    Background: Deteriorated aortic elasticity is part of the atherosclerotic process. Inflammation is an underlying factor in both COVID-19 and atherosclerosis. Aims and Objectives: Using aortic elastic properties, we aimed to assess the subclinical indicators of susceptibility to inflammatory atherosclerosis in patients with COVID-19. Materials and Methods: Out of 194 participants included in this study, 100 were diagnosed with COVID-19 in the last 6 months (60 women and 40 men with a mean age of 34.13 ± 6.45 years) and 94 were healthy controls (55 women and 39 men with a mean age of 30.39 ± 7.21 years). We analyzed transthoracic echocardiographic and aortic stiffness parameters in all participants. Results: Values of systolic blood pressure (110 [85-140] vs. 110 [80-140], P = 0.037) and pulse pressure (PP) (37 [25-55] vs. 40 [25-55], P < 0.01) were significantly different between the groups. As for laboratory parameters, levels of glucose (97.89 ± 20.23 vs. 92.00 ± 9.95, P = 0.003) and creatinine (0.80 ± 0.13 vs. 0.75 ± 0.09, P = 0.003) were significantly higher in the COVID-19 group. Echocardiographic parameters showed that both groups differed significantly in diastolic aortic diameter (2.42 ± 0.28 vs. 2.31 ± 0.35, P = 0.017), aortic strain (9.66 [1.20-31.82] vs. 12.82 [2.41-40.11], P = 0.025), aortic distensibility (0.502 [0.049-2.545] vs. 0.780 [0.120-2.674], P < 0.01), and aortic stiffness (16.67 [4.19-139.43] vs. 11.71 [3.43-65.21], P = 0.006). Conclusion: Measurement of aortic stiffness is a simple, practical yet inexpensive method in COVID-19 patients, and therefore, may be used as an early marker for COVID-19-induced subclinical atherosclerosis. © 2022 Wolters Kluwer Medknow Publications.

    P-wave duration and dispersion in lone obesity
    (College of Physicians and Surgeons Pakistan, 2021) Cosgun, Mehmet; Sincer, Isa; Inanir, Mehmet; Erdal, Emrah; Mansiroglu, Asli Kurtar; Gunes, Yilmaz
    Objective: To assess P-wave duration and dispersion (PD) in morbidly obese young subjects who do not have co-associated atrial fibrillation (AF) risk factors, such as hypertension, diabetes, atrial enlargement and diastolic dysfunction. Study Design: An observational cross-sectional study. Place and Duration of Study: Bolu Abant Izzet Baysal University Medical Faculty, Turkey; and the study was conducted between October 2017 and June 2018. Methodology: P-wave duration and dispersions were determined on 12-lead surface ECG in 47 morbidly obese and 44 healthy weight subjects, aged between 21-40 years. Above mentioned risk factors were studied. The correlation between BMI, PD and Pmax were investigated by Pearson correlation analysis. Results: Average body mass index (BMI) of obese and control groups were 42.3 (8.5) vs. 19.5 (1.5) (P <0.001). Maximum P-wave duration [(Pmax), 105.3±9.8 vs. 95.6±8.5, p<0.001] and PD [27.6 (7.6) vs. 12.2(8.3), p<0.001] were statistically significantly prolonged in obese patients when compared to the normal weight group. BMI correlation with Pmax and PD (r=0.485; p<0.001 and r=0.620; p<0.001, respectively) were significant. Conclusion: Pmax and PD, which are potential electrocardiographic AF predictors, may increase in lone obese patients having no comorbidities. © 2021 College of Physicians and Surgeons Pakistan.

    Serum uric acid to HDL-cholesterol ratio could be promising predictor of atrioventricular nodal reentrant tachycardia
    (2023) Donmez, Ibrahim; Cosgun, Mehmet; Bayraktar, Muhammed Fatih; Korkmaz, Ufuk Turan Kursat; Demirel, Mustafa Enes; Acar, Emrah; Gunes, Yilmaz
    Aim: Paroxysmal supraventricular tachycardia (PSVT), particularly atrioventricular nodal reentrant tachycardia (AVNRT), is a common arrhythmia with no associated structural heart disease. Inflammation has been implicated in the pathogenesis of arrhythmias. Uric acid to high density lipoprotein (HDL)-cholesterol ratio (UHR) is a novel inflammation marker that has been investigated in various conditions. This study aimed to explore the potential association between UHR and AVNRT. Materials and Methods: A total of 136 patients were included in the study, including 86 patients with AVNRT and 50 controls with normal electrophysiological study. All patients’ medical records were reviewed, and data were obtained retrospectively. We recorded baseline features, hematologic and biochemical markers, and determined the UHR value. Results: UHR (p=0.031) and uric acid (p<0.001) levels were significantly higher, while HDL cholesterol (p=0.031) levels were significantly lower in the AVNRT group. Neutrophil leukocyte ratio (NLR) was also higher in the AVNRT group (p=0.034). However, in multivariate analysis, only UHR emerged as an independent predictor for AVNRT (OR: 1.088; 95%CI: 1.022 – 1.159; p=0.008). ROC curve analysis suggested a UHR cut-off > 14.05 for predicting AVNRT with 56% sensitivity and 76% specificity. Conclusion: This study identifies UHR as a promising predictor for AVNRT, shedding light on the potential role of inflammation in the arrhythmia’s development. Utilizing UHR as a readily accessible marker in the evaluation of AVNRT patients may have clinical implications.
