Article Citation - WoS: 2Aging and cardiac implantable electronic device complications: is the procedure safe in older patients?(ELSEVIER, 2023) Günlü, Serhat; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground In this study, we investigated whether there is a higher incidence of cardiac implantable electronic devices (CIED) procedures related complications in older (≥75 years) than in younger (<75 years) patients. Methods This retrospective cohort study enrolled patients who had undergone CIED procedures (de novo implantation, system upgrade, generator substitution, pocket revision or lead replacement) at two heart centers in Turkey between January 2011 and May 2023. The primary composite endpoint included clinically signifcant hematoma (CSH), pericardial efusion or tamponade, pneumothorax, and infection related to the device system. Secondary outcomes included each component of the composite end point. Results The overall sample included 1923 patients (1419<75 years and 504 aged≥75 years). There was no diference between the groups in terms of cumulative events defned as primary outcome (3.5% vs. 4.4%, p=0.393). Infection related to device system was signifcantly higher in the≥75 age group (1.8% vs. 3.4%, p=0.034). There was no signifcant diference between the groups in terms of clinically signifcant hematoma and pneumothorax (0.7% vs. 0.4%, p=0.451, 1.4% vs. 1.0%, p=0.477, respectively). In multivariate model analysis, no association was found between age≥75 years and infection related to the device system. Conclusion Infection rates were relatively higher in the patient group aged≥75 years. This patient group should be evaluated more carefully in terms of infection development before and after the procedure.Article Citation - WoS: 2Citation - Scopus: 2Aging and cardiac implantable electronic device complications: is the procedure safe in older patients?(Springer, 2023) Günlü, Serhat; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiGIRIŞ Akut Kalp Yetmezliği (AKY) hastanın acil tıb- bi yardım alması için yeterince şiddetli bir kli- nik duruma, plansız bir hastaneye yatışa veya acil servis başvurusuna yol açan kalp yetmezliği semptomlarının ve/veya belirtilerinin hızlı veya aşamalı olarak başlamasını ifade eder (1). AKY’li hastalarının tedavilerinin planlanması için acil değerlendirilmesi gerekir. AKY, 65 yaş üstü kişi- lerde hastaneye yatışların önde gelen nedenidir (2). Yüksek mortalite ve tekrarlayan hastaneye yatış oranları mevcuttur. Hastane içi ölüm oranı %4 ila %10 arasında değişmektedir (3). Tabur- culuk sonrası 1 yıllık ölüm oranı %25-30, ölüm veya tekrar yatış oranları %45’ten fazladır (4). AKY, yeni başlayan KY’nin ilk belirtisi olabilir veya daha sıklıkla kronik KY’nin akut dekom- pansasyonuna bağlı ortaya çıkabilir (5). Akut de- kompanse kronik KY’si olan hastalarla akut pul- moner ödemli hastalar karşılaştırıldığında, akut pulmoner ödemi olanlar daha yüksek hastane içi mortaliteye sahiptirler ancak taburculuk sonra- sı mortalite ve yeniden hastaneye yatış oranları daha düşüktür (6). AKY’nin en sık tetikleyici fak- törleri atriyal fibrilasyon, akut MI veya iskemi, ilaç alımının (diüretik) kesilmesi, artmış sodyum yükü,miyokard fonksiyon bozukluklarına sebep olan ilaçlar ve aşırı fiziki efordur (7). Önceden var olan kardiyak disfonksiyonu olan hastalarda spesifik dış faktörler (anemi, GİS kanama, enfeksiyon vb.) AKY’yi hızlandırabilir (8).Book Part Atriyal Fibrilasyonda Kanama Riski Belirleme(2023) Kayan, Fethullah; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiGİRİŞ risk faktörlerinin modifikasyonu ile AF’nin ve kullanılan ilaçlarının(özellikle de antikoagülan- ların) komplikasyonlarının azaltılması önem arz etmektedir. Persistan ve Permanent AF’li olgularda eş- lik eden komorbiditelerin daha fazla olması ve yaşın daha ileri olması gibi nedenlerle, Parok- sismal AF’li olgulara göre, AF nin komplikas- yonları ve özellikle de antikoaülasyon tedavinse bağlı kanama riski daha yüksektir. AF tedavisinde, tromboembolik olayların önlenmesi için kullanılan Vitamin K Antago- nisti (VKA) ve Yeni Nesil Oral Antikoagülan- ların (YOAK) faydası; iskemik inme riskinde azalma ile major kanama olaylarındaki artma arasındaki dengeye bağlıdır. AF’nin tromboembolik riskinin önlenmesi için kullanılan oral antikoagülan tedavilere bağ- lı meydana gelebilecek kanamalar için gelişti- rilmiş olan Kanama Risk Skorlamaları; ORBİT, ATRİA, HAS-BLED, HEMORR2HAGES, ABC Skorlamalarıdır. Kullanılan bu skorlamalar ve risk grupları tablolar halinde gösterilmiştir. HAS-BLED Skoru: 0-2 puan alanlar düşük kanama risk grubunda bulunurken, HAS-BLED Atriyal Fibrilasyon (AF), dünya çapında erişkin- lerde en sık görülen aritmidir. AF, populasyon- da morbidite ve mortalitenin önemli bir nedeni olduğundan dolayı, hastalara, toplum sağlığına ve sağlık ekonomisine önemli bir yüktür. AF’ nin prevalansı, erişkinlerde yaklaşık ola- rak %2 ile %4 arasındadır. Yapılan çalışmalarda daha uzun yaşam süresi ile genel populasyonda tanı konmamış AF oranının 2,3 kat daha yüksek olduğu tahmin edilmektedir. İlerleyen yaş, AF nin önemli bir risk faktörü olmakla birlikte, Diyabetüs Mellitüs (DM), Hi- pertansiyon (HT), Kronik Böbrek Hastalığı(K- BH), Kalp Yetmezliği(KY), Koroner Arter Has- talığı (KAH), Obezite, Obstrüktif Sleep Apne Sendromu (OSAS) gibi bazı risk faktörleri de AF gelişiminde önemli rol oynar. Avrupa kökenli index yaşı 55 olanlarda, ya- şam boyu AF risk tahmini 4 kişiden 1 kişiyken, son yapılan revizyon ile 3 kişiden 1 kişi olmuş- tur. AF’ nin artan bu sayısı ile AF’ nin kendisi- ne ve kullanılan ilaçlara bağlı komplikasyonları da artmıştır. Değiştirilebilir ve kontrol edilebilirArticle The Diagnostic Role Of End-Tidal CO2 To Distinguish Unstable Angina Pectoris In Patients With Chest Pain(2023) Günlü, Serhat; Yeşil, Ahmet; Kayan, Fethullah; Karahan, Mehmet Zülkif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: Unstable angina pectoris (UAP), one of the acute coronary syndrome (ACS) types, is difficult to identify from non-cardiac chest pain (non-CCP), hence various strategies are applied for accurate diagnosis. This study aims to examine whether non-invasively measured end-tidal CO2 (ETCO2) can detect UAP in patients admitted to the emergency department (ED) with chest pain in the lack of a cardiovascular history. Methods: This research was conducted as a prospective observational study. The individuals were separated into two groups based on the inclusion and exclusion criteria: 75 patients with non-CCP and 75 UAP. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value cutoff. Using univariate regression analysis, the odds ratio of ETCO2 (with 95%CI) was computed for UAP prediction. Results: ETCO2 levels were substantially lower in the UAP group compared to the non-CCP group (p<0.001). Analysis of the ROC curve revealed that a decreased ETCO2 <35 predicted UAP with 78% sensitivity and 89% specificity (AUC:0.81, p <0.001). In addition, the negative predictive value was 71.6%, and the positive predictive value was 79.4%. Patients with UAP were 8.84 times more likely to have ETCO2 <35 than patients with non-CCP. Conclusion: UAP may be differentiated from non-CCP by ETCO2 measured as a non-invasive parameter in patients with chest pain.Presentation Diyastolik Disfonksiyon Tanısında Elektrokardiyografik Diyastolik Endeksinin Prognostik Rolü(2023) Günlü, Serhat; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAmaç: Sol ventrikülün diyastolik disfonksiyonu (LVDD), korunmuş ejeksiyon kalp yetmezliği olan bireylerde baskın etiyolojidir. Yüksek tansiyon miyokardda yapısal anormalliklere neden olur ve LVDD'nin seyrini hızlandırır. EKG özelliklerinden belirlenen elektrokardiyografik diyastolik indeks (EDI), sol ventrikül hipertrofisi ile LVDD'nin varlığı arasındaki bağlantı hakkında bilgi verebilir. Bu çalışmanın amacı, hipertansif bireylerde LVDD'yi tanımlamak için EDI göstergesini belirlemekti. Metod: Bu araştırmaya 2022 yılının Ocak ve Aralık ayları arasında sırayla 162 hipertansif hasta dahil edildi. Hastalar, LVDD'si olan ve olmayanlar olarak ayrıldı. [aVL R genliği (V1S genliği + V5R genliği)/PWLI genliği], EDI için formüllerdir. ROC eğrisi analizi kullanılarak, EDI'nin LVDD için öngörü değeri değerlendirildi. Tek değişkenli ve çok değişkenli lojistik regresyon analizi kullanılarak, LVDD'nin bağımsız faktörleri değerlendirildi. İki çok değişkenli model kullanıldı (model I: sürekli değişken olarak EDI ve kategorik değişken olarak model II). Sonuç: Hastalar LVDD olup olmamasına göre iki gruba ayrıldı (LVDD'si olmayan 85 hasta, grup 1; LVDD'si olan 77 hasta, grup 2). Araştırma örnekleminin ortalama yaşı 49±14 idi ve hastaların %42,6'sı erkekti. Çalışmaya katılanların EDI düzeyi 8,50±7,30 idi (Tablo 1). Tablo 1.

Grup 2'nin EDI puanı, grup 1'inkinden önemli ölçüde daha yüksekti (p <0.001). LVDD'yi tahmin etmek için EDI eğrisi altında kalan alan %0,752 olarak hesaplandı (%95 güven aralığı = 0,651-0,853; p<0,001) (Şekil 1). Şekil 1. ROC analysis of the EDI toestimatediastolicdysfunction EDI eşik değeri 7,4 mV'den büyük olduğunda, LVDD'yi %70'lik bir duyarlılık ve %69'luk bir özgüllükle tahmin eder. Tek değişkenli lojistik regresyon kullanılarak LVDD, EDI ile ilişkilendirildi [OR=1,248, %95 güven aralığı (CI)=1,159 - 1,345, p <0,001]. EDI'yi hem sürekli değişken hem de kategorik değişken olarak incelemek için iki farklı çok değişkenli regresyon modeli oluşturuldu. Her iki modelde de EDI'nin LVDD'nin erken bir göstergesi olduğu ortaya çıktı. Tartışma: Sol atriyal boyutlardaki değişikliklere tipik olarak septal veya arka sol ventrikül duvar kalınlığında bir artış eşlik eder ve bu da sonunda sol ventrikülün hipertrofisi veya yeniden şekillenmesi olarak kendini gösterir. Bu sonuçlar oldukça yaygın olduğundan ve hipertansif kalp hastalığı olan bireylerde artış gösterdiğinden, DD'li hastalarda görülen en yaygın anormalliklerden biridir. Birden fazla grup, DD'de sol ventrikül hipertrofisini ve anlamlı kardiyomiyosit hipertrofisinin histolojik kanıtları ve normalden daha büyük bir sol ventrikül kas kütlesi ile sistolik fonksiyonun korunduğu kalp yetmezliğini belgelemiştir. Arteriyel hipertansiyonu olan bireylerde, uzamış QRS ve QT/QTc aralığı gibi elektrokardiyografik karakteristiklerin genişlemiş bir sol ventrikül kas kütlesini düşündürdüğü bilinmektedir. Bu, DD ve QTc süresinin Doppler'den türetilen parametreleri arasında bir korelasyon olduğunu gösteren önceki çalışmalarla uyumludur. İkincisi ayrıca, uzun QT aralığı ile anormal mekanik fonksiyon arasındaki ilişkinin gözlemlendiği ve hayvan ve hücresel deneylerle desteklendiği kalıtsal uzun QT Sendromları kapsamındaki hastalar için literatürde kapsamlı bir şekilde tartışılmıştır. Patofizyolojik olarak, aksiyon potansiyeli süresinin uzaması, hücre içi kalsiyum birikimi yoluyla belirgin mekanik işlev bozukluğuna neden olabilir. Bununla birlikte, yukarıda belirtilen analizlerin tanısal performansının yanı sıra korelasyonu da, muhtemelen yalnızca bir elektrokardiyografik parametre kullanılarak belirli bir derecede basitleştirme nedeniyle oldukça mütevazıydı. Aslında, aynı grup tarafından daha yeni bir analizde önerildiği gibi, QTc uzamasına Ttepe – Eğilim aralığının uzaması neden olabilir. Önceki çalışmalardan farklılık büyük olasılıkla, ilkinde psödonormal ve/veya kısıtlayıcı dolum paterni olan hastaların daha büyük yüzdesi ile açıklanabilir, bu da daha ileri bir kardiyak hastalık aşamasını ve dolayısıyla daha belirgin repolarizasyon değişikliklerini düşündürür. Tedavi: EDI, ucuz olması, kolayca bulunabilmesi ve uygulanmasının basit olması nedeniyle hipertansiyon nedeniyle takip edilen bireylerde DD'yi tahmin etmek için önemli bir tarama modelidir.Article Citation - WoS: 1Citation - Scopus: 1The effect of body mass index on complications in cardiac implantable electronic device surgery(WILEY, 2023) Günlü, Serhat; Aktan, Adem; Kılıç, Raif; Kılıç, Raif; Arslan, Bayram; Günlü, Serhat; Altıntaş, Bernas; Karahan, Mehmet Zülkif; Özbek, Mehmet; Aslan, Burhan; Arpa, Abdulkadir; Coşkun, Mehmet Sait; Altunbaş, Mahsum; Tüzün, Rohat; Akgümüş, Alkame; Karadeniz, Muhammed; Aydın, Saadet; Güzel, Hamdullah; Aslan, Selen Filiz; Söner, Serdar; Taş, Ahmet; Ertaş, Faruk; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground: Cardiac implantable electronic device (CIED) procedures are prone to complications. In our study, we investigated the effect of body mass index (BMI) on CIED-related complications. Methods: 1676 patients who had undergone CIED surgery (de novo implantation, system upgrade, generator change, pocket revision or lead replacement) at two heart centers in Turkey and met the study criteria were included in our study. For analysis of primary and secondary endpoints, patients were classified as non-obese (BMI < 25 kg/m2), overweight (25 ≤ BMI < 30 kg/m2), and obese (BMI ≥ 30 kg/m2). The primary endpoint was accepted as cumulative events, including the composite ofclinically significant hematoma (CSH), pericardial effusion or tamponade, pneumoth- orax, and infection related to the device system. Secondary outcomes included each component of cumulative events. Results: The rate of cumulative events, defined as primary outcome, was higher in the obese patient group, and we found a significant difference between the groups (3.0%, 4.3%, 8.9%, p = .001). CSH and pneumothorax rates were significantly higher in the obese patient group (0.3%, 0.9%, 1.9%, p = .04; 1.0%, 1.4%, 3.3%, p = .04, respectively). According to our multivariate model analysis; gender (OR:1.882, 95%CI:1.156–3.064, p = .01), hypertension (OR:4.768, 95%CI:2.470–9.204, p < .001), BMI (OR:1.069, 95%CI:1.012–1.129, p = .01) were independent predictors of cumulative events rates. Conclusions: Periprocedural complications associated with CIED (especially hematoma and pneumothorax) are more common in the group with high BMI.Article Effect of cardio-gastric interaction on atrial fibrillation in GERD patients(2023) Günlü, Serhat; Aktan, Adem; Kayan, Fethullah; Karahan, Mehmet Zülkif; Bernas, Altıntaş; Karahan, Mehmet Zülkif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: Atrial fibrillation (AF) and gastroesophageal reflux disease (GERD) are very common in daily clinical practice. Post-prandial AF episodes have been reported in GERD patients. Although it was reported in previous studies that it was caused by sympathovagal imbalance, there are no studies on cardiac conduction system involvement. In this study, we aimed to evaluate whether the risk of developing AF increases in untreated GERD patients with non-invasive electrophysiological tests. Methods: The research was prospectively performed. Endoscopy was performed on the individuals due to reflux complaints. ECG was recorded at 25mm/s and 10 mm/mV amplitude, and 24-hour Holter ECG (three-channel; V1, V2, and V5) was performed. ECG parameters were measured and Holter ECG results were analyzed. Results: A total of 120 individuals, 60 patients and 60 controls, were included. No significant statistically differences existed between groups for hypertension, diabetes, smoking, or dyslipidemia (p>0.05). In terms of heart rate, Pmax, Pmin, QTd, and QTcd, there were no significant differences across the two groups (p>0.05). P-wave dispersion (Pd) was substantially higher in the study group (p=0.014). Comparing the heart rate variabilities of 24-hour Holter ECG recordings across the groups, the standard deviation of R-R intervals (SDNN) was substantially higher in the study group (p<0.001). Low Frequency (LF) and LF/HF were significantly higher in the control group (p<0.001 and p=0.003, respectively). AF was detected in nine individuals on Holter ECG. Conclusion: Pd duration and risk of developing AF were higher in GERD patients.Article Citation - Scopus: 6The effect of coronary slow flow on ventricular repolarization parameters(ScienceDirect, 2023) Karahan, Mehmet Zülkif; Aktan, Adem; Günlü, Serhat; Kılıç, Raif; Kılıç, Raif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiIntroduction: Ischemia due to microvascular dysfunction may be responsible for the heterogeneity of ventricular repolarization in coronary slow flow. To our knowledge, there is no study in which QT interval, Tp-Te interval, index of cardiac-electrophysiological balance (iCEB), and frontal QRS-T angle were evaluated together in patients with CSF. In this study, we examined for the first time the relationship between all these myocardial repolarization parameters and CSF. Materials and methods: The study group included 178 patients (99 female, mean age: 50.6 ± 8.6 years) with isolated CSF without stenotic lesions and with angiographically proven normal coronary arteries. The control group included 120 patients (71 female, mean age: 49.3 ± 9.4 years) with normal coronary angiography. QRS duration, QT interval, QTc interval, Tp-Te interval, Tp-Te/QT, Tp- Te/QTc, iCEB score, and frontal QRS-T angle were calculated from 12‑lead ECGs. Results: There was no significant difference in demographic parameters between the two groups. Compared with the control group, patients with CSF had significantly longer QTmax duration, QT dispersion, Tp-Te interval, and higher iCEB score, wider frontal QRS-T angle. Conclusion: In our study, we found that many of the ventricular repolarization parameters were adversely affected in patients with CSF. Impaired parameters may be associated with the risk of malignant ventricular arrhythmias.Article The effect of coronary slow flow on ventricular repolarization parameters(ELSEVIER, 2023) Günlü, Serhat; Karahan, Mehmet Zülkif; Aktan, Adem; Kılıç, Raif; Kılıç, Raif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground: Cardiovascular (CV) risk factors are associated with high morbidity and mortality rates; however, prevalence data for Turkish military members are unknown. Aim: This study determines how common cardiovascular risk factors are among military members in the Corps Command Military Unit and how they relate to socio-demographic parameters. Materials and Methods: A cross-sectional research was conducted with 25222 active-duty individuals. A questionnaire was used to assess cardiovascular risk factors. This study included patients with more than two risk factors or current cardiac complaints. ECGs, echocardiograms, and biochemical testing were performed. Results: The study employed 835 individuals with an average age of 19.43±2.12 years. 19.6% of them had hypertension, 5.6% had dyslipidemia, 39.6% were smokers, 2.4% had diabetes mellitus, and 9.8% had a positive family history. Physical activity frequency was not observed in 54% of the patients before enlisting in the military. There was a significant positive correlation between smoking and mental stress (r=1.07, p<0.001). Conclusion: In terms of cardiovascular risk, hypertension and smoking were found to be the most prevalent among the Corps command staff. Therefore, this study provides compelling evidence that military healthcare providers should conduct annual periodic checks on those at risk for cardiovascular diseases.Article Evaluation of Frontal QRS-T Angle in Patients with Coronary Artery Ectasia(Sociedade Brasileira de Cardiologia – SBC, 2023) Günlü, Serhat; Karahan, Mehmet Zülkif; Aktan, Adem; Kayan, Fethullah; Günlü, Serhat; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground: Coronary artery ectasia (CAE) is defined by focal enlargement of the coronary artery exceeding 1.5 times the adjacent normal segment. CAE can often cause arrhythmias, heart failure, sudden death, and myocardial ischemia. Ischemia due to microvascular dysfunction may be responsible for the ventricular heterogeneity in CAE. Objectives: The aim of our study was to evaluate the frontal QRS-T angle in patients with CAE. Methods: Our study included 55 patients with CAE and 50 individuals in the control group. Demographic characteristics and electrocardiographic parameters were compared between the two groups. Categorical variables were compared using the chi-square test. Continuous variables were compared using unpaired Student’s t-test. P values < 0.05 were considered statistically significant. The frontal QRS-T angle was calculated from 12-lead electrocardiograms (ECGs) using the automatic report from the electrocardiography machine. Results: The average age of patients with CAE was 63.2 ± 3.4 years, with 18 women among them. The control group had an average age of 61.1 ± 3.2 years, with 28 women included. There was no significant difference in demographic parameters between the two groups. Compared to the control group, patients with CAE had significantly wider frontal QRS-T angle (p < 0.001), as well as longer QTmax duration, p = 0.002; Tp-Te interval, p = 0.02; and QT dispersion (QTd), p = 0.04. Conclusion: The frontal QRS-T angle can be calculated easily and time-efficiently using surface electrocardiography. In this study, we showed for the first time that the frontal QRS-T angle was significantly increased in patients with CAE.Article Citation - Scopus: 2Evaluation of Frontal QRS-T Angle in Patients with Coronary Artery Ectasia(Sociedade Brasileira de Cardiologia, 2023) Karahan, Mehmet Zülkif; Aktan, Adem; Kayan, Fethullah; Günlü, Serhat; Günlü, Serhat; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

Results: The average age of patients with CAE was 63.2 ± 3.4 years, with 18 women among them. The control group had an average age of 61.1 ± 3.2 years, with 28 women included. There was no significant difference in demographic parameters between the two groups. Compared to the control group, patients with CAE had significantly wider frontal QRS-T angle (p < 0.001), as well as longer QTmax duration, p = 0.002; Tp-Te interval, p = 0.02; and QT dispersion (QTd), p = 0.04. Conclusion: The frontal QRS-T angle can be calculated easily and time-efficiently using surface electrocardiography. In this study, we showed for the first time that the frontal QRS-T angle was significantly increased in patients with CAEArticle Citation - WoS: 2Evaluation of Hematological Parameters After Transcatheter Aortic Valve Replacement(SAGE, 2023) Günlü, Serhat; Karahan, Mehmet Zülkif; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Demir, Muhammed; Ertaş, Faruk; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

The present study investigated the changes in hematologic parameters to evaluate whether they predict mortality or major bleeding. We enrolled 248 consecutive patients (44.8% male; mean age 79.0 ± 6.4 years) undergoing TAVR. In addition to demographic and clinical examination, blood parameters were recorded before TAVR, at discharge, 1 month and 1 year. Hemoglobin levels before TAVR 12.1 ± 1.8 g/dL, 10.8 ± 1.7 g/dL at discharge, 11.7 ± 1.7 g/dL at first month, 11.8 ± 1.4 g/dL at first year (Hemoglobin values compared with pre-TAVR, P < .001, P = .019, P = .047, respectively). Mean platelet volume (MPV) before TAVR 8.72 ± 1.71 fL, 8.16 ± 1.46 fL at discharge, 8.09 ± 1.44 fL at first month, 7.94 ± 1.18 fL at first year (MPV values compared with pre-TAVR, P < .001, P < .001, P < .001, respectively). Other hematologic parameters were also evaluated. Hemoglobin, platelet count, MPV, and red cell distribution width before the procedure, at discharge, and at the first year did not predict mortality and major bleeding in receiver operating characteristic analysis. After multivariate Cox regression analysis, hematologic parameters were not independent predictors of in-hospital mortality, major bleeding, and death at 1 year after TAVR.Article Citation - WoS: 2Citation - Scopus: 2Evaluation of Hematological Parameters After Transcatheter Aortic Valve Replacement(Sage Journals, 2023) Karahan, Mehmet Zülkif; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Günlü, Serhat; Demir, Muhammed; Ertaş, Faruk; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: The frontal QRS-T angle (fQRS-T) is associated with myocardial ischemia and ventricular arrhythmias. On the other hand, acute pulmonary embolism (APE) is a major risk factor for cardiac adverse events. This research aimed to determine whether the fQRS-T, a marker of ventricular heterogeneity, can be used to predict successful thrombolytic therapy in patients with APE. Methods: This was a retrospective observational study. Patients diagnosed with APE and hospitalized in the intensive care unit between 2020 and 2022 were included in the research. A total of 136 individuals with APEs were enrolled in this research. The patients were divided into two groups: thrombolytic-treated (n=64) and non-treated (moderate to severe risk, n=72). An ECG was conducted for each patient, and echocardiography was performed. Results: The mean age of the thrombolytic group was 58.2±17.6 years, with 35 females (55.1% of the group) and 29 males (44.9%). The non-thrombolytic group had a mean age of 63.1±16.2, with 41 females (56.5%) and 31 males (43.5%). Respiratory rate, heart rate, and fQRS-T were higher in the thrombolytic group, and oxygen saturation ratio and systolic and diastolic blood pressure were higher in the non-thrombolytic group (p=0.006, p<0.001, p=0.021; p<0.001, p=0.015, p<0.001, respectively). In the thrombolytic therapy group, comparing pre- and post-treatment ECG data revealed a statistically significant change in the fQRS-T value (p=0.019). Conclusion: The fQRS-T may provide important clues for the successful treatment of APEsBook Part Kardiyovasküler Hastalıklarda Beslenme(2023) Kayan, Fethullah; Karahan, Mehmet Zülkif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiKronik hastalık, uzun süreli tedavi gerektiren ve hayatı boyunca sürebilecek bir sağlık durumunu ifade eder. Bunlar, diyabet, hipertansiyon, kalp hastalığı, kanser, multipl skleroz gibi bir dizi farklı hastalığı içerebilir. Kronik hastalık tanısı alan bireylerin ve ailelerin yaşamlarında büyük bir etkiye sahip olabilir ve duygusal, sosyal ve fiziksel zorluklara neden olabilir. Bu nedenle, kronik hastalık tanısı almış bireylerle ve aileleriyle iletişim kurarken dikkatli ve duyarlı olmak önemlidir (1). İletişim, bireylerin duygularını ifade etmelerine, endişelerini paylaşmalarına ve birbirleriyle destek sağlamalarına yardımcı olabilir. Kronik hastalıkla ilgili iletişim becerileri, bireylerin sağlıklı bir şekilde başa çıkmalarına ve daha iyi sonuçlar elde etmelerine yardımcı olabilir. Kronik hastalık tanısı almış bireyler ve aileleri arasındaki iletişim, aşağıdaki bazı temel prensiplere dikkat ederek etkili bir şekilde gerçekleştirilebilir: Açık iletişim kurma: Kronik hastalık tanısı almış bir bireyin ve ailesinin duygularını ve deneyimlerini anlamak için empati kurmak önemlidir. Açık iletişim, dürüst, saygılı ve etkili bir iletişim tarzını içerir. Kronik hastalık tanısı almış bir birey ve ailesiyle iletişim kurarken açık ve net olmak önemlidir. VII. Sonuç Kronik hastalık tanısı almış bireyler ve aileleriyle etkili iletişim kurmak önemlidir. Etkili iletişim, hastaların sağlık sonuçlarını, yaşam kalitesini ve memnuniyetini artırabilir. Ailelerin de katılımıyla birlikte, uygun tıbbi bakım sağlanabilir ve sağlıklı bir iyileşme süreci desteklenebilir. Bu nedenle, sağlık profesyonellerive diğer ilgili paydaşlar, hastalarla etkili iletişim kurma becerilerini geliştirmek için yönlendirilmelidir. Kronik hastalık yönetiminde etkili iletişim, hastaların ve ailelerinin gereksinimlerini anlamak ve onları desteklemek için vazgeçilmez bir araçtır.Article Local Against General Anesthesia For Transcatheter Aortic Valve Replacement(Bandırma Onyedi Eylül Üniversitesi Tıp Fakültesi, 2023) Günlü, Serhat; Kayan, Fethullah; Aktan, Adem; Karahan, Mehmet Zülkif; Tanırcan, Muhammed Raşid; Karahan, Mehmet Zülkif; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground/Aims: Transcatheter aortic valve replacement (TAVR) poses significant challenges concerning anesthesia management. There is no consensus on the type of safer anesthesia for TAVR procedures. We aimed to evaluate the effectiveness and safety of TAVR performed with trans-femoral approach under local anesthesia with sedation (LAS) against general anesthesia (GA). Methods: This observational and retrospective analysis included individuals who were admitted on a planned basis from 2016 to 2022 and underwent Transfemoral TAVR. Effectiveness and safety outcomes were evaluated at 30 days. İndividuals were separated into two groups: GA and LAS. Demographic characteristics and procedural data were recorded during hospitalization. Results: 115 patients were included, of whom 62 (53.9%) received LAS and 53 received GA (46.1%). 59 female (48.8%) patients with a mean age of 83.2±5.7 participated in the study. Successful TAVR procedure was performed in 100 (86.9%) of 115 patients with the transfemoral approach. The mean procedure time was 136.7±46.7 minutes, and the procedure time was shorter in patients who underwent LAS against GA (p=0.001). There were no differences among the groups including fluoroscopy time, contrast, and radiation dose (p>0.05). In 2 patients (3.2%), significant vascular complications necessitated immediate surgical intervention, necessitating a change in the anesthesia technique. Overall 30-day mortality was 5.2%, with no significant differences among the groups (GA 7.5% vs. LAS 3.2%, p =0.28). GA had substantially longer ICU and total hospitalization stays than LAS (p=0.009 and p =0.004, respectively). Conclusions: In our study, TAVR via the transfemoral route using LAS was an alternative for GA.Presentation METABOLİK SENDROM VE KARDİYO-ELEKTROFİZYOLOJİK DENGE(2023) Kayan, Fethullah; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAmaç: Kardiyovasküler morbidite ve ölüm, metabolik sendromun daha yüksek prevalansıyla ilişkilidir. Kardiyak elektrofizyolojik denge indeksi (iCE), QT aralığı/QRS süresi olarak tanımlanır ve yükselmiş Tp-e/QT oranı kötücül ventriküler aritmilere ilişkin öngörücüdür. Bu araştırmanın amacı, metabolik sendrom (MS) ile iCE ve Tp-e/QT oranı arasındaki ilişkiyi belirlemektir. Yöntem: Bu araştırma, 40 ila 70 yaş arasındaki 90 hastadan oluşmaktadır ve iki gruba ayrılmıştır: metabolik sendromlu 45 hasta (21 erkek, ortalama yaş 58.7±1.4 yıl) ve kontrol grubu (24 erkek, ortalama yaş 55.1±2.3 yıl). Tüm hastalara standart 12 derivasyonlu elektrokardiyogram kaydı yapıldı. Tp-e aralığı, QT aralığı, QRS süresi, Tp-e/QT oranı ve QT/QRS oranı belirlendi. Sonuçlar: İki grup arasında temel özellikler açısından istatistiksel olarak anlamlı bir farklılık bulunmadı (Tablo 1).
