Turkish Real Life Atrial Fibrillation in Clinical Practice: TRAFFIC Study.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes. METHODS: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons. RESULTS: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023. CONCLUSION: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.

Functional impact of cardiac implanted devices on ipsilateral shoulder range of motion, scapular mobility, and self-reported quality of life.

PURPOSE: Shoulder disorders may occur for procedural reasons in patients fitted with a cardiac implantable electronic device (CIED). This study aimed to examine the effects of CIED implantation on shoulder functions and scapular dyskinesis. MATERIALS AND METHODS: Thirty patients fitted with a CIED formed the study group (SG), whilst 30 participants without a CIED formed the control group (CG). The range of motion (ROM), grip strength, lateral scapular slide test (static), scapular dyskinesis test (dynamic), American Shoulder and Elbow Surgeons (ASES) Shoulder Score, and the Short Form-36 Health Survey (Physical and Mental Component Summary [PCS and MCS]) were applied in the study. RESULTS: The shoulder's mean flexion and abduction ROM on the implant side were found to be significantly lower in the SG than the CG (p = .016 and p = .001, respectively). Similarly, a significant grip strength loss on the implant side was detected in the SG than in the CG (p = .036). Static and dynamic scapular dyskinesis frequencies were shown to be significantly higher in the SG than in the CG (p = .002 and p< .001, respectively). The ASES Shoulder Score and PCS score were significantly lower in the SG than in the CG (p = .014 and p = .007, respectively). However, no difference was revealed between the two groups with respect to the contralateral upper limb. CONCLUSION: The frequency of scapular dyskinesis and disability was higher, and upper limb functions, grip strength, and physical subdivision of quality of life decreased in CIED recipients. These findings suggest that such parameters should be included in physiotherapy assessment and treatment programs.

Real-World Evaluation of Anticoagulant Treatment Patterns in Patients with Atrial Fibrillation: Data from Multicenter ROTA Study.

OBJECTIVE: Oral anticoagulant therapy is the cornerstone of atrial fibrillation management to prevent stroke and systemic embolism. However, there is limited real-world information regarding stroke and systemic embolism prevention strategies in patients with atrial fibrillation. The aim of the ROTA study is to obtain the real-world data of anticoagulant treatment patterns in patients with atrial fibrillation. METHODS: The ROTA study is a prospective, multicenter, and observational study that included 2597 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January 2021 and May 2021. RESULTS: The median age of the study population was 72 years (range: 22-98 years) and 57.4% were female. The median CHA2DS2-VASc and HAS-BLED scores were 4 (range: 0-9) and 1 (range: 0-6), respectively. Vitamin K antagonists and direct oral anticoagulants were used in 15.9% and 79.4% of patients, respectively. The mean time in therapeutic range was 52.9% for patients receiving vitamin K antagonists, and 76% of those patients had an inadequate time in therapeutic range with <70%. The most common prescribed direct oral anticoagulants were rivaroxaban (38.1%), apixaban (25.5%), and edoxaban (11.2%). The rate of overuse of vitamin K antagonists and direct oral anticoagulants was high (76.1%) in patients with low stroke risk, and more than one-fourth of patients on direct oral anticoagulant therapy were receiving a reduced dose of direct oral anticoagulants. Among patients who were on direct oral anticoagulant treatment, patients with apixaban treatment were older, had higher CHA2DS2-VASc and HAS-BLED scores, and had lower creatinine clearance than the patients receiving other direct oral anticoagulants. CONCLUSIONS: The ROTA study provides important real-world information about anticoagulant treatment patterns in patients with atrial fibrillation.time in therapeutic range with <70%.

Evaluation of aortic stiffness by echocardiography in tympanosclerosis patients.

BACKGROUND AND AIMS: Tympanosclerosis (TS) is a scarring process that may occur during otitis media. Aortic stiffness (AS) is a significant predictor for the development of heart diseases due to its close relationship with atherosclerosis. Similar pathophysiological processes based on inflammation may explain both TS and AS formation. This study aimed to determine echocardiographically whether aortic elasticity is impaired in TS-detected patients and to correlate blood inflammatory parameters with TS and aortic elasticity. METHODS: Ninety-eight participants diagnosed with chronic otitis media were enrolled in the study. TS-detected 42 participants were assigned to the study group, while 56 without TS constituted the control group. The two groups' demographic, clinical, echocardiographic, and laboratory characteristics were comparable. RESULTS: Demographic, clinical, and laboratory parameter differences were insignificant. Hs-CRP, neutrophil-to-lymphocyte ratio, and systemic immune-inflammation index were significantly higher in the study group than in the control group (P=0.018, P=0.003, P=0.019, respectively). The study group had significantly lower aortic strain (11.80 ± 4.84 vs. 16.30 ± 3.91; P<0.001) and distensibility (5.23 ± 2.68 vs. 7.24 ± 2.89; P=0.001) values than the control group. The AS index was significantly higher in the study group than in the control group (4.81 ± 2.41 vs. 3.12 ± 1.02; P<0.001). CONCLUSION: In TS-detected patients, AS parameters were found to be impaired. Aortic elasticity parameters measured by echocardiography, a non-invasive and easily accessible method, may signify early cardiovascular involvement in TS-developed patients.

Relationship between CIED extent of displacement toward the shoulder while in the supine position and shoulder impairment.

BACKGROUND: Device-related shoulder impairment is a common complication in cardiac implantable electronic device (CIED) recipients. This study examined the relationship between the extent of device displacement toward the shoulder while in the supine position and ipsilateral shoulder impairment. METHODS: This cross-sectional study included 142 consecutive patients with CIEDs. The effects of the extent of device displacement on functional limitations, muscle strength, pain-disability, and quality of life were evaluated. Range of motion (ROM), grip strength (GS), the Shoulder Pain and Disability Index (SPADI), and the 36-item Short-Form (SF-36) Health Survey were used. RESULTS: The mean device displacement was greater in patients with than without device-related shoulder impairment (51 ± 19 vs. 38 ± 15 mm; p < .001). Female gender (p = .046), high body mass index (p = .008), and defibrillator implantation (p = .004) were significantly more frequent in patients with than without impairment. Patients with excessive device displacement had significantly higher ROM limitation rates (p = .003) and SPADI scores (p = .02) and significantly lower GS (p = .04) and SF-36 scores (p = .032). Defibrillator implantation (OR: 2.569, 95% CI: 1.216-4.681; p = .03) and the extent of device displacement (OR: 1.502, 95% CI: 1.186-1.852; p = .01) were independent predictors of shoulder impairment. CONCLUSIONS: Excessive displacement of the device toward the shoulder while in the supine position causes shoulder impairment by contacting more muscle fibers. Obese female patients with defibrillators have the highest risk.

The preventive effect of exogenous adenosine triphosphate on methanol-induced cardiotoxicity in rats

Abstract Exposure to methanol can cause serious consequences such as permanent visual disturbances and death. The heart tissue is highly vulnerable to ATP deficiency. Our study aimed to investigate whether exogenous ATP administration may alleviate methanol-induced ATP deficiency and subsequent oxidative damage in rat heart tissue. A total of 30 rats were divided into equal five groups; Healthy Group (HG), Methotrexate (MXG), Methanol (MeOH), Methotrexate+Methanol (MXM), and Methotrexate+Methanol+ATP (MMA) groups. We inhibited tetrahydrofolate synthesis by methotrexate to induce methanol toxicity. Methotrexate was administered to MXG, MXM, and MMA group animals for seven days with a catheter directly to the stomach at a 0,3 mg/kg dose per day. At the end of this period, % 20 methanol at a dose of 3 g/kg was administered to MeOH, MMA and MXM group animals. Immediately after methanol application, MMA group animals were injected with ATP at a 4 mg/kg dose intraperitoneally. Blood samples and heart tissues were used for biochemical analysis and histopathological examination. Co-exposure to methanol and methotrexate substantially exacerbated cardiac damage, indicating the potent cardiotoxic effects of methanol. However, the administration of exogenous ATP to MMA group animals brought biochemical oxidative damage parameters and histopathological findings closer to HG.

PrevAleNce and Associated factors of inappropriaTe dosing of direct Oral anticoaguLants In pAtients with Atrial Fibrillation: the ANATOLIA-AF Study.

PURPOSE: Inappropriate dosing of direct oral anticoagulants is associated with an increased risk of stroke, systemic embolism, major bleeding, cardiovascular hospitalization, and death in patients with atrial fibrillation. The main goal of the study was to determine the prevalence and associated factors of inappropriate dosing of direct oral anticoagulants in real-life settings. METHODS: This study was a multicenter, cross-sectional, observational study that included 2004 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January and May 2021. The main criteria for inappropriate direct oral anticoagulant dosing were defined according to the recommendations of the European Heart Rhythm Association. RESULTS: The median age of the study population was 72 years and 58% were women. Nine-hundred and eighty-seven patients were prescribed rivaroxaban, 658 apixaban, 239 edoxaban, and 120 dabigatran. A total of 498 patients (24.9%) did not receive the appropriate dose of direct oral anticoagulants. In a logistic regression model, advanced age, presence of chronic kidney disease and permanent atrial fibrillation, prescription of reduced doses of direct oral anticoagulants or edoxaban treatment, concomitant use of amiodarone treatment, and non-use of statin treatment were significantly associated with potentially inappropriate dosing of direct oral anticoagulants. CONCLUSION: The study demonstrated that the prevalence of inappropriate direct oral anticoagulant dosing according to the European Heart Rhythm Association recommendations was 24.9% in patients with atrial fibrillation. Several demographic and clinical factors were associated with the inappropriate prescription of direct oral anticoagulants.

Myringosclerosis as a predictor of the requirement for a permanent pacemaker in patients with drug-related atrioventricular block.

AIMS: Drug-related atrioventricular block (DR-AVB) may develop in patients with underlying latent degenerative conduction disorders, especially with antiarrhythmics and antihypertensives. Although, according to the current guidelines, reversal is achieved with cessation of the inducing agent, this is not the case for nearly half of the patients. The pathophysiological processes of DR-AVB and myringosclerosis include systemic inflammation and degeneration. This study investigated the role of myringosclerosis in predicting irreversible high-grade DR-AVB despite drug cessation. METHODS: This observational, non-randomized, prospective study involved 152 patients with high-grade DR-AVB, 72 of whom had reversible DR-AVB and 80 had irreversible DR-AVB and required permanent pacemakers. The patients' demographic, clinical, echocardiographic, and laboratory characteristics were recorded. Otoscopic tympanic membrane examinations for myringosclerosis were performed. RESULTS: There were no major differences in demographic, echocardiographic or laboratory characteristics between the two groups or previous medications. The median monitoring time with a temporary pacemaker was significantly longer in the irreversible than in the reversible group (5 [4-7] days vs. 2 [1-5] days; P<0.001). The incidence of myringosclerosis was significantly higher in the irreversible than in the reversible group (61.3% vs. 22.2%; P=0.001). Multivariate logistic regression analysis showed that myringosclerosis was an independent predictor of irreversible DR-AVB (odds ratio: 1.703, 95% confidence interval: 1.194-3.058; P=0.01). CONCLUSION: Myringosclerosis is a readily available, inexpensive, and non-invasive assessment and is a marker of inflammation and degeneration that can predict irreversible DR-AVB.

Efficacy and safety of different exercises in preventing cardiac implantable electronic device-related shoulder impairment.

BACKGROUND: Shoulder impairment on the implant side is common after cardiac implantable electronic device (CIED) implantation. The aim of this study was to compare the efficacy and safety of the pendulum exercise (PE) and stretching and strengthening exercises (SSE) in preventing postimplantation shoulder impairment. METHODS: This prospective, randomized study collected data from 89 patients, including 30 in a control group, 31 in a PE group, and 28 in an SSE group. Shoulder functions on the implant side were evaluated by grip strength (GS), range of motion (ROM), Visual Analog Scale (VAS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), and 36-Item Short-Form Survey (SF-36). RESULTS: Shoulder median flexion and abduction ROM were significantly improved 2-month postimplantation compared to two-week postimplantation in PE (156 ± 11 vs. 146 ± 10, p = .002; 147 ± 9 vs. 136 ± 9, p = .001, respectively) and SSE (158 ± 13 vs. 147 ± 11, p = .003; 149 ± 13 vs. 138 ± 9, p = .002, respectively) groups, but not in the control group. Two months after implantation, the two exercise groups showed no significant differences in any assessment. Compared with the PE and SSE groups, the control group had significantly lower GS (p = .012 and p = .002, respectively) and SF-36 physical component summary (p = .007 and p = .003, respectively) and significantly higher VAS (p = .003 and p = .001, respectively) and QuickDASH (p = .002 and p = .005, respectively) scores 2-month postimplantation. CONCLUSIONS: PE and SSE for the ipsilateral upper arm starting two-week after CIED implantation provided similar benefits in preserving shoulder girdle muscle strength, maintaining shoulder motion, relieving shoulder pain, preventing shoulder injury, and improving quality of life, without the risk of lead dislodgement.

The preventive effect of taxifolin on acrylamide-induced heart damage in rats / O efeito preventivo da taxifolina em danos cardíacos induzidos por acrilamida em ratos

ABSTRACT Objective Acrylamide is a toxic compound widely used in industrial sectors. Acrylamide causes reactive oxygen species formation and the subsequent lipid peroxidation reaction, which plays an important role in the pathogenesis of oxidative damage. Taxifolin is a flavonoid with antioxidant properties that inhibit reactive oxygen species formation. In this study, we aimed to investigate the preventive effect of taxifolin on acrylamide-induced oxidative heart damage. Methods The rats were divided into three groups: Acrylamide, Acrylamide+Taxifolin , and Healthy group. Water and food intake and body weight alterations were recorded daily. Malondialdehyde, total glutathione, nuclear factor kappa-B, total oxidant status, and total antioxidant status levels were analyzed from the heart tissue. Troponin-I levels, the parameter known as a cardiac biomarker, were analyzed from the blood sample. The cardiac histopathologic examination was also performed. Results In the Acrylamide group animals, the malondialdehyde, nuclear factor kappa-B, total oxidant status, and troponin-I levels were significantly higher compared to the ones of Acrylamide+Taxifolin and Healthy groups. The levels of total glutathione and total antioxidant status were significantly lower compared to Acrylamide+Taxifolin and Healthy groups'. Additionally, in the Acrylamide group, body weight gain, food and water intake, significantly declined compared to the Acrylamide+Taxifolin and Healthy groups. However, in the Acrylamide+Taxifolin group, taxifolin supplementation brought these values close to Healthy group ones. Furthermore, taxifolin treatment ameliorated structural myocardial damage signs induced by acrylamide. Conclusion Acrylamide exposure significantly induced oxidative damage to rat heart tissue. Taxifolin was able to improve the toxic consequences of acrylamide biochemically and histopathologically, possibly due to its antioxidant properties.

RESUMO Objetivo A acrilamida é um composto tóxico amplamente utilizado em setores industriais. Ela causa a formação de reativas de oxigênio e subsequente reação de peroxidação lipídica, que desempenham um papel importante na patogênese do dano oxidativo. A taxifolina é um flavonóide com propriedades antioxidantes que inibe a formação de reativas de oxigênio. Neste estudo, o objetivo foi investigar o efeito preventivo da taxifolina no dano cardíaco oxidativo induzido por acrilamida. Métodos Os ratos foram divididos em três grupos: Acrilamida, Acrilamida+Taxifolina e grupo Saudável. Ingestão de água e comida e alterações de peso corporal dos animais foram registradas diariamente. Malondialdeído, glutationa total, fator nuclear kappa-B, estado oxidante total e estado antioxidante total foram analisados no tecido cardíaco dos ratos. Os níveis de troponina-I, - parâmetro conhecido como biomarcador cardíaco, foram analisados a partir de amostra de sangue. Um exame histopatológico cardíaco também foi realizado. Resultados Nos animais do grupo Acrilamida, os níveis de malondialdeído, fator nuclear kappa-B, estado oxidante total e troponina-I foram significativamente maiores em comparação com os do grupo Acrilamida+Taxifolina e Saudável. Os níveis de glutationa total e estado antioxidante total foram significativamente mais baixos em comparação com grupos Acrilamida+Taxifolina e Saudável. Além disso, no grupo Acrilamida, o ganho de peso corporal e a ingestão de alimentos e água diminuíram significativamente em comparação com os animais dos grupos Acrilamida+Taxifolina e Saudável. No entanto, no grupo Acrilamida+Taxifolina, a suplementação com taxifolina aproximou esses valores aos do grupo Saudável. Além disso, o tratamento com taxifolina melhorou os sinais de dano miocárdico estrutural induzidos pela acrilamida. Conclusão A exposição à acrilamida induziu significativamente o dano oxidativo do tecido cardíaco dos ratos. A taxifolina foi capaz de melhorar as consequências tóxicas da acrilamida bioquímica e histopatologicamente, possivelmente devido às suas propriedades antioxidantes.

Bilirubin levels as an independent predictor of myocarditis in patients with COVID-19.

BACKGROUND: Myocardial damage worsens the clinical course and prognosis of coronavirus disease 2019 (COVID-19) patients. High total bilirubin levels have been associated with a poor prognosis in COVID-19. This study aimed to investigate the predictive value of the total bilirubin level, a marker of heme oxygenase-1 enzyme activity, in determining myocarditis in patients with COVID-19. RESULTS: A total of 190 patients diagnosed with COVID-19 were enrolled in the study. The patients were divided into two groups based on their troponin positivity. The study group (n = 95) consisted of patients with high troponin, and the control group (n = 95) consisted of patients without high troponin levels. The D-dimer (727 [572-995] vs. 591 [440-790], p = 0.001), C-reactive protein (CRP) (30.0 [10-48] vs. 10.3 [5.8-15.9], p < 0.001), and total bilirubin (9.5 [8.2-12.1] vs. 7.0 [5.3-8.0], p < 0.001) levels were significantly higher in the study group. In multivariate analysis, CRP (odds ratio [OR]: 1.103; 95% confidence interval [CI]: 1.060-1.148; p < 0.001) and total bilirubin (OR: 1.612; 95% CI: 1.330-1.954; p < 0.001) levels were independent predictors of myocarditis in COVID-19. CONCLUSIONS: Total bilirubin levels can be used as an early predictor of myocarditis in COVID-19 and can contribute to therapy management.

Predictors of shoulder limitations and disability in patients with cardiac implantable electronic devices: Importance of device size.

BACKGROUND: Generator-induced shoulder impairment is a common complication of cardiac implantable electronic device (CIED) implantation. Although implantable cardioverter-defibrillators (ICDs) have become smaller in size, they are still bigger than pacemakers (PMs). This study aimed to investigate the effects of single-chamber PM and ICD sizes on shoulder function. METHODS: This retrospective study included 200 consecutive patients, of whom 123 had PMs and 77 had ICDs. The CIED implantation effects on shoulder function, pain, disability, and quality of life (QoL) were evaluated. The range of motion (ROM), Visual Analog Scale (VAS), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), and Short Form-36 (SF-36) Health Survey (Physical and Mental Component Summary [PCS and MCS]) were used. RESULTS: The flexion and abduction range limitation rates were significantly higher in the ICD group than in the PM group (16.9% vs. 7.3%, p = .035 and 19.5% vs. 8.9%, p = .031, respectively). The two groups had similar VAS scores. The median QuickDASH score was significantly higher in the ICD group than in the PM group (8.2 [3.6-19.6] vs. 4.6 [2.6-17.9], p = .034). There were no significant differences in SF-36 components between the two groups. ICD implantation (OR: 1.642, 95% CI: 1.293-2.776; p = .001) and incision length (OR: 1.343, 95% CI: 1.194-2.064; p = .01) were independent predictors of shoulder ROM limitations. CONCLUSIONS: Reduced device sizes with advancing technology can decrease shoulder functional limitations and disability after implantation. Healthcare professionals should not neglect shoulder evaluations during the pre- and postimplantation periods.

Predictors of left atrial remodeling in newly diagnosed hypertensive patients: a speckle-tracking echocardiographic study.

Endothelial dysfunction, oxidative stress, and increased inflammatory activity are the main pathophysiological mechanisms responsible for cardiac remodeling secondary to hypertension. Bilirubin has anti-oxidant, anti-inflammatory, and anti-fibrotic functions. This report's objectives are to determine whether Query identifiers of left atrial (LA) remodeling, total atrial conduction time (TACT) and LA reservoir strain (LARS), are associated with serum total bilirubin levels, and to identify the possible predictors of LA remodeling in newly diagnosed hypertensive subjects. One hundred thirty-four subjects were enrolled in this study. TACT was evaluated by tissue Doppler imaging, and LARS was calculated by speckle-tracking echocardiography. Laboratory parameters were recorded. The subjects were classified into two separate groups according to the median value of TACT and LARS. In patients with supramedian TACT, LA volume index (LAVI) and epicardial adipose tissue (EAT) thickness were higher, while LARS and LVGLS were lower. In subjects with inframedian LARS, TACT was longer, LAVI and EAT thickness were higher, and LVGLS was lower. Patients with supramedian TACT and inframedian LARS were older and had lower total bilirubin. Total bilirubin, EAT thickness, and age were predictors of TACT and LARS. Serum bilirubin levels may have a protective effect on the LA remodeling process in newly diagnosed hypertensive subjects.
