RESUMEN

Aim    This study aimed to evaluate the potential relationships between atrial fibrillation (AF) and hematological indices, such as neutrophil / lymphocyte ratio (NLR), mean platelet volume (MPV), platelet / lymphocyte ratio (PLR), mean platelet volume / platelet (MPV / PLT), neutrophil / monocyte ratio (NMR), lymphocyte / monocyte ratio (LMR), systemic immune inflammation index (SII, platelet x neutrophil / lymphocytes), and monocyte / high-density lipoprotein ratio (MHR), that can be obtained from the complete blood count (CBC test).Material and method    This retrospective study included 150 patients aged 40-80 yrs who were diagnosed with AF, and 91 age- and gender-matched controls. Hematological indices and inflammation markers were evaluated.Results    In the AF group, NLR, PLR, SII, MHR, and MPV / PLT were elevated, and LMR was low. Multivariate regression analysis showed that hematological indices NLR, SII, and MHR were significant, independent, predictive factors for AF. ROC curves revealed the following significant sensitivity and specificity values: NLR 75 %, 52.3 %; LMR 61.3 %, 67.3 %; SII 67.4 %, 64.6 %; MHR 100 %, 56 %.Conclusion    NLR, PLR, LMR, SII, MPV / PLT, and MHR may be useful in the early prediction of AF development. It is strongly emphasized that among these variables, MHR, may be the best independent variable that can be used to predict AF.

RESUMEN

Background: Coronary artery ectasia (CAE), known for localized or diffuse excessive dilatation of the coronary artery, has an unknown etiology, but it has been reported that the underlying cause may be atherosclerosis and genetic changes that may affect the arterial lumen. MicroRNAs have been shown to have an effect in aneurysm diseases and are known to contribute to vascular development and atherosclerosis. The purpose of this study was to investigate whether they are also associated with CAE. Methods: This cross-sectional study consisted of 25 patients with CAE and 25 subjects with normal coronary arteries. Blood was collected and miRNA expression was detected using the Rotor-GeneQ real-time polymerase chain reaction cycler (Qiagen) to investigate expression levels of miR-24-1-5p, miR-34a-5p, miR-126-5p, miR-143-5p, and miR-145-5p. Results: Demographic variables of CAE (mean age 59.5 ± 1.7; 12 women) and controls (mean age 57.2 ± 2.1; 16 women) were similar. miR-126-5p (p = 0.014) and miR-145-5p (p = 0.003) levels were found to be <2-fold upregulated in CAE compared to controls; miR-143-5p also showed upregulation, but it was not significant (p = 0.078). Conversely, miR-24-1-5p (p = 0.032) levels were downregulated in CAE compared to controls. miR-34a-5p was also downregulated, but this was not considered significant (p = 0.185). Conclusions: According to our study findings, miR-126-5p, miR-145-5p, and miR-24-1-5p may be associated with CAE. These microRNAs could be of diagnostic and therapeutic significance for further studies of CAE involving abnormal angiogenesis and vascular disorders and potentially serve as useful biomarkers.

RESUMEN

OBJECTIVE: Dietary recommendations, in addition to medications, have recently become important in the treatment of heart failure. Our study aimed to show the positive effects of both milk chocolate and dark chocolate on heart failure through endothelial functions. METHODS: Twenty patients with heart failure and reduced ejection fraction were included in the study. In this randomized, crossover study, some of the patients consumed milk chocolate and some consumed dark chocolate. We recorded the patients' 6-minute walking tests, flow- mediated dilatation values, plasma catechin, epicatechin, and N-terminal pro-brain natri- uretic peptide values before and after chocolate consumption. After 2 weeks, their chocolate consumption was changed. The same parameters were measured again. RESULTS: A significant decrease was observed in N-terminal pro-brain natriuretic peptide values after consumption of both milk chocolate (356 ± 54.2 and 310 ± 72.1 pg/mL; P = .007) and dark chocolate (341 ± 57 and 301 ± 60.1 pg/mL;P=.028). Flow-mediated dilation values increased after dark chocolate consumption (8.9 ± 3% and 14 ± 4.5%; P = .019). CONCLUSION: Chocolate consumption acutely decreases N-terminal pro-brain natriuretic pep- tide values in heart failure. Dark chocolate consumption also seems to improve endothelial functions by increasing flow-mediated dilation values.

RESUMEN

OBJECTIVE: Cardiovascular diseases still play an important role in public health and epidemiol- ogy as the leading cause of death worldwide. Ischemic heart disease is the most common reason in this group. This study aims to analyze the latest trends in ischemic heart disease mor- tality rates in Turkey by age, gender, and region using the Turkish Statistical Institute mortality data and evaluate the results. METHODS: We have obtained ischemic heart disease mortality data (2009-2019, in 12 regions) for Turkey from the mortality database of the Turkish Statistical Institute. Joinpoint analysis was used to estimate the annual percentage change and average annual percentage change to identify significant changes in trends. RESULTS: The mean mortality rate for ischemic heart disease in Turkey was in an increasing trend from 2009 to 2019 (annual percentage change=1.7 (-0.8; 4.3), P=.166). This increase was more pronounced in women (annual percentage change=2.2 (-0.7; 5.2), P=.121) compared to men (annual percentage change=1.4 (-1.1; 3.9), P=.235). When the period between 2015 and 2019 was evaluated, it was determined that ischemic heart disease mortality was in a decreasing trend in the groups over 65 years of age. The death rate due to ischemic heart disease is almost 2 times higher in men than in women in Turkey, and this rate ratio is highest in the Istanbul region. CONCLUSION: Although ischemic heart disease mortality trends have decreased globally, our country's average is still on an increasing trend. However, significant decreases have been observed in ischemic heart disease mortality rates, especially in the group over 65 years of age, in the last 5 years.

RESUMEN

OBJECTIVE: Mitral valve prolapse (MVP) is the most common cause of mitral regurgitation in developed countries. The role of inflammation in the pathogenesis of MVP is still not clear. In this study, we aimed to investigate how inflammatory markers such as monocyte/high-density lipoprotein ratio (MHR), lymphocyte/monocyte ratio (LMR), neutrophil/lymphocyte ratio (NLR), and platelet/neutrophil ratio (PLR) are affected in MVP patients. METHODS: In this retrospective study, we included 461 patients with MVP and 459 normal echocardiographic patients, matched with gender and age. Inflammatory markers and all variables were compared between the two groups. RESULTS: There were no statistically significant differences in age, sex, or body mass index between the two groups. Neutrophil counts (4,960 [3,900-6,780]. 4,200 [3,800-5,600], p < 0.001), NLR (2.488 [1.72-4.51], 1.857 [1.49-2.38], p < 0.001), MHR (14.9 [11.9-18.6], 12.2 [9.4-17.3], p = 0.003), PLR (122.4 [85-171], 104.4 [85-130], p < 0.001), and CRP (0.71 ± 0.50, 0.67 ± 0.33 p < 0.001) were significantly higher, and LMR (3.75 [2.75-5.09], 4.06 [3.12-4.83] p = 0.016) was significantly lower in the MVP group than the control group, respectively. In logistic regression analysis, NLR (odds ratio [OR]: 1.058 [1.047-1.072]; p < 0.001), LMR (OR: 1.560 [1.211-2.522]; p = 0.027), and PLR (OR: 1.015 [1.012-1.019]; p = 0.003) were found to be independent predictors for MVP presence. CONCLUSIONS: These parameters can be used as a simple, low-cost, practical tool to detect inflammation in MVP.


OBJETIVO: El prolapso de la válvula mitral (MVP) es la causa más común de insuficiencia mitral en los países desarrollados. El papel de la inflamación en la patogenia del MVP aún no está claro. En este estudio, nuestro objetivo fue investigar cómo los marcadores inflamatorios como la proporción monocitos/HDL (MHR), la proporción linfocitos/monocitos (LMR), la proporción neutrófilos/linfocitos (NLR) y la proporción plaquetas/neutrófilos (PLR) se ven afectados en pacientes con MVP. MÉTODOS: En este estudio retrospectivo, incluimos a 461 pacientes con PVM y 459 pacientes ecocardiográficos normales, emparejados por sexo y edad. Se compararon los marcadores inflamatorios y todas las variables entre los dos grupos. RESULTADOS: No hubo diferencias estadísticamente significativas en edad, sexo o índice de masa corporal entre los dos grupos. El recuento de neutrófilos (4,960 [3,900-6,780], 4,200 [3,800-5,600], p < 0.001), NLR (2.488 [1.72-4.51], 1,857 [1.49-2.38], p < 0.001), MHR (14.9 [11.9-18.6]), (12.2 [9.4-17.3], p = 0.003), PLR (122.4 [85-171], 104.4 [85-130], p < 0.001) y PCR (0.71 ± 0.50, 0.67 ± 0.33 p < 0.001) fueron significativamente mayores y LMR (3.75 [2.75-5.09], 4.06 [3.12-4.83] p = 0.016) fue significativamente menor en el grupo MVP que en el grupo de control, respectivamente. En el análisis de regresión logística; NLR (OR: 1.058 [1.047-1.072]; p < 0.001), LMR (OR: 1.560 [1.211-2.522]; p = 0.027) y PLR (OR: 1.015 [1.012-1.019]; p = 0.003) se encontraron como predictores independientes para la presencia de MVP. CONCLUSIONES: Estos parámetros pueden utilizarse como una herramienta sencilla, práctica y de bajo costo para detectar la inflamación en el PVM.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the cardiac autonomic functions of individuals with asymptomatic diabetic retinopathy (DR) and no obvious heart disease by heart rate turbulence (HRT) and heart rate variability (HRV) analysis. METHODS: A total of 72 patients with type 2 diabetes mellitus: 20 non-retinopathic (NRDM), 26 non-proliferative retinopathic patients (NPDR) and 26 proliferative retinopathic patients (PDR) were enrolled in this cross-sectional study. RESULTS: The HRV parameters of Standard deviation of NN intervals (SDNN) (119.8±11.7, 101.1±20.2, 100.6±17.04), standard deviation of the average NN intervals (108.3±10.8, 91.2±17.5, 93.6±18.4), SDNN Index (49.5±5.1, 40.1±13.4, 38.6±12.7), Root mean square of successive RR interval differences (28.3±5.1, 22.3±7.5, 26±9.2) and Triangular index (34.4±4.3, 29.7±8.8, 27.3±6.7) were significantly lower in the NPDR and PDR groups than in the NRDM group (for all P<0.05). Also, there was a statistically significant higher Turbulence Onset (-1.80±0.7, -1.1±0.9, -0.43±0.81) and lower Turbulence Slope (8.05±2.59, 5.82±3.39, 4.53±2.07) in HRT parameters in patients in the NPDR and PDR groups than in the NRDM group (P<0.001). CONCLUSIONS: We found that HRV and HRT parameters had a significant deterioration in retinopathic individuals compared to the group without retinopathy. We think that HRV and HRT analysis can have an important role in the evaluation of these patients.

RESUMEN

BACKGROUND: Takotsubo Cardiomyopathy (TC) is a rare disorder that is mostly caused by stress and is often misdiagnosed. We aimed to analyze Takotsubo Syndrome at the molecular level by using the Oxford Nanopore Minion Device and its protocol. METHODS AND RESULTS: Ten patients who were previously diagnosed with Takotsubo Syndrome (increased after decrease in ejection fraction and without critical stenosis in coronary arteries) and 10 healthy individuals in the control group were included in our project. The mean age was 53 ± 12.2 for the patient group and 52.4 ± 9.9 for the control group, and the left ventricular ejection fraction was 50.3 ± 11.5 for the patient group and 64.2 ± 2.8 for the control group (p < 0.05). Peripheral blood of patients and healthy individuals was taken and their DNA was obtained. By making long reads throughout the genome, the most studied regions responsible for ß-adrenergic signaling pathways; The gene expression level of cardiac ß-1 ADRB1 (rs1801253-ENST00000369295.4), G > C, (Gly389Arg) and cardiac ß-2 ADRB2 (rs1800888-ENSG00000169252), C > T, (Thr165Ile) adrenoceptors was investigated. As a result; no structural variation was detected leading to Takotsubo Cardiomyopathy. The results obtained from the bioinformatics analysis were also checked from the VarSome Tools and similar results were found. CONCLUSIONS: Many publications in TC susceptibility have that may lead to adrenergic pathway dysregulation, most studied adrenergic receptor genes in the similar literatures too. We searched for genetic variants in b1AR and b2AR genes in our study and however we could not find any variants in this study, we think larger numbers of cohort studies are needed.

RESUMEN

INTRODUCTION: Chronic inflammation plays a considerable role in atherosclerosis and may occur simultaneously in different arteries. This condition is referred to as multisite arterial disease (MSAD). We aimed to investigate the association between inflammatory markers and MSAD. METHODS: In this cross-sectional study we included 526 patients with peripheral artery disease (PAD). Patients with PAD were evaluated by conventional or computed tomography angiography for the presence of coronary artery disease (CAD) and those with at least 30% stenosis were included in the study. Patients were divided into two groups: either MSAD+(PAD and CAD), Group 1) or MSAD- (only PAD without CAD, Group 2). Inflammatory markers were compared between the two groups. RESULTS: Among all patients, 293 had MSAD while 233 had only PAD. The MSAD+group had higher neutrophil-to-lymphocyte ratio (NLR) and platelet-to-neutrophil ratio (PLR) (5.08±0.19, 4.67±0.51, and 207.1±6.23, 169.3±10.8, respectively, p<0.001). In multivariate analysis, HT [odds ratio (OR): 2.40 (1.61-3.59)); p<0.002], male gender [OR: 2.03 (1.29-3.17); p=0.002], DM [OR:1.56 (1.03-2.36); P=0.035], NLR [OR: 1,08 (1.02-1.16); p=0.021, and PLR [OR:1.05 (1.03-1.08); p<0.001] were found to be associated with MSAD. CONCLUSION: NLR and PLR are correlated with MSAD and may indicate the extent of atherosclerosis.

RESUMEN

BACKGROUND: The CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke, vascular disease, age 65-74 years, female gender) score is used to estimate thromboembolic risk in atrial fibrillation (AF). Current studies have shown that CHA2DS2-VASc score can predict adverse clinical outcomes in coronary artery disease, stroke, and many diseases irrespective of the presence of AF. The usefulness of CHA2DS2-VASc score in predicting mortality of peripheral arterial disease (PAD) patients is unknown. In this study, we aimed to evaluate the predictive value of the CHA2DS2-VASc score for mortality of PAD patients. METHODS: A total of 396 patients diagnosed with PAD for the first time in our clinic between January 2010-July 2016 were included in this study. Patients were divided into two groups as deceased (group 1, N.=153) and living (group 2, N.=243). A ROC analysis was performed to determine if CHA2DS2VASc score could predict the death events among PAD patients. Kaplan-Meier analysis was used to evaluate the timing of death events in the two groups. RESULTS: The mean ages of group 1 and group 2 were 76.6±0.81 and 66.5±0.83 (P=0.007), respectively. The CHA2DS2VASc scores of group-1 (4.37±0.1) and group 2 (2.96±0.9) were significantly different (P<0.001). A significant correlation between CHA2DS2VASc score and death was determined in Spearman correlation (R:0.454, P<0.001). According to multivariate cox regression analysis, CHA2DS2-VASc score [odds ratio (OR): 1.81 (95% CI: 1.42-2.30); P<0.001], Stroke [OR: 0.43 (95% CI: 0.21-0.85); P=0.016] and CRP [OR: 1.04 (95% CI: 1.01-1.06); P=0.002] were independent predictors of death. CONCLUSIONS: The CHA2DS2VASc score is directly related with mortality in PAD patients. The CHA2DS2VASc score may be a useful and practical scoring method to identify high-risk patients, and further future studies are needed to assess the role of CHA2DS2VASc score in PAD.

RESUMEN

OBJECTIVE: Peripheral artery disease (PAD) is a condition caused by the narrowing of limb arteries due to atherosclerosis. In recent years, polymorphisms in a number of genes have been shown to contribute to the risk of PAD development. However, whether the contribution of these inheritable factors is independent of traditional cardiovascular risk factors remains unclear. This study was an investigation of the effects of diabetes mellitus (DM) and genetic background, examined singly and together, on the pathogenesis of PAD. METHODS: The effects of the factor V Leiden (G1691A), factor V H1299R, prothrombin G20210A, factor XIII V34L, B-fibrinogen -455 G>A, PAI-1 4G/5G, HPA1, MTHFR C677T, MTHFR A1298C, ACE I/D, APO B R3500Q, and APOE polymorphisms were evaluated using a cardiovascular disease strip assay (CVD StripAssay). Two groups were created: 100 patients with PAD (50 with DM, 50 without DM) and 60 controls without PAD (30 with DM, 30 without DM). RESULTS: There was a significantly greater presence of the MTHFR A1298C and PAI 4G/5G homozygous polymorphisms in the PAD patients compared with the control group (p=0.035, p=0.004, respectively). There were no significant associations between the other genotypes and polymorphism frequencies. In the presence of DM, the PAI-1 4G/5G homozygous polymorphism was linked to the formation of PAD (p=0.021). Regression analysis indicated that the PAI-1 4G/5G gene homozygous polymorphism demonstrated a 17.1 times greater risk for DM with PAD [95% confidence interval (CI): 2.113-138.660; p=0.008] and the MTHFR A1298C homozygous polymorphism demonstrated a 316.6 times greater risk (95% CI: 10.763-9315.342; p<0.001) for the possibility of DM with PAD. CONCLUSION: The MTHFR A1298C and PAI 4G/5G homozygous polymorphisms may be associated with the development of PAD. The presence of the PAI 4G/5G homozygous polymorphism with DM was a powerful predictor for the development of PAD.

RESUMEN

OBJECTIVE: Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation in the coronary artery lumen of at least 1.5 times the diameter of adjacent healthy reference segments. The etiology of CAE is still unknown, but the most likely cause is atherosclerosis. The aim of this study was to evaluate several gene polymorphisms that are thought to have an effect on the development of coronary atherosclerosis and have been shown to cause thrombophilia in CAE patients. METHODS: The factor V Leiden (G1691A), factor V H1299R, prothrombin G20210A, factor XIII V34L, beta-fibrinogen-455 G>A, plasminogen activator inhibitor (PAI)-1 4G/5G, and methylenetetrahydrofolate reductase (MTHFR) C677T, and MTHFR A1298C polymorphisms were evaluated in 66 patients with CAE and 32 individuals with normal coronary arteries. RESULTS: Comparison of the CAE and control groups revealed that the clinical features and the frequency of polymorphism in the thrombophilic genes were similar in both groups. However, when heterozygous and/or homozygous polymorphism was compared between groups, it was found that there was a significantly higher finding of thrombophilic gene polymorphism in the CAE group (p=0.023). CONCLUSION: Thrombophilic gene polymorphism may be associated with the formation and clinical presentation of CAE.

RESUMEN

BACKGROUND: Sudden cardiac death is the leading cause of cardiac-related death in hemodialysis patients. Hypotensive episodes in pre-, intra-, and post-dialytic periods can present serious clinical challenges that affect a patient's quality of life and prognosis. The aim of the present study was to evaluate cardiac autonomic control and arrhythmogenic risk by analyzing 24-h heart rate variability (HRV) and heart rate turbulence (HRT) in hypotensive hemodialysis patients. METHODS: A total of 79 patients on maintenance hemodialysis treatment, 39 normotensive and 40 with frequent hypotension episodes during non-dialysis periods, were included in the study. Dialysis-free periods were recorded with a 24-h Holter rhythm and ambulatory blood pressure monitor device. The time-domain parameters of HRV and HRT, including turbulence onset (TO) and turbulence slope (TS), were calculated. RESULTS: Values for SDNN (105.5 ± 7.02, 127.6 ± 6.2 p < 0.001), SDANN (95.1 ± 5.9, 111.8 ± 5.01 p < 0.001), and SDNN index (50.04 ± 2.7, 55.6 ± 3.7 p = 0.03), in the hypotensive group were significantly lower than in the normotensive group, respectively. Values for RMSSD (26.5 ± 2.5, 27.3 ± 2.7 p = 0.178), pNN50 (17 ± 1.7, 55.6 ± 3.7 p = 0.03), and TI (35.1 ± 3.1, 34.7 ± 2.6 p = 0.542) in both groups were not significantly different; however, there was a significant difference between HRT parameters, TO (- 1.8 ± 0.37, - 2.4 ± 0.39 p < 0.001) and TS (6.9 ± 0.71, 8.2 ± 0.97 p < 0.001), respectively, hypotensive and normotensive group. CONCLUSION: Dialysis patients that experience frequent hypotensive episodes may also undergo significant changes in HRT and HRV which may be indicative of serious cardiac sequela. Thus, in such cases, a complete cardiologic evaluation is warranted.

RESUMEN

AIMS: Most dilated cardiomyopathies are either an ischemic dilated cardiomyopathy (IsDC) or an idiopathic dilated cardiomyopathy (IdDC). The treatments for both IsDC and IdDC are of a similar nature (upwards of 90%). Coronary revascularization, however, is only feasible for IsDC. The purpose of this study was to determine if microRNAs (miRNAs) could be used as biomarkers to distinguish between IsDC and IdDC. MATERIALS AND METHODS: Patients were divided into two groups: IsDC and IdDC, with 25 patients in each group, and 10 healthy persons serving as a control group. In our study, the following miRNA expressions were detected using the Rotor Gene Q real-time polymerase chain reaction cycler (Qiagen) for all IsDC and IdDC subjects: let-7b-5p, let-7c-5p, miR-1-3p, miR-15b-5p, miR-17-5p, miR-19a-3p, miR-19b-3p, miR-20a-5p, miR-20b-5p, miR-23a-3p, miR-24-3p, miR-27a-3p, miR-28-5p, miR-30e-5p, miR-99b-5p, miR-100-5p, miR-101-3p, miR-103a-3p, miR-106a-5p, miR-125b-5p, miR-126-3p, miR-126-5p, miR-140-5p, miR-191-5p, miR-195-5p, miR-199a-3p, miR-214-3p, miR-222-3p, miR-342-3p, and miR-378a-3p. RESULTS: We found that miR-24-3p, miR-28-5p, miR-100-5p, miR-103-3p, miR-125b5p, miR-214-3p, let-7b-5p, and let-7c-5p were each overexpressed by more than twofold in both the IsDC and IdDC groups when compared to the controls. We also found that miR-15b-5p and miR-106a-5p may be used to distinguish between patients with IsDC and IdDC. CONCLUSIONS: Our study has demonstrated that miR-15b-5p and miR-106a-5p expression levels could potentially serve as useful biomarkers for distinguishing between IsDC and IdDC.

RESUMEN

Nasal septum deviation (NSD) can cause obstruction of the upper airway, which may lead to increased pulmonary artery pressure (PAP) and right ventricle dysfunction. The aim of the present study was to evaluate the effect of septoplasty on right ventricular function and mean PAP of patients with marked NSD. 25 patients with marked NSD (mean age = 31.8 ± 12.3 years) and 27 healthy volunteers (mean age = 34.5 ± 10.8 years) were enrolled. Echocardiography was performed for all subjects and right ventricular function and mean PAP were evaluated before and 3 months after septoplasty. Tricuspid annular plane systolic excursion (TAPSE) and tricuspid annulus early diastolic myocardial velocity (E') were significantly lower in patients with NSD than control subjects, while right ventricle myocardial performance index (RVMPI) and mean PAP were significantly higher (respectively, p = 0.006, 0.037, 0.049, 0.046). When preoperative and postoperative findings were compared, the mean PAP decreased whereas TAPSE increased significantly (respectively, p = 0.007, 0.03). The results of the present study demonstrated that mean PAP increased and right ventricular function worsened in patients with NSD. However, mean PAP decreased and right ventricular function tended to recover after septoplasty.
