RESUMO

The identification of interatrial block (IAB) through electrocardiography (ECG) has been correlated with an elevated likelihood of developing atrial fibrillation (AF) and stroke. IAB is diagnosed by evaluating P-wave prolongation on a surface ECG. The presystolic wave (PSW) is an echocardiographic marker determined by pulse-wave examination of the aortic root during late diastole. As IAB and PSW share similar pathophysiological mechanisms, we speculated that PSW, as a component of the P wave, might be useful in predicting IAB. In the present study, we aimed to determine the relationship between PSW and IAB. Patients with pre-diagnosis of supraventricular tachycardia (SVT) on electrocardiography or rhythm Holter monitoring between January 2021 and December 2022 were included in the study. Surface 12-lead ECG and transthoracic echocardiography (TTE) were performed for the diagnosis of IAB and PSW. Patients were divided into two groups based on the presence of IAB, and PSW was compared between the groups. In total, 104 patients were enrolled in this study. IAB was diagnosed in 16 patients (15.3%) and PSW was detected in 33 patients (31.7%). The PSW was higher in the IAB ( +) group than in the IAB ( -) group (10 patients (71.4%) vs. 23 patients (32.4%), p = 0.008). PSW may be a useful tool for predicting IAB in patients with SVT. Further studies are needed to determine the clinical utility of PSW in the diagnosis and management of IAB.

RESUMO

AIM: Hepatic fibrosis, a progressive scarring of liver tissue, is commonly caused by non-alcoholic fatty liver disease (NAFLD), which increases the risk of cardiovascular disease. The Fibrosis-4 (FIB-4) index is a non-invasive tool used to assess liver fibrosis in patients with NAFLD. Aortic valve sclerosis (AVS), a degenerative disorder characterized by thickening and calcification of valve leaflets, is prevalent in the elderly and associated with increased cardiovascular morbidity and mortality. Recent studies have suggested that AVS may also be linked to other systemic diseases such as liver fibrosis. This study aimed to investigate the relationship between the FIB-4 index and AVS in a non-alcoholic population, with the hypothesis that the FIB-4 index could serve as a potential marker for AVS. METHOD: A total of 92 patients were included in this study. AVS was detected using transthoracic echocardiography, and patients were divided into groups according to the presence of AVS. The FIB-4 index was calculated for all patients and compared between the groups. RESULTS: A total of 17 (18.4%) patients were diagnosed AVS. Patients with AVS had higher rates of diabetes mellitus, older age, hypertension, angiotensin-converting enzyme inhibitor use, higher systolic blood pressure (BP) and diastolic BP in the office, coronary artery disease prevalence, left atrial volume index (LAVI), left ventricular mass index (LVMI), and late diastolic peak flow velocity (A) compared to those without AVS. Moreover, AVS patients had significantly higher creatinine levels and lower estimated glomerular filtration rate. Remarkably, the FIB-4 index was significantly higher in patients with AVS. In univariate and multivariate analyses, higher systolic BP in the office (OR, 1.044; 95% CI 1.002-1.080, p = .024) and higher FIB-4 index (1.46 ± .6 vs. .91 ± .46, p < .001) were independently associated with AVS. CONCLUSION: Our findings suggest that the FIB-4 index is associated with AVS in non-alcoholic individuals. Our results highlight the potential utility of the FIB-4 index as a non-invasive tool for identifying individuals at an increased risk of developing AVS.

RESUMO

AIM: Ascending aortic dilatation is a common clinical issue. In the present study, we aimed to evaluate the relationship between ascending aortic diameter with left ventricular (LV) and left atrial (LA) functions, and LV mass index (LVMI) in a population with normal LV systolic function. METHODS: A total of 127 healthy participants with normal LV systolic function took part in the study. Echocardiographic measurements were obtained from each subject. RESULTS: The mean age of the participants was 43 ± 14.1 years and 76 (59.8%) were female. The mean aortic diameter of the participants was 32.2 ± 4.7 mm. A negative correlation was found between aortic diameter and LV systolic function (LVEF r = -.516, p < .001; Gls r = -.370). In addition, there was a strong positive correlation between aortic diameter with LV wall thicknesses, LVMI (r = .745, p < .001), and systolic and diastolic diameters. The relationship between aortic diameter and diastolic parameters was evaluated, a negative correlation with Mitral E, Em, E/A ratio, and a positive correlation with MPI, Mitral A, Am, E/Em ratio were found. CONCLUSION: A strong correlation between ascending aortic diameter with LV and LA functions, and LVMI in individuals with normal LV systolic function.

RESUMO

Objective. Aortic valve sclerosis (AVS) is closely related to endothelial dysfunction. The association of AVS with contrast-induced nephropathy (CIN) is unknown. We planned to investigate the relationship of AVS besides known parameters with CIN. Design. Baseline characteristics, biochemical values, and AVS of 292 consecutive patients with acute coronary syndrome (ACS) that underwent percutaneous coronary intervention (PCI) were analyzed. Results. Fifty-three patients (18.2%) had CIN. Patients with CIN were older, less likely to be smokers, and had more prevalent prior bypass surgery, higher Mehran score, creatinine, and uric acid concentrations than those without CIN. AVS was more prevalent in patients with CIN. Logistic regression analysis including all related parameters identified Mehran score (OR = 1.036, p = .033), uric acid concentration (OR = 1.244, p = .023), and AVS (OR: 2.223, p = .027) as independent predictors of CIN. Conclusion. AVS is independently associated with CIN in patients with acute coronary syndrome undergoing percutaneous coronary intervention. AVS may help to identify high-risk patients for CIN, who would benefit from preventive measures.

RESUMO

Background: YKL-40 (human cartilage glycoprotein 39, chitinase-3-like protein 1) is an inflammatory marker secreted mainly by macrophages and has distinctive roles on extracellular matrix remodeling, macrophage maturation, adhesion, and migration. Despite the presence of robust data suggesting the association of YKL-40 with variety of cardiovascular diseases (CV), there is no study up to date evaluating the role of YKL-40 on the long-term prognosis in patients with hypertension (HT).Methods: A single center, prospective, observational cohort study that included 327 consecutive hypertensive patients which were presented to a cardiology outpatient clinic. Patients were followed up for 7.89 ± 0.12 years. Primary outcome of the study was the occurrence of major cardiovascular outcomes (MACE) defined as all-cause mortality, new onset heart failure (HF), and coronary artery disease (CAD) requiring revascularization.Results: A total of 135 patients constituted the final study population [mean age: 52.4 ± 10.2, female: 63 (46%)]. A total of 28 (20.7%) patients had MACE during the follow up. Cox regression analysis revealed that age (HR: 1.046, 1.016-1.093 CI 95%, p = .026), diabetes (HR: 2.278, 1.026-5.057 CI 95%, p = .043), and YKL-40 level (HR: 1.019, 1.013-1.026 CI 95%, p = .005) significantly predicted MACE. We found that sensitivity and specificity of YKL-40 > 93.5 for predicting MACE was 71.4% and 65%, respectively with an area under curve (AUC) 0.723 (0.617-0.828 CI 95%, p < .001)Conclusion: Elevated serum YKL-40 level predicted MACE in hypertensive patients during a long-term follow up.

RESUMO

OBJECTIVE: Atrial fibrillation (AF) is a common arrhythmia that increases morbidity and mortality, as well as healthcare costs. The induction of AF (IAF) during programmed atrial pacing in an electrophysiological study (EPS) is a prevalent phenomenon that has been underappreciated by electrophysiologists. Despite extensive research on AF, only a few studies have focused on this phenomenon. The aim of our study was to investigate the association between history of AF and IAF and the underlying pathophysiological factors such as arterial stiffness, subclinical atherosclerosis, and impaired endothelial function. METHODS: This cross-sectional and observational study included 87 patients who had palpitations and were scheduled for EPS. Patients underwent biochemical investigations, transthoracic echocardiography, carotid ultrasound, carotid-femoral artery pulse wave velocity (PWV), and flow-mediated dilatation (FMD) measurements before EPS. Patients were divided into two groups, AF-induced and non-induced in EPS, for further statistical analysis. RESULTS: AF was induced in 16 of 87 patients (18.3%) included in the analysis. The FMD (%) was significantly lower (16.01 ± 10.1 vs. 8.7 ± 5.7, P = 0.022) and, remarkably, the proportion of patients with a history of AF was significantly higher (2.8% vs. 37.5%, P < 0.001) in the IAF group. ROC analysis showed that a documented AF and FMD predicted IAF, with AUC of 0.741 (p = 0.012) and 0.740 (p = 0.001), respectively. Logistic regression analysis revealed that FMD and history of AF were strong predictors of IAF (odds ratio [OR], 0.853; 95% confidence interval [CI] 0.737-0.988; P = 0.034, OR: 10.1, 95% CI 4.9-20.5; P = 0.003, respectively). CONCLUSION: Endothelial dysfunction and documented AF were associated with IAF during EPS.

RESUMO

BACKGROUND AND AIMS: Non-alcoholic fatty liver disease (NAFLD) is related to an increased atherosclerotic cardiovascular disease (ASCVD) risk. This study investigated a potential relationship between liver fibrosis scores (LFS) reflecting NAFLD and ascending aortic dilatation (AAD). METHODS: This is an observational and cross-sectional study. Patients were consecutively enrolled from a cardiology clinic. The NAFLD fibrosis score (NFS), fibrosis-4 (FIB-4) index, aspartate aminotransferase (AST) to platelet ratio (APRI), and BARD scores of each patient were calculated. The ascending aortic diameters were evaluated by transthoracic echocardiography according to current clinical guidelines. The patients were allocated into two groups with and without AAD. RESULTS: A total of 272 patients were included in the study. In AAD group, age, patients with hypertension (HT), coronary artery disease (CAD), FIB-4 index, BARD score and the NFS were significantly higher. As compared to the AAD group, body mass index (BMI), hemoglobin, and diuretic use were significantly higher in patients without aortic dilatation. The NFS with AAD, and NFS and FIB-4 index with indexed aortic diameter (AI) showed significant positive correlation (R=0.546, R=0.332, R=0.314 with p<0.001, respectively). In multivariate logistic regression analysis hemoglobin levels (OR=0.728, 95%CI: 0.553-0.958; p=0.023), BMI (OR=0.762, 95%CI: 0.668-0.869, p<0.001), HT (OR=3.269, 95%CI: 1.045-10.220; p=0.042), BARD score (OR=1.248, 95%CIL 0.815-1.955; p=0.044), and FIB-4 index (OR=2.432, 95%CI: 1.395-4.246; p=0.002) were found to be independently related to AAD. CONCLUSIONS: Our study demonstrated a statistically significant relationship between NFS, FIB-4 index, BARD score and AAD. The presence of positive correlation among LFS and AAD in our study is remarkable. This may emphasize the increased risk of AAD in NAFLD.

RESUMO

PURPOSE: In cases of testicular torsion (TT), prompt diagnosis and treatment are highly associated with organ salvage, and manual detorsion (MD) is a recommended maneuver as a first intervention. In our study, we aimed to investigate the effect of predictive factors of TT in predicting the success of MD. METHODS: A retrospective, 2-center study was conducted on patients diagnosed with TT between January 2015 and 2024. Demographic, clinical, ultrasound, and laboratory characteristics at presentation were analyzed. MD was routinely performed as the first intervention in all patients. Predictive parameters were compared in the MD success and failure groups. Univariate and multiple logistic regression analysis was used to identify risk factors for MD failure. RESULTS: A total of 94 patients were included in the study. The median age of the patients was 20 (IQR: 12-69) years, and the median symptom duration was 6 (IQR: 4-12) hours. MD confirmed by Doppler ultrasonography was successful in 52 (55.3%) patients and unsuccessful in 42 (44.7%). Age, symptom duration, Testicular Workup for Ischemia and Suspected Torsion (TWIST) score, TWIST risk groups, WBC, neutrophil, monocyte counts, and Monocyte/Eosinophil ratio (MER) were statistically different between the two groups. In multiple logistic regression analysis, the risk factors for failure of MD were found to be being over 18 years of age, the duration of symptoms being longer than 9 h, and MER > 28. CONCLUSION: Current urology guidelines suggest that age, symptom duration, and MER are reliable predictors of the success of MD, which is recommended in all cases of TT.

RESUMO

BACKGROUND: Non-alcoholic Fatty Liver Disease (NAFLD) is a widespread liver disorder caused by excess fat accumulation in the liver with no significant alcohol consumption. This condition has been linked to the development of cardiovascular diseases (CVD) and atherosclerosis. Carotid intima-media thickness (CIMT) and carotid plaques, which are established markers of subclinical atherosclerosis, were used to assess CVD risk. However, few studies have explored the correlation between NAFLD and subclinical atherosclerosis, especially in young and middle-aged men. A study on 200 male patients aged 18-55 years aimed to investigate the association between NAFLD fibrosis score (NFS) and CIMT, as well as carotid plaque presence. METHODS: The study, conducted between July 2023 and January 2024, included CIMT measurements and plaque assessments performed using B-mode ultrasound. Participants were divided into two groups based on CIMT values and plaque presence, and NFS was analyzed for its association with CIMT and plaque. RESULTS: Participants with higher CIMT values had a significantly higher NFS (-2.9 ± 1.13 vs. -1.9 ± 1.4, P < 0.001) than those with lower CIMT values. Similarly, participants with carotid plaque also exhibited a higher NFS (-2.5 ± 1.3 vs. -1.7 ± 1.4, P = 0.002). Multivariate logistic regression analysis showed that NFS was a strong predictor of both increased CIMT (odds ratio [OR]: 1.564%95 CI 1.035-2.363; P = 0.034) and carotid plaque presence (OR: 1.605%95 CI 1.118-2.290; P = 0.010). CONCLUSION: These results emphasize the potential role of NFS as a marker of subclinical atherosclerosis in young and middle-aged men.

RESUMO

Non-alcoholic faty liver disease (NAFLD) and liver fibrosis score (FIB 4) are associated with increased mortality from cardiovascular causes. NAFLD and cardiac diseases are different manifestations of systemic metabolic syndrome. In this study, we aimed to reveal the relationship between NAFLD and FIB 4 liver fibrosis scores and mitral annular calcification (MAC). One hundred patients were included in the study. Blood samples and echocardiography measurements were obtained from each subject. The two groups were compared in terms of demographic and echocardiographic characteristics. Thirty-one men and 69 women with a mean age of 48.6 ± 13.1 years were included in the analysis. The patients were divided into two groups as those with MAC (n = 26) and those without (n = 74). The baseline demographic and laboratory data for the two groups were compared. In the group with MAC (+) age, serum creatinine levels, FIB4 and NAFLD Scores; HL, DM rates, angiotensin converting enzyme (ACE) inhibitor and statin usage rates were higher, with statistical significance. NAFLD and FIB 4 liver fibrosis scores have an independent relationship with MAC.

RESUMO

The prevalence of penile calcification in the population remains uncertain. This retrospective multicenter study aimed to determine the prevalence and characteristics of penile calcification in a large cohort of male patients undergoing non-contrast pelvic tomography. A total of 14 545 scans obtained from 19 participating centers between 2016 and 2022 were retrospectively analyzed within a 3-months period. Eligible scans (n = 12 709) were included in the analysis. Patient age, penile imaging status, presence of calcified plaque, and plaque measurements were recorded. Statistical analysis was performed to assess the relationships between calcified plaque, patient age, plaque characteristics, and plaque location. Among the analyzed scans, 767 (6.04%) patients were found to have at least one calcified plaque. Patients with calcified plaque had a significantly higher median age (64 years (IQR 56-72)) compared to those with normal penile evaluation (49 years (IQR 36-60) (p < 0.001). Of the patients with calcified plaque, 46.4% had only one plaque, while 53.6% had multiple plaques. There was a positive correlation between age and the number of plaques (r = 0.31, p < 0.001). The average dimensions of the calcified plaques were as follows: width: 3.9 ± 5 mm, length: 5.3 ± 5.2 mm, height: 3.5 ± 3.2 mm, with an average plaque area of 29 ± 165 mm² and mean plaque volume of 269 ± 3187 mm³. Plaques were predominantly located in the proximal and mid-penile regions (44.1% and 40.5%, respectively), with 77.7% located on the dorsal side of the penis. The hardness level of plaques, assessed by Hounsfield units, median of 362 (IQR 250-487) (range: 100-1400). Patients with multiple plaques had significantly higher Hounsfield unit values compared to those with a single plaque (p = 0.003). Our study revealed that patients with calcified plaques are older and have multiple plaques predominantly located on the dorsal and proximal side of the penis.

RESUMO

Voiding symptoms and penoscrotal mass with/without fistula are typical findings of urethral diverticulum. We present a case of 55-year-old male patient who was evaluated for voiding symptoms, soft palpable penoscrotal mass and fistula. Retrograde urethrography, scrotal ultrasonography and cystoscopy revealed a urethral diverticulum and fistula. The defect developed after excision of the diverticulum associated with the penile ventral urethra was closed with a penile skin flap. In the 6-month follow-up, the patient did not have any voiding complaints and no signs of recurrence. Urethroplasty using a penile skin flap may be preferred in the repair of penile ventral urethral defect.

RESUMO

Penetrating or blunt traumas can rarely lead to renal artery pseudoaneurysms (RAPs). Renal parenchymal lacerations usually accompany them, and nephrectomy is performed in these cases. Although angioembolization of the renal artery can negate the need for nephrectomy while treating the RAP, it is not a nephron-sparing procedure. Herein, we present a case of isolated (i.e. without accompanying renal laceration) left RAP. During conservative follow-up, the RAP enlarged, and subsequently, it was treated by renal artery stent insertion. An expandable covered stent was used during this procedure. The renal function was preserved without experiencing any complications.

RESUMO

BACKGROUND: Arterial hypertension is associated with cardiovascular morbidity and mortality. It was previously shown that left atrium volume increase associated with mortality and atherosclerotic heart disease. The aim of the present study was to demonstrate the value of endothelial dysfunction in predicting left atrium volume increase in newly diagnosed hypertension patients. METHODS: This study included 96 consecutive newly diagnosed hypertensive patients. Left atrium volume and left ventricular ejection fraction were calculated. Pulse wave velocity and brachial artery flow-mediated dilation measurements were obtained from each patient. RESULTS: Left Ventricle Mass Index (114 ± 29 g/m, 91 ± 17 g/m, P < 001), left ventricular septum (P < 0.001) and posterior wall thickness (P = 0.001), left ventricular end diastolic diameter (P = 0.016) were significantly higher in patients with higher left atrial volume index. FMD% was lower in patients with higher left atrial volume index those without (9.7 ± 3.5 vs. 13.31 ± 6.01, P = 0.004). Lateral wall E wave velocity was significantly lower (8.68 ± 2.8, 10.2 ± 2.8; P = 0.009), while isovolumetric relaxation time (101.9 ± 19.9 ms, 85.7 ± 15.2 ms; P < 0.001), and ejection time was longer (101.9 ± 19.9 ms, 85.7 ± 15.2 ms; P = 0.077) and Mitral E/ lateral wall E ratio (E/E relation) was significantly higher (P = 0.031) in patients with higher left atrial volume index. CONCLUSION: The rate of isovolumetric relaxation time, FMD% and E/E' ratio independently predicted left atrial volume index increase in newly diagnosed hypertension patients.

RESUMO

Left atrial function has an important role in determining optimal performance of the heart. Increase of left atrial dysfunction and volume are poor prognostic factors. In this study, we investigated independent determinants of left atrial function in non-diabetic patients with de novo hypertension. The study included 124 consecutive non-diabetic patients with de novo hypertension. Brachial artery flow-mediated dilatation, carotid intima-media thickness, transthoracic echocardiography, 24-h rhythm holter, and aortic stiffness measurements were recorded. In echocardiography, left atrial maximum (LAMaV) and minimum (LAMiV) volumes were calculated. Left atrium total emptying fraction (LATEF) and total emptying volume (LATEV) were divided into two groups according to the mean levels. Multivariate analysis was performed after correlation analysis for LATEV and LATEF mean levels. By logistic regression analysis, systolic blood pressure (OR 0.882, 95% CI 0.784-0.992, p = 0.036), percent of flow-mediated dilation (OR 0.747, 95% CI 0.595-0.938, p = 0.012), and presence of carotid plaque (OR 0.014, 95% CI 0.001-0.188, p = 0.001) were found as independent variables that determine LATEF. Age (OR 0.879, 95% CI 0.795-0.972, p = 0.012), smoking (OR 23.739, 95% CI 2.699-208.810, p = 0.004), left ventricular mass index (OR 1.052, 95% CI 1.012-1.094, p = 0.011), mitrale E-wave velocity (OR 1.108, 95% CI 1.031-1.191, p = 0.005) and LDL (low-density lipoprotein) cholesterol (OR 0.942, 95% CI 0.911-0.974, p = 0.001) were independent predictors of LATEV. In non-diabetic patients with de novo hypertension endothelial dysfunction, subclinical atherosclerosis and LDL cholesterol levels independently affect left atrial function.
