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. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

- Abstract
Aims: We aimed to determine the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and to identify clinical factors associated with their use in patients with heart failure (HF) in a real-life setting., Methods: Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study is a multicentre, cross-sectional and observational study that included HF patients in the outpatient setting regardless of ejection fraction from 19 cardiology centres between August 2023 and December 2023., Results: The study population consisted of 1923 patients with HF, predominantly men (61.2%), with a median age of 66 (range: 19-101) years. Overall, 925 patients (48.1%) were receiving SGLT2is. Among the study population, 22.1% had HF with preserved ejection fraction, 21.5% had HF with mildly reduced ejection fraction, 56.4% had HF with reduced ejection fraction and the use of SGLT2is was 42.0%, 47.9% and 50.6% in each group, respectively (P = 0.012). The use of SGLT2is was 76.6% in patients with HF and diabetes, 19.8% in patients with HF and chronic kidney disease and 26.8% in patients without diabetes and chronic kidney disease (P < 0.001). Higher education level [odds ratio (OR): 1.80; 95% confidence interval (CI): 1.06-3.05; P = 0.027], higher household income (OR: 3.46; 95% CI: 1.27-9.42; P = 0.015), New York Heart Association functional class IV (OR: 2.72; 95% CI: 1.16-6.35; P = 0.021), diabetes (OR: 9.42; 95% CI: 6.72-13.20; P < 0.001), the use of angiotensin receptor-neprilysin inhibitors (ARNis) (OR: 4.09; 95% CI: 2.39-7.01; P < 0.001), the use of mineralocorticoid receptor antagonists (MRAs) (OR: 2.02; 95% CI: 1.49-2.75; P < 0.001), the use of loop diuretics (OR: 1.62; 95% CI: 1.18-2.22; P = 0.003) and the use of thiazide diuretics (OR: 1.72; 95% CI: 1.30-2.29; P < 0.001) were independently associated with the use of SGLT2is. Conversely, atrial fibrillation (OR: 0.63; 95% CI: 0.45-0.88; P = 0.008), chronic kidney disease (OR: 0.53; 95% CI: 0.37-0.76; P = 0.001), the use of dihydropyridine calcium channel blockers (OR: 0.68; 95% CI: 0.48-0.98; P = 0.042) and the use of statins (OR: 0.67; 95% CI: 0.49-0.91; P = 0.010) were independently associated with the non-use of SGLT2is., Conclusions: The RED-HEART study provided comprehensive real-world data about implementing SGLT2is in patients with HF. These results suggest that there is a need for organized action and close collaboration between healthcare providers to improve the implementation of SGLT2is, especially in patients with HF with preserved ejection fraction and chronic kidney disease., (© 2024 The Author(s).

- Abstract
Background/Objectives : As an endocrine organ, adipose tissue produces adipokines that influence coronary artery disease (CAD). The objective of this study was to assess the potential value of CTRP5 and chemerin in differentiating coronary computed tomography angiography (CCTA)-confirmed coronary artery disease (CAD) versus non-CAD. Secondarily, within the CCTA-confirmed CAD group, the aim was to investigate the relationship between the severity and extent of CAD, as determined by coronary artery calcium score (CACS), and the levels of CTRP5 and chemerin. Methods : Consecutive individuals with chest pain underwent CCTA to evaluate coronary artery anatomy and were divided into two groups. The CCTA-confirmed CAD group included patients with any atherosclerotic plaque (soft, mixed, or calcified) regardless of calcification, while the non-CAD group consisted of individuals without plaques on CCTA, with zero CACS, and without ischemia on stress ECG. Secondarily, in the CCTA-confirmed CAD group, the severity and extent of CAD were evaluated using CACS. Blood samples were collected and stored at -80 °C for analysis of CTRP5 and chemerin levels via ELISA. Results : Serum CTRP5 and chemerin levels were significantly higher in the CAD group compared to the non-CAD group (221.83 ± 103.81 vs. 149.35 ± 50.99 ng/mL, p = 0.003 and 105.02 ± 35.62 vs. 86.07 ± 19.47 ng/mL, p = 0.005, respectively). Receiver operating characteristic (ROC) analysis showed that a CTRP5 cutoff of 172.30 ng/mL had 70% sensitivity and 73% specificity for identifying CAD, while a chemerin cutoff of 90.46 ng/mL had 61% sensitivity and 62% specificity. A strong positive correlation was observed between CTRP5 and chemerin, but neither adipokine showed a correlation with the Agatston score, a measure of CAD severity and extent, nor with coronary artery stenosis as determined by CCTA. Conclusions : CTRP5 and chemerin were significantly elevated in the CCTA-confirmed CAD group compared to the non-CAD group, with CTRP5 showing greater sensitivity and specificity. However, neither adipokine was linked to CAD severity and extent, differing from findings based on invasive coronary angiography (ICA). CTRP5 may serve as a promising "all-or-none biomarker" for CAD presence.

- Abstract
Objective: The main objective of this study is to determine the incidence and predictors of clinical outcomes in patients with AF treated with factor Xa inhibitors in a real-world setting., Methods: The present study was a multicentre and observational study that included patients with AF who were treated with factor Xa inhibitors. The primary outcome was the composite of ischemic stroke, TIA, systemic embolism, major bleeding, and all-cause mortality., Results: A total of 1162 patients from 26 cardiology centers were included in this study, with a median age of 72 years. During the median 12-month follow-up period, the primary outcome occurred in 195 patients (16.8%). Treatment with rivaroxaban compared with apixaban and edoxaban showed a lower rate of ischemic stroke, TIA, and/or systemic embolism (2.2% vs. 4.7% vs. 6.5%, respectively, p = 0.014). The major bleeding rate was similar between all three factor Xa inhibitors. The all-cause mortality rate in the rivaroxaban group was lower compared with the apixaban and edoxaban groups (9.8% vs. 15.1% vs. 12.4%, respectively, p = 0.042). Overall, the frequency of primary outcome was 13.8%, 19.6%, and 20.6% for patients treated with rivaroxaban, apixaban, and edoxaban, respectively (p = 0.019). Older age, male sex, low body weight, high bleeding risk, heart failure, hypertension, liver failure, and treatment with apixaban 2.5 mg b.i.d. were independently associated with the development of primary outcome., Conclusion: The follow-up data from the ANATOLIA-AF study provides detailed data about the incidence and independent predictors of adverse clinical outcomes in patients with AF treated with factor Xa inhibitor treatment., (© 2025 The Author(s).

- Abstract
Objective: Integrating heart failure (HF) guideline recommendations into clinical practice takes time and is often suboptimal in real-life settings. Physician-related factors may be significant barriers to the adoption of these guidelines. This survey aims to assess the current opinions of cardiologists practicing in Türkiye regarding the management of heart failure with reduced ejection fraction (HFrEF)., Methods: The survey comprised 22 questions and was published on the SurveyMonkey platform., Results: A total of 177 cardiologists (mean age: 39.5 years; 73.3% male) participated in the survey. Of these, 38.7% worked in a training and research hospital, and 10.2% were specialists in HF. The threshold EF value to define HFrEF was ≤ 40% for 80.1% of the cardiologists. While 52.6% of physicians considered angiotensin receptor-neprilysin inhibitor (ARNi) treatment the most effective medication for HF, 62.7% would initiate HF treatment with an angiotensin-converting enzyme inhibitor (ACEi) instead of ARNi due to reimbursement and cost issues. More than half of the cardiologists (52.3%) stated that adding another class of HF medication is more important than up-titrating those already prescribed. Although 69.5% of the study participants indicated prescribing all four classes of HF medications during the initial hospitalization is feasible, most cardiologists preferred a sequential approach starting with ACEi/ARNi, followed by beta-blockers, mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter 2 inhibitors (SGLT2i)., Conclusion: This survey highlights significant discrepancies between guideline recommendations and the real-life clinical practice of cardiologists in Türkiye. These results suggest that there is a need for organized action by healthcare providers to improve the implementation of guideline recommendations.

- Abstract
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%.

- Abstract
Background: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort., Methods: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded., Results: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%., Conclusion: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

- Abstract
Objective: This study aimed to evaluate whether the addition of heart rate-corrected QT inter- val prolongation to the Global Registry of Acute Coronary Events risk score improves the pre- dictive value for early mortality in patients with non-ST segment elevation acute coronary syndrome., Methods: We retrospectively screened our database for consecutive non-ST-segment eleva- tion acute coronary syndrome patients between January 2017 and July 2019. The demographic and clinical parameters were acquired via chart review. All electrocardiograms were reviewed by 2 physicians. QT interval was measured using the tangent method. Early mortality was defined as all-cause death observed during the hospital stay or within 30 days after discharge., Results: The final study population consisted of 283 patients, there were 17 early deaths. Ten of 59 patients with prolonged corrected QT intervals died (16.9%, P < .001). Both the Global Registry of Acute Coronary Events risk score (odds ratio: 1.032; 95% CI: 1.012-1.053; P = .002) and corrected QT interval (odds ratio: 1.026; 95% CI: 1.007-1.045; P = 0.007) independently predicted early mortality. The area under value was 0.769 (95% CI: 0.674-0.863, P < .001) for the corrected QT interval and 0.780 (95% CI:0.681-0.878; P < .001) for the Global Registry of Acute Coronary Events risk score alone. However, when the corrected QT interval and the Global Registry of Acute Coronary Events risk score were combined, it was found to be 0.808 (95% CI: 0.713-0.904, P < .001)., Conclusion: This study is the first to report that prolonged corrected QT and the Global Registry of Acute Coronary Events risk score independently predict early mortality and a combina- tion of these 2 factors may improve the predictive value for early mortality in patients with ST-segment elevation acute coronary syndrome.

- Abstract
Objectives: To assess the impact of low-flow, mid-flow, and high-flow sevoflurane anesthesia on the oxidative state by measuring thiol/disulfide levels in patients undergoing surgery., Methods: The study included 99 patients randomly assigned to 3 groups. In the low-flow anesthesia group, the fresh gas flow was diminished to 1 L.min
-1 for anesthesia maintenance after 6 L.min-1 was administered for the first 10 minutes. In the mid-flow anesthesia group, fresh gas flow was applied as 2 L.min-1 . In the high-flow anesthesia group, the fresh gas flow was administered as 4 L.min-1 throughout the operation. Blood samples were obtained before induction, at the 60th minute after induction, and at 2 hours postoperatively. Native thiol, total thiol, disulfide analyzed and disulfide/native thiol percentage, disulfide/total thiol percentage, and native thiol/total thiol percentage were calculated., Results: Disulfide values in mid-flow and low-flow anesthesia were significantly lower at the 60th minute after induction compared to the high-flow anesthesia group. In the group evaluations, intraoperative native thiol levels in the high-flow group were found to be substantialy lower than preoperative values., Conclusion: It was sighted that low-flow anesthesia with sevoflurane prohibited oxidative damage. It was concluded that low flow anesthesia can be utilized safely in this respect., (Copyright: © Saudi Medical Journal.)- Published

- Abstract
Objective: The D-SPIRIT registry is designed to investigate the safety and effectiveness of dabigatran etexilate in patients with atrial fibrillation in routine clinical practice., Methods: D-SPIRIT is the first national, multicenter, prospective, observational, postmarketing registry that investigates the usage of dabigatran in real life. A total of 326 noveloral anticoagulant-eligible patients with atrial fibrillation who have been taking dabigatran etexilate therapy for stroke prevention at least 6 months from 9 different centers were enrolled into the registry. Patients were followed up for 2 years to evaluate the effectiveness and safety of the treatment. All adverse clinical events including bleeding, thromboembolic events, stroke, systemic embolism, transient ischemic attack, myocardial infarction, and all-cause death were recorded., Results: The mean age was 71.1±9.6 years, and 57.4% of the study participants were female. The mean CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke or transient ischemic attack [TIA], vascular disease, age 65-74 years, sex category) score was 3.4±1.6. The cumulative adverse clinical events rate was 6.30% per year. The rate for embolic events including TIA, ischemic stroke, and peripheral embolism was 1.26% per year. The rate for major bleeding was 2.20% per year, and the mortality rate was 0.94% per year., Conclusion: This registry obtained an important overview of the current safety and effectiveness of the dabigatran etexilate in Turkey. Our results indicate similar rates of thromboembolic and bleeding events with pivotal phase 3 trial and other real-life registries. However, rate of undertreatment usage of dabigatran etexilate in real life was found to be considerable.

- Abstract
Background: The aim of this study was to detect the optimal values for Age, Body Mass Index (BMI) and HOMA-IR of obese patients prior to surgery that results in a maximal decrease of visceral fat mass 6 months after bariatric surgery., Method: In this study, 3
3 experimental set-ups were designed. This study was approved by Baskent University Medical and Health Sciences Research Board (Approval number: KA16/281). The study data consisted of 40 obese patients who lost weight through the bariatric surgery between February 2015 and December 2016. The values of BMI, Age and HOMA for the obese patients who lost weight through the bariatric surgery were evaluated in three categories and at three levels; the response variable was determined as the Change in Epicardial Fat Thickness (ΔEFT)., Results: As a result of CCD analysis, the optimum ΔEFT = 2.571 was determined when Age = 30.52, BMI = 45.30, and HOMA = 34.62. As a result of the BBD analysis, the optimum ΔEFT = 3.756 was determined, when Age = 38.36, BMI = 63.18, and HOMA = 14.95. The optimum ΔEFT was modeled with Contour and Response Surface plots., Conclusion: Based on the two surface response models used in our study, the maximal decrease of visceral fat mass as assessed by measuring echography images of epicardial fat thickness can be obtained by bariatric surgery of persons who are between 31 and 38 year old, have a BMI between 45 and 63 kg/m2 and have a HOMA-IR 34 between 15 and 35. Central Composite Design and a Box-Behnken Design of suitable patient data predicted 35 optimal settings of independent variables for the maximal clinical response of an intervention., Competing Interests: The authors declare there are no competing interests., (©2021 Elmalıet al.)- Published

- Abstract
Objective: Heart failure (HF) is a growing public health problem with high morbidity and mortality. Recently, angiotensin receptor neprilysin inhibitor (ARNi) has emerged as a promising treatment for HF with reduced ejection fraction (HFrEF). Here, we shared our experience with the use of ARNi in HFrEF from multiple centers in Turkey., Methods: The ARNi-TR is a multicenter, noninterventional, retrospective, observational study. Overall, 779 patients with HF from 22 centers in Turkey who were prescribed sacubitril/valsartan were examined. Initial clinical status, biochemical and echocardiographic parameters, and New York Heart Association functional class (NYHA-FC) values were compared with follow-up values after 1 year of ARNi use. In addition, the effect of ARNi on number of annual hospitalizations was investigated, and the patients were divided into 2 groups, depending on whether ARNi was initiated at hospitalization or under outpatient clinic control., Results: N-terminal pro-brain natriuretic peptide (NT-proBNP), left-ventricle ejection fraction (LV-EF), and NYHA-FC values improved significantly in both groups (all parameters, p<0.001) within 1-year follow-up. In both groups, a decrease in hemoglobin A1c (HbA1c) values was observed in ARNi use (p<0.001), and a decrease in daily diuretic doses and hospitalizations owing to HF were observed after ARNi use (all comparisons, p<0.001). Hypotension (16.9%) was the most common side effect in patients using ARN., Conclusion: The ARNi-TR study offers comprehensive real-life data for patients using ARNi in Turkey. The use of ARNi has shown significant improvements in FC, NT-proBNP, HbA1c levels, and LV-EF. Likewise, reductions in the number of annual hospitalizations and daily furosemide doses for HF were seen in this study.

- Abstract
We report the case of a 52-year-old female diagnosed with Brugada syndrome (BrS) scheduled to undergo right total knee arthroplasty. General anaesthesia was induced and maintained with thiopental intravenous sodium + remifentanil and sevoflurane + remifentanil infusion, respectively. Rocuronium bromide was used as the muscle relaxant. The defibrillator was ready for use with the electrodes on the patient. Sugammadex was used for muscle relaxant antagonization. Postoperative analgesia was provided by intermittent morphine HCL via an epidural catheter, intravenous patient-controlled analgesia (Meperidine), and intravenous tenoxicam. The patient was discharged on the 6th day without any problem. Anaesthetic management of patients with BrS is challenging for anaesthesiologists, because fatal cardiac arrhythmias can be triggered by many drugs commonly used in the perioperative period such as bupivacaine, lidocaine, neostigmine, propofol, succinylcholine, ketamine, and tramadol. In these cases, a detailed preoperative evaluation including family history, avoidance of drugs triggering arrhythmia, taking precautions against arrhythmia, and using the agents that are reported to be safe are essential for patient safety., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (© Copyright 2021 by Turkish Anaesthesiology and Intensive Care Society.)

- Abstract
Purpose: Although it is well known that obesity increases the risk of atherosclerosis in carotid arteries, it is not clear whether this risk changes after obesity surgery. The aim of this study was to investigate whether weight reduction with a laparoscopic sleeve gastrectomy (LSG) has any effect on distensibility and elasticity which show subclinical atherosclerosis in the carotid arteries of obese individuals., Materials and Methods: This prospective study included 130 patients (body mass index (BMI) 48.21 ± 6.97 kg/m
2 ) who underwent LSG. The patients were followed up for 1 year. Comparisons were made of the distensibiliy and elasticity values calculated preoperatively and at 1, 3, 6, and 12 months, postoperatively., Results: There was a statistically significant increase in distensibility and elasticity values from baseline to 1, 3, 6, and 12 months postoperatively (p < 0.001 for both comparisons). The multiple linear regression analysis was used to find the variables affecting both distensibility and elasticity. According to the results, the presence of BMI decreases distensibility percentage change level by 0.38 units (β= - 0.38, 95% CI - 0.51;- 0.25, p < 0.001). The presence of fasting plasma glucose decreases elasticity percentage change level by 0.20 units. (β= - 0.20, 95% CI - 0.39; - 0.01, p = 0.037)., Conclusion: Carotid artery distensibility and elasticity values increase after LSG, and this change could be caused by the change in metabolic parameters and heart geometry. These results may indirectly suggest that subclinical atherosclerosis in carotid arteries has decreased after obesity surgery.- Published

- Abstract
Objective: Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases. The impact of AF on in-hospital outcomes in acute decompensated heart failure (ADHF) is controversial. The aim of this study is to determine the prevalence of AF among hospitalized patients with ADHF and describe the clinical characteristics and in-hospital outcomes of these patients with and without AF., Methods: We examined the multicenter, observational data from the real-life data of hospitalized patients with HF: Journey HF-TR study in Turkey that studied the clinical characteristics and in-hospital outcomes of hospitalized patients with ADHF between September 2015 and September 2016., Results: Of the 1,606 patients hospitalized with ADHF, 626 (39%) had a history of AF or developed new-onset AF during hospitalization. The patients with AF were older (71±12 vs. 65±13 years; p<0.001) and more likely to have a history of hypertension, valvular heart disease, and stroke. The AF patients were less likely to have coronary artery disease and diabetes. In-hospital adverse event rates and length of in-hospital stay were similar in ADHF patients, both with and without AF. In-hospital all-cause mortality rate was higher in patients with AF than in patients without AF, although the difference was not statistically significant (8.9% vs. 6.8%; p=0.121)., Conclusion: AF has been found in more than one-third of the patients hospitalized with ADHF, and it has varied clinical features and comorbidities. The presence of AF is not associated with increased adverse events or all-cause mortality during the hospitalization time.

- Abstract
Objective: Myocardial infarction is a leading cause of morbidity and mortality. Fibrinolytic administration is still a life-saving choice in ST-segment elevated myocardial infarction (STEMI), but the rate of successful reperfusion can be inconsistent. Failed reperfusion adds additional clinical risks to rescue percutaneous coronary intervention for STEMI patients. The interval between the peak of the T wave and the end of the T wave (Tpe) and the ratio of Tpe and a corrected measurement of the time from the start of the Q wave to the end of the T wave (Tpe/QTc ratio) are relatively new electrocardiogram (ECG) indices and have not yet been tested in STEMI patients treated with fibrinolytic agents., Methods: A total of 177 STEMI patients (mean age: 60.5±11.1 years; 138 men and 39 women) were enrolled in this retrospective study to evaluate ECG parameters. The Tpe interval and the Tpe/QTc ratio at baseline and at the 90th minute following the administration of fibrinolytic therapy were analyzed. The clinical and ECG findings of successful and failed reperfusion groups were compared., Results: Successful reperfusion was achieved in 119 patients (67.2%). The average Tpe interval on the admission ECG was shorter (91.7 vs. 100.9 milliseconds [ms]) (p<0.001) and shortened more in the successful reperfusion group (9.3 vs. 4.5 ms) (p<0.001). A cut-off value of 89.0 ms for the Tpe interval on the admission ECG was found to be related to reperfusion success with a sensitivity of 90.9%., Conclusion: The Tpe interval was a predictor for reperfusion success in STEMI patients treated with fibrinolytic agents.

- Abstract
Objective: There are various cardiovascular abnormalities in end-stage liver disease (ESLD). In these patients, left ventricular (LV) systolic function is normal at rest but deteriorates during stress. This deterioration may be due to subclinical myocardial dysfunction. This study evaluated global LV and right ventricular (RV) functions using 2-dimensional (2D) speckle tracking in patients with ESLD., Methods: Forty liver transplant candidates with ESLD and 26 healthy individuals were included in the study. All of the patients underwent conventional echocardiographic measurement. Longitudinal, circumferential, and radial strain measurements, as well as apical and parasternal short-axis image recordings were obtained. All 2D strain measurements were measured with offline analysis using velocity vector imaging (VVI) software., Results: In the apical 4- and 2-chamber measurements, the LV mean longitudinal strain was significantly lower in the patient group compared with that of the control group (-16.0±3.2% versus -17.6±2.2%, -16.7±3.3% versus -18.7 ±2.1 ± 2.1 %; p=0.002, respectively). The LV mean circumfe-rential strain did not differ between groups. The LV mean radial strain and RV longitudinal strain were significantly lower in the patient group (45.4±10.7 vs. 52.7±10.8%; p=0.01 and -19.2±3.5% versus -21.5±3.6%; p=0.03, respectively)., Conclusion: Subclinical impairment of global LV and RV systolic functions was determined in liver transplantation candidates using VVI. This deterioration was detected in longitudinal and radial deformation rather than circumferential deformation mechanics, which is consistent with early-stage LV myocardial dysfunction.

- Abstract
Background: Increased parathyroid hormone (PTH) level is associated with coronary artery disease, hypertension and left ventricular hypertrophy which are all predisposing factors for the ischemic cerebrovascular event (ICVE). Carotid intima-media thickness (CIMT) and aortic distensibility are the two early, subclinical predictors of atherosclerosis. The relation of PTH with CIMT and aortic distensibility in patients with ICVE has not been previously studied., Objective: Our aim was to study the relationship of PTH levels with aortic distensibility and CIMT in patients with ICVE., Methods: Sixty-four ICVE patients and 50 control group were enrolled in the study. PTH levels, aortic distensibility and CIMT were measured in all individuals., Results: PTH levels were significantly higher in ICVE patients than in the controls (60.1±21.6 vs. 52.3±6.2 pg/ml) (p=0. 008). PTH levels were found to be inversely correlated with aortic distensibility (r= -0. 420, p=0.001) and positively correlated with CIMT (r:0, 285, p=0,002)., Conclusion: The present study shows that PTH levels are increased in patients with acute ischemic cerebrovascular event compared to the control group. It also demonstrates that PTH levels are inversely related to aortic distensibility of ascending aorta and positively associated with CIMT., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Objective: Diffuse coronary artery disease (CAD) is a challenging issue in clinical cardiology practice. There are limited data about percutaneous revascularization in these patients., Methods: This study was an observational clinical evaluation. The records of patients with diffuse CAD revascularized with new-generation drug-eluting stents (DES) were researched retrospectively. Patients treated with multiple, overlapping new-generation DES (at least 60mm in length per vessel) were included. The incidence of major adverse cardiac events (MACE), defined as cardiac death, stent thrombosis, non-fatal myocardial infarction, and target lesion revascularization (TLR), at the end of the first year following the index procedure was recorded., Results: A total of 71 patients (with 75 coronary vessels) treated with new-generation DES for diffuse CAD were enrolled in the study. Zotarolimus-eluting stents were used in 48 vessels and biolimus A9-eluting stents were used in 27 vessels. The median total stent length per vessel was 75.0 mm (60.0-106.0) and the median number of stents implanted was 3 (2-4) for each vessel. The cumulative incidence of MACE at the end of the first year was 11.2% (8 patients). The presence of diabetes mellitus (DM) and ST-segment elevated myocardial infarction (STEMI) were defined as independent clinical risk factors related to MACE development., Conclusion: Coronary artery revascularization with new-generation drug-eluting stents can be a good choice in the treatment of selected patients with diffuse CAD. DM and STEMI were found to be related to poorer clinical outcomes with this treatment option in our study.

- Abstract
Objectives: The association between end-stage renal disease with atrial fibrillation and ventricular arrhythmias is well documented. The aim of this study was to investigate whether kidney transplant has any effect on P-wave dispersion, a predictor of atrial fibrillation and corrected QT interval dispersion, T-wave peak-end interval, and T-wave peak-end/corrected QT ratio, which are predictors of ventricular arrhythmias in patients with end-stage renal disease., Materials and Methods: In a retrospective study, 234 patients (125 kidney transplant and 109 healthy control patients) were examined. P-wave dispersion, corrected QT dispersion, T-wave peak-end interval, and T-wave peak-end/corrected QT ratio values before and 3, 6, and 12 months after transplant were calculated and compared in transplant recipients. Baseline values of the control group were compared with 12-month values of kidney transplant patients., Results: We observed a statistically significant decline in P-wave dispersion, corrected QT dispersion, T-wave peak-end interval, and T-wave peak-end/corrected QT ratio values among the pretransplant and 3-, 6-, and 12-month posttransplant measurements (P < .001 for all comparisons). However, the values of these measurements in the transplant group at 12 months were significantly higher than baseline values of the control group (P < .001 for all comparisons)., Conclusions: P-wave dispersion, corrected QT dispersion, T-wave peak-end interval, and T-wave peak-end/corrected QT ratio were shown to be attenuated after transplant, although they remained higher than baseline measurements in healthy individuals. These results indirectly offer that there may be a reduction in risk of atrial fibrillation and ventricular arrhythmias after transplant.

- Abstract
Background: The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented., Objective: The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals., Methods: In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined. The patients were followed 1 year. PWD and CQTD values before and 3rd, 6th, and 12th months after the surgery were calculated and compared., Results: There was a statistically significant decline in body mass index (BMI), PWD, and CQTD values among baseline, 3rd, 6th, and 12th months (p < 0.001 for all comparisons). Correlation analysis showed a statistically significant correlation between ΔPWD and ΔBMI (r = 0.719, p < 0.001), ΔPWD and Δleft ventricular end-diastolic diameter (LVEDD) (r = 0.291, p = 0.002), ΔPWD and Δleft atrial diameter (LAD) (r = 0.65, p < 0.001), ΔCQTD and ΔBMI (r = 0.266, p = 0.004), ΔCQTD and ΔLVEDD (r = 0.35, p < 0.001), ΔCQTD and ΔLAD (r = 0.289, p = 0.002). In multiple linear regression analysis, there was a statistically significant relationship between ΔPWD and ΔBMI (β = 0.713, p < 0.001), ΔPWD and ΔLVEDD (β = 0.174, p = 0.016), ΔPWD and ΔLAD (β = 0.619, p < 0.001), ΔCQTD and ΔBMI (β = 0.247, p = 0.011), ΔCQTD and ΔLVEDD (β = 0.304, p < 0.001), ΔCQTD and ΔLAD (β = 0.235, p = 0.009)., Conclusion: PWD and CQTD values of patients were shown to be attenuated after bariatric surgery. These results indirectly offer that there may be a reduction in risk of AF, ventricular arrhythmia, and sudden cardiac death after obesity surgery.

- Abstract
Objective: Since asthma and atherosclerosis may share similar pathophysiological mechanism, this study is planned to investigate whether epicardial fat thickness (EFT), carotid and femoral intima media thicknesses, which are markers of subclinical atherosclerosis, are increased in patients with asthma., Methods: The study was designed as a cross-sectional study. A total of 154 participants (83 patients with asthma and 71 healthy volunteers) were enrolled into the study. Epicardial fat, carotid, and femoral intima media thicknesses were measured and recorded in both groups. The statistical difference between the two groups was examined., Results: Both carotid and femoral intima media thicknesses were significantly higher in patients with asthma compared to control group (5.52 ± 0.4 mm vs. 5.36 ± 0.4 mm; p = 0.038 and 5.64 ± 0.4 mm vs. 5.46 ± 0.5 mm; p = 0.036, respectively). However, there was not a significant difference in EFT between the groups [5.9 mm (5.3-6.6; IQR = 1.3) vs. 5.6 mm (4.7-6.5; IQR = 1.8); p = 0.1]. On comparison of control group and asthma subgroups (mild, moderate, and severe), there was a statistically significant difference among these four groups in terms of carotid and femoral intima media thicknesses (p = 0.002 and p < 0.001, respectively). Subgroup analyses showed that this difference was mainly due to patients with severe asthma., Conclusions: Carotid and femoral intima media thicknesses in asthmatic patients were found to be increased compared to the normal population. As a result, the risk of subclinical atherosclerosis in asthmatic patients may be high.

- Abstract
Objective: The aim of this study was to investigate the relationship between oxidative/antioxidative stress markers and the diagnosis and complexity of coronary artery disease (CAD) in patients with stable CAD., Methods: A total of 145 patients were enrolled in the study. Based on coronary angiography results, the patients were categorized into 2 groups: those without CAD (Group 1) and those with CAD (Group 2). The patients in Group 2 were also categorized into low score and moderate/high score groups according to their SYNTAX score. The serum malondialdehyde (MDA) and total antioxidant capacity (TAOC) levels of Group 1 and Group 2 were compared. Finally, MDA and TAOC levels were compared between the moderate/high-risk and low-risk groups formed according to SYNTAX score., Results: There was a significant difference with respect to both serum TAOC and MDA levels between Group 1 and Group 2 (p=0.036 and p=0.029, respectively). The groups with a SYNTAX score 1-22 and with a SYNTAX score >22 were not significantly different with respect to serum TAOC or MDA level (p=0.582 and p=0.85, respectively)., Conclusion: The serum MDA level was significantly higher and the TAOC level was significantly lower in patients with stable CAD compared to those without; however, these molecule levels failed to predict disease complexity in patients with stable CAD.

- Abstract
Background: It is well-known that cardiovascular risk and all-cause mortality is increased in hemodialysis patients. Epicardial fat thickness (EFT), which reflects visceral adiposity, has been suggested as a new cardiometabolic risk factor. The purpose of this study was to investigate EFT in hemodialysis patients., Methods: A total of 144 consecutive patients (60 hemodialysis patients and 84 controls) were enrolled into the study, and patients with diabetes mellitus and cardiovascular diseases (CVD) were excluded. EFT was measured on the free wall of the right ventricle at end-diastole from the parasternal long-axis view by standard transthorasic 2D echocardiography., Results: The groups were similar in terms of sex distribution, age, blood pressure, heart rate and frequencies of CAD risk factors including smoking status, family history of CAD and hypertension. There were no significant differences between the hemodialysis patients and controls in 2D echocardiographic parameters, including ejection fraction and biochemical parameters except low-density lipoprotein, high-density lipoprotein and c- reactive protein. Despite having lower body mass index, EFT levels were significantly higher in hemodialysis patients compared to the controls (8.0 ± 2.2 mm vs. 5.8 ± 1.9 mm; p < 0.01). In multivariate linear regression analysis we determined that hemodialysis patient status was found to be an independent predictor for both EFT (β = 0. 700, p = 0.014) and carotid intima-media thickness (CIMT, β = 0. 614, p = 0.047)., Conclusions: Hemodialysis patients are independently associated with high EFT and CIMT.

- Abstract
Objective: The D-SPIRIT registry is designed to investigate the safety and efficacy of dabigatran etexilate in patients with nonvalvular atrial fibrillation (NVAF) and to collect data on outcomes in clinical practice., Methods: The D-SPIRIT is a national, prospective, observational, post-marketing registry involving patients with NVAF who have been taking dabigatran etexilate therapy for stroke prevention for a minimum of 6 months prior to enrollment. The registry will collect and analyze data from routine care, enrolling up to 600 patients in 9 centers. Patients will be followed up for 2 years to evaluate effectiveness and safety. A sample size of 600 subjects is proposed based on the following assumptions; Two-sided significance level of 0.05 (1-sided significance level of 0.025), ischemic stroke incidence rate of 0.768%-1.111%, hemorrhagic stroke incidence rate of 0.109%-0.130%, transient ischemic attack incidence rate of 0.722%-0.623%, therapy discontinuation incidence rate of 40% at day 730, and duration of enrollment period of 12 months with non-uniformed enrollment rate. Ethics approval was given by Dokuz Eylül University Ethics Committee of Clinical Research (2014/54) and approved by the Turkish Ministry of Health., Conclusion: Potential results of D-SPIRIT registry will add data from clinical practice to those from the RE-LY trial to expand knowledge of dabigatran etexilate treatment in patients with NVAF.

- Abstract
Coronary slow flow (CSF) may be a reflection of a systemic slow-flow phenomenon in the coronary arterial tree. In this study, the CSF group consisted of 24 men (77.4%) and 7 women (22.5%). An age- and gender-matched normal coronary artery (control) group was composed of 21 men (72.4%) and 8 women (27.5%). Retinal arteriovenous circulation time was measured using fundus fluorescein angiography as a part of the microcirculation and the circulation time between the antecubital vein and the retina as a part of the systemic circulation in patients with CSF and controls with normal coronary arteries. The mean arm-retina circulation time was 19.0 ± 5.7 seconds in the CSF group and 14.1 ± 3.1 seconds in the control group (p <0.001). The mean retinal arteriovenous passage time was 2.6 ± 0.9 seconds in the CSF group and 2.1 ± 0.7 seconds in the control group (p = 0.001). Strikingly, retinal findings of chronic central serous retinopathy were observed in 3 patients in the CSF group. In conclusion, CSF may indeed be a part of a systemic slow-flow phenomenon. The association of central serous retinopathy with this condition suggests that corticosteroids and the sympathetic system may play important roles in the pathogenesis of the disease by causing or contributing to increases in microvascular resistance and tonus., (Copyright © 2013 Elsevier Inc.
