Background: Atrial fibrillation (AF) is the most common rhythm disorder in the elderly. The AF can cause life-threatening thromboembolic complications. Therefore, there is a need to determine the risk factors of AF. In this study, we aimed to examine the association of markers of malnutrition with AF in individuals aged 75 years and older and to find the factors that may affect mortality. Methods: In this prospective study, 358 consecutive individuals aged 75 years and older presenting to the cardiology outpatient clinic were included. All participants were divided into AF and sinus rhythm (SR) groups. In addition, a questionnaire and scoring system were used to assess malnutrition status. Information was obtained from all patients through outpatient clinic visits or telephone interviews for one year. Death from any cause was considered as the endpoint. Results: AF was observed in 71 (19.8%) patients. Death was higher in patients with AF (p < 0.001), high CONUT score (p = 0.018), and GLIM malnutrition (p = 0.018). GLIM malnutrition caused a 2.8-fold increase in the development of AF. Conclusions: Screening for malnutrition in the elderly is essential. According to GLIM criteria, malnutrition may play a role in the development of AF and increase one-year mortality in the elderly.

Background: Atrial fibrillation (AF) is one of the most common heart rhythm disorders. Identification and early treatment of AF risk factors can improve mortality and morbidity rates. This study aimed to compare the renal venous stasis index (RVSI) and intra-renal venous flow (IRVF) patterns evaluated by intra-renal Doppler ultrasonography in patients with AF and sinus rhythm (SR).Material/Methods: A total of 68 patients, 34 with AF (lasting >12 months AF) and 34 with SR (no previous diagnosis of AF and no AF attack in 24-h Holter monitoring) were included in the study. The RVSI was calculated, and the IRVF patterns were determined using intra-renal Doppler ultrasonography. High RVSI was defined as >0.12 RVSI. In addition, echocardiography and a 6-min walk test were performed. A model including diabetes mellitus, hypertension, creatine, Pro-BNP, left ventricular ejection fraction, presence of AF, and systolic pulmonary artery pressure was created to evaluate the effects of variables on high RVSI.Results: The RVSI value was significantly higher in patients with AF than in those with SR (P=0.004). The SR group exhibited a higher prevalence of the continuous flow pattern, which is one of the IRVF patterns (P=0.015). In contrast, the biphasic flow pattern was observed more frequently in patients with AF (P=0.003). The presence of AF was found to predict the high RVSI (P=0.002, OR=14.134, 95% CI 2.083-71.277).Conclusions: The presence of AF may affect the IRVF and cause an increase in RVSI.

Background and Objectives: Smokeless tobacco (ST) use has recently become an alternative to cigarettes, and it has been concluded that ST is at least as harmful as cigarettes. ST use is thought to play a role in the pathogenesis of arrhythmia by affecting ventricular repolarization. In this study, we aimed to examine the relationships of Maras powder (MP), one of the ST varieties, with epicardial fat thickness and new ventricular repolarization parameters, which have not previously been described. Materials and Methods: A total of 289 male individuals were included in this study between April 2022 and December 2022. Three groups, 97 MP users, 97 smokers, and 95 healthy (non-tobacco), were compared according to electrocardiographic and echocardiographic data. Electrocardiograms (ECG) were evaluated with a magnifying glass by two expert cardiologists at a speed of 50 m/s. Epicardial fat thickness (EFT) was measured by echocardiography in the parasternal short- and long-axis images. A model was created with variables that could affect epicardial fat thickness. Results: There were no differences between the groups regarding body mass index (p = 0.672) and age (p = 0.306). The low-density lipoprotein value was higher in the MP user group (p = 0.003). The QT interval was similar between groups. Tp-e (p = 0.022), cTp-e (p = 0.013), Tp-e/QT (p =0.005), and Tp-e/cQT (p = 0.012) were higher in the MP user group. While the Tp-e/QT ratio did not affect EFT, MP predicted the epicardial fat thickness (p < 0.001, B = 0.522, 95%CI 0.272–0.773). Conclusions: Maras powder may play a role in ventricular arrhythmia by affecting EFT and causing an increase in the Tp-e interval.

Sol koroner arterin pulmoner arterden (ALCAPA) anormal kökeni, nadir görülen doğuştan kalp anomalisidir. Genellikle klinik seyir; ileri sol kalp yetmezliği ve yaşamın ilk aylarında ortaya çıkan mitral kapak yetersizliğidir. Bununla birlikte, bazı durumlarda sağ koroner arterden oluşan kollateraller miyokard perfüzyonu için yeterlidir. ALCAPA'lı hastalarda aritmi veya erişkin yaşamda ani kalp ölümü ilk klinik başvuru olabilir. Göğüs ağrısı ve çarpıntı şikayetleri ile acil servise başvuran ve sol koroner arterde anormal köken saptanan 66 yaşında kadın hastayı sunmaktayız.
