    by Umut Kocabaş, Isil Ergin, Sadi Can Sönmez, Veysel Yavuz, Selda Murat, Ibrahim Halil Özdemir, Ömer Genç, Haşim Tüner, Bengisu Keskin Meriç, Onur Aslan, et al.

    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.


  • Assessment of transabdominal fat volumes as a predictor of prognosis in patients undergoing transcatheter aortic valve replacement

    by Ahmet Guler, Omer Genc, Abdullah Yildirim, Orsan Deniz Urgun, Aslan Erdogan, Okan Dilek, Omer Sen, Bozkurt Gulek, Ibrahim Halil Kurt

    Transcatheter aortic valve replacement (TAVR) has emerged as a well-established treatment option for eligible patients with severe aortic stenosis. This study aimed to investigate the correlation between abdominal fat tissue volumes, measured using computed tomography (CT), and all-cause mortality in patients undergoing TAVR. The study included 258 consecutive patients who underwent TAVR at a single center between September 2017 and November 2020. During the preoperative preparation, CT scans were used to perform a semi-quantitative measurement of abdominal fat components. Body mass index (BMI) for each participant was calculated. The relationship between fat parameters and overall survival was determined using multivariable Cox proportional hazards models. Participants had a mean age of 76.8 ± 7.8 years, of whom 32.9% were male. The median follow-up period was 12 months, during which 38 patients (14.7%) died. Both the survivor and non-survivor groups showed comparable risk factors. Regarding transabdominal fat volume parameters, deceased individuals exhibited significantly lower values. However, no significant differences were observed in BMI and transabdominal area measurements. Among transabdominal fat parameters, only subcutaneous fat volume [adjusted Hazard Ratio (aHR) = 0.83, p = 0.045] and total fat volume (TFV) [aHR = 0.82, p = 0.007] were identified as significant predictors of reduced all-cause mortality. Furthermore, TFV demonstrated the highest discriminative performance with a threshold of ≤ 9.1 L (AUC = 0.751, p < 0.001, sensitivity 71.1%, specificity 70.9%). Preoperative CT-based abdominal fat volume parameters, particularly TFV, can serve as potential predictors of survival in patients undergoing TAVR.

    Novel insights into myocardial injury, diastolic pathology, and in-hospital mortality: the impact of H2FPEF score in COVID-19 patients

    by Ömer Genç, Abdullah Yıldırım, Gökhan Alıcı, Tayfur Erdoğdu, Örsan Deniz Urgun, Aslan Erdoğan, Eyüp Özkan, Şerafettin Demır

    Aims: H2FPEF score is a reliable tool for diagnosing heart failure with preserved ejection fraction (HFpEF) linked to diastolic dysfunction. Our objective was to explore the correlation between H2FPEF score and in-hospital mortality, as well as parameters previously identified in association with COVID-19, among hospitalized COVID-19 patients. Methods: This prospective, single-center observational study included 205 consecutive COVID-19 hospitalized patients. Data regarding patients' clinical status, comorbidities, and drug therapy were extracted from medical histories and records. Afterward, we calculated H2FPEF score for each patient and subsequently grouped them based on the following score categories: low (0-1), medium (2-5), and high (6-9). Logistic regression and Kaplan-Meier survival curve analyses were conducted to assess in-hospital mortality and the presence of an intermediate-to-high H2FPEF score. Results: Death occurred in 46 (22.4%) patients. 79 participants (38.5%) fell into the low-risk category (0-1 points), 108 (52.7%) were classified as intermediate-risk (2-5 points), and the remaining 18 (8.8%) were in the high-risk category (6-9 points). Age, heart rate, body mass index, and co-morbidities exhibited a rising trend with increasing H2FPEF scores (p<0.05 for all). Moreover, an escalation in the H2FPEF category correlated with deteriorated echocardiographic parameters. Multivariable logistic regression analysis revealed that heart rate per minute (OR=1.048, p=0.022), H2FPEF score (OR=1.396, p=0.018), and current smoker (OR=4.569, p=0.050) were independent determinants of in-hospital mortality. ROC curve indicated that the H2FPEF score, with a threshold of ≥2, exhibited good discriminative capacity, demonstrating 80.4% sensitivity and 69.2% specificity (AUC=0.777, p<0.001). The pairwise comparison of ROC curves analysis demonstrated that troponin (AUC=0.819) exhibited better discriminative abilities than both D-dimer (AUC=0.737, p=0.029) and hemoglobin (AUC=0.691, p=0.007) in determining an intermediate-to-high H2FPEF score. Conclusion: COVID-19, recognized for its association with myocardial damage, could emerge as a significant risk factor for the onset of HFpEF. H2FPEF score presents as a straightforward tool for rapid risk assessment upon hospitalization, potentially aiding in the evaluation of the risk for HFpEF development. Its utilization may facilitate early intervention, thereby contributing to a reduction in poor outcomes.

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

    by Umut Kocabaş, Isil Ergin, Veysel Yavuz, Selda Murat, Ibrahim Özdemir, Ömer Genç, Cihan Altın, Haşim Tüner, Bengisu Keskin Meriç, Ali Çoner, et al.

    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.

    Mortality Outcomes of Single-staged versus Multi-staged Complete Coronary Revascularization in Multivessel Non-ST Elevation Myocardial Infarction Patients

    by Gökhan Alici, Alaa Qui̇sİ, Omer Genc, Hazar Harbalioğlu, Samir Allahverdi̇yEv, Abdullah Yildirim, Örsan Deniz Urgun, Mustafa Gür

    Aim: The aim of this study was to compare the short-term and long-term mortality results of single-stage percutaneous coronary intervention (SS-PCI) and multi-stage percutaneous coronary intervention (MS-PCI) strategies in patients diagnosed with non-ST segment elevation myocardial infarction (NSTEMI) with multivessel disease. Material and Methods: A total of 298 consecutive patients diagnosed with multivessel NSTEMI (71 (23.8%) patients in the SS-PCI group and 227 (76.2%) patients in the MS-PCI group) were included in this study. Data regarding mortality were obtained from the health information system of our institute and national health registry. Results: Although in-hospital mortality rates were found to be significantly higher in univariate analysis in the SS-PCI group compared to the MS-PCI group (14.1% (n=10) vs 4.0% (n=9); p=0.005), it was not independently associated with total mortality in multiple model. Among the parameters predicted mortality determinants, low hemoglobin (odds ratio (OR)=0.485, 95% confidence interval (CI)=0.332-0.708; p=0.002), No-reflow occurrence (OR=6.194, 95% CI=1.310-29.300, p=0.021), not using post dilatation (OR=0.287, 95% CI=0.085-0.970, p=0.045) were independently associated with total mortality. Conclusion: There was no statistical difference in overall mortality between the two study groups in multivessel NSTEMI patients who underwent complete coronary revascularization with the SS-PCI and MS-PCI strategy, while low hemoglobin, No-reflow phenomenon, and not using post-dilatation were found as independent predictors of mortality.

  • Impact of objective nutritional indexes on 1-year mortality after transcatheter aortic valve implantation: a prospective observational cohort study

    by Mehmet Kucukosmanoglu, Salih Kilic, Orsan Deniz Urgun, Seyda Sahin, Arafat Yildirim, Omer Sen, İbRahim Halil Kurt

    Introduction: The prognostic value of objective nutritional indexes has been demonstrated in many diseases. This study evaluated the prognostic value of these indexes in patients who underwent transcatheter aortic valve replacement (TAVI). Material and methods: Totally, 119 consecutive patients who underwent TAVI between January 2016 and December 2018 were evaluated. All patients were followed-up for one year. Objective nutritional index (geriatric nutritional risk index [GNRI], prognostic nutritional index [PNI]) and controlling nutritional status [CONUT]) scores were calculated before TAVI. Results: Mean age of the study population was 77.1 ± 7.8 years (59.7% female). During one-year follow-up, 31 (26.1%) deaths were observed. In a Kaplan–Meier analysis, mortality rates were significantly increased in patients with lower GNRI and PNI and higher CONUT scores (50.01% vs. 4.4%; p < .001, 48.1% vs. 15.2%; p < .001, 57.5% vs. 12.8%; p < .001, respectively). Pairwise comparisons of the ROC curves demonstrated that the GNRI score was a significantly better predictor of mortality than the PNI and CONUT scores (area under curve; 0.898, 0.664, and 0.722, respectively, for both; p < .001). According to Cox proportional hazard analyses, the GNRI (hazard ratio [HR]: 0.898) and STS (HR: 1.359) score were independently associated with increased 1-year mortality (for all p < .05). Conclusion: The GNRI, PNI and CONUT scores were associated with 1-year all-cause mortality in patients who underwent TAVI. The predictive value of the GNRI score was significantly better than the PNI or CONUT scores. Assessment of the GNRI should be considered before TAVI.


  • Morning blood pressure surge increases in patients with hypertensive primary hyperparathyroidism and is independently associated with serum calcium level

    by Derya Demirtas, Hilmi Erdem Sumbul, Abdullah Orhan Demirtas, Yahya Kemal Icen, Erdinc Gulumsek, Hasan Koca, Örsan Deniz Urgun, Mevlut Koc

    Introduction: There is not enough data on the effects of primary hyperparathyroidism (pHPT) on morning blood pressure surge (MBPS) in the literature. We aimed to determine whether there was any change in MBPS value in patients with hypertensive pHPT and to determine the parameters related to MBPS. Method: 80 patients with newly diagnosed pHPT with hypertension (HT) and 80 controls with newly diagnosed hypertension were included. Routine laboratory examinations and ambulatory blood pressure monitoring (ABPM) were performed in all patients. Results: In patients with pHPT, blood urea nitrogen (BUN), triglyceride, hs-CRP, uric acid, serum calcium (Ca), parathormone (PTH), daytime SBP and MBPS levels are higher than others (p < 0.05). Body mass index (BMI) and Ca level were independently associated with MBPS. In patients with MBPS ≥ 25 mmHg, BMI, BUN, creatinine, uric acid, Ca and PTH levels were found to be higher than others. BMI values and Ca levels determine the patients with MBPS ≥ 25 mmHg (p < 0.05) independently. According to this analysis, increase in BMI (for each 1 unit) and Ca level (for each 0.1 mg/dL) was found to increase the probability of MBPS ≥ 25 mmHg by 17.8% and 7.7%, respectively. When the cut-off value for Ca was taken as 10 mg/dL, the patients with MBPS ≥ 25 mmHg were determined with 73.5% sensitivity and 73.1% specificity. Conclusion: MBPS significantly increases in patients with newly diagnosed hypertensive pHPT. This increase in MBPS is closely associated with increased Ca levels. In patients with pHPT, lowering the Ca level below 10 mg/dL may have clinical implications.
