Fractal characteristics of the trabecular pattern of the mandible in patients with renal transplantation.

OBJECTIVE: In this study, we examined the mandibular trabecular bone structures by performing fractal dimension (FD) analysis in patients who underwent renal transplantation (RTx). METHODS: Our study is an observational study with 69 RTx patients and 35 control group patients. The mean FD values of the patient and control groups were calculated and compared. In addition, biochemical parathyroid hormone (PTH), serum calcium, phosphorus, alkaline phosphatase (ALP), and vitamin-D parameters and FD values of both groups were analyzed. RESULTS: FD values were significantly lower in the patient group than in the healthy group (p < .05). In the RTx group compared to the control group, ALP (90.71 ± 34.25-66.54 ± 16.8, respectively) (p < .001) and PTH (75.76 ± 38.01-38.17 ± 12.39, respectively) (p < .001) values were higher. There was a positive correlation between the FD values and ALP (rspearman  = .305, p = .011) and a negative correlation between FD values and vitamin-D (rspearman  = .287, p = .017) of patients with RTx. CONCLUSION: FD values were found to be lower in patients who underwent RTx compared to the control group. It should be considered that FD analysis can be a method that can be used to evaluate trabecular bone structure in patients undergoing RTx.

Presystolic wave as a predictor of interatrial block in patients with supraventricular tachycardia.

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.

FIB-4 liver fibrosis index correlates with aortic valve sclerosis in non-alcoholic population.

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.

A case of Guillain-Barré syndrome related to COVID-19 infection.

BACKGROUND: After the first COVID-19 case, reported neurological complications are increasing day by day. METHOD: In this paper, we present a benign-course Guillain-Barré syndrome (GBS) emerging 2 weeks after COVID-19 infection in a 35-years-old male. RESULTS: Cough and fever were started 18 days ago and his PCR test was resulted positive for COVID-19 infection. After treatment and quarantine were completed, he developed sudden leg weakness following autonomic features. Cerebrospinal fluid was suggestive for GBS despite the electrodiagnostic test was not helpful because it was done in the first days. He recovered without needing any immunotherapy. CONCLUSION: Our case suggested that COVID-19 can cause atypical benign GBS forms in addition to well-known variants. Comprehensive studies are needed to describe the unknowns and determine the exact prevalence of GBS after COVID-19 infection, including mild cases that did not require hospital admission.

The relationship between epicardial adipose tissue thickness and coronary artery disease progress.

BACKGROUND: The relationship between epicardial adipose tissue and inflammatory events has been shown in many studies. Because it is an inflammatory process in coronary progression, it is aimed to examine the relationship between coronary artery disease progression and epicardial adipose tissue thickness. MATERIALS AND METHODS: Our research was conducted with 50 patients (33 men, 17 women) who underwent planned or emergency coronary angiography, by evaluating the coronary artery disease progression from the coronary angiography images together with the echocardiographic epicardial adipose tissue thickness measurement. Patients were examined in two groups according to their tissue thickness, 17 patients with less than 0.55 cm were defined as group 1 and 33 patients with ≥ 0.55 were determined as group 2. RESULTS: There was no significant difference between the groups in terms of gender, diabetes, age, hypertension. In addition, a significant relationship was found with epicardial adipose tissue thickness (> 0.5 cm), ejection fraction and smoking in the group with coronary progression. Patients without stenotic changes were found to be statistically significantly lower p < 0.005. CONCLUSION: An independent relationship was found between epicardial adipose tissue and coronary artery progression. In the light of these findings, it can be concluded that epicardial adipose tissue residue is effective in the development of coronary artery stenosis and calcific-atherosclerotic changes in the coronary arteries. In the light of the information obtained, a positive correlation was determined between epicardial adipose tissue thickness and coronary artery disease (Tab. 3, Fig. 2, Ref. 15).

Quantitative assessment of left atrial functions by speckle tracking echocardiography in hypertensive patients with and without retinopathy.

PURPOSE: The association between hypertensive retinopathy and left atrial (LA) impairment is unknown. Accordingly, it was aimed to investigate the possible relationship between hypertensive retinopathy and LA phasic functions by means of two-dimensional speckle-tracking echocardiography (2D-STE). METHODS: A total of 124 hypertensive patients and 27 control subjects were included in the study. LA reservoir strain (LAS-S ), LA conduit strain (LAS-E ), and LA booster strain (LAS-A ) parameters were used to evaluate LA myocardial functions. RESULTS: Hypertensive patients (with and without retinopathy) displayed an obvious reduction in the LA reservoir strain (LAS-S ), and LA conduit strain (LAS-E ). Moreover, further impairment in LA reservoir and conduit strain was found in patients with hypertensive retinopathy than in the isolated hypertensive patients. There were no significant differences in LA booster strain (LAS-A ) among the three groups. Impaired LAS-S (OR: 0.764, CI: 0.657-0.888, and p < 0.001), LAS-E (OR: 0.754, CI: 0.634-0.897, and p = 0.001), and hypertension (HT) duration (OR: 2.345, CI: 1.568-3.507, and p < 0.001) were shown to be independent predictors of hypertensive retinopathy. CONCLUSION: Impaired LA reservoir and conduit strain may be used to predict hypertensive patients at higher risk of developing hypertensive retinopathy, and to determine which patients should be followed more closely for hypertensive retinopathy.

Fragmented QRS predicted major adverse cardiovascular events in patients with coronary artery disease and percutaneous coronary intervention, 10-years of follow-up.

Aim    Identifying high-risk groups in patient with coronary artery disease (CAD) is critical for predicting future adverse events. fQRS has been shown to be related to major cardiovascular adverse events (MACE) in patients with CAD. However, predictive value of fQRS for more than 5 yrs has not been evaluated. This study examined the predictive value of fQRS in patients with CAD and percutaneous coronary intervention during a 10­yrs period.Material and methods    Patients with CAD and percutaneous coronary intervention between March 2007 and May 2009 were included the study. An electrocardiogram was recorded following percutaneous coronary intervention and analyzed for the presence of fQRS. The fQRS pattern was defined as an additional spike inside the QRS complexes of at least two consecutive leads. Patients were followed for 10 yrs. A MACE was all-cause mortality or new-onset decompensated heart failure. Patients were divided into two groups according to presence or absence of MACE, and their clinical variables were compared.Results    Of 1261 patients included in the study, MACE developed in 374 (29.6 %). MACE (+) patients were older (p<0.001), more likely to have diabetes mellitus (p=0.003), fQRS (p<0.001), and ST-elevated myocardial infarction (STEMI) (p<0.001). Multivariable Cox regression analysis revealed that age (p<0.001), STEMI (p=0.001), fQRS (p=0.017), and elevated serum creatinine (p=0.001) were independent predictors of MACE.Conclusion    The presence of fQRS predicted MACE during 10 yrs of follow-up of patients with CAD and percutaneous coronary intervention.

APACHE II score predicts in-hospital mortality more accurately than inflammatory indices in patients with acute coronary syndrome.

Aim    This study evaluated the prognostic ability of the APACHE II score and compared it with inflammatory indices in patients with acute coronary syndrome (ACS).Material and Methods    A total of 525 patients with ACS were retrospectively enrolled in the study. APACHE II scores were calculated and C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), and systemic immune-inflammatory index (SII) were recorded. The APACHE II score was compared with inflammatory indices for predicting in-hospital mortality.Results    Univariate logistic regression (LR) analysis showed that CRP, SII, NLR, ejection fraction, chronic kidney disease, gender, and APACHE II score were significant predictors of mortality. In multiple LR analysis, the APACHE II score was found to be a solitary, significant predictor of in-hospital mortality (OR: 1.201, 95 % CI: 1.122-1.285; p<0.001). In the Receiver Operating Characteristics curve, using a cut-off point of 16.5, the APACHE II score predicted in-hospital mortality with 70.4 % sensitivity and 92.9 % specificity.Conclusion    The APACHE II score may be used as a predictor of in-hospital mortality better than inflammatory markers in ACS patients.

Double somatic mismatch repair gene pathogenic variants as common as Lynch syndrome among endometrial cancer patients.

OBJECTIVE: Lynch syndrome is the most common cause of inherited endometrial cancer, attributable to germline pathogenic variants (PV) in mismatch repair (MMR) genes. Tumor microsatellite instability (MSI-high) and MMR IHC abnormalities are characteristics of Lynch syndrome. Double somatic MMR gene PV also cause MSI-high endometrial cancers. The aim of this study was to determine the relative frequency of Lynch syndrome and double somatic MMR PV. METHODS: 341 endometrial cancer patients enrolled in the Ohio Colorectal Cancer Prevention Initiative at The Ohio State University Comprehensive Cancer Center from 1/1/13-12/31/16. All tumors underwent immunohistochemical (IHC) staining for the four MMR proteins, MSI testing, and MLH1 methylation testing if the tumor was MMR-deficient (dMMR). Germline genetic testing for Lynch syndrome was undertaken for all cases with dMMR tumors lacking MLH1 methylation. Tumor sequencing followed if a germline MMR gene PV was not identified. RESULTS: Twenty-seven percent (91/341) of tumors were either MSI-high or had abnormal IHC indicating dMMR. As expected, most dMMR tumors had MLH1 methylation; (69, 75.8% of the dMMR cases; 20.2% of total). Among the 22 (6.5%) cases with dMMR not explained by methylation, 10 (2.9% of total) were found to have Lynch syndrome (6 MSH6, 3 MSH2, 1 PMS2). Double somatic MMR PV accounted for the remaining 12 dMMR cases (3.5% of total). CONCLUSIONS: Since double somatic MMR gene PV are as common as Lynch syndrome among endometrial cancer patients, paired tumor and germline testing for patients with non-methylated dMMR tumor may be the most efficient approach for LS screening.

Modified model for end-stage liver disease score predicts 30-day mortality in high-risk patients with acute pulmonary embolism admitted to intensive care units.

OBJECTIVES: The Model for End-stage Liver Disease excluding the international normalised ratio that is derived from prothrombin time which is calculated as a ratio of the patient's prothrombin time to a control prothrombin time standardized (MELD-XI) and modified MELD, which uses albumin in place of the international normalised ratio (MELD-Albumin) scores reflect liver and renal function and are predictors of mortality. However, their prognostic value in acute pulmonary embolism (APE) has not been studied. DESIGN: We assessed the predictive value of the MELD scores in patients diagnosed with high-risk APE admitted to the intensive care unit. The primary outcome was 30-day mortality. RESULTS: Of the 273 patients included in the study, 231 were survivors and 42 were non-survivors. The mortality rate was 15.3%. The mean MELD-XI and MELD-Albumin scores were significantly higher in the non-survivors than in the survivors (MELD XI, 11.8 ± 1.8 and 10.6 ± 1.43, respectively; p = .002; MELD-Albumin, 10.5 ± 1.6 and 8.7 ± 1.1, respectively; p = .001). The multiple logistic regression analysis identified the MELD-XI (hazard ratio: 3.029, confidence interval: 1.06-1.21, p = .007) and MELD-Albumin (hazard ratio: 1.13, confidence interval: 1.06-1.21, p = .002) scores as independent predictors of mortality. Receiver operating characteristic analysis revealed that the predictive power of the MELD-Albumin score (0.871 ± 0.014; p < .001) was higher than those of the MELD-XI (0.726 ± 0.022, p < .001), APACHE III (0.682 ± 0.024, p < .001), and PESI (0.624 ± 0.023, p < .001) scores. CONCLUSIONS: The MELD-Albumin score is an easily calculable, reliable, and practical risk assessment tool and independent predictor of 30-day mortality in patients with high-risk APE.

Left atrial volume index and pulmonary arterial pressure predicted MACE among patients with STEMI during 8-year follow-up: experience from a tertiary center.

BACKGROUND: It is important to identify patients that are at high risk following primary percutaneous coronary intervention (P-PCI) for the treatment of ST-segment elevation myocardial infarction (STEMI). Left ventricular ejection fraction (LVEF) is the most important parameter obtained from transthoracic echocardiography (TTE) for risk stratification. The authors evaluated the value of pulmonary artery pressure (PAP) and left atrial volume index (LAVI) for the prediction of major adverse cardiovascular events (MACE) in patients with STEMI that underwent P­PCI. METHODS: A total of 92 patients that underwent P­PCI for STEMI were included in the study. All patients underwent TTE examination before discharge. The composite primary outcome of the study was all-cause mortality and new onset heart failure (HF) during an 8-year follow-up period. RESULTS: The mean age of patients was 61.6 ± 12.4 years and 15 were female (16.3%). Major adverse cardiovascular events (MACE) defined as all-cause mortality and new onset HF occurred in 30 (41%) patients during a mean of 6 ± 2.7 years of follow-up. In the backward multivariate Cox regression analysis LVEF (odds ratio [OR] = 0.933, 95% confidence interval [CI]: 0.876-0.994, p = 0.031), LAVI (OR = 1.069, 95%CI: 1.017-1.124, p = 0.009), PAP (OR = 1.137, 95% CI: 1.057-1.223, p = 0.001) and creatinine level (OR = 1.730, 95% CI: 1.350-1.223, p = 0.029) were found to independently predict MACE during long-term follow-up. Receiver operating characteristic (ROC) curve analysis was performed, revealing that sPAP >24.5 mm Hg had a sensitivity and specificity of 72 and 66%, respectively; LAVI >31 ml/m2 had a sensitivity and specificity of 72.2 and 83.3%, respectively. CONCLUSION: In patients that underwent P­PCI for the treatment for STEMI, LVEF, LAVI, PAP and creatinine level independently predicted all-cause mortality and new onset HF during long-term follow-up.

Systemic immune-inflammation index is associated with increased carotid intima-media thickness in hypertensive patients.

BACKGROUND: Arterial hypertension causes cardiovascular adverse events mainly through endothelial dysfunction, atherosclerosis, and inflammation. Carotid intima-media thickness (CIMT) is a marker of subclinical atherosclerosis and endothelial dysfunction. Systemic immune-inflammation index (SII) reflects systemic inflammatory and immunity status. This index has strong prognostic value in malignancy and recently was demonstrated to be associated with adverse events in cardiovascular diseases. We aimed to interrogate the relationship between SII and CIMT in patients with hypertension. METHODS: A total of 215 consecutive hypertensive patients were included in the study. CIMT of all patients was obtained by B-mode arterial doppler ultrasound. SII was obtained by the following formula: (platelet × neutrophil/lymphocyte ratio) from admission complete blood count. Patients were divided into two groups by means of CIMT is above or below the value of 0.9 mm. SII and demographic characteristics of patients were compared between groups. RESULTS: Increased CIMT was detected in 55 (25.6%) of hypertensive patients. The patients with increased CIMT were older and had higher neutrophil count (p < .001), neutrophil to lymphocyte ratio (NLR) (p < .001), C-reactive protein (CRP) (p = .047), CRP to albumin ratio (CAR) (p = .044) and SII (p < .001) Advanced age (OR: 1.054; 95% CI: 1.015-1.095; p = .006), NLR (OR: 3.213; 95% CI: 1.577-6.546; p = .001), and SII (OR: 3.906; 95% CI: 1.887-8.086; p < .001) were independent predictors of increased CIMT in multivariable logistic regression analysis. CONCLUSION: SII was an independent predictor of elevated CIMT in hypertensive patients. Preventive approaches for future atherosclerotic cardiovascular diseases can be developed in those with higher SII level.

Prognostic nutritional index is related to myocardial performance index in newly diagnosed nondiabetic hypertensive patients.

Background: Arterial hypertension (AH) leads to systolic and/or diastolic dysfunction of the left ventricle (LV) by causing structural changes in the myocardium. Myocardial performance index (MPI) provides the evaluation of LV systolic and diastolic functions together. Prognostic nutritional index (PNI) is an indicator of immunonutritional status. PNI was studied in patients with malignancy, malnutrition, and cardiovascular diseases so far. It was aimed to investigate the relationship between PNI and MPI in hypertensive patients.Methods: A total of 91 consecutive patients with newly diagnosed AH were included in the study. PNI was calculated according to the following formula: ((10 × serum albumin (g/dL))+(0.005 × total lymphocyte count)). MPI was obtained by dividing the sum of isovolumetric relaxation time (IVRT) and isovolumetric contraction time (IVCT) by the ejection time (ET) ((IVRT+IVCT)/ET). Patients were divided into two groups according to MPI is above or below the value of 0.5. The demographic characteristics and PNI values of patients were compared between two groups.Results: There were 65 patients in the higher and 26 patients were in the normal MPI group. Higher MPI group had male predominance (p = .002). Diastolic blood pressure (p = .021), interventricular septum thickness (p = .005), posterior wall thickness (PWT) (p = .001), serum albumin concentration (p = .045), and PNI (p = .013) were differed between groups. Multivariate logistic regression analysis revealed that PWT [OR = 1.835, 95% CI: 1.126-2.992, p = .015] and PNI [OR = 1.161, 95% CI: 1.004-1.343, p = .018] predicted higher MPI.Conclusion: Higher PNI was an independent predictor of LV dysfunction in newly diagnosed hypertensive patients. Immunonutritional status may be used as an indicator of the left ventricular function in patients with AH.

Epicardial adipose tissue predicted prolonged QTc interval in patients with arterial hypertension.

Introduction: It is important to identify those at higher risk for ventricular arrhythmia among hypertensive patients. Epicardial adipose tissue (EAT) leads to electromechanical changes in the heart by endocrine and paracrine effects with cytokines and mediators. Higher amount of EAT carries the risk of QT prolongation. Therefore, we investigated the association between EAT thickness and QTc interval in patients with arterial hypertension. Methods: A total of 230 patients who previously diagnosed with arterial hypertension between February 2019 to March 2020 were included in the study. Patients with atrial fibrillation, U-wave, atrioventricular block, left anterior or posterior fascicular block, right bundle branch block, left bundle branch block, and taking QT-prolonging medication were excluded. The corrected QT (QTc) interval was calculated with Bazzet's formula following the calculated QT interval in the semi-automatic application tool. EAT was measured at the point on the free wall of the right ventricle using transthoracic echocardiography. Results: The mean age was 62.1 ± 11.4 years and 95 (41.3%) of the patients were male. QTc was over 450 ms were considered as the prolonged interval. Both groups were similar in terms of age (p = .862), gender (p = .265) and other demographic characteristics. Left ventricle mass index (LVMI) (82.5 ± 29.5 vs 91.9 ± 32.6 g/1.7.m2, p = .051) and EAT thickness (5.3 ± 2.3 vs 6.6 ± 2.6 mm, p = .001) were higher in the prolonged QTc group. Serum potassium (K) level was lesser in the prolonged QTc group (4.2 ± 0.39 vs 4.1 ± 0.4 mmol/mL, p = .005). Multivariate Cox regression analysis revealed that EAT thickness [OR = 1.227, 95% CI: 1.081-1.393, p = .002] and serum K level [OR = 0.348, 95% CI: 0.157-0.772, p = .009] predicted the prolonged QTc interval, independently. Conclusion: EAT thickness predicted prolonged QTc interval in patients with arterial hypertension. Patients with higher amount of EAT should be followed by closely monitoring to prevent arrhythmic events that may develop in the future. In addition, medications that have a potential effect on QTc interval prolongation may be carefully used in patients with higher EAT thickness.

Assessment of arterial stiffness and epicardial adipose tissue thickness in predicting the subclinical atherosclerosis in patients with ankylosing spondylitis.

OBJECTIVE: Atherosclerosis is a chronic, progressive, inflammatory disease. Recognition of subclinical atherosclerotic vascular changes before clinical manifestation in an asymptomatic population is important for risk stratification and optimal management, which finally leads to the prevention of cardiovascular disease. We aimed to determine the risk of premature subclinical atherosclerosis by evaluating epicardial adipose tissue thickness (EATT) and arterial stiffness parameters in patients with ankylosing spondylitis (AS). METHODS: We performed a prospective study of 60 consecutive patients meeting modified New York criteria for AS compared to 60 controls matched for age and sex. Patients with traditional cardiovascular risk factors were excluded. Arterial stiffness parameters and EATT (examined via echocardiography) values of all patients and control groups were measured. RESULTS: There was no difference between basal characteristic and echocardiographic parameters in patients with AS and in the control group. EATT and pulse wave velocity (PWV) were higher in the AS patients compared to the control group. EATT was 5.74 ± 1.22 mm and 4.91 ± 1.21 mm (p < .001) and PWV was 9.90 ± 0.98 m/s and 6.46 ± 0.83 m/s (p = .009) in the AS and control groups, respectively. Also, PWV was significantly correlated with EATT, age, and central blood pressure in patients with AS. CONCLUSIONS: EATT and PWV, markers of atherosclerosis and cardiovascular disease, were significantly higher in patients with AS than the control group. In addition, in this study, it has been shown that there is a significant relationship between PWV and EATT in patients with AS.

Assessment of fragmented QRS formation and its relationship with left ventricular hypertrophy in nonhypertensive acromegaly patients

Background/aim: It is known that the presence of fragmented QRS (fQRS) on electrocardiography (ECG) is associated with cardiovascular events. The aim of this study was the evaluation of fQRS formation and its relationship with the left ventricular hypertrophy (LVH) parameters in acromegaly patients. Materials and methods: In total, 47 previously diagnosed with non-hypertensive acromegaly patients and 48 control subjects were included in the study. ECG and transthoracic echocardiography (TTE) were performed for each participant. Acromegaly patients were divided into two groups according to the fQRS formation on the ECG. Left ventricular wall thicknesses, and left atrial diameter (LAD), left ventricular mass (LVM), left ventricular mass index (LVMi), and relative wall thickness (RWT) were obtained. Results: In control group 5 (10.4%) and in acromegaly group 17 (36.2%) patients had fQRS on ECG (p = 0.003). LAD [36.0 (34.0­38.0) vs. 38.0 (35.0­41.0) mm, p < 0.001], LVM [155.27 ± 27.00 vs. 173.0 (153.0­235.0) g, p < 0.001], LVMi [83.12 ± 13.19 vs. 92.0 (83.0­118.0) g/m², p < 0.001] and RWT [0.39 ± 0.03 vs. 0.43 (0.41­0.45), p = 0.001] were significantly higher in patients with acromegaly. Disease duration was significantly higher (11.59 ± 1.3 vs. 8.2 ± 1.8 years, p < 0.001) in the fQRS (+) group. LAD [41.0 (39.0­42.5) vs. 37.0 (34.7­38.0) mm, p < 0.001], LVM [219.0 (160.5­254.5) vs. 164.0 (153.0­188.0) g, p = 0.017], LVMi [117.0 (92.5­128.5) vs. 86.0 (82.0­100.2) g/m², p = 0.013] and RWT [0.44 (0.42­0.49) vs. 0.43 (0.40­0.44), p = 0.037] were significantly higher in fQSR (+) acromegaly patients. In multivariate logistic regression analysis, disease duration (odds ratio: 10.05, 95% CI: 1.099­92.012, p = 0.041) and LAD (odds ratio: 2.19, 95% CI: 1.030­4.660, p = 0.042) were found to be the independent predictors of fQRS formation. Conclusion: The results of our study revealed that fQRS (+) acromegaly patients had increased LVH parameters compared to fQRS (-) patients.

The association of exaggerated hypertensive response to exercise and beta-blockers use in hypertensives.

PURPOSE: An elevation in blood pressure (BP) during exercise is the normal physiological response, however an abnormally exaggerated rise in BP, in terms of hypertensive response to exercise (HRE), is seen as a prognostic factor for end-organ damage and mortality. HRE is more common in hypertensive (HT) patients and data are lacking on the effect of antihypertensive medication on HRE. In this study, we evaluated patients who underwent treadmill exercise testing (TET) to reveal the effect of antihypertensive medication on HRE. MATERIALS AND METHODS: A cohort of 2970 individuals underwent TET and data were evaluated for HRE development. HRE has been defined as a systolic BP>210 mmHg in males and >190 mmHg in females throughout the TET. To reveal the effects of antihypertensive medication on HRE, 992 HT patients were analyzed. RESULTS: HRE was observed in 11.4% (n = 113) of HT patients and 5.9% (n = 107) of non-HT individuals(p < .001). HRE was observed significantly more in males (57.6% vs. 67.3%;p = .033), and in patients with higher body mass index BMI (29.1 ± 4.5 vs. 30.3 ± 5.2;0.033). There was no significant association between medication and HRE development apart from beta-blockers. Also, gender (odds ratio:1.787; 95%CI:1.160-2.751;p = .008), BMI (odds ratio:1.070;95%CI:1.025-1.116;p = .002) and being under beta-blocker treatment (odds ratio:0.637;95%CI:0.428-0.949;p = .026) were found to be independent predictors of HRE in multivariate logistic regression analysis. CONCLUSION: HRE was associated with gender, BMI and beta-blocker use in hypertensive with male gender and higher BMI associated with higher HRE, while beta-blocker-based treatment, either mono- or combination therapy, associated with lower HRE.

Increased epicardial fat tissue thickness predicts advanced interatrial block among hypertensive patients.

BACKGROUND: Recent studies demonstrated that epicardial fat tissue (EFT) was associated with prevalent AF and recurrences following the catheter ablation. We evaluated the value of EFT for the prediction of advanced interatrial block (a-IAB) in the surface electrocardiography (ECG) among hypertensive patients. METHODS: Patients with prior diagnosis of hypertension (HT) were included in the study. Surface ECG and transthoracic echocardiography (TTE) were performed to each patient. A-IAB was defined as P-wave duration longer than 120 ms with biphasic morphology in the inferior leads. EFT was identified by using TTE and was measured perpendicularly in front of the right ventricular free wall at the end-systole. RESULTS: Between February 2019 and February 2020 245 patients met the eligibility criteria. A-IAB was found among 35 patients and compared to those without IAB, they had increased waist circumference, elevated left ventricular mass index (LVMI) and left atrial volume index (LAVI), lower LDL and increased P wave duration. EFT thickness was higher in patients with a-IAB compared to those without (5.3 ±â€¯2.2 mm vs 7.6 ±â€¯2.4 mm). Multivariable analysis revealed that increased EFT thickness and lower LDL level predicted a-IAB. CONCLUSION: Among patients with prior diagnosis of HT, higher EFT thickness evaluated by TTE predicted the presence of a-IAB on the surface ECG.

Presystolic wave is associated with carotid intima media thickness.

INTRODUCTION: Carotid intima media thickness (CIMT), a direct marker of atherosclerosis, has emerged as a promising means for cardiovascular risk evaluation. Presystolic wave (PSW) is commonly detected by the Doppler interrogation of the left ventricular outflow tract (LVOT). It is thought to be a result of a stiff left ventricle and impaired LV compliance. Herein, we aimed to investigate a possible association between carotid intima media thickness, an atherosclerotic marker, and PSW. METHOD: We prospectively enrolled 282 patients divided into two groups based on the presence of PSW: 221 (89F; mean age: 49.3 ± 11.5 years) had PSW on Doppler examination while 61 patients (32F; mean age: 46.4 ± 10.3 years) did not. Both groups were compared with respect to demographic, clinical properties, and CIMT. RESULTS: Both groups had comparable age, body mass index, and diabetes mellitus, hypertension, dyslipidemia, smoking, and family history for coronary heart disease. PSW-positive group had significantly higher CIMT (PSW-positive: 0.59 ± 0.22 mm vs PSW-negative: 0.42 ± 0.11 mm; P < 0.001) than PSW-negative group. Multivariate analysis showed that the independent predictors of increased CIMT were age (95% CI; 1.044-1.101, P < 0.001), dyslipidemia (95% CI; 0.147-0.664, P = 0.002), and the presence of PSW (95% CI; 2.168-7.836, P < 0.001).Correlation analysis showed that PSW velocity is correlated with increased CIMT in PSW-positive group (r: 0.418, P < 0.001). CONCLUSION: Assessment of PSW on TTE is easy and feasible method. Presence of PSW and increased PSW velocity on TTE might provide information that we should be careful in terms of subclinical atherosclerosis.

Predictors of new-onset atrial fibrillation in elderly patients with acute coronary syndrome undergoing percutaneous coronary intervention.

BACKGROUND: The development of atrial fibrillation (AF) during the course of acute coronary syndrome (ACS) is related to poor prognosis. Possible predictors of new-onset AF (NOAF) have not been adequately investigated in elderly patients with ACS undergoing percutaneous coronary intervention (PCI). We aimed to identify the factors associated with NOAF in such patients. METHODS: A total of 308 elderly patients with ACS undergoing PCI were enrolled in the study. Patients were divided into two groups: without NOAF [254 patients, 64.6% men, age: 73.5 (69.0-79.0) years] and with NOAF [54 patients, 70.4% men, age: 75.0 (68.7-81.2) years]. Clinical, angiographic, and laboratory features including neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-high-density lipoprotein ratio (MHR) were compared between the groups. RESULTS: The percentages of prior myocardial infarction (MI) (20.4 vs. 5.9%) and Killip III/ IV (24.1 vs. 7.1%), NLR [4.5 (2.6-7.2) vs. 3.2 (2.0-6.0)], and MHR [19.4 (15.7-26.5) vs. 12.9 (9.9-18.5)] were higher in patients with NOAF compared to the others (p = 0.020, < 0.001, 0.030, and < 0.001, respectively). In multivariate regression analysis, prior MI (OR 4.509, 95% CI 1.679-12.106, p = 0.003) and MHR (OR 1.102, 95% CI 1.054-1.152, p < 0.001) independently predicted NOAF. In addition, Killip III/IV was found to be an independent predictor of 6-month overall mortality (HR 2.949, 95% CI 1.218-7.136, p = 0.016). CONCLUSIONS: Prior MI and MHR are independent predictors of NOAF in elderly patients with ACS undergoing PCI. Killip III/IV predicts 6-month overall mortality in such patients.
