Effect of Hand Dominance on Radial Artery Spasm and Occlusion: A Prospective Observational Study.

Transradial access has become the most commonly used method for cardiac catheterization. Many medical and technical applications have been proposed to reduce TRA complications. The aim of this study is to examine the effect of hand dominance on radial artery spasm and radial artery occlusionin subjects undergoing CC via TRA. Between April 2020 and August 2022, 1713 subjects who underwent CC via TRA were included in the study. Patient data were obtained in terms of hand dominance of the catheterized side and RAS and RAO during a 1-month follow-up period. RAS was seen in 9.6% of the subjects. The RAS in patients catheterized by the dominant hand was significantly higher than that performed by the non-dominant hand (12 vs 7.8%; P = .004). RAO was seen in 1% of the subjects. RAO was significantly higher in the spasm side than in the no-spasm side (3 vs .8%; P = .009). Hand dominance was determined as an independent predictor of radial artery spasm (P = .006). In our study, RAS and RAO were more common on the dominant hand side than on the non-dominant side. Choosing the non-dominant hand for TRA for CC may reduce the incidence of RAS and RAO.

Could Zonulin and Presepsin Be Biomarkers and Therapeutic Targets for Acute Myocarditis? / Zonulina e Presepsina Poderiam ser Biomarcadores e Alvos Terapêuticos para Miocardite Aguda?

BACKGROUND: The diagnosis of acute myocarditis is usually made with clinical and laboratory parameters. This can sometimes be mixed up with diseases that have similar clinical features, making the diagnosis difficult. Therefore, the use of more specific biomarkers, in addition to the classically used biomarkers such as troponin, will accelerate the diagnosis. In addition, these biomarkers may help us to understand the mechanism of myocarditis development and thus predict unpredictable clinical outcomes. OBJECTIVE: This study aims to reveal the possible relationship between intestinal permeability and acute myocarditis. METHODS: In this study, we wanted to evaluate serum levels of zonulin and presepsin in 138 consecutive subjects, including 68 patients with myocarditis and another 70 as the control group, matched for age, gender, and cardiovascular risk factors. P-values <0.05 were considered to be statistically significant. RESULTS: Compared to the control group, zonulin and presepsin were significantly higher in the patient group with myocarditis (p < 0.001, for all). Zonulin levels were positively correlated with presepsin, peak CK-MB, and peak troponin levels (r = 0.461, p < 0.001; r = 0.744, p < 0.001; r = 0.627, p < 0.001; respectively). In regression analysis, presepsin and zonulin were determined as independent predictors for myocarditis (OR 1.002, 95% CI 1.001-1.003, p = 0.025; OR 12.331, 95% CI 4.261-35.689; p < 0.001; respectively). The predictive value of acute myocarditis of presepsin and zonulin in ROC curve analysis was statistically significant (p < 0.001, for both). CONCLUSION: This study showed that zonulin and presepsin could be biomarkers that can be used in the diagnosis of myocarditis, and they can also be therapeutic targets by shedding light on the developmental mechanism of myocarditis.

FUNDAMENTO: O diagnóstico de miocardite aguda geralmente é feito diante de parâmetros clínicos e laboratoriais, podendo, por vezes, ser confundido com doenças que compartilham de características clínicas semelhantes, o que dificulta o diagnóstico. Sendo assim, o uso de biomarcadores mais específicos, para além dos clássicos como a troponina, acelerará o diagnóstico. Além disso, esses biomarcadores podem nos ajudar a compreender melhor o mecanismo de desenvolvimento da miocardite e, assim, prever resultados clínicos imprevisíveis. OBJETIVO: Este estudo tem como objetivo revelar a possível relação entre permeabilidade intestinal e miocardite aguda. MÉTODOS: Neste estudo, buscamos avaliar os níveis séricos de zonulina e presepsina em 138 indivíduos consecutivos, incluindo 68 pacientes com miocardite e outros 70 usados como grupo controle, pareados por idade, sexo e fatores de risco cardiovascular. Valores de p < 0,05 foram considerados estatisticamente significativos. RESULTADOS: Em comparação com o grupo controle, zonulina e presepsina foram significativamente maiores no grupo de pacientes com miocardite (p < 0,001, para todos). Os níveis de zonulina foram positivamente correlacionados com presepsina, pico de CK-MB e níveis máximos de troponina (r = 0,461, p < 0,001; r = 0,744, p < 0,001; r = 0,627, p < 0,001; respectivamente). Na análise de regressão, presepsina e zonulina foram determinadas como preditores independentes para miocardite (OR de 1,002, IC de 95% 1,001-1,003, p = 0,025; OR de 12,331, IC de 95% 4,261-35,689; p < 0,001; respectivamente). O valor preditivo de miocardite aguda de presepsina e zonulina na análise da curva ROC foi estatisticamente significativo (p < 0,001, para ambos). CONCLUSÃO: Este estudo mostrou que a zonulina e a presepsina podem ser biomarcadores para o diagnóstico de miocardite e também podem ser alvos terapêuticos para esclarecer o mecanismo de desenvolvimento da miocardite.

Investigation of the Relationship Between Triglycerides-Glucose Index and Coronary Slow Flow: A Retrospective Case-Control Study. / Investigação da Relação entre Índice de Triglicerídeos-Glicose e Fluxo Lento Coronariano: Um Estudo Retrospectivo de Caso-Controle.

BACKGROUND: Coronary slow flow (CSF) refers to delayed distal vessel opacification in the absence of epicardial coronary artery stenosis. The etiopathogenic mechanism of CSF is still unclear. OBJECTIVES: This study investigates the relationship between CSF and the triglyceride-glucose (TyG) index. METHODS: The study sample consisted of 118 CSF patients and 105 patients with normal coronary flow (NCF). The coronary flow rate was measured via the Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) method in all patients. The TyG index was calculated as the logarithm of the [fasting triglyceride (mg/dL)×fasting glucose (mg/dL)]/2 value. A significance level of < 0.05 was adopted as statistically significant. RESULTS: The TyG index, low-density lipoprotein (LDL), body mass index (BMI), neutrophil-to-lymphocyte ratio (NLR) and TFC values, male ratio, and the ratio of smokers were higher, whereas high-density lipoprotein (HDL) levels were significantly lower in the CSF group compared to the NCF group (p<0,05). The correlation analysis revealed that CSF was significantly correlated with TyG index, BMI, NLR, and HDL values. The strongest of these correlations was between CSF and TyG index (r= 0.57, p<0.001). Additionally, the multivariate analysis revealed that TyG index, BMI, NLR ratio, and male gender were independent predictors for CSF (p<0.05). Receiver operating characteristic (ROC) curve analysis indicated that a cut-off value of ≥ 9.28 for the TyG index predicted CSF with a sensitivity of 78% and a specificity of 78.1% [Area under the curve (AUC): 0.868 and 95% Confidence Interval (CI): 0.823-0.914]. CONCLUSION: The findings of this study revealed a very strong relationship between CSF and TyG index.

FUNDAMENTO: O fluxo lento coronariano (FLC) refere-se à opacificação retardada dos vasos distais na ausência de estenose da artéria coronária epicárdica. O mecanismo etiopatogênico do FLC ainda não está claro. OBJETIVOS: Este estudo investiga a relação entre o FLC e o índice de triglicerídeos-glicose (TyG). MÉTODOS: A amostra do estudo consistiu de 118 pacientes com FLC e 105 pacientes com fluxo coronariano normal (FCN). A taxa de fluxo coronariano foi medida por medio do método de contagem de quadros (TFC) Thrombolysis in Myocardial Infarction (TIMI) em todos os pacientes. O índice TyG foi calculado como o logaritmo do valor [triglicerídeos em jejum (mg/dL)×glicose em jejum (mg/dL)]/2. Adotou-se como estatisticamente significativo o nível de significância < 0,05. RESULTADOS: O índice TyG, lipoproteína de baixa densidade (LDL), índice de massa corporal (IMC), relação neutrófilo-linfócito (RNL) e valores de TFC, proporção masculina e proporção de fumantes foram maiores, enquanto os níveis de lipoproteína de alta densidade (HDL) foram significativamente menores no grupo FLC em comparação com o grupo FNC (p<0,05). A análise de correlação revelou que o FLC estava significativamente correlacionado com os valores do índice TyG, IMC, RNL e HDL. A mais forte dessas correlações foi entre o FLC e o índice TyG (r= 0,57, p<0,001). Além disso, a análise multivariada revelou que o índice TyG, IMC, razão RNL e sexo masculino foram preditores independentes para FLC (p<0,05). A análise da curva ROC (Receiver Operating Characteristic) indicou que um valor de corte ≥ 9,28 para o índice TyG previu FLC com sensibilidade de 78% e especificidade de 78,1% [Área sob a curva (AUC): 0,868 e 95% intervalo de confiança (IC): 0,823-0,914]. CONCLUSÃO: Os achados deste estudo revelaram uma relação muito forte entre o FLC e o índice TyG.

Increased whole blood viscosity is associated with primary idiopathic complete atrioventricular block and poor clinical outcomes in these patients.

BACKGROUND: Complete atrioventricular block is most commonly caused by age-related degeneration and fibrosis in the cardiac conduction system and is called primary idiopathic complete atrioventricular (iCAVB). Although many factors affect this situation, which increases with age in the cardiac conduction system, the relationship between whole blood viscosity (WBV) and iCAVB has not been clarified until now. In this study, we aim to reveal the relationship between iCAVB and WBV. METHODS AND RESULTS: 141 patients with dual-chamber permanent pacemaker implanted for iCAVB and 140 age- and sex-matched subjects were included in this study. The WBV values of the study groups were compared in both high shear rate (HSR) and low shear rate (LSR). Both WBV at HSR and WBV at LSR were significantly higher in the iCAVB group compared to the control group (16.11 [15.14-16.89] vs 14.40 [13.62-15.58]; 39.82 [17.43-55.23] vs 1.38 [-13.14-26.73]; p < 0.001, respectively). The patient population was followed up for an median of 38 months for all-cause mortality. Higher mortality rates were found in higher WBV at HSR and WBV at LSR (p < 0.001,for both). CONCLUSIONS: In this study, WBV was found to be an independent predictor for iCAVB, and in these patients WBV was associated with poor clinical outcomes.

Ectodysplasin A is associated with the presence and severity of coronary artery disease and poor long-term clinical outcome in patients presenting with ST-elevation myocardial infarction.

OBJECTIVES: Hepatokines are proteins secreted by hepatocytes and many hepatokines such as fetuin A/B, selenoprotein P have been shown to play a role in the pathogenesis of many metabolic dysfunctions such as diabetes, insulin resistance, hypertension, and metabolic syndrome by showing autocrine, paracrine and systemic effects. Ectodysplasin A (EDA) is a recently discovered hepatokine that plays a role in the development of ectodermal structures. In recent studies, it has been revealed that EDA may be associated with the pathogenesis of non-alcoholic liver disease, insulin resistance, Type 2 diabetes mellitus. The close relationship between these metabolic diseases and coronary artery disease (CAD), which may be associated with insulin resistance, has been well documented in previous studies. However, until now, there is no study examining the relationship of EDA with CAD and its effect on long-term outcomes. In this study, we aim to reveal this relationship on patients presenting with ST elevation myocardial infarction (STEMI). METHODS: EDA levels of 544 patients who applied to the study with STEMI and 544 people without coronary artery disease were included in the control group, and the patients with STEMI were followed for median of 33.7 ± 6.8 months. RESULTS: We found that EDA levels were significantly higher in patients with STEMI and that EDA levels were proportional to the severity of CAD (p < 0.001) also EDA levels may be an independent predictor of poor clinical outcome in patients with STEMI. CONCLUSION: These results suggest that EDA is closely related to the presence and severity of CAD.

SCUBE1 is associated with thrombotic complications, disease severity, and in-hospital mortality in COVID-19 patients.

INTRODUCTION: COVID-19 disease, which has recently become an important cause of mortality and morbidity all over the world, is remarkably associated with thrombotic complications. Although many factors are responsible for these increased thrombotic complications in COVID-19 disease, its relationship with a marker that increases the risk of thrombosis such as Signal peptide-CUB-EGF domain-containing protein 1 (SCUBE1) has not yet been clarified. This is the first study to examine the potential diagnostic and prognostic value of SCUBE1 levels in patients with COVID-19. In this study, we aimed to clarify the relationship between the increased risk of thrombosis and SCUBE1 in the course of COVID-19 disease. MATERIALS AND METHODS: 553 patients with COVID-19 and 553 healthy controls were compared in terms of SCUBE1 levels. Additionally, patients with COVID-19 were divided into two groups according to their SCUBE1 levels and compared in terms of severity of disease, thrombotic complications and in-hospital mortality. RESULTS: SCUBE1 levels were significantly higher in patients with COVID-19 compared to the control group (p < 0.001). Plasma SCUBE1 levels were significantly higher in patients with severe disease and thrombotic complications, those with mild to moderate disease, and those without thrombotic complications (p < 0.001, for both). In addition, SCUBE1 was found to be an independent predictor of in-hospital mortality (p < 0.001). CONCLUSIONS: SCUBE1 may be one of the major determinants of thrombotic complications, which is an increased cause of mortality and morbidity in COVID-19 patients so inhibition of this peptide may be among the therapeutic targets in patients with COVID-19.

The Impact of C-Peptide and Diabetes Mellitus on Coronary Ectasia and Effect of Coronary Ectasia and C-Peptide on Long-Term Outcomes: A Retrospective Cohort Study.

Background: Coronary artery ectasia (CAE) is an entity frequently associated with atherosclerotic coronary artery disease (CAD) in clinical practice. Although it has common risk factors with atherosclerotic CAD in its development, the pathophysiology of CAE is not fully known and it is not seen in every CAD suggesting that different determinants may play a pivotal role in the development of CAD. This study aimed to reveal the impact of C-peptide and diabetes mellitus (DM) on CAE and the effect of C-peptide and coronary ectasia on long-term outcomes in patients who underwent coronary angiography. Methods: A total of 6611 patients who underwent coronary angiography were followed up retrospectively, and their major adverse cardiovascular event (MACE) status of an average of sixty months was recorded. According to their angiographic features, the patients were divided into two groups those with and without CAE. MACE development was accepted as the primary endpoint. Results: A total of 552 patients had CAE and MACE developed in 573 patients. Patients with CAE and higher C-peptide levels (Q4 + Q3) showed higher rates of MACE as compared to those without CAE and lower C-peptide levels (Q1 + Q2) (20.8% vs 7.6%; 70.1% vs 29.1%; p < 0.001, for both of them). In multivariate regression analysis, high C-peptide levels were determined as an independent risk factor for CAE (OR 2.417; 95% CI 2.212-2.641; p < 0.001). The Kaplan-Meier cumulative survival curves showed that the risks for MACE increased as the C-peptide levels increased. The Cox regression analysis for 5-years MACE related to the plasma C-peptide levels and presence of CAE, C-peptide, and CAE were found to be independent predictors of MACE (HR = 1.255, 95% CI: 1.164-1.336, p < 0.001 and HR = 1.012, 95% CI: 1.002-1.023, p=0.026, respectively). Conclusion: Our study revealed that a high C-peptide level is an independent risk factor for CAE and that CAE and C-peptide are independent predictors for the development of MACE.

The Triglyceride-Glucose Index Can Predict Long-Term Major Adverse Cardiovascular Events in Turkish Patients With High Cardiovascular Risk.

Objective: There is an evidence gap regarding the predictive accuracy of the triglyceride-glucose (TyG) index for long-term major adverse cardiovascular events (MACEs) in individuals with high cardiovascular risk. The aim of this investigation was to evaluate the predictive value of the TyG index for long-term MACEs in patients at high cardiovascular risk. Methods: In total, 483 patients with high cardiovascular risk were included in this analysis. The study population was separated into 2 groups depending on the occurrence of long-term MACEs. The independent predictors of long-term MACEs in patients with high cardiovascular risk were investigated. The long-term prognostic value of the TyG index in these patients was evaluated in terms of MACEs. Results: Age, male sex, diabetes mellitus, and the TyG index were demonstrated to be independent predictors of long-term MACE occurrence in patients with high cardiovascular risk. The TyG index was independently related to long-term MACEs in patients with high cardiovascular risk (hazard ratio, 1.003; 95% confidence interval [CI], 1.001-1.006; p=0.011). The receiver operating characteristic curve revealed that the optimum value of the TyG index to predict long-term MACEs in the overall study cohort was >9.68, with 65% sensitivity and 63% specificity (area under the curve, 0.71; 95% CI, 0.65-0.77; p<0.001). Conclusion: The TyG index was demonstrated to be an independent predictor of long-term MACE occurrence in patients with high cardiovascular risk who had not been previously diagnosed with cardiovascular disease.

Performance of the Academic Research Consortium High Bleeding Risk Criteria in Patients With ST-Segment Elevation Myocardial Infarction: A Single Center Study.

We assessed the ability of predicting mortality and total in-hospital bleeding and adverse outcomes by the Academic Research Consortium High Bleeding Risk (ARC-HBR) criteria in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). A total of 1441 STEMI patients were recruited: HBR group 354 (25%) patients and non-HBR group of 1087 (75%) patients. A total of 131 patients (9%) had a bleeding complication during hospitalization. The bleeding complications were also categorized according to other conventional bleeding scores. According to these conventional scores, all bleeding categories were associated with HBR. In univariate logistic regression analysis, female gender, diabetes mellitus, hypertension (HT) and HBR were associated with in-hospital bleeding. However, in multivariable analysis only HT (Odds Ratio [OR] 1.528, 95% CI 1.020-2.290; P = .040) and HBR (OR 1.612, 95% CI 1.075-2.428; P = .022) independently predicted total in-hospital bleeding complications. Hospital duration was longer and mortality rate was significantly higher in patients with HBR (OR 8.755, 95% CI 5.864-13.074; P < .01). The ARC-HBR criteria may predict in-hospital bleeding events and adverse outcomes in STEMI patients undergoing pPCI.

Endocarditis-TR: Diagnosis, treatment, and prognosis of the infective endocarditis patients admitting tertiary centres of Turkey.

BACKGROUND: Infective endocarditis (IE) is still a significant cause of morbidity and mortality among cardiovascular diseases. ENDOCARDITIS-TR study aims to evaluate the compliance of the diagnostic and therapeutic methods being used in Turkey with current guidelines. METHODS: The ENDOCARDITIS-TR trial is a multicentre, prospective, observational study consisting of patients admitted to tertiary centres with a definite diagnose of IE. In addition to the demographic, clinical, microbiological, and echocardiographic findings of the patients, adverse events, indications for surgery, and in-hospital mortality were recorded during a 2-year time interval. RESULTS: A total of 208 IE patients from 7 tertiary centres in Turkey were enrolled in the study. The study population included 125 (60.1%) native valve IE (NVE), 65 (31.3%) prosthetic IE (PVIE), and 18 (8.7%) intracardiac device-related IE (CDRIE). One hundred thirty-five patients (64.9%) were culture positive, and the most frequent pathogenic agent was methicillin-susceptible Staphylococcus aureus (MSSA) (18.3%). Among 155 (74.5%) patients with an indication for surgery, only 87 (56.1%) patients underwent surgery. The all-cause mortality rate was 29.3% in-hospital follow-up. Multivariable Cox regression analysis revealed that absence of surgery when indicated (HR: 3.29 95% CI: 0.93-11.64 p = 0.05), albumin level at admission (HR: 0.46 95% CI: 0.29-0.73 P < 0.01), abscess formation (HR: 2.11 95% CI: 1.01-4.38 p = 0.04) and systemic embolism (HR: 1.78 95% CI: 1.05-3.02 p = 0.03) were ascertained independent predictors of in-hospital all-cause mortality. DISCUSSION: The short-term results of the ENDOCARDITIS-TR trial showed the high frequency of staphylococcal IE, relatively high in-hospital mortality rates, shortage of surgical treatment despite guideline-based surgical indications and low usage of novel imaging techniques. The results of this study will provide a better insight to physicians in respect to their adherence to clinical practice guidelines.

The relation between average 1-year home blood pressure and the change in pro-BNP and left ventricle mass index.

BACKGROUND: The purpose of this investigation was to examine the association between average 1-year home blood pressure and the change in left ventricular mass index (LVMI) and pro-brain natriuretic peptide (BNP) levels. METHODS: This prospective study was a subgroup analysis of lifestyle intervention using mobile technology in patients with high cardiovascular risk: a pragmatic randomized clinical Trial (LIGHT). In total, 242 patients were stratified into tertiles according to their average 1-year home blood pressure. RESULTS: Patients grouped into the tertile 3 (T3) had a lower 1-year mean, SBP and DBP. The T3 group had a 2.1 times higher rate of decrease in pro-BNP and a 1.6 times higher rate of decrease in LVMI compared with T1, compared with the reference group. The area under curve (AUC) value of average 1-year home blood pressure was higher than that of mean SBP or DBP. (AUC, 0.75 vs. AUC, 0.70 vs. AUC, 0.69, respectively). Spearman rank correlation demonstrated that average 1-year home blood pressure had a correlation with Δpro-BNP and ΔLVMI. CONCLUSION: The present study showed that average 1-year home blood pressure may have a significant association with a decrease in LVMI and pro-BNP. Our study appears to be the first to evaluate the association between average 1-year home blood pressure and the change in LVMI and pro-BNP.
