Bendopnea Predicts High SYNTAX Score in Patients With Coronary Artery Disease: A Bayesian Approach.

Coronary artery disease (CAD) is one of the major health problems worldwide. CAD severity, as calculated by SYNTAX score (SS), is associated with higher morbidity and mortality. A new symptom of shortness of breath within 30 s while bending forward is described as bendopnea and is related to elevated cardiac filling pressure. It is also known that a high SS is associated with left ventricular (LV) dysfunction which leads to higher LV filling pressure. We aimed to investigate whether there was an association between bendopnea and high SS in CAD patients. A high SS was defined ≥22. Of 374 stable angina pectoris patients, 238 (64%) patients had bendopnea and 136 (36%) patients had no bendopnea in this study. The bendopnea (+) group had higher SS and Gensini scores than the bendopnea (-) group (posterior probabilities >0.999 and 0.995, respectively). The presence of bendopnea was independently associated with a higher SS (odds ratio [OR] = 3.82, 95% credible intervals [CrI] = 1.93-8.17). When different priors were used in the context of meta-analysis, there was only 18% heterogeneity among the results, indicating that the results of our study were robust. This is the first study to report that bendopnea was independently associated with CAD severity.

Development and Validation of Nomogram Based on the Systemic-Immune Inflammation Response Index for Predicting Contrast-Induced Nephropathy in ST-Elevation Myocardial Infarction Patients.

Contrast-induced nephropathy (CIN) is a prominent complication of ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (pPCI). The systemic immune inflammation response index (SIIRI) is a novel inflammatory marker developed by multiplying the monocyte count by the systemic immune inflammation index (SII) and is associated with coronary artery disease severity. We investigated the predictive ability of SIIRI for detecting CIN in STEMI patients (n = 2289) following pPCI and developed a nomogram based on SIIRI for risk stratifying. CIN was diagnosed based on an elevation in baseline creatinine levels >.5 mg/dL or 25% within 72 h after pPCI; 219 CIN (+) and 2070 CIN (-) patients were included. CIN (+) patients had higher SIIRI than CIN (-) patients and SIIRI was an independent predictor of CIN. A nomogram based on SIIRI had good calibration and discrimination abilities for predicting CIN development. SIIRI was superior to SII in discriminating CIN (+) patients. Adding SIIRI to the baseline model, which consists of age, hypertension, hemoglobin, estimated glomerular filtration rate, albumin, ejection fraction, lesion length, and pain-to-balloon time, had a higher discriminative ability and benefit in detecting CIN (+) patients than baseline model as assessed by decision curve analysis.

The association of serum uric acid/albumin ratio with the development of coronary collateral circulation in patients with chronic total occluded coronary arteries.

Introduction: Coronary collateral circulation (CCC) develops in chronic total occluded (CTO) vessels and protects the myocardium against ischemia in addition to the improvement of cardiac functions. Poor CCC is related to adverse cardiac events as well as poor prognosis. Serum uric acid/albumin ratio (UAR) has emerged as a novel marker associated with poor cardiovascular outcomes. We aimed to investigate whether there was an association between UAR and poor CCC in CTO patients. Methods: This study was comprised of 212 patients with CTO (92 with poor CCC and 120 with good CCC). All patients were graded based on Rentrop scores to poor CCC (Rentrop scores 0 and 1) and good CCC (Rentrop scores 2 and 3). Results: Poor CCC patients had higher frequencies of diabetes mellitus, triglyceride levels, Syntax and Gensini scores, uric acid, and UAR and lower lymphocyte, high-density lipoprotein cholesterol, and ejection fraction when compared to good CCC patients. UAR was an independent predictor of poor CCC in CTO patients. Furthermore, UAR had a better discriminative ability for patients with poor CCC from good CCC compared to serum uric acid and albumin. Conclusion: Based on the results of the study, the UAR could be used to detect poor CCC in CTO patients.

O Nível de Endocan Sérico pode ser Usado como Biomarcador para Prever Aterosclerose Subclínica em Pacientes Pré-Diabéticos? / Can the Serum Endocan Level Be Used as a Biomarker to Predict Subclinical Atherosclerosis in Patients with Prediabetes?

Resumo Fundamento Pacientes pré-diabéticos têm um risco aumentado de doença cardiovascular aterosclerótica, e, portanto, a detecção precoce é importante. Objetivo Nosso estudo teve o objetivo de revelar a usabilidade dos níveis de endocan sérico como biomarcador no diagnóstico de aterosclerose subclínica em pacientes pré-diabéticos, com base em medições de EIMC. Métodos Os participantes foram classificados de acordo com a presença (n=42) ou ausência (n=42) de pré-diabetes.

Resultados Apesar de se ter determinado que os níveis de endocan sérico são mais baixos em pacientes pré-diabéticos em comparação com o grupo de controle (p=0,042), determinou-se que os valores de EIMC são mais altos (p=0,046). A avaliação do endocan sérico por análise regressiva multivariada detectou que seu nível estava associado à EIMC, independentemente de outros parâmetros (p=0,007). Encontramos uma correlação negativa entre insulina plasmática em jejum e níveis de endocan (r=-0,320, p=0,001). Conclusões Este estudo demonstrou que a espessura íntima-média de carótida é mais alta e o nível de endocan sérico é mais baixo em pacientes pré-diabéticos. Os níveis de endocan sérico diminuídos em pacientes pré-diabéticos podem ser um fator que contribui para os mecanismos de formação de aterosclerose.

Abstract Background Patients with prediabetes have an increased risk of atherosclerotic cardiovascular disease; therefore, early detection is important. Objective The present study aimed to reveal the usability of serum endocan levels as a biomarker in the diagnosis of subclinical atherosclerosis in patients with prediabetes, based on CIMT measurements. Methods Participants were classified according to the presence (n=42) or absence (n=42) of prediabetes. Serum endocan, fasting blood sugar, fasting insulin, and glycated hemoglobin (HbA1c) values of patients were examined, and CIMT was measured. The level of significance for statistical analysis was 0.05. Results While serum endocan levels were found to be lower in patients with prediabetes, when compared to the control group (p=0.042), CIMT values were found to be higher (p=0.046). When evaluated by multivariate regression analysis, the serum endocan level was found to be associated with CIMT, regardless of other parameters (p=0.007). A negative correlation was found between plasma fasting insulin and endocan levels (r=-0.320, p=0.001). Conclusions Carotid intima media thickness was found to be high and the serum endocan level was low in patients with prediabetes. Decreased serum endocan levels in patients with prediabetes may be a contributing factor to atherosclerosis formation mechanisms.

Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study).

AIM: Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. METHODS: The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. RESULTS: The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 µg/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. CONCLUSION: The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management.

COVID-19 associated multisystemic inflammatory syndrome in 614 children with and without overlap with Kawasaki disease-Turk MIS-C study group.

Multisystemic inflammatory syndrome (MIS-C) diagnosis remains difficult because the clinical features overlap with Kawasaki disease (KD). The study aims to highlight the clinical and laboratory features and outcomes of patients with MISC whose clinical manifestations overlap with or without KD. This study is a retrospective analysis of a case series designed for patients aged 1 month to 18 years in 28 hospitals between November 1, 2020, and June 9, 2021. Patient demographics, complaints, laboratory results, echocardiographic results, system involvement, and outcomes were recorded. A total of 614 patients were enrolled; the median age was 7.4 years (interquartile range (IQR) 3.9-12 years). A total of 277 (45.1%) patients with MIS-C had manifestations that overlapped with KD, including 92 (33.3%) patients with complete KD and 185 (66.7%) with incomplete KD. Lymphocyte and platelet counts were significantly lower in patients with MISC, overlapped with KD (lymphocyte count 1080 vs. 1280 cells × µL, p = 0.028; platelet count 166 vs. 216 cells × 103/µL, p < 0.001). The median serum procalcitonin levels were statistically higher in patients overlapped with KD (3.18 vs. 1.68 µg/L, p = 0.001). Coronary artery dilatation was statistically significant in patients with overlap with KD (13.4% vs. 6.8%, p = 0.007), while myocarditis was significantly more common in patients without overlap with KD features (2.6% vs 7.4%, p = 0.009). The association between clinical and laboratory findings and overlap with KD was investigated. Age > 12 years reduced the risk of overlap with KD by 66% (p < 0.001, 95% CI 0.217-0.550), lethargy increased the risk of overlap with KD by 2.6-fold (p = 0.011, 95% CI 1.244-5.439), and each unit more albumin (g/dl) reduced the risk of overlap with KD by 60% (p < 0.001, 95% CI 0.298-0.559). CONCLUSION: Almost half of the patients with MISC had clinical features that overlapped with KD; in particular, incomplete KD was present. The median age was lower in patients with KD-like features. Lymphocyte and platelet counts were lower, and ferritin and procalcitonin levels were significantly higher in patients with overlap with KD. WHAT IS KNOWN: • In some cases of MIS-C, the clinical symptoms overlap with Kawasaki disease. • Compared to Kawasaki disease, lymphopenia was an independent predictor of MIS-C. WHAT IS NEW: • Half of the patients had clinical features that overlapped with Kawasaki disease. • In patients whose clinical features overlapped with KD, procalcitonin levels were almost 15 times higher than normal. • Lethargy increased the risk of overlap with KD by 2.6-fold in MIS-C patients. • Transient bradycardia was noted in approximately 10% of our patients after initiation of treatment.

Fragmented QRS in inferior leads is associated with non-alcholic fatty liver disease, body-mass index, and interventricular septum thickness in young men.

OBJECTIVE: Fragmented QRS (fQRS) has been shown to be related to coronary heart disease, heart failure, hypertension, cardiac arrhythmia, and metabolic syndrome. Although fQRS in lateral leads is shown to be associated with a poor outcome in patients with a known cardiac disease, the knowledge about the significance and prevalence of fQRS in inferior leads is scarce. This study aimed to investigate the prevalence and predictors of fQRS in inferior leads in healthy young men. METHODS: A total of 1,155 men underwent electrocardiography (ECG), hepatic ultrasonography, and routine biochemical tests. A total of 210 eligible men with fQRS in inferior leads (group 1) and 770 eligible men without fQRS in inferior leads (group 2) were compared with each other in terms of clinical, demographic, and laboratory parameters. RESULTS: The prevalence of fQRS in inferior leads was found to 21.4%. Body mass index (BMI), systolic blood pressure (BP), creatinine, and alanine aminotransferase levels; non-alcoholic fatty liver disease (NAFLD) percentage; and interventricular septum thickness (IVST) were significantly greater in group 1 than those in group 2. BMI, IVST, NAFLD, creatinine, ALT, and systolic BP were entered in a model of multiple regression analyses to predict fQRS, a dependent variable. NAFLD was the best independent predictor of fQRS (ß=6.115, p=0.001). BMI (ß=1.448, p=0.014) and IVST (ß=1.058, p=0.029) were the other independent predictors of fQRS in inferior leads. CONCLUSION: This study demonstrated the association of fQRS in inferior leads with NAFLD, BMI, and IVST in young men.

Is conventional cardiac examination adequate for obese pregnant women? A prospective case-control study.

OBJECTIVE: Obesity in pregnancy shows short- and long-term adverse effects for both mother and baby. We aimed to investigate the effects of obesity on cardiac functions in the third trimester of pregnancy. MATERIALS AND METHODS: A prospective case-control study where the pregnant women at the third trimester of pregnancy were divided into two groups: obese (BMI≥30) and the controls (BMI<30). All participants underwent conventional 2D and speckle-tracking echocardiography, while structural and functional cardiac parameters were measured. The unpaired t-test or the Mann-Whitney-U test were used to compare values between the two groups. p ≤ 0.05 was outlined to be statistically significant. RESULTS: Forty-one obese pregnant women and 41 healthy and normal-weight pregnant controls were recruited. The mean BMI was 24.6 ± 2.4 kg/m2 in the controls and 38.5 ± 5.4 kg/m2 in the obese group. SV was significantly higher in obese patients (p = 0.02). SVI was markedly lower in the obese group (p < 0.01). CO and Cardiac Index were significantly higher in obese patients compared to the controls (p < 0.01). TVRI was significantly higher in the obese group than the controls. EF was similar between the two groups (p = 0.33). LVM and LVMI were significantly higher in obese patients than the controls (p = 0.024 and p = 0.01). Diastolic dysfunction was present in 3 (7.3%) controls; 21 (51.2%) of the obese women demonstrated diastolic dysfunction, and it was significantly higher than the controls (p < 0.01). LV-GLS and LV-GCS were substantially lower in the obese group (p < 0.01). RV-FAC and RV-GS were markedly lower in the obese group (p < 0.01). TAPSE was similar in obese and control groups (p = 00.17). CONCLUSION: Obesity in pregnancy is associated with increased subclinical systolic and diastolic dysfunction, which cannot be detected by standard 2D methods.

A new biomarker that predicts ventricular arrhythmia in patients with ischemic dilated cardiomyopathy: Galectin-3.

INTRODUCTION: Ventricular arrhythmias are caused by scar tissue in patients with ischemic dilated cardiomyopathy. The gold standard imaging technique for detecting scar tissue is magnetic resonance imaging (MRI). However, MRI is not feasible for use as a screening test, and also cannot be used in patients who have received an implantable cardioverter-defibrillator (ICD). In this study, we aimed to assess the association between levels of galectin-3 (Gal-3), which is known to be secreted by scar tissue, and the history of ventricular arrhythmias in patients with ischemic dilated cardiomyopathy who received an ICD. METHODS: Nineteen healthy controls and 32 patients who had previously undergone VVI-ICD implantation due to ischemic dilated cardiomyopathy were enrolled in the study. Patients were divided into three groups: the first group including patients who had received no ICD therapies, the second including patients with arrhythmia requiring therapies with no arrhythmia storm, and the third including patients who had arrhythmia storm. We assessed the association between Gal-3 levels and the history of ventricular arrhythmias in these patients. RESULTS: Gal-3 levels were significantly higher in the patient groups than in the control group (p<0.01). Gal-3 levels of patients with arrhythmias requiring ICD therapies were significantly higher than in patients with ICD not requiring therapies (p=0.02). They were also higher in patients with a history of arrhythmia storm than in patients without shocks (p=0.05). Receiver operating curve analysis showed with 84% sensitivity and 75% specificity that Gal-3 levels over 7 ng/ml indicated ventricular arrhythmia that required therapies. CONCLUSION: Gal-3 may be used to further improve risk stratification in patients with ischemic cardiomyopathy who are more prone to developing life-threatening arrhythmias.

Can Systemic Immune-Inflammation Index Detect the Presence of Exxaggerated Morning Blood Pressure Surge in Newly Diagnosed Treatment-Naive Hypertensive Patients?

Background: The exaggerated morning blood pressure surge (MS) is associated with target organ damage and cardiovascular events. Systemic immune-inflammation index (SII) has been detected as a useful marker in tumors and cardiovascular diseases. The role of inflammation in the pathogenesis of hypertension is a well-known issue. We aimed to investigate whether there is an association between SII and exaggerated MS in newly diagnosed treatment-naive hypertensive patients.Material and Methods: In total, 343 newly diagnosed in clinical and 24-h ambulatory blood pressure (BP) monitoring treatment-naive hypertensive patients were included in this study. Morning surge was defined as the difference between morning BP, which was the mean of BP during 2 h after wake-up, and the lowest BP, which was the mean of three lowest BP during nighttime. A cutoff value of 52.1 mmHg was used to discriminate the high- and low value MS groups. SII was calculated based on neutrophil, platelet, and lymphocyte counts.Results: Neutrophil, platelet, SII, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) were higher, whereas lymphocyte counts were lower in the high-value MS than the low-value MS. These indices were all independently associated with exaggerated MS and SII was superior to all other indices for detecting the presence of exaggerated MS. SII was moderately correlated with morning BP surge (r: 0.489, p < 0.0001).Conclusion: SII was higher in patients with exaggerated MS and was independently associated with exaggerated MS. Furthermore, SII might be a better indicator than platelet, neutrophil, lymphocyte, NLR, and PLR for the presence of exaggerated MS.

Association of Mild Hyperbilirubinemia with Decreased ECG-Based Ventricular Repolarization Parameters in Young Men.

OBJECTIVE: Hyperbilirubinemia is associated with protection against various oxidative stress-mediated diseases. We aimed to investigate the association between bilirubin and novel electrocardiography (ECG)-based ventricular repolarization parameters. METHODS: We enrolled 201 healthy men with mild hyperbilirubinemia (group 1) and 219 healthy men with normal bilirubin levels (group 2). The Tpeak-Tend (Tp-e) interval (defined as the interval from the peak of the T wave to the end of the T wave), corrected (c) Tp-e interval, QT interval, cQT interval, and Tp-e interval/QT interval ratio were measured from leads V5 and V6 with 20 mm/mV amplitude and 50 mm/second rate. RESULTS: The Tp-e interval, cTp-e interval, and Tp-e interval/QT interval ratio were significantly lower in group 1 compared with group 2. The cTp-e interval showed a significant negative correlation with total bilirubin, conjugated bilirubin, and unconjugated bilirubin. The cTp-e interval (odds ratio [OR], 0.900; P =.002) and Tp-e interval/QT interval ratio (OR, 0.922; P =.04) were significantly associated with mild hyperbilirubinemia. CONCLUSION: We showed the association of mild hyperbilirubinemia with decreased novel ECG-based ventricular repolarization parameters.

Multilayer global longitudinal strain assessment of subclinical myocardial dysfunction related to insulin resistance.

Myocardial tissue is sensitive to insulin resistance (IR) due to its interactions with insulin levels. Previous studies demonstrated that heart failure prevalence was higher in IR patients. Evaluation of myocardial deformation by multilayer global longitudinal strain (MGLS) might provide more information about IR related left ventricular dysfunction. In this study, we aimed to investigate subclinical LV dysfunction with MGLS in patients with IR. The study was designed as a prospective cross-sectional study. The present study included 64 patients with IR (+), and 54 subjects without IR (-) prospectively. The homeostasis model of insulin resistance (HOMA-IR) was used to quantify insulin resistance. Specific analysis for endocardial, mid-myocardial and epicardial layers were performed by two-dimensional (2D) speckle tracking echocardiography (STE) for multilayer global longitudinal strain. MGLS (Endocard-Mid-myocard-Epicard) values were significantly lower in the IR (+) group compared to IR (-) group ((GLS-endocard; - 15.1 ± 1.5 vs. - 18.7 ± 1.3, p < 0.001), (GLS-mid-myocard; - 16.0 ± 2.0 vs. - 18.0 ± 2.0, p < 0.001), (GLS-epicard; - 17.0 ± 1.7 vs. - 18.01 ± 1.94, p = 0.004)). GLS-endocard levels were significantly and positively correlated with HOMA-IR levels (r = 0.643, p < 0.001). HOMA-IR and age were found to be independent factors in detecting a decrease in GLS-endocard level in regression analysis. In conclusion, our data reveal that IR (+) patients had significantly lower strain values compared to IR (-) group. Besides, we presented that the HOMA-IR value was an independent predictor of subclinical left ventricular dysfunction.

Short and Midterm Outcomes in Patients With Acute Myocardial Infarction: Results of the Nationwide TURKMI Registry.

This recent Turkish Myocardial Infarction registry reported that guidelines are largely implemented in patients with acute myocardial infarction (MI) in Turkey. We aimed to obtain up-to-date information for short- and midterm outcomes of acute MI. Fifty centers were selected using probability sampling, and all consecutive patients with acute MI admitted to these centers (between November 1 and 16, 2018) were enrolled. Among 1930 (mean age 62 ± 13 years, 26% female) patients, 1195 (62%) had non-ST segment elevation myocardial infarction (NSTEMI) and 735 (38%) had ST segment elevation myocardial infarction (STEMI). Percutaneous coronary intervention (PCI) was performed in 94.4% of patients with STEMI and 60.2% of those with NSTEMI. Periprocedural mortality occurred in 4 (0.3%) patients. In-hospital mortality was significantly higher in STEMI than in patients with NSTEMI (5.4% vs 2.9%, respectively; P = .006). However, the risk became slightly higher in the NSTEMI group at 1 year. Women with STEMI had a significantly higher in-hospital mortality compared with men (11.2% vs 3.8%; P < .001); this persisted at follow-up. In conclusion, PCI is performed in Turkey with a low risk of complications in patients with acute MI. Compared with a previous registry, in-hospital mortality decreased by 50% within 20 years; however, the risk remains too high for women with STEMI.

The relationship between clinical characteristics and psychological status and quality of life in patients with vasovagal syncope.

OBJECTIVE: Syncope is characterized by sudden and short-term loss of postural tone and consciousness. Vasovagal syncope (VVS) episode is usually self-limiting, and it may affect patients' quality of life. In this study, we aimed to investigate the relationship between quality of life, Beck-depression and Beck-anxiety scales and clinical characteristics of the VVS patients. METHODS: The present study included 88 patients with VVS. Tilt table test was performed to all the patients. Patients filled out the Quality of life, Beck-depression, and Beck-anxiety scale forms. Demographics, medical history, echocardiography, blood pressures, electrocardiography and physical examination findings were recorded. RESULTS: There was a significant and negative correlation between the total syncope episodes (TSE) and EQ-5D index and EQ-5D-VAS index, respectively (p<0.001, r: -0.649; p<0.001, r: -0.587). TSE was significantly and positively correlated with the Beck-anxiety scale and Beck-depression scale. EQ-5D index, EQ-5D-VAS index, Beck-depression scale, and Beck-anxiety scales were defined as an independent predictor of TSE in VVS patients. CONCLUSION: Psychological factors play an essential role in VVS patients. EQ-5D index, EQ-5D-VAS index, Beck-depression, and Beck-anxiety scales were an independent predictor of the TSE in patients with VVS.

The prevalence and correlates of T-wave inversion in lead III in non-obese men.

BACKGROUND: T-wave inversion in lead III was linked to displacement of the base of the heart due to abdominal adipose tissue in early electrocardiography (ECG) trials. The observation of T-wave inversion in lead III in some of the pathological and physiological conditions other than obesity suggests the possibilities of different mechanisms. We aimed to investigate the prevalence and correlates of T-wave inversion in lead III in non-obese men. METHOD: A total of 1240 men underwent ECG, blood pressure measurement, hepatic ultrasonography, and biochemical tests from January 2019 to December 2019. We excluded 220 subjects due to predetermined criteria. The eligible 105 non-obese men with T-wave inversion in lead III and 915 non-obese men without T-wave inversion in lead III were compared with each other in terms of clinical, demographic and laboratory parameters. RESULTS: The mean age was 27.9 years with a range of 20 to 46 years. The prevalence of T-wave inversion in lead III was 10.3%. Body mass index (BMI), blood urea nitrogen, creatinine, alanine aminotransferase, hematocrit, and the percentage of non-alcoholic fatty liver disease (NAFLD) were significantly higher in Group with T-wave inversion while alkaline phosphatase was significantly higher in Group without T-wave inversion. In multivariable analysis, NAFLD was the best independent correlate of inverted T-wave in lead III (ß = 6.215, p < 0.0001). BMI (ß = 1.448, p < 0.001) and hematocrit (ß = 1.179, p = 0.021) were the other independent correlates of T-wave inversion in lead III. CONCLUSION: We demonstrated the association of T-wave inversion in lead III with NAFLD, BMI, and hematocrit in non-obese men.

[Can biomarkers help us to understand the pathogenesis of coronary slow flow? Endocan and omentin-I in slow coronary flow phenomenon]. / Biyobelirteçler koroner yavas akim patogenezini anlamamiza yardimci olabilir mi? Koroner yavas akim fenomeninde endokan ve omentin-I.

OBJECTIVE: The pathophysiology of the slow coronary flow (SCF) phenomenon is still unclear. The two most frequently cited mechanisms of SCF are endothelial dysfunction and subclinical diffuse atherosclerosis. The aim of this study was to investigate the relation of SCF to serum endocan levels which is associated with endothelial dysfunction and to serum omentin-I levels which is associated with atherosclerosis. METHODS: A total of 42 patients with SCF and 43 controls with normal coronary flow based on a coronary angiogram were enrolled. Serum endocan and omentin-I levels were measured and the presence of SCF was determined according to Thrombolysis in Myocardial Infarction frame count (TFC) calculations. RESULTS: The omentin-I level was significantly lower and the endocan level was significantly higher in patients with SCF than in the controls. Receiver operating characteristic curve analysis revealed that the sensitivity and specificity of endocan for SCF was 66% and 70%, respectively (area under the curve [AUC]: 0.760, 95% confidence interval [CI]: 0.65-0.86; p<0.001), and the comparable values for omentin were 66% and 61% (AUC: 0.630, 95% CI: 0.51-0.75; p=0.049). Multivariate logistic regression analysis revealed that a high endocan level (odds ratio [OR]: 6.8, 95% CI: 1.849-2.439, cutoff: 2.45 ng/mL; p=0.003) and a low omentin-I level (OR: 3.6, 95% CI: 1.057-12.893, cutoff: 4.63 ng/mL; p=0.041) were independently associated with the presence of SCF. In patients with SCF, the endocan level was positively correlated with the mean TFC, while the omentin-I level was negatively correlated (r=0.44; p<0.001 and r=-0.22; p=0.049, respectively). CONCLUSION: These results revealed that endocan and omentin-I might be useful biomarkers for predicting the presence and severity of SCF.

Evaluation of the left venticular systolic function with the measurement of global longitudinal strain by Speckle tracking echocardiography in anaphylaxis.

BACKGROUND: It is not known how cardiac functions are affected during anaphylaxis. OBJECTIVE: Our aim was to measure the cardiac functions shortly after an anaphylaxis attack using a new technique that detects subclinical left ventricular dysfunction. METHODS: Patients in our hospital who experienced anaphylaxis and urticaria (control group) due to any cause were included in the study. Tryptase levels were measured on the third hour of the reaction and 6 weeks later. Left ventricular systolic functions were evaluated with global strain measurement using echocardiography, approximately 4 hours and 6-week post reaction. RESULTS: Twelve patients were included in the anaphylaxis group (83.3% female; mean age, 43.25 ± 9.9 years). The causes of anaphylaxis were drug ingestion (n = 11) and venom immunotherapy. Eight of the anaphylactic reactions (66.7%) were severe and in 9 reactions (75%) tryptase levels increased. In the anaphylaxis group, strain values measured shortly after anaphylaxis were significantly lower than those calculated 6 weeks later (p < 0.001) and tryptase levels significantly increased (p = 0.002). The strain values measured both shortly after anaphylaxis and 6 weeks later did not differ according to severity of anaphylaxis. In severe anaphylaxis, tryptase levels during anaphylaxis and 6 weeks later were significantly higher (p = 0.019, p = 0.035). The control group evidenced no differences regarding strain and tryptase levels measured at reaction and 6 weeks later. At reaction, in the anaphylaxis group, the tryptase levels were higher and the strain values were lower than those in the urticaria group (p = 0.007, p = 0.003). CONCLUSION: Cardiac dysfunction may develop during an anaphylaxis independent of severity of reaction.
