RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIM: Preeclampsia is one of the major causes of perinatal, fetal, and maternal mortality and morbidity. The aim of this study was to investigate the association of serum interleukin 37 (IL 37) with preeclampsia. METHODS: 39 women with preeclampsia were included as the study group. 38 healthy, and normotensive pregnant women, at similar gestational week with similar gravidity volunteered as the control group. Clinical findings, biochemical parameters, maternal and perinatal outcomes, and the serum concentrations of IL37 were compared between the groups. The relationship of IL 37 concentrations with clinical findings and blood pressure outcomes were also investigated. RESULTS: Maternal serum IL 37 concentrations were significantly higher in patients with preeclampsia compared to the healthy pregnant women in the control group (p = .005). IL 37 positively correlated systolic blood pressure (BP) (r = 0.344, p = .002), and diastolic BP (r = 0.332, p = .003). IL 37 was identified as an independent predictor of preeclampsia. CONCLUSIONS: Serum IL 37 concentrations were higher in preeclamptic patients compared to healthy pregnant women. Furthermore, IL 37 concentrations achieved success in identifying preeclampsia with hypertension. Increased IL 37 activity may have a role in the pathophysiology of preeclampsia.

RESUMEN

Background: Arterial hypertension is one of the leading causes of mortality and morbidity in general population. Sirtuin 1 (SIRT1) has diverse anti-inflammation, anti-oxidant, and anti-apopytosis effects on endothelium and is associated with endothelial aging and dysfunction. The objective of this study was to evaluate the relation of serum SIRT1 level with left ventricular hypertrophy (LVH) in newly diagnosed hypertensive patients. Methods: One hundered and twenty-five consecutive, newly diagnosed hypertensive patients were divided into two groups with regard to presence of LVH and compared to 40 healthy control subjects. LVH was determined by transthoracic echocardiography using the cube formula. Serum SIRT1 level was analyzed with enzyme-linked immunosorbent assay. Results: Serum SIRT1 level was significantly higher in patients with LVH compared to those without LVH (14.3 ± 3.9 ng/ml vs. 7.9 ± 3.6 ng/ml, ​P < 0.001) and healthy control subjects (14.3 ± 3.9 ng/ml vs 6.6 ± 2.0 ng/ml, P < 0.001). Multivariate logistic regression analysis revealed higher serum SIRT1 level independently predicted LVH in hypertensive patients (OR 1.50; 95% CI, 1.30-1.73; P < 0.001). Receiver-operating characteristic curve analysis demonstrated a cutoff value of 9.4 had a sensitivity of 90% and specificity of 74% for the prediction of LVH (AUC 0.885; 95% CI, 0.815-0.935; ​P < 0.0001). Conclusion: SIRT1 was a powerful biomarker for predicting LVH in hypertensive patients.

RESUMEN

Background: Visceral obesity is strongly associated with atherosclerosis. Even though waist circumference (WC) is the most common assessment method of total visceral adipose tissue and cardiometabolic risk, this method lacks direct measurement of adipose tissue and has better correlation to subcutaneous fat rather than visceral fat. We intended to investigate whether epicardial adipose tissue (EAT) is clinically superior to body mass index (BMI) and WC in predicting Framingham risk score (FRS) and carotid intima-media thickness (CIMT). Methods: Our study included 331 patients who were admitted to our outpatient clinic for risk factor assessment. We calculated BMI, FRS, and WC, and the patients underwent echocardiographic and carotid examinations to measure EAT and CIMT. The metabolic syndrome (MS) score was calculated by summing the MS risk factor scores. Results: The area under the curve values of EAT were similar to FRS and higher than those of weight, BMI, and WC for both increased CIMT and the presence of carotid plaque. Male gender, age, low-density lipoprotein-cholesterol level, and EAT thickness were independent predictors of CIMT, whereas male gender, age, WC, uric acid concentration, and EAT significantly predicted the presence of carotid plaque. Conclusions: This study demonstrated that epicardial adipose tissue (EAT) has a stronger correlation with CIMT than BMI and WC, and it was a significant predictor of increased CIMT and the presence of carotid plaque. Additional data are required to clarify the diagnostic and therapeutic role of EAT in managing obese patients, and to decrease their cardiometabolic risk.

RESUMEN

OBJECTIVE: To investigate the association of epicardial adipose tissue thickness with irritable bowel syndrome. METHODS: This case-control and observational study was conducted in Recep Tayyip Erdogan University between January and December 2014, and comprised patients of irritable bowel syndrome and healthy controls who underwent a complete transthoracic echocardiographic examination as well as measurements of epicardial adipose tissue. They were screened for psychiatric or organic bowel diseases for the sake of precise diagnosis. Epicardial fat thickness was measured perpendicularly in front of the right ventricular free wall at end-diastole.SPSS 15 was used to analyse the data. RESULTS: Of the 75 subjects, 44(59%) were patients and 31(41%) were controls. There was no statistically significant difference between the groups except epicardial adipose tissue thickness, which was significantly elevated in patients (p<0.001). C-reactive protein was significantly higher in patients (p=0.002). Epicardial adipose tissue (p<0.001) and haematocrit (p<0.05) were independent predictors of irritable bowel syndrome. CONCLUSIONS: Increased epicardial adipose tissue thickness, and accompanying low-grade inflammation appeared to be involved in irritable bowel syndrome pathogenesis.

RESUMEN

Background: Apelin, an endogenous peptide, has recently gained attention due to its positive inotropic effects in heart failure physiopathology. We investigated the relationship between serum apelin levels and the severity of calcific aortic stenosis (AS). Methods: A total of 68 consecutive patients diagnosed with calcific AS and a control group of 32 subjects were included in the study. The subjects were divided into three group as follows: the control group, the mild-moderate AS group and the severe AS group. Blood samples were obtained from all of the subjects, which were used for biochemical comparisons of apelin 36 and high-sensitive C-reactive protein (hsCRP) levels. Results: Plasma apelin 36 levels were significantly lower in the patients with severe AS [490 (247-1074) pg/ml] compared to both the mild-moderate AS [209 (97-453) pg/ml] and control [660 (378-1200) pg/ml] groups (p < 0.001). Correlation analysis between the left ventricular mass index and apelin concentrations revealed a significant negative correlation between the two parameters (p < 0.001, r = -0.478). Conclusions: Our study demonstrated decreased apelin levels and increased hsCRP concentrations in patients with severe calcific AS. Our findings may help to clarify the exact pathophysiologic role of apelin in cardiovascular diseases.

RESUMEN

BACKGROUND We planned to investigate the relationship of thrombus burden with SYNTAX score in patients with ST elevation myocardial infarction (STEMI). MATERIAL AND METHODS We retrospectively enrolled 780 patients who underwent PPCI in our clinic due to STEMI. Clinical, laboratory, and demographic properties of the patients were recorded. Angiographic coronary thrombus burden was classified using thrombolysis in myocardial infarction (TIMI) thrombus grades. RESULTS Patients with high thrombus burden were older, with higher diabetes prevalence longer pain to balloon time, higher leukocyte count, higher admission troponin, and admission CK-MB concentrations. SYNTAX score was higher and myocardial perfusion grades were lower in patients with high thrombus burden. Multivariate logistic regression analysis revealed SYNTAX score as the strongest predictor of thrombus burden. ROC analysis demonstrated a sensitivity of 75.5%, specificity of 61.2%, and cut-off value of >14 (area under the curve (AUC): 0.702; 95% confidence interval [CI]: 0.773-0.874;P<0.001) for high thrombus burden. CONCLUSIONS SYNTAX score may have additional value in predicting higher thrombus burden besides being a marker of coronary artery disease severity and complexity.

RESUMEN

AIM: The aim of this study was to evaluate the effects of percutaneous mitral balloon valvuloplasty (PMBV) on short- and intermediate-term aortic stiffness in patients with mitral stenosis. MATERIALS AND METHODS: This prospective study included 56 patients with critical mitral stenosis in normal sinus rhythm (68% female; mean age: 42 ± 11 years) and 37 healthy controls. Aortic stiffness was measured using transthoracic echocardiography before PMBV, and 24-48 hours and 1 year post procedure. RESULTS: Aortic strain and distensibility were significantly higher in the patients with mitral stenosis, both after PMBV and 1 year post procedure, whereas the aortic stiffness index (ASI) was significantly lower. There was also a significant decrease in mitral mean gradient (MMG) and systolic pulmonary artery pressure (sPAP) after PMBV, based on echocardiography and catheterization. Mitral valve area (MVA) significantly increased after PMBV. There was a significant correlation between change in ∆MVA and ∆MMG and aortic elastic properties. There was a significantly negative correlation between the ∆MVA and ∆∆ aortic stiffness (r = -0.62, P < 0.001), and a significantly positive correlation between ∆MMG and ∆ASI (r = 0.60, P < 0.001). CONCLUSION: Mitral valve stenosis was associated with impaired aortic stiffness and following PMBV, aortic stiffness decreased during both the acute period and the intermediate period.

RESUMEN

AIMS: Currently, it remains unclear whether there are differences in the long-term physiologic and adaptive changes in an athlete's heart, varying by the type of exercise undertaken. In this study, we used standard and speckle tracking echocardiography (STE) to evaluate the long-term effects of cardiac remodeling, which persisted many years after retiring from professional sports (marathon running and wrestling). METHODS AND RESULTS: Twenty-four marathon runners, 25 wrestlers, and 24 healthy subjects were included in the study. Left ventricular (LV) strain (S) and strain rate (Sr) were evaluated by apical two- (2C), three- (3C), and four-chamber (4C) imaging. Global S and Sr were calculated by averaging the 3 apical views. The participants' mean age was comparable across the 3 groups. Weight, body mass index, LV mass, LV mass index, and relative diastolic wall thickness were higher in wrestlers than the other groups (P < 0.001). Systolic and diastolic functions, evaluated using conventional echocardiography, were comparable among the 3 groups. 2C, 3C, and 4C longitudinal strain (LS), global LS (GLS), and global Sr systolic filling (SrS) values were comparable between the marathon runners and control group; however, GLS, LS-2C, GLSrS, SrS-3C, and SrS-2C values were significantly increased in wrestlers compared with the control group. CONCLUSIONS: Myocardial changes in wrestlers and marathon runners who quit sports after an extensive period were evaluated using standard echocardiographic and STE parameters. Although they had stopped playing active sports more than 10 years earlier, both the structural and functional properties of the heart were maintained in wrestlers.

RESUMEN

OBJECTIVE: High-density lipoprotein cholesterol (HDL-C) levels are inversely related to the risk of coronary artery disease (CAD). Alterations in HDL-C subclass distribution and HDL-associated enzyme activities may be more important than total HDL levels for the progression of CAD. We intended to investigate the relationship of HDL-C subclass distribution and HDL-associated enzyme activities with CAD. METHOD AND RESULTS: Our study included 101 patients with stable coronary artery disease, and 64 healthy subjects. Serum levels of HDL lipoprotein-associated-phospholipase A2 (HDL-LpPLA2), paraoxonase 1 (PON1), and HDL subfraction distribution were measured. We found increased small HDL (sHDL) subfractions in patients with one-vessel disease (P < 0.001). We also found a reverse correlation between total HDL-C levels and affected vessel number (P < 0.05). Plasma HDL-Lp PLA2 enzyme level was higher in each vessel disease category compared to the control group (P < 0.001). However, PON1 enzyme activity in patients with CAD was not statically significant. Plasma sHDL, HDL-Lp PLA2 enzyme and Lp(a) were significantly different between subjects with CAD and control participants. CONCLUSIONS: We demonstrated decreased sHDL particles and a lower cardioprotective HDL-LpPLA, enzyme activity in all patient subgroups compared to controls. Measurement of total HDL-C level only may not be sufficient to predict CAD risk.

RESUMEN

OBJECTIVE: Epicardial adipose tissue (EAT) secretes various pro-inflammatory and atherogenic mediators that have several endocrine and paracrine effects on heart. This study investigated the influence of EAT on QT and P wave dispersions (QTd, PWd), as simple, non-invasive tools of proarrhythmia on surface ECG. METHODS: This was a cross-sectional study and included 70 patients with normal coronary arteries who underwent 12-derivation electrocardiography, echocardiography and biochemical examinations in order for QTd, PWd, and EAT thickness to be measured. RESULTS: Median EAT thickness was 4.1 mm. Correlation analyses revealed that EAT was significantly associated with age (r=0.412, p<0.001), weight (r=0.262, p=0.028), body mass index (r=0.396, p<0.001), left atrium diameter (r=0.518, p<0.001), fasting plasma glucose (r=0.245, p=0.041), maximum P wave duration (r=0.343, p=0.004), minimum P wave duration (r=0.275, p=0.021) and PWd (r=0.265, p=0.026). No relation was found between study parameters and QTd. However, P wave dispersion was significantly related to EAT thickness (r=0.265, p=0.026), left atrium diameter (r=0.483, p<0.001), and the triglyceride levels (r=0.267, p=0.028). Multiple linear regression analyses revealed left atrial diameter as the only independent predictor of PWd. CONCLUSION: A significant association between EAT and PWd was demonstrated in the study. While EAT is related to both increased PWd and left atrial size, left atrial diameter seems to be more important than EAT for prediction of atrial fibrillation (AF) in patients with normal coronary arteries.

RESUMEN

BACKGROUND: In patients presenting with non-ST elevation myocardial infarction, we investigated the relationship of left atrial deformational parameters evaluated by 2-dimensional speckle tracking imaging (2D-STI) with conventional echocardiographic diastolic dysfunction parameters and brain natriuretic peptide level. MATERIAL AND METHODS: We enrolled 74 non-ST segment elevation myocardial infarction patients who were treated with percutaneous coronary intervention and 58 healthy control subjects. Non-ST segment elevation myocardial infarction patients had echocardiographic examination 48 h after the percutaneous coronary intervention procedure and venous blood samples were drawn simultaneously. In addition to conventional echocardiographic parameters, left atrial strain curves were obtained for each patient. Average peak left atrial strain values during left ventricular systole were measured. RESULTS: BNP values were higher in non-ST segment elevation myocardial infarction patients compared to controls. Mean left atrium peak systolic global longitudinal strain in Group 2 (the control group) was higher than in the non-ST segment elevation myocardial infarction group. Left atrium peak systolic global longitudinal strain was significantly correlated with left ventricular ejection fraction. There was a significant inverse correlation between left atrium peak systolic global longitudinal strain and brain natriuretic peptide level, left atrium volume maximum, and left atrium volume minimum. CONCLUSIONS: Our study shows that Left atrium peak systolic global longitudinal strain values decreased consistently with deteriorating systolic and diastolic function in non-ST segment elevation myocardial infarction patients treated with percutaneous coronary intervention. Left atrium peak systolic global longitudinal strain measurements may be helpful as a complimentary method to evaluate diastolic function in this patient population.

RESUMEN

BACKGROUND: We aimed to examine the correlation among nighttime blood pressure, heart rate variability, and left atrium peak systolic global longitudinal strain among patients with subjective tinnitus. MATERIAL AND METHODS: Eighty patients with tinnitus were assigned to Group 1 and 80 healthy individuals were assigned to Group 2. Clinical blood pressure measurements, ambulatory blood pressure monitoring, and Holter electrocardiography monitoring were performed. All of the cases included in the study were examined with conventional echocardiography and 2-dimensional speckle tracking echocardiography. RESULTS: Mean nighttime systolic blood pressure (130.3±5.4) and mean nighttime diastolic blood pressure (82.8±3.9) in Group 1 were higher than in Group 2 (125.1±5.4 and 80.7±4.7, respectively) (p<0.05). Mean heart rate in Group 1 was significantly lower than in Group 2 but there was no statistically significant difference between the groups in terms of heart rate variability parameters and left atrium peak systolic global longitudinal strain values (p>0.05). CONCLUSIONS: Nighttime systolic blood pressure and nighttime diastolic blood pressure were higher among the patients with tinnitus. In light of these results, we can conclude that both clinical blood pressure measurement and ambulatory blood pressure monitoring are important for patients with tinnitus.

RESUMEN

Esophageal perforation is a serious condition with a high mortality rate. Delayed detection of esophageal perforation may result in devastating complications such as mediastinitis and pericarditis. Esophageal perforation is rarely due to aspiration of foreign bodies. Here we report the case of a 59-year-old male patient with complicated esophageal perforation due to ingestion of a chicken bone, whose first signs are considered to be acute non-specific pericarditis.

RESUMEN

BACKGROUND: Anxiety and depression can adversely affect the prognosis following cardiovascular diseases (CVDs) and may be associated with resistance to hypertension (HT) treatment. A better understanding of the complex biological substratum of resistant HT complicated by depression and anxiety is crucial for designing future primary care strategies. OBJECTIVES: To evaluate the relationship between anxiety and depression and resistant HT, which will help to look at resistant HT from a broader perspective and aid the development of new strategies for diagnosis and treatment. MATERIAL AND METHODS: We used a stratified random sampling method to select HT patients aged 18 and older in primary care setting. A total of 300 consecutive patients with persistent HT who were diagnosed with essential HT and uncontrolled blood pressure (BP) despite antihypertensive therapy were prospectively included in the study. Anxiety and depression were investigated, and scoring was evaluated using the Hospital Anxiety and Depression Scale (HADS). RESULTS: The study included 108 controlled and 91 uncontrolled HT patients. The HADS scales were higher in the controlled HT group compared to the uncontrolled HT group (6 (0-18) compared to 9 (0-20), p = 0.001; 5 (0-17) compared to 7 (0-16), p < 0.001, respectively). Body mass index (BMI) and C-reactive protein (CRP) were also significantly higher in the uncontrolled HT patients compared to the normotensive group. Anxiety was associated with a 2.18 times increased risk of HT and a 1.99 times increased risk of depression. Thus, anxiety and depression predicted resistant HT in both univariate and multivariate analyses. CONCLUSIONS: During the treatment of HT, efforts should be made to improve the psychological and social functions of the patients beyond the primary therapy for control of the disease. As such, we hope to draw attention to the importance of psychological factors, especially anxiety and depression, in any field of medicine related to managing resistant HT.

RESUMEN

High-grade intracoronary thrombus (ICT) burden leads to greater myocardial injury following anterior myocardial infarction (MI). The modified Glasgow prohgnostic score (mGPS) is a novel immune-inflammatory index, calculated by using C-reactive protein (CRP) and albumin levels, was shown to have prognostic value in heart diseases. The present study investigated the role of mGPS in predicting high grade ICT in patients with acute anterior MI admitted between February 2017 and March 2020. Blood samples were obtained at admission and mGPS was calculated. The ICT burden was evaluated visually from angiographic images. Patients were divided into 2 groups according to the ICT burden as high and low. A total of 1132 patients were enrolled: a mean age 61 ± 12.4 years and 370 males (32.7%). Serum albumin was lower, whereas mGPS and CRP were higher in high grade ICT group. CRP (odds ratio (OR): 1.404 95% CI: 1.312-1.502; P < .001), albumin (OR: .486; 95% CI: .301-.782 P < .001), and mGPS (0 vs ≥ 1) (OR: 7.391; 95% CI: 3.910-13.972; P < .001) were independent predictors of high-grade ICT burden in the left anterior descending coronary artery. The mGPS is a novel predictor of high-grade ICT burden and may be useful for risk stratification in patients with acute anterior MI.
