Introduction Obstructive sleep apnea (OSA) and endothelial dysfunction are associated with cardiovascular risk factors and the development of atherosclerosis. Endocan is a marker of endothelial dysfunction, while obstructive sleep apnea is one of the causes of endothelial dysfunction. In this study, we investigated the relationship between endocan and obstructive sleep apnea severity. Material and methods A total of 179 patients with snoring complaints were included. All patients underwent polysomnography, and based on the results, the participations were allocated to the control group (n = 39) or to the obstructive sleep apnea group (n = 140). The OSA group was classified as having mild (apnea-hypopnea index (AHI) = 5–15; n = 43), moderate (AHI = 15–30; n = 42), or severe OSA (AHI > 30; n = 55). All participations had their endocan levels measured. Results Endocan levels in OSA patients were significantly higher than in the control group (11.8 (3.13–200) vs 3.13 (3.13–23) ng/ml, p < 0.001). Also, endocan levels were significantly higher in the severe OSA group than moderate and mild obstructive OSA (13.2 (3.13–200), 12.6 (3.13–200) and 8.44 (3.13–50.5) ng/ml, p = 0.015, respectively). Multiple logistic regression analysis showed that smoking, age and endocan levels were independent predictors of OSA severity (p = 0.024, p = 0.037, p = 0.004, respectively). Conclusions Endocan seems to be a potential risk stratification marker in this patient population.

Background and Objectives: This study aimed to evaluate the relationship between mortality and cardiac laboratory findings in patients who were hospitalized after a positive PCR for COVID-19 infection. Materials and Methods: This study included patients who were admitted to or referred to the hospital between 20 March and 20 June 2020, diagnosed with COVID-19 via a positive RT-PCR from nasal and pharyngeal swab samples. The troponin I level was measured from each patient. Medical records of patients were retrospectively reviewed and analyzed. Results: A hundred and five patients who were diagnosed with COVID-19 and hospitalized, or who died in the hospital due to COVID-19, were included in this study. There was a statistically significant difference between the troponin I high and low level groups in terms of age (years), BMI, shortness of breath (SB), oxygen saturation (%), hypertension, length of stay in the ICU, and for mortality, C-reactive protein, the neutrophil-to-lymphocyte ratio, hemoglobin, lactate dehydrogenase, ferritin, D-dimer, creatine kinase-MB, prothrombin time, calcium, and 25-hydroxy vitamin 25(OH)D3 (all p &lt, 0.05). In the logistic analyses, a significant association was noted between troponin I and the adjusted risk of mortality. A ROC curve analysis identified troponin I values &gt, 7.8 pg/mL as an effective cut-off point in mortality for patients with COVID-19. A troponin I value of higher than 7.8 pg/mL yielded a sensitivity of 78% and a specificity of 86%. Conclusions: The hospital mortality rate was higher among patients diagnosed with COVID-19 accompanied by troponin levels higher than 7.8 pg/mL. Therefore, in patients diagnosed with COVID-19, elevated troponin I levels &gt, 7.8 pg/mL can be considered an independent risk factor for mortality.

Introduction: Previous studies have demonstrated the predictive value of the neutrophil-to-lymphocyte ratio (NLR) in many cardiovascular disorders. The aim of this study was to assess whether NLR is associated with echocardiographic or electrocardiographic parameters, or with predicted five-year risk of sudden cardiac death (SCD), in patients with hypertrophic cardiomyopathy (HCM). Methods: This prospective observational study included 74 controls and 97 HCM patients. Three years of follow-up results for HCM patients were evaluated. Results: NLR was significantly higher in patients with fragmented QRS, ventricular tachycardia, and presyncope than in those without (p=0.031, 0.030, and 0.020, respectively). NLR was significantly higher in patients whose predicted five-year risk of SCD was more than 6% and whose corrected QT interval was greater than 440 ms (p=0.022 and 0.001, respectively). It was also significantly higher in patients whose left ventricular ejection fraction (LVEF) was 60% (p=0.017). Conclusion: NLR was significantly higher in patients with HCM compared to the control group. A high NLR is associated with a higher five-year risk of SCD in patients with HCM. Resumo: Introdução: Estudos prévios demonstraram o valor preditivo da relação neutrófilos/linfócitos (RNL) em muitas alterações cardiovasculares. O objetivo deste estudo foi avaliar se a RNL está associada a parâmetros ecocardiográficos ou eletrocardiográficos, ou com o score de risco de morte súbita cardíaca (MSC) a cinco anos em doentes com miocardiopatia hipertrófica (MCH). Métodos: Este estudo prospetivo observacional incluiu 74 controlos e 97 doentes com MCH. Foram avaliados os resultados dos doentes com MCH ao longo de três anos de seguimento. Resultados: O valor da RNL foi significativamente superior nos doentes com QRS fragmentado, com taquicardia ventricular e com pré-síncope do que nos que não revelaram esses sinais (valores p: 0,031, 0,030, 0,020, respetivamente). O valor RNL foi estatística e significativamente superior nos doentes com risco de MSC previsível a cinco anos superior a 6%, e com um intervalo QT corrigido superior a 440 ms (valores p: 0,022, 0,001, respetivamente). O valor da RNL foi significativamente superior nos doentes com fração de ejeção (FE) 60% (valor p = 0,017). Conclusão: A RNL foi significativamente superior nos doentes com MCH quando comparada com o grupo controlo. Uma RNL alta está associada a um score de risco de MSC elevado aos cinco anos em doentes com MCH.

Data on D-dimer assay, GRACE and TIMI risk scores were recorded. Logistic regression analysis was conducted to determine the risk factors predicting increased mortality.Results: Median D-dimer levels were 349.5 (48.0–7,210.0) ng/mL, the average TIMI score was 3.2±1.2 and the GRACE score was 90.4±27.6 with high GRACE scores (>118) in 17.5% of patients. The GRACE score was correlated positively with both the D-dimer assay (r=0.215, P=0.01) and TIMI scores (r=0.504, P=0.000). Multivariate logistic regression analysis revealed that higher creatinine levels (odds ratio =18.465, 95% confidence interval: 1.059–322.084, P=0.046) constituted the only significant predictor of increased mortality risk with no predictive values for age, D-dimer assay, ejection fraction, glucose, hemoglobin A1c, sodium, albumin or total cholesterol levels for mortality.Conclusion: Serum creatinine levels constituted the sole independent determinant of mortality risk, with no significant values for D-dimer assay, GRACE or TIMI scores for predicting the risk of mortality in NSTEMI patients.

The objective of this study was to compare the Atherogenic Index of Plasma (AIP) values as indicators of subclinical atherosclerosis among 124 patients with erectile dysfunction, which was thought to be vasculogenic and 126 control subjects who had no erectile dysfunction, and to compare cardiac performance values between both the groups using exercise stress tests (EST). Erectile function was assessed using the International Index of Erectile Function (IIEF-5) questionnaire form. AIP values were studied and compared between patients with ED (IIEF < 22) and those without ED (IIEF > 22) using the log10 TG/HDL-C formula. In addition, the correlation between the severity of ED and AIP was investigated according to IIEF-5 scoring. Metabolic equivalent (MET) values, maximal heart rates (max HR), and heart rate recovery (HRR) were evaluated with effort tests. AIP values were significantly higher in the ED group than in the control group (0.45 ± 0.27, and 0.37 ± 0.27; p = 0.015). According to IIEF-5 scoring, AIP values increased as ED scores decreased. In the EST, MET score and max HR values were significantly lower in the ED group (METs: 11.1 ± 2.2, and 11.6 ± 2.2; p = 0.045; Max HR: 162.8 ± 6.1, and 165 ± 8.7; p = 0.019). Although not statistically significant, HRR values were lower in the ED group. Higher AIP values were found in the ED group, and a positive correlation was established between AIP and the severity of ED. In addition, lower performance during the EST and lower HRR values, again in the ED group, confirms cardiac interaction with ED. These results indicate the importance of referral of patients with ED from urology clinics to cardiology units for risk determination and cardiac assessment, even if they areasymptomatic.

Objective: The aim of this study was to determine the relationship between serum uric acid (UA) level and the predicted risk score for sudden cardiac death in 5 years (the HCM Risk-SCD), galectin-3 level, and positive fragmented QRS (fQRS) on electrocardiography (ECG) in patients with hypertrophic cardiomyopathy (HCM). Methods: This was a prospective, observational study. In all, 115 consecutive patients (age >17 years) with HCM and 80 healthy participants were included in the study. The HCM Risk-SCD score (%), galectin-3 level, and fQRS on ECG were evaluated in all patients. Results: The serum UA, galectin-3 level, UA/Creatinine ratio, incidence of ventricular tachycardia (VT) and syncope, and some echocardiographic parameters were significantly higher in the patient group than in the control group (all p6%. Namely, HCM Risk-SCD >6%, UA: 6.71+-1.29 mg/dL, HCM Risk-SCD ≤5.9%, UA: 5.84+-1.39 mg/dL, p=0.001; fQRS(+), UA: 6.56+-1.20 mg/dL, fQRS(-), UA: 5.63+-1.49 mg/dL, p6.320 pg/mL, UA: 6.56+-1.27 mg/dL, galectin-3 ≤6.310 pg/mL, p=0.016; left atrium anterior-posterior dimension (LAAPD) >36 mm, UA: 6.31+-1.33 mg/dL, LAAPD

Objective Micro T-wave alternans (MTWA) has been associated with poor arrhythmic prognosis in various cardiac disorders. The aim of this study was to assess the relationship between the presence of MTWA and the predicted 5-year risk of sudden cardiac death (HCM Risk-SCD) among patients with hypertrophic cardiomyopathy (HCM). Methods A total of 117 consecutive HCM patients were included in this prospective observational study. Patients were divided into two groups, according to the presence [MTWA (+) group (n=44)] or absence [MTWA (-) group (n=73)] of MTWA on ambulatory (Holter) electrocardiography. Results The risk of HCM Risk-SCD (%), the rate of high-risk patients (HCM Risk-ECG >6%), the requirement for cardiopulmonary resuscitation, and implanted cardioverter defibrillator therapy, the percentage of some clinical, echocardiographic, and Holter findings were all statistically higher in the MTWA (+) group than in the MTWA (-) group (all p 4.9% was identified as an effective cutoff point in the MTWA (+) for HCM. The HCM Risk-SCD value of more than 4.9 yielded a sensitivity of 93.2% and a specificity of 84.5%. Conclusion The presence of the MTWA on ambulatory electrocardiogram seems to be significantly associated with increasing percentages of the predicted HCM Risk-SCD score in patients with HCM. The MTWA was determined as an independent high-risk indicator for HCM Risk-SCD.

Simultaneous multivessel epicardial coronary artery thrombosis is an uncommon finding in acute ST-segment elevation myocardial infarction (STEMI). It generally leads to cardiogenic shock and sudden cardiac death in the hospital. We report a 42-year-old male patient presenting with acute anterior STEMI with triple coronary artery thrombosis. An emergency coronary angiogram showed total occlusion of the left anterior descending artery (LAD) with thrombus formation. At the same time, thrombus formations were also seen in the circumflex artery (CXA), the second obtuse marginal (OM2) branch, and the distal right coronary artery (RCA). We unsuccessfully attempted thrombus aspiration of the LAD. Subsequently, we decided to stent the LAD, and a successful percutaneous coronary intervention (PCI) was performed for the LAD. In a second procedure, RCA thrombosis regressed with 24-hour tirofiban (glycoprotein IIb/IIIa receptor inhibitor) perfusion, although CXA thrombosis and OM thrombosis did not regress. Therefore, we performed stenting of the CXA and OM with a newer provisional technique called the flower petal technique. Thrombolysis in myocardial infarction (TIMI) flow grade III was seen after stenting. The patient was discharged from the hospital 5 days after PCI without any symptoms.

The prognostic value of pentraxin 3 (PTX3) has been documented in patients with acute coronary syndrome. However, its long-term prognostic value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. The aim of this study was to evaluate the prognostic value of PTX3 in patients with STEMI undergoing a primary percutaneous coronary intervention (PCI).We prospectively enrolled 499 consecutive STEMI patients undergoing primary PCI. The high-PTX3 group (n=141) was defined as having values in the third tertile (≥3.2 ng/ml) and the low-PTX3 group (n=358) included patients with values in the lower two tertiles (3.2 ng/ml).The patients in the high-PTX3 group were older (mean age 54.3±11.8 vs. 58.5±13.1 years, P=0.002). Higher in-hospital cardiovascular mortality and 2-year all-cause mortality rates were observed in the high-PTX3 group (9.9 vs. 2.8%, respectively, P0.001; 21 vs. 6.2%, respectively, P0.001). In a Cox multivariate analysis, a high admission PTX3 value (3.2 ng/ml) was found to be an independent predictor of 2-year all-cause mortality (odds ratio: 2.3, 95% confidence interval: 1.20-4.90, P=0.025).These results suggest that a high admission PTX3 level was associated with increased in-hospital cardiovascular mortality and 2-year all-cause mortality in patients with STEMI undergoing primary PCI.

The use of contraband cigarettes is a serious public health problem. We present a case of atrial fibrillation in a healthy adolescent suspected to be caused by smoking contraband cigarettes. A 15-year-old man was admitted to our emergency department experiencing syncope and palpitations. He was a cigarette smoker, but he had never smoked any illicit tobacco products before. He had finished a pack of counterfeit cigarettes (20 pieces) in 1.5 h. His electrocardiogram showed atrial fibrillation with a rapid ventricular response and irregular RR intervals. The patient had no history of alcohol use, surgery, palpitations, hypertension, chronic bronchitis, or any infectious diseases. His atrial fibrillation was converted to a normal sinus rhythm after the cardioversion treatment. Our patient was discharged from the pediatric cardiology service and advised to quit smoking cigarettes, strictly warning against illicit tobacco products. In conclusion, intensive smoking of counterfeit cigarettes may lead to occurrences of atrial fibrillation.

Abstract. Background: The aim of this study was to assess the periprocedural and one-year outcomes of two different cerebral protection systems used during carotid artery stenting (CAS). Patients and methods: We enrolled 90 consecutive patients with carotid artery stenosis who underwent CAS with a proximal flow blockage protection system (mean age 69.7 ± 8) or distal protection with a filter (mean age 70.8 ± 7). Results: CAS was performed successively on 89 patients (99 %). Adverse events were defined as major stroke, minor stroke, transient ischemic attack (TIA), myocardial infarction, and death. Two strokes, one TIA, one death, and one myocardial infarction were observed in-hospital. There were no significant differences in safety or benefits between the proximal flow blockage embolic protection system (n = 45) and the distal filter protection system (n = 45) in terms of clinically apparent cerebral embolism, TIA, death, or myocardial infarction during the periprocedural stage or during the one-year follow-up period. Conclusions: Although it has been shown that the proximal flow blockage cerebral protection system decreases the risk of silent cerebral embolism, it has no advantage over the distal filter protection system in terms of adverse cerebrovascular or cardiac events during the periprocedural stage or during the long-term follow-up period.

Ozyilmaz, Sinem/0000-0003-4829-8400 WOS: 000366307800014 PubMed ID: 25179317 Background: The risk of thrombus formation in the left atrium is known to be very high in patients with both mitral stenosis (MS) and atrial fibrillation (AF). However, that risk should not be ignored in patients with MS in sinus rhythm (SR). The aim of this study was to determine the clinical, echocardiographic, and biochemical factors that could have a determining role in the formation of a left atrial (LA) thrombus in patients with MS in SR. Method: A total of 207 consecutive patients with MS who underwent both transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) for diagnosis or to investigate the presence of a thrombus in the LA and appendage were enrolled in this study. Results: LA thrombus was detected in 21 of 207 patients. CHA(2)DS(2)-VASc score was not found to be a predictor of LA thrombosis in patients with MS in SR, despite the higher CHA(2)DS(2)-VASc scores observed in those patients. The mitral valve area and mitral valve gradient were not predictive of LA thrombus development; however, LA anteroposterior diameter (LAAPD) was found to be a predictor of LA thrombosis. Levels of high sensitivity-C-reactive protein and uric acid were higher in the patients with LA thrombosis, but only uric acid was found to be a predictor of LA thrombosis in multivariate analysis. Conclusions: A larger LAAPD and an elevated serum uric acid level were found to be independent predictors of LA thrombosis in patients with MS in SR.

Objective We evaluated autonomic behavior by examining heart rate variability (HRV) in the time domain and frequency domain in pediatric patients who underwent transcatheter closure of atrial septal defect (ASD). Methods A prospective study design was used. Holter ECG was performed in a control group of 30 healthy subjects and a group of 47 patients who underwent transcatheter ASD closure. ECG was taken one day before, one day after, and six months after the procedure to evaluate changes in the time domain [SDNN, rMSSD, NN, pNN50(%), and SDANN] and frequency domain (VLF, LF, HF, VHF, and LF/HF) in the patient group. Student's t-test was used to evaluate changes prior to and after the procedure. Results There were 28 females (60%) in the patient group and 21 females (70%) in the control group. The mean age and weight of the participants in the patient group were 9.61±4.72 years and 32.40±19.60 kg, respectively; the mean age and weight of the control subjects were 10.43±5.31 years and 32.83±13.00 kg, respectively. In both the time domain and frequency domain analyses, the patient group values were found to be lower than those in the control group prior to the procedure; the values in the patient group were found to approach the values in the control group following the procedure. By the sixth month, the values in the patient group reached the control levels with no statistically significant difference (SDNN: 145±0.84, 137.50±42.50; rMSSD: 72.18±48.22, 58.14±28.49; SDANN: 125.13±13.50, 122.40±41.06; VLF: 112.85±29.07, 114.41±98.39; LF: 50.40±24.09, 45.69±15.13; HF: 39.28±19.86, 44.29±13.14; VHF: 10.29±4.24, 9.99±6.47; LF/HF: 1.90±1.44, 1.24±0.81; p>0.05). Conclusion The transcatheter closure of secundum ASDs was found to have a positive effect on HRV. Consequently, it may contribute to reduced mortality and morbidity. We can conclude that in children, HRV recovers approximately six months after transcatheter ASD closure.

Objective: The aim of this study was to assess subclinical left (LV) and right ventricular (RV) dysfunction novel load-independent isovolumic myocardial acceleration (IVA) derived from tissue Doppler imaging (TDI) in patient with metabolic syndrome (MetS). Methods: This study had an observational case-control design. The study included 133 subjects which were divided into two groups: 75 patients with MetS and 58 controls without MetS. MetS was defined by the presence of ≥3 criteria according to ATP-NCEP III guidelines. All the subjects underwent laboratory blood tests and complete conventional echocardiography and TDI. Student’s t, Mann-Whitney U, Pearson’s, and multiple regression analysis were used for statistical analysis. Results: There were no significant difference between two groups in terms of traditional echocardiographic parameters. The diastolic and global functions of both ventricles were significantly impaired in MetS group. The TDI-derived IVA of the LV and the RV was significantly lower in patients with MetS (3.2±0.9 vs. 4.0±1.4, p

Objective: It has been shown that the presence of fragmented QRS (fQRS) is associated with poor prognosis in many cardiovascular diseases and in patients with hypertrophic cardiomyopathy (HCM). However, no study has shown an association with the absolute risk score of sudden cardiac death. The aim of this study was to determine the relationship between QRS and the predicted risk score of sudden cardiac death at 5 years (HCM Risk-SCD) in HCM patients. Methods: In total, 115 consecutive HCM patients were included in this prospective observational study. The patients were divided into two groups according to the presence [fQRS(+) group (n= 65)] or absence [fQRS(-) group (n= 50)] of fQRS on a 12-lead electrocardiogram (ECG). Results: The HCM Risk-SCD (%) HCM Risk-SCD (>6%) values and some echocardiographic parameters, including ventricular extrasystole, ventricular tachycardia, cardiopulmonary resuscitation, implantable cardioverter defibrillator implantation, appropriate shock, and heart failure at the time of admission, were significantly higher in the fQRS(+) group than in the fQRS(-) group (all p4 was identified as an effective cut-off point in fQRS for HCM. An HCM Risk-SCD value of >4 yielded a sensitivity of 77% and a specificity of 76%. Conclusion: fQRS is determined to be an independent high-risk indicator of HCM Risk-SCD. It seems to be associated with increased ventricular arrhythmias and some echocardiographic parameters.

Background: Although it has declined in developed countries, mitral valve stenosis is problematic in developing countries; its main cause is rheumatic fever. In patients with rheumatic mitral stenosis (RMS), ongoing chronic inflammation may resultin the progression of valvular damage and the formation of spontaneous echocardiographic contrast (SEC). Aim: We investigated the role of the neutrophil/lymphocyte ratio (NLR) as an indicator of ongoing inflammation and independentpredictive risk factor for SEC in RMS patients. Methods: A total of 112 patients (mean age 46 ± 10.6; 73.2% female) with RMS who underwent both transthoracic echocardiography and transoesophageal echocardiography were enrolled; the control group comprised 100 healthy volunteers (mean age 44 ± 9.1; 62% female). Patients were divided into two subgroups according to the formation of SEC in the left atrium and appendage. Haematological and biochemical indices were measured in all patients and controls. Result: NLR was higher in the patients than controls (2.6 ± 1.15 vs. 1.71 ± 0.53, p < 0.001). In addition, it was higher in the SEC-positive group (mean age 47 ± 10.3; 68.4% female) compared to the SEC-negative group (mean age 44 ± 10.7; 78.2% female; 3.21 ± 1.25 vs. 1.97 ± 0.55, p < 0.001). In multivariate analysis, NLR (odds ratio [OR] 20.602, 95% confidence interval [CI] 4.678–90.731; p < 0.001) and left atrial diameter (OR 5.966, 95% CI 2.166–16.429; p = 0.01) were found tobe independent predictors of SEC in RMS patients. Conclusions: RMS patients exhibit on-going inflammation; NLR is a good marker of this. The formation of SEC is associated with inflammation and NLR is an independent predictive risk factor for SEC.

Junctional ectopic tachycardia(JET) is a rare childhood arrhythmia originating from the area adjacent to the atrioventricular(AV) node. It often occurs after surgical procedures like repair of Tetralogy of Fallot, atrioventricular septal defect and ventricular septal defect, which are all performed in that area. While AV block (AVB) can occur after JET, it is very rare for late JET occurring after early postoperative AVB to be followed by normal sinus rhythm (NSR). There is no information in the literature related to the pathophysiology of this phenomenon. In this text, we present 4 patients who developed complete AV block(CAVB) in the early postoperative period (within the first 24h) after JET in late period (>72h) and returned to NSR with first-degree AV block and then NSR during follow-up. Based on these cases, we hypothesize that there is a link between late JET after early postoperative CAVB and return to NSR.

OBJECTIVES Galectin-3 is a marker associated with myocardial fibrosis and left ventricular myocardial index (LVMI). Myocardial fibrosis and LVMI have been reported in many studies to be associated with microvolt T-wave alternans (MTWA) positivity. In this study, galectin-3 levels of normotensive individuals and sustained systolic-diastolic hypertensive patients were compared and the association between galectin-3 levels and ambulatory ECG-based MTWA was investigated. METHODS A total of 184 individuals were included in the study, among whom, 43 were normotensive and 141 had sustained systolic-diastolic hypertension without cardiovascular or chronic renal failure. Galectin-3, MTWA, and LVMI were evaluated in all participants. Galectin-3 levels of hypertensive and normotensive participants were compared. The association between galectin-3, MTWA, LVMI, and estimated glomerular filtration rate (eGFR) was investigated in hypertensive patients. RESULTS LVMI and galectin-3 levels were higher among hypertensive patients compared with normotensives (94.9±26.8 vs. 76.4±22.9 g/m, 7.325±2.123 vs. 5.233±1.506 ng/ml; P

Objective: Our aim was to assess the value of coronary artery calcium score (CACS) in the early diagnosis of coronary artery disease in Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage II chronic obstructive pulmonary disease (COPD) patients and to identify high-risk patients. Methods: Forty-two patients with GOLD stage II COPD and 31 healthy control subjects were enrolled in the study. This study was designed as a prospective observational cross-sectional study. Pearson’s correlation coefficient was used for comparisons between groups. Criteria for stage II COPD diagnosis were forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of

Levels of galectin-3, a member of a family of soluble β-galactoside-binding lectins, are reported to be higher in patients with type 2 diabetes mellitus (DM) and metabolic syndrome. Conflicting results exist on the effects of galectin-3 in diabetic patients. The aim of this study was to investigate the relationship between galectin-3 levels and coronary artery disease (CAD), coronary plaque burden, and plaque structures in patients with type 2 DM.A total of 158 consecutive patients with type 2 DM undergoing planned coronary computed tomography angiography (CCTA) were included in this study. The study population was divided into CAD and non-CAD groups according to the presence of CCTA-determined coronary atherosclerosis.Galectin-3 concentrations were significantly higher in the CAD group than in the non-CAD group (1412.0 ± 441.7 vs. 830.2 ± 434.9 pg/ml, P0.001). Galectin-3 levels were correlated positively with BMI, high-sensitivity C-reactive protein, the total number of diseased vessels, the number of plaques (all, P0.001), and the calcified plaque type (P = 0.001). In addition, galectin-3 levels were found to be a significant independent predictor of coronary atherosclerosis in type 2 diabetic patients (P = 021; odds ratio, 1.002; 95% confidence interval, 1.000-1.003).Galectin-3 is a novel, promising biomarker that may help identify type 2 diabetic patients who may require early CAD intervention because of the potential risk of coronary atherosclerosis.

Aims Atrial septal defect (ASD) is one of the most common congenital heart diseases in adults. We prospectively evaluated early and mid-term effects of the percutaneous closure of secundum ASD on atrial electromechanical delay (AEMD) and left atrial (LA) mechanical functions at the first day and sixth month in patients undergoing percutaneous closure. Methods and results Forty-one patients were included in this study. Twenty-six (63.4%) of the 41 patients were female and the mean age was 41 ± 13 years. All the patients had echocardiographic examination before the procedure and at the first day and sixth month after the procedure. LA volumes (maximal, minimal, and presystolic) and EMD (lateral, septal, and tricuspid) were measured. Left and right intra- and inter-AEMD were not changed at the first day but both were significantly shorter at the sixth month. There was no change in the total emptying volume and fraction before and after the procedure. LA maximal, minimal, and pre-systolic volumes, active emptying volume, and fractions were decreased at the first day and at the sixth month compared with pre-procedural volumes. LA passive emptying volume, passive emptying fraction, and conduit volume were increased at the first day and at the sixth month compared with pre-procedural volumes. Conclusion Our results revealed that there was no change in the LA mechanical reservoir functions, but improved conduit function and impaired contractility functions early and in the mid-term after percutaneous closure of ASD and decreased AEMD only in the mid-term.

Aim: The aim of this study was to assess subclinical the left and right ventricular dysfunction by using novel load-independent tissue Doppler imaging (TDI) derived isovolumic myocardial acceleration (IVA) in metabolic syndrome (MetS) patients and the association of this impairment with the number of MetS components. Methods: The study included 133 subjects divided into two groups: 75 patients with MetS and a control group (n 1⁄4 58) without MetS. MetS was defined by the presence of 3 ATP-NCEP III criteria. All the subjects underwent laboratory blood tests and complete conventional echocardiography and TDI. Results: There were no significant changes in traditional echocardiographic parameters. The diastolic and global functions of both ventricles (early (E') and late (A') diastolic velocities, E'/A' ratio, myocardial performance index) were significantly impaired (p 0.05 for all). The IVA of the LV was inversely correlated with the patient's waist circumference (r1⁄4 -0.28, p1⁄40.001), triglyceride levels (r1⁄4 -0.22, p1⁄40.014), and the number of risk factors (r1⁄4 0.28, p1⁄40.001). The RV IVA was inversely correlated with diastolic blood pressure (r1⁄4 -0.37, p1⁄4

PP-266 Coronary artery disease (CAD) is a common health problem and the leading cause of death in Turkey. Many studies have shown the relationship between risk factors and CAD development and severity. In this study group of Turkish patients who underwent coronary angiography, we aimed to determine
