Vatanından Uzakta Ölmek” Palyatif Bakım Kliniğinde Ölen 7 Suriye Uyruklu Hasta ve Ülkemizin Sığınmacıların Sağlık İhtiyaçlarını Karşılamadaki Rolü
(2022) Akelma, Hakan; Karahan, Mehmet Zülkif
Savaşlar, iç çatışmalar telafisi mümkün olmayan yıkımlara neden olup, en çok da sivilleri etkilemektedir. Yıkımın etkisi başta ikincil şahıslara ihtiyaç duyan çocuk, yaşlı ve kadınlar için daha belirgindir. Şu anda dünyadaki sığınmacıların yarısından fazlası Suriye’de hayatlarını kurtarmak için ülkelerinden ayrılmak zorunda kalan sığınmacılardan oluşmaktadır. Siyasal, sosyal, kültürel ve ekonomik açıdan toplumu ve bireyleri etkileyen yurdundan edilme durumu sağlık sorunlarını da beraberinde getirmektedir. Sığınmacılar zor yaşam koşulları, barınma, beslenme, şiddet ve psikolojik travmalar gibi birçok neden ile sağlık bakım sisteminde en kırılgan ve savunmasız gruplardandır. Kendi yaşam alanlarından zorunlu olarak ayrılan bireylerin yaşam konforlarının azalması ve yaşadıkları psikolojik yıkım, beraberinde bulaşıcı hastalıklar, kardiyovasküler hastalıklar, diyabet, kanser ve akciğer hastalıkları gibi kronik hastalıkların riskini artırmaktadır. Bu hastalıklara bağlı palyatif bakım ünitelerine yatışlar artmakta ve bu kliniklerde yaşam koşullarından daha iyi şartlarda sağlık hizmeti almakta ancak hastalıklarının şiddetine göre ölümler gerçekleşmektedir. Türkiye, sığınmacılara mümkün olan en iyi yaşam koşullarını ve kapsamlı insani yardımı sağlamaktadır. Sığınmacılar hem kamplarda hem de barındıkları iskânlarda tüm sağlık hizmetlerini sürdürmektedir. Bu sığınmacılar aynı şekilde gerekli durumlarda palyatif bakım hizmetlerinden faydalanmaktadır. Bu çalışmanın amacı palyatif bakım kliniklerde özellikle kanser, diyabet ve diğer kronik hastalıklar sonucu hayatını kaybeden sığınmacı hastaların değerlendirilmesi ve bunun yanında ülkemiz sağlık bakımındaki desteğini vurgulamaktır.
An Evaluation of Cardiovascular Risk Factors Among Military Personnel: A Study Conducted in Turkey
(2022) Günlü, Serhat; Karahan, Mehmet Zülkif
Background: 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.

The Significance of Frontal Plane QRS-T Angle for Estimating Non-Dipper Hypertension
(Cureus, 2022) Karahan, Mehmet Zülkif; Karahan, Mehmet Zülkif
Objective: The frontal QRS-T angle (fQRS-T) is linked to myocardial ischemia and ventricular arrhythmias. On the other hand, non-dipper hypertension is a risk factor for cardiac adverse events. The objective of this research was to determine whether the fQRS-T, a marker of ventricular heterogeneity, could be used to predict non-dipper hypertensive individuals in the lack of left ventricular hypertrophy. Methods: The observational study was carried out retrospectively. Patients diagnosed with hypertension were included in this study. Blood tests were routinely conducted for all patients. Electrocardiography (ECG) was conducted for each patient and echocardiography was performed. Blood pressure (BP) values were collected from the ambulatory Holter records. According to ambulatory Holter monitoring, the individuals were separated into two groups. The association between fQRS-T and hypertension was investigated. Results: The research involved 123 patients, with an average age of 51.85±8.22 years, comprising 76 women (61.8%) and 47 males (38.2%). According to ambulatory Holter monitoring, patients were separated into dippers (n=65) and non-dippers (n=58). There were no statistically significant in the laboratory and echocardiographic variables (p>0.05). QT dispersion (QTd) and fQRS-T were substantially greater in the non-dipper group than in the dipper group (p=0.043 and p<0.001, respectively). Independent determinants of non-dipper status were determined by univariate and multivariate logistic regression analyses. fQRS-T was found to be the only independent indicator of non-dipper status (OR: 1.03, 95%CI: 1.02-1.06, p<0.001). Conclusion: The fQRS-T may be a useful marker for estimating non-dipper hypertensive individuals in the lack of left ventricular hypertrophy.
Prevalence of Hypertension in Military Personnel: A Study Conducted in Türkiye
(2023) Günlü, Serhat; Karahan, Mehmet Zülkif
Abstract: Hypertension is a major global public health concern. There is a paucity of studies describing military populations with hypertension. We aimed to demonstrate Turkish military personnel with hypertension and review associated factors in a garrison of Diyarbakır City. This retrospective cross-sectional study comprised 22,141 individuals referred to an outpatient cardiology clinic between August 2016 and June 2022 with complaints of early morning headaches, abnormal heart rhythms, nosebleeds, visual problems, and buzzing in the ears. Sociodemographic characteristics were collected. Analyses of laboratory test findings and blood pressure measurements were conducted. The study comprised a total of 174 patients with an average age of 32.68±6.51 years. 94.8 percent of the patients were not drug users, and 68.3 percent had no strong family history. The prevalence of hydration habits (29.4%) and sleep disturbances (22.5%) were lower. According to body mass index (BMI), the rate of overweight was higher (56.8%). Most patients' educational status was bachelor’s degrees (46.5%). The smoking rate was high (73%). Body mass index was a statistically significant predictive factor of hypertension (OR [95% CI], 2.69 [1.0-7.17], p= 0.048). Physical exercise rate in the past three months was a statistically significant predictive factor for hypertension (OR [95%CI], 2.98 [1.42-6.23], P= 0.021). Hypertension was detected in 0.78 percent of all participants and was associated with being overweight and a lower frequency of physical exercise.

(ELSEVIER, 2023) Günlü, Serhat; Aktan, Adem; Kılıç, Raif; Günlü, Serhat; Arslan, Bayram; Arpa, Abdulkadir; Güzel, Hamdullah; Tatlı, İsmail; Aydın, Saadet; Suzan, Veysel; Demir, Muhammed
Background 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.

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
Objective: 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.
Atriyal Fibrilasyonda Kanama Riski Belirleme
(2023) Kayan, Fethullah
GİRİŞ 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 edilebilir

Evaluation 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
Background: 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

Evaluation 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
Although transcatheter aortic valve replacement (TAVR) is safe and effective, mortality and bleeding events post procedure are important. 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.
Predicting the mortality in patients with carotid artery stenosis by monocyte to high density lipoprotein ratio
(2023) Günlü, Serhat
Introduction: Background: Monocytes, which produce a variety of cytokines and molecules, interact with platelets and endothelial cells, causing inflammatory and thrombotic pathways to become worse. Macrophage migration and oxidation of low-density lipoprotein cholesterol molecules are both inhibited by high-density lipoprotein cholesterol (HDL-C). HDL-C neutralizes monocytes' pro-inflammatory and pro-oxidant effects through several mechanisms. As a result, characteristics like the monocyte to HDL-C ratio (MHR) may reveal a patient's inflammatory status. Objective: The development of carotid artery stenosis (CAS) is influenced by inflammation, oxidative stress, and endothelial dysfunction. Recent research suggests that inflammatory biomarkers are important for assessing mortality in carotid artery stenosis. This study aims to determine the association between MHR and mortality after carotid artery stenting. Tools and Method: We enrolled 260 patients with CAS who underwent carotid artery stenting between 2019 and 2021. MHR was calculated using the formula: the monocyte value dividing by the high-density lipoprotein cholesterol value. According to 30-day mortality, the patients were divided into two groups; surviving and non-surviving. Monocyte counts, HDL-C, and MHR values were compared between the groups. Results: The patient group had significantly higher monocyte counts and lower HDL levels than the control group, resulting in higher MHR values. In addition, non-surviving patients had a higher monocyte count and MHR value, as well as a lower HDL-C level (p<0.001). In patients with CAS, the MHR value was also found to be a significant independent determinant of 30-day mortality (p<0.001). MHR had the optimum cut-off value of 17.52 with 78.3% sensitivity and 83.4% specificity (AUC:0.724, p<0.001) for predicting 30-day mortality in patients with CAS. Comparison of the monocyte count, HDL level, and MHR value according to the mortality within the 30 days. Non-surviving group n=48 Surviving group n=212 P-values Monocyte (x109 µL) 915.42±53.21 524.03±9.98 <0.001 HDL-C (mg/dL) 37.03±1.16 46.22±0.9 <0.001 MHR 18.86±5.25 12.21±2.21 <0.001 Values are presented as mean ± SD and median [interquartile range]. HDL-C; high-density lipoprotein cholesterol, MHR; monocyte to high-density lipoprotein ratio. Discussion: Conclusion: In patients with CAS, a high MHR value was found to be an independent predictor of 30-day mortality.
Akut Kalp Yetmezliğinde Tedavi Yaklaşımı
(AKADEMİSYEN, 2023) Günlü, Serhat
GIRIŞ 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).

GİRİŞ Miyokardit, öncelikle çocukları ve genç yetişkin- leri etkileyen, nadir görülen, potansiyel olarak ölümcül ve genellikle yetersiz teşhis edilen bir kalp yetmezliği nedenidir. Akut miyokardit insidansı küresel olarak yılda yaklaşık 1,5 milyon vaka olarak tahmin edilmek- tedir (1). Miyokardit, asemptomatik olabileceği gibi kalp nakli gerektirebilecek kadar ileri derecede kalp yetmezliğine neden olabilen çok geniş bir klinik yelpazeye sahiptir. Bu sebeple miyokardit, klinik prezentasyonunun heterojenliği nedeniyle zor bir tanıdır. Miyokarditin kalp yetmezliği (Heart Failu- re-HF) nedeni olarak katkısı, yaşa ve bölgeye göre yaklaşık olarak % 0.5 ila % 4.0 arasında değişir (2). Açıklanamayan non-iskemik dilate kardiyomi- yopatisi (DKM) olan yetişkin hastaların %9-16’sın- dan sorumlu olduğu düşünülmektedir.

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
Background/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.
Diyastolik Disfonksiyon Tanısında Elektrokardiyografik Diyastolik Endeksinin Prognostik Rolü
(2023) Günlü, Serhat
Amaç: 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.
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
Background: 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.

Relationship Between Atrial Fibrillation Recurrence and Frontal QRS-T Angle After Effective Cardioversion
(Cureus, 2023) Karahan, Mehmet Zülkif; Karahan, Mehmet Zülkif
Objective: Maintaining sinus rhythm is important in the management of atrial fibrillation (AF). After cardioversion, there is a significant probability of AF recurrence. There is limited research on the relationship between AF recurrence and ECG parameters. This study aimed to evaluate whether the frontal plane QRS-T angle (fQRS-T), a predictor of ventricular heterogeneity, could be used to predict AF recurrence following cardioversion. Methods: The study was conducted as a retrospective observational study. Patients diagnosed with acuteonset AF for the first time were included in the study. All patients underwent an ECG after cardioversion, and ECG parameters were evaluated. The patients were separated into two groups based on the presence of AF recurrence during hospitalization after cardioversion. The relationship between the fQRS-T and AF recurrence was also examined. Results: A total of 162 patients, comprising 68 women (41.9%) and 94 men (58.1%) with an average age of 59.4±6.5 years, were enrolled in the research. Based on the patient monitoring device findings, patients were separated into two groups: non-recurrent AF (n=118) and recurrent AF (n=44). P-wave duration was significantly longer in the recurrence group (p=0.009). The recurrence group's mean fQRS-T was significantly higher (p<0.001). AF recurrence was substantially higher in patients with fQRS-T >90 ̊compared to those with fQRS-T ≤90 ̊(56.1% vs. 14.2%, p <0.001). Increased fQRS-T >93.7 ̊indicated AF recurrence with 78.3% sensitivity and 83.4% specificity (AUC {area under curve}:0.748, p < 0.001). In multivariate analysis, fQRS-T was revealed to be an early indicator of recurrent AF (OR: 1.882, 95%CI: 1.358-2.881, p<0.001). Conclusion: The fQRS-T, an easily determinable parameter from automatic identification ECG recordings, may be useful for predicting the early return of AF after successful cardioversion.
Transradial Approach in Coronary Angiography from Past to Present
(2023) Günlü, Serhat
The transradial approach is a novel method for coronary angiography and percutaneous coronary intervention. Its popularity has grown since its initial application and is now a common technique in many facilities. This is because the transradial approach is less invasive than the conventional approach, which requires catheter placement into the coronary arteries. Transradial access is safer than trans-femoral access because it results in fewer complications at the interventional site, requires a shorter hospital stay, enables the patient to be mobilized sooner, provides a higher degree of patient comfort, and carries a lower risk of significant bleeding events. This research examines the advantages of accessing coronary arteries through the radial artery, as well as the suggestions made by the guidelines and the challenges generated by the technique. All these issues were discussed in light of existing studies.
