocedural angiographic features of thrombolysis in the myocardial infarction flow of the infarct-related artery. The AIP value was significantly higher in the no-reflow group than in the reflow group [0.50 (0.38-0.65) vs. 0.39 (0.25-0.49) p < .001], and AIP was found to be an independent predictor of no-reflow development. The best cut-off value of AIP for predicting no-reflow was 0.54, with sensitivity of 46.02 and specificity of 84,73. In addition, the predictive power of AIP was greater than that of triglycerides and high-density lipoprotein cholesterol based on a receiver operator curve comparison. The AIP was independently associated with no-reflow in patients with STEMI after primary PCI. This might be a superior indicator compared to traditional lipid profiles.

Objective: Acute kidney injury (AKI), which is prevalent in ST-segment elevated myocardial infarction (STEMI) patients who have undergone primary percutaneous coronary intervention (PCI), is associated with poor cardiovascular outcomes. As high pulse pressure (PP) is associated with adverse cardiovascular events, the present study's aim was to evaluate the relationship between fractional PP (PPf) and AKI in patients with STEMI who underwent primary PCI., Subjects and Methods: All laboratory findings as well as echocardiographic and angiographic data of 1,170 consecutive STEMI patients were retrospectively screened. PPf was calculated from the pressures invasively measured after sheath insertion and before performing coronary angiography., Results: From 1,170 eligible STEMI patients (mean age 56 years, 18.2% female), AKI developed in 143 (12.2%) patients. The PPf and pulsatility index were significantly higher in patients with AKI than those without (0.53 ± 0.10 vs. 0.61 ± 0.10, p < 0.001, and 0.80 ± 0.03 vs. 0.82 ± 0.03, p < 0.001, respectively). PPf was also found to be associated with AKI in univariable (OR 2.183, 95% CI 1.823-2.614, p< 0.001) and multivariable (OR 1.874, 95% CI 1.513-2.322, p < 0.001) analysis. In-hospital mortality was higher in patients with AKI than those without., Conclusion: Invasively measured PPf, which can be easily measured and has no additional cost in STEMI patients undergoing coronary intervention, is an independent predictor of AKI. In addition, PPf is superior to other blood pressure values and derivatives in AKI prediction., (© 2020 The Author(s) Published by S. Karger AG, Basel.)

Eighteen of the iron(III) and nickel(II) complexes with tetradentate thiosemicarbazidato ligands were synthesized and described, by analytical and spectroscopic methods. Two complexes as an example to the iron and nickel centered ones were crystallographically analyzed to confirm the molecular structures. Cytotoxic effects of the complexes on K562 chronic myeloid leukemia cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. For comparison, human umbilical vein endothelial cells (HUVECs) was used as a noncancerous cell line. While four of the iron(III) complexes exhibited the antileukemic effect with 50% inhibition of cell growth (IC 50 ) values in the 3.4 to 6.9 μg/mL range on K562 cell line, the nickel(II) complexes showed no significant effect on both cell lines. The complexes Fe4, Fe5, and Fe6, bearing 4-methoxy substituent exhibited relatively high antiproliferative activity on both cell lines. Complex Fe3 with 3-methoxy and S-allyl groups exhibited a selectivity between K562 and HUVEC cells by IC 50 values of 6.9 and >10 μg/mL, respectively. Lipophilicity, a key parameter for bioavailability and oral administration, was found in the range of -0.3 and +1.3 that desired for drug active ingredients. The results were discussed in the context of a structure-activity relationship., (© 2019 Wiley Periodicals, Inc.)

Background/aim: The number of patients with heart transplantation has dramatically increased in the last decade. Considerable studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. We analyzed the dispersion of myocardial repolarization using electrocardiographic Tp-e interval and Tp-e/QTc ratio in patients with heart transplantation., Materials and Methods: This observational study included 38 patients (12 female and 26 male) with heart transplantation and 38 well-matched controls. From electrocardiograms, Tp-e interval and Tp-e/QTc ratio were calculated and compared between the 2 groups., Results: Noninvasive arrhythmia indicators including Tp-e interval (84.63 ± 14.17 ms vs 71.82 ± 7.47 ms, P < 0.001), Tp-e/QTc ratio (0.19 ± 0.04 vs 0.16 ± 0.02, P < 0.001) and QTc interval except QT interval were significantly higher in transplanted hearts compared to normal hearts., Conclusion: Patients with heart transplantation have increased myocardial dispersion of repolarization.

In this work, the usability of chitosan-co-hyaluronic acid cryogels as a tissue-engineering scaffold was investigated. Chitosan-co-hyaluronic acid cryogels were synthesized at subzero temperature. Cryogels which were composed of various compositions of chitosan and hyaluronic acid (0, 10, 20, 30 and 50wt% hyaluronic acid) was prepared. Morphological studies showed that the macroporous cryogels have been developed with 90-95% porosity. Particularly, the mechanical and biomaterial property of pure chitosan was improved by making copolymer with hyaluronic acid in different concentration. The MTT cell viability results demonstrated that the cryogels have no significant cytotoxicity effect on 3T3 fibroblast and SAOS-2 cells., (Copyright © 2017 Elsevier B.V. All rights reserved.)

In this study, zwitterionic phosphorylcholine grafted electrospun chitosan fiber was accomplished in three steps: (1) Azide groups on the chitosan were regioselectively replaced with hydroxyl side group and then the product was electrospun. (2) Chitosan based macroinitiator was prepared using an azide-alkyne click reaction from azide-functionalized electrospun chitosan fiber. (3) Poly(2-methacryloyloxyethyl phosphorylcholine) (MPC) was grafted onto the electrospun chitosan fiber by atom transfer radical polymerization (ATRP) in order to enhance cellular viability and proliferation of 3T3, ECV and Saos. The structure of surface modified chitosan was characterized by Fourier transform infrared spectrometer (FT-IR) and 1 H nuclear magnetic resonance ( 1 H NMR). The surface morphology of the nanofibers was investigated by scanning electron microscope (SEM). In-vitro cellular attachment and spreading experiments of 3T3, ECV304 and Saos were performed on electrospun chitosan fibers in the presence and the absence of MPC grafting. Poly(MPC) grafted electrospun fiber showed an excellent performance due to phosphorylcholine groups mimicking the natural phospholipid., (Copyright © 2016 Elsevier B.V. All rights reserved.)

Objective: The aim of this study was to compare health-related quality of life (HRQoL) measures between novel oral anticoagulants (NOACs) and warfarin-treated Turkish patients who had been started on oral anticoagulants (OACs) due to non-valvular atrial fibrillation (AF) and to determine the effects of OACs on patient's emotional status, anxiety and depression., Methods: A total of 182 patients older than 18 years with non-valvular AF and being treated with OACs for at least 6 months according to current AF guidelines who were admitted to outpatient clinics between July 2014 and January 2015 were included in this cross-sectional study. The exclusion criteria were receiving OACs for conditions other than non-valvular AF and being unable to answer the questionnaire. A questionnaire was administered to all participants to evaluate HRQoL, depression and anxiety. The mean differences between the groups were compared using Student's t-test; the Mann-Whitney U test was applied for comparisons of the medians., Results: The annual number of hospital admissions was significantly higher in the warfarin group (p<0.001), and all HRQoL scores were significantly lower and Hospital Anxiety and Depression Scale (HADS) score was higher in the warfarin group (p<0.001). History of any type of bleeding was significantly higher in the warfarin group (p<0.001). However, none of the patients had major bleeding. Among patients who experienced bleeding, all HRQoL scores were significantly lower and HADS score was significantly higher (p<0.001 and p=0.002, respectively)., Conclusion: Warfarin-treated patients had higher levels of self-reported symptoms of depression and anxiety and compromised HRQoL when compared with NOAC-treated patients. The results may be explained by higher rates of bleeding episodes and higher number of hospital admissions, which may cause restrictions in life while on warfarin treatment.

Objective: Mitral annular calcification (MAC) and atherosclerosis are similar in regard to risk factors and pathogenesis. Increased red blood cell distribution width (RDW) has been shown to be associated with atherosclerotic diseases. However, no data evaluating the association of MAC with RDW has been available. The aim of this cross-sectional study was to investigate the relationship between MAC and RDW among patients with various cardiovascular risk factors., Methods: A total of 623 patients (MAC-positive group: n=413; control group: n=210) admitted to our cardiology outpatient clinics were enrolled between March and November 2014. Demographic, clinical, and laboratory parameters of all participants were recorded. RDW was analyzed from complete blood samples of study participants., Results: Patients in MAC-positive group showed older age and higher rate of hypertension. Mean RDW value was significantly higher in MAC-positive group, compared to control group (15.3±1.4% vs. 13.9±1.4%, p<0.001). In Pearson correlation analysis, statistically significant and positive correlation was determined between neutrophil-lymphocyte ratio and RDW (r=0.284, p<0.001). In multivariate logistic regression analysis, age (OR: 1.041, p<0.001), hypertension (OR: 1.540, p=0.039), and RDW (OR: 5.351, p<0.001) were determined as independent predictors of MAC., Conclusion: RDW levels were significantly increased in patients with MAC, and RDW was determined as an independent predictor for presence of MAC. Therefore, increased RDW can be used as a marker of continuing inflammatory process in MAC patients.
