Purpose: The effects of different COVID-19 therapeutic strategies on cardiac function are uncertain. Therefore, this study aimed to evaluate the effects of different medical treatments on biventricular function in patients who had recovered from COVID-19. Materials and Methods: Speckle-tracking echocardiography was performed to examine the biventricular myocardial function of patients at follow-up visits after recovery from COVID-19. The patients were divided into two groups based on the medication they used during the active disease: favipiravir (FAV; n = 60) or hydroxychloroquine (HCQ; n = 60). A comparison was made with risk factor–matched controls (n = 41). Results: A total of 161 patients were included in the study. The left ventricular end-diastolic volume, end-systolic volume, end-diastolic diameter, and end-systolic diameter were higher in the HCQ and FAV groups compared to the controls, while the left ventricular ejection fraction was similar between all the groups. The right ventricular diameter was increased, and the systolic pulmonary artery pressure was higher in the HCQ and FAV groups compared to the controls. The left ventricular global longitudinal strain (-18±6.6 vs. -19.7±4.4 vs. -20.4±5, respectively), the right ventricular global longitudinal strain (-19.8±7.5 vs. -22.2±6 vs. -23.4±6.2, respectively), and the right ventricular free wall strain (-16.9±3.6 vs. -18.2±2.4 vs. -19.6±4.7, respectively) were worse in the HCQ group compared to the FAV and control groups. Conclusion: This study found echocardiographic evidence of subclinical cardiac involvement in both the HCQ and FAV groups compared to the controls. However, HCQ treatment was associated with an increased risk of biventricular subclinical systolic dysfunction in COVID-19 survivors compared with FAV treatment.

SUMMARY Dilated cardiomyopathy (DCM) is characterized by systolic dysfunction and is usually idiopathic. A rare cause of reversible DCM is hypocalcemia. Calcium plays a key role in myocardial contraction. Hypocalcemia can lead to a decrease in contraction, left ventricular systolic dysfunction, and heart failure with reduced ejection fraction (EF). Hypocalcemia-related reversible DCM reports are rare. Herein, we present two cases with heart failure caused by hypocalcemia developed due to hypoparathyroidism. The first case presented with severe heart failure and an extremely low serum calcium level (4.4 mg/dL) due to idiopathic hypoparathyroidism. The second case, which was also admitted with heart failure due to hypocalcemia, had iatrogenic hypoparathyroidism due to a subtotal thyroidectomy. In both cases, patients had reduced left ventricular systolic functions (EF was 33% and 42%, respectively). After calcium replacement and heart failure treatment, calcium levels were normalized. A significant and rapid improvement in heart failure was achieved in both cases (EF 60% and 50%, respectively). Serum calcium levels should always be measured in patients with heart failure, and the etiology of hypocalcemia should be sought. In addition to the standard pharmacotherapy of heart failure with reduced EF, calcium supplementation is essential for treating these patients.

Abstract Introduction We evaluated several biological indicators based on inflammation and/or nutritional status, such as systemic immune-inflammation index (SII), early warning score (ANDC) and prognostic nutritional index (PNI) in hospitalized COVID-19 patients with and without malignancies for a prognostic significance. Methodology This is a retrospective and observational study on 186 patients with SARS-CoV-2, who were diagnosed with COVID-19 by real-time PCR testing and hospitalized due to COVID-19 pneumonia. 75 patients had various malignancies, and the rest (111), having a similar age and comorbidity profile based on propensity score matching, had no malignancy. Results None of the measures as neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, monocyte to lymphocyte ratio, SII, PNI or ANDC was found to be significantly different between two groups. Odds ratio for the mortality, OR 2.39 (%95 CI 1.80–3.16) was found to be significantly higher for the malignancy group, even though the duration of hospitalization was statistically similar for both groups. PNI was found to be significantly lower for deceased patients compared with survivors in the malignancy group. Contrarily, ANDC was found to be significantly higher for deceased patients in the malignancy group. Conclusions PNI and ANDC have independent predictive power on determining the in-hospital death in COVID-19 malignancy cases. It is suggested that ANDC seems to be a more sensitive score than SII in COVID-19 cases with malignancies.

Objective: The aim of this cross-sectional, retrospective, descriptive study was to review and classify cardiac masses systematically and to determine their frequencies. Methods: The medical records of 64,862 consecutive patients were investigated within 12 years. Every patient with a cardiac mass imaged by transthoracic echocardiography (TTE) and confirmed with an advanced imaging modality such as transesophageal echocardiography (TEE), computed tomography (CT) and/or cardiac magnetic resonance imaging (CMR) was included. Acute coronary syndromes triggering thrombus formation, vegetations, intracardiac device and catheter related thrombi were excluded. Results: Data demonstrated 127 (0.195%) intracardiac masses consisting of 33 (0.050%) primary benign, 3 (0.004%) primary malignant, 20 (0.030%) secondary tumors, 3 (0.004%) hydatid cysts and 68 (0.104%) thrombi respectively. The majority of primary cardiac tumors were benign (91.67%), predominantly myxomas (78.79%), and the less malignant (8.33%). Secondary cardiac tumors were common than the primary malignant tumors (20:3), with male dominancy (55%), lymphoma and lung cancers were the most frequent. Intracardiac thrombi was the majority of the cardiac masses, thrombi accompanying malignancies were in the first range (n = 17, 25%), followed by autoimmune diseases (n = 13, 19.12%) and ischemic heart disease with low ejection fraction (n = 12, 17.65%). Conclusions: This retrospective analysis identified 127 patients with cardiac masses. The majority of benign tumors were myxoma, the most common tumors that metastasized to the heart were lymphoma and lung cancers, and the thrombi associated with malignancies and autoimmune diseases were the most frequent.

Abstract Background T‐wave peak‐to‐end interval (TPEI) is a measure of repolarization dispersion on surface electrocardiogram (ECG). TPEI has been reported as a prognostic parameter with heart disorders. In this study, we aimed to evaluate the relationship between echocardiogram‐derived right heart parameters, right heart catheterization (RHC) measurements, and TPEI in patients with precapillary pulmonary arterial hypertension (PAH). Methods Thirty‐eight patients (29 females and 9 males, mean age of 54.9 ± 10.9 years) who had undergone RHC for a preliminary diagnosis of pulmonary hypertension (PH) were included in the study. We performed transthoracic echocardiography (TTE), and resting 12‐lead ECG was recorded before RHC. TPEI was measured from leads of V1‐V6, DII, DIII, and aVF, and these values are averaged to obtain the global TPEI. Results Duration of TPEI was significantly correlated with mean PAP, pulmonary vascular resistance (PVR), and cardiac index (CI). Longer TPEI was associated with higher N terminal probrain natriuretic peptide (NT pro‐BNP) level, lower 6‐min walk distance (6MWD), and lower tricuspid annular plane systolic excursion (TAPSE). Conclusion Prolongation of TPEI could be a new predictor of adverse outcome in PAH and may provide additional prognostic information for patients with PAH.

- Abstract
Background: Long non-coding RNAs (lncRNAs) play important roles in cellular processes and disease pathogenesis. In this study, we aimed to show the relationships and possible effects of the expression level of two lncRNAs in acute myocardial infarction (AMI) in circulating leukocytes. Methods and Results: In this case-control study, the relationship between AMI and expression levels of two candidate lncRNAs, called BAT5 (HLA-B-Associated Transcript 5) and IL21R-AS1 (IL21R antisense RNA 1), in 231 patients who underwent percutaneous coronary interventions were investigated. Expression levels of lncRNAs in leukocytes were measured by quantitative real-time PCR (qRT-PCR). The m6A modification regions and subcellular localizations of these lncRNAs were predicted by in silico analysis. Routine biochemical and immunoassay analyzes were performed on Roche Cobas 8000/e701 integrated automated analyzer with their original kits. Ranked ANCOVA tests were used to compare expression levels of lncRNAs between groups after adjusting for gender and use of cardiovascular drugs. The crude and adjusted expression levels of BAT5 and IL21R-AS1 in leukocytes of AMI patients (n=128) were found to decrease compared to the control cases (n=103) (p6A modification regions of BAT5 and IL21R-AS1 transcripts was determined as 5 and 4, respectively. Conclusion: This study indicates that the decreased expression levels of BAT5 and IL21R-AS1 are associated with the occurrence of acute myocardial infarction in individuals.

BACKGROUND Ventricular scars due to myocardial infarction provide a substrate for ventricular arrhythmias, and cardiac magnetic resonance (CMR) is the golden standard for the quantification of scar tissue magnitude. CMR has still limitations with patients with ICD despite ICD's becoming MR-compatible. We investigated the association between calibrated integrated backscatter (cIBS) and arrhythmia frequency in patients with ICD. METHODS Thirty-two ischemic dilated cardiomyopathy (ICM) patients with VVI-ICD (mean age 66.56 ± 9.05, 28 male, and four female) were divided into three groups according to their arrhythmia frequency (ventricular arrhythmia-[VA -], VA + [VA +], and arrhythmia storm [AS]). Then with transthoracic echocardiography (TTE), all patients' cIBS values were calculated and these values were compared with the patients' arrhythmia frequency. RESULTS cIBS values of patients with VA + and AS were significantly higher in the apical-septal (0.66 ± 0.11 vs. 0.50 ± 0.16, p = .008) and apical-lateral (0.62 ± 0.19 vs. 0.46 ± 0.18, p = .041) segments compared to those of patients with VA -. The cIBS values of apical-septal (0.50 ± 0.16 vs. 0.65 ± 0.08 vs. 0.66 ± 0.13 respectively, p = .032) and apical-anterior (0.53 ± 0.22 vs. 0.48 ± 0.17 vs. 0.79 ± 0.23 respectively, p = .03) segments were significantly different between the groups. Furthermore, in the post hoc analysis, the difference was significantly higher in VA + than VA - in the apical-septal segment and higher in AS than VA + in apical-anterior segments. CONCLUSION Our findings suggest an association between the cIBS values and arrhythmia frequency in the study group.

Introduction Behçet’s disease (BD) is a chronic inflammatory disease which can be limited to only mucocutaneous tissues or can affect different systems of the body. Aim To investigate the association of endothelial and erectile dysfunctions with BD, on the basis of comparative analysis between mucocutaneous and systemic BD. Material and methods Thirty-eight men diagnosed with BD were included in the present study. The patients were stratified into two groups as mucocutaneous BD (n = 20, MBD group), and systemic BD (n = 18, SBD group). Erectile dysfunction (ED) was assessed using the Erectile Function domain of the International Index of Erectile Function (IIEF-EF) questionnaire. The coronary flow reserve (CFR) assessment was done for analysing endothelial dysfunction (EnD), and CFR < 2 was defined as EnD. Penile Doppler ultrasonography (PDU) was performed for ED. The demographic and clinical parameters, IIEF-EF score ED classification, CFR and PDU test findings were compared between two groups. Results The median age was 34 (22–52) years in the overall population, and there was no difference between two groups (p = 0.558). Time from diagnosis was significantly longer (24 vs. 102 months, p = 0.021) and the use of immunosuppressive therapies was higher (0 vs. 70.6%, p < 0.001) in the SBD group. In overall, median CFR was 1.92 (1.1–5.96), and there was no difference between two groups (1.88 vs. 1.97, p = 0.812). The percentage of patients with CFR < 2 was similar in two groups (52.6% vs. 52.9%, p = 0.985). The ED status according to IIEF-EF was similar in two groups (45% vs. 27.8%, p = 0.538) as well as according to PDU analyses (10% vs. 16.7%, p = 0.544). Conclusions The increased risk of endothelial, and erectile dysfunctions should be considered in men who were diagnosed with mucocutaneous and systemic BD.

IntroductionVitamin D (VD) deficiency is a common disease that occurs in all stages of life. A growing number of studies call attention to the relationship between VD deficiency and cardiovascular disease. The aim of this study was to investigate the effect of VD on subclinical left ventricular (LV) function in diabetic and non-diabetic patients with no significant coronary artery disease.Material and methodsWe recruited 140 patients (80 diabetics and 60 non-diabetics) with symptoms of stable ischemic heart disease who underwent coronary angiography and who had no significant coronary artery disease in our clinic. The 25(OH)D3 levels were measured and patients who had 25-(OH)D3 levels below 20 ng/dl were defined as the VD deficient group. In addition to conventional echocardiographic parameters, tissue Doppler echocardiography was used for LV diastolic functions and 2D speckle tracking strain echocardiography (2D STE) for evaluating the longitudinal deformation indices of the LV myocardium.ResultsIn all groups, LV global longitudinal strain (GLS) was significantly impaired in patients with VD deficiency (p < 0.001) compared to patients without VD deficiency. LV global longitudinal strain rate (GLSR) was significantly impaired in patients with VD deficiency (p = 0.003). The GLS was negatively associated with 25-(OH)D3 in the VD deficiency group (r = –0.52623, p < 0.001). Conversely, GLS was positively associated with 25-(OH)D3 levels in the normal VD group (r = 0.28, p = 0.048).ConclusionsVD deficiency is associated with impaired myocardial GLS. The present study demonstrated that VD deficiency may be the cause of subclinical myocardial dysfunction in patients with or without diabetes mellitus and no history of significant coronary artery disease.

Subclinical atherosclerosis and cardiovascular events are common even in young normotensive patients with autosomal dominant polycystic kidney disease (ADPKD). Our aim was to examine the relationship between serum fibroblast growth factor-23 (FGF-23) levels, left ventricular global longitudinal strain (LV-GLS), arterial stiffness (AS), and carotid intima-media thickness (CIMT) in patients with ADPKD with preserved kidney function. The relationship between albuminuria, AS, LV-GLS, CIMT, 24-hour ambulatory blood pressure measurement, and FGF-23 was examined in 52 normotensive and hypertensive patients with ADPKD and a matched control group of 35 subjects. AS was assesed with brachial-ankle pulse wave velocity, LV-GLS was measured with speckle-tracking echocardiography. FGF-23 was measured with enzyme-linked immunosorbent assay. The microalbumin/creatinine ratio was significantly higher in the ADPKD group than in the control group (p?0.001). Serum FGF-23 levels were similar between the study and control group. LV-GLS value tended to be impaired and CIMT to be higher in the ADPKD group compared to controls (?18.1?±?2.6 vs. -19.4?±?3.1?%, p?=?0.08; 0.75?±?0.1 vs. 0.68?±?0.1 mm, p?=?0.09, respectively). The augmentation index was significantly higher in the ADPKD group than in the control group (26.2?±?12.5 vs. 16.4?±?11.2 mmHg/mmHg, p?=?0.01). Our study supports subclinical impairment in arterial and cardiac functions in the early period of ADPKD. However, none of these factors was found to be associated with serum FGF-23 levels.

- Abstract
Background The novel coronavirus infection (COVID-19) disease has spread rapidly and posed a great threat to global public health. The laboratory parameters and clinical outcomes of the disease in discharged patients remain unknown. In this study, we aimed to investigate the laboratory and echocardiographic findings of patients with COVID-19 after discharge and the relation between left ventricular global longitudinal strain (LVGLS) and inflammatory parameters in discharged patients. Methods A total of 75 patients recovering from COVID-19 as the study group were prospectively recruited from the COVID-19 outpatient clinic for their follow-up visits at a median 6 months after discharge. Patients were classified into groups according to pneumonia severity and impairment in LVGLS. Laboratory findings of patients both at admission and after discharge were evaluated and the relation with pneumonia severity at admission and LVGLS after discharge were analyzed. Results Serum ferritin, lactate dehydrogenase (LDH) and prohormone B-type natriuretic peptide (pro-BNP) levels after discharge were significantly higher in the study group than the control group (n = 44). Ferritin was found to be related to pneumonia severity. Serum ferritin and LDH values after discharge were significantly higher in patients with impaired LVGLS than those with preserved. There was a significant correlation between LVGLS, serum ferritin and LDH values after discharge (r = -0.252, p = 0.012; r = -0.268, p = 0.005, respectively). Conclusions Clinicians should pay close attention to the serum ferritin and LDH levels in discharged patients for predicting the severity of COVID-19 disease and early identification of subclinical left ventricular myocardial dysfunction.

Background T‐wave peak‐to‐end interval (TPEI) is a measure of repolarization dispersion on surface electrocardiogram (ECG). TPEI has been reported as a prognostic parameter with heart disorders. In this study, we aimed to evaluate the relationship between echocardiogram‐derived right heart parameters, right heart catheterization (RHC) measurements, and TPEI in patients with precapillary pulmonary arterial hypertension (PAH). Methods Thirty‐eight patients (29 females and 9 males, mean age of 54.9 ± 10.9 years) who had undergone RHC for a preliminary diagnosis of pulmonary hypertension (PH) were included in the study. We performed transthoracic echocardiography (TTE), and resting 12‐lead ECG was recorded before RHC. TPEI was measured from leads of V1‐V6, DII, DIII, and aVF, and these values are averaged to obtain the global TPEI. Results Duration of TPEI was significantly correlated with mean PAP, pulmonary vascular resistance (PVR), and cardiac index (CI). Longer TPEI was associated with higher N terminal probrain natriuretic peptide (NT pro‐BNP) level, lower 6‐min walk distance (6MWD), and lower tricuspid annular plane systolic excursion (TAPSE). Conclusion Prolongation of TPEI could be a new predictor of adverse outcome in PAH and may provide additional prognostic information for patients with PAH.

Fibrinolysis is an option for the management of mechanical prosthetic valve thrombosis when surgery has prohibitive risks. Current guidelines suggest recombinant tissue plasminogen activator (not to exceed 100 mg) with unfractionated heparin. A low-dose (25 mg) alteplase regimen as treatment in patients with a high risk of bleeding warrants further research. This report describes the case of a 65-year-old woman with a history of mechanical prosthetic mitral valve replacement who was diagnosed with signet ring cell adenocarcinoma of the stomach and obstructive mechanical prosthetic thrombosis on echocardiogram. Details of challenging aspects of this case and the use of modified fibrinolytic therapy are provided.

Pulmonary hypertension (PH) is a fatal disease although significant improvements in treatment are achieved. Easily implemented and noninvasive prognostic techniques are needed while following-up these patients. The aim was to investigate the role of fractional exhaled nitric oxide (FeNO) in follow-up for patients with PH. In this longitudinal study, patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic PH (CTEPH) who were seen in PH Outpatient Clinic, Istanbul Faculty of Medicine, Istanbul University, were enrolled in the study. Echocardiography, 6-minute walking test, brain natriuretic peptide, and FeNO measurements were performed, and World Health Organization functional class was evaluated to all patients at baseline, and third, and sixth months. Right-heart catheterization and pulmonary function tests at the time of diagnosis were recorded. The study comprised 31 patients (23 women, 8 men; mean age: 53.4 ± 17.1 years) with PAH (n = 19) and CTEPH (n = 12) and 80 healthy controls. Patients with PH had lower FeNO values than the control group (16.5 ppb vs 19.8 ppb; P < .05). Fractional exhaled nitric oxide values did not change during follow-up and did not correlate with other follow-up measures except tricuspid annular plane systolic excursion values. Fractional exhaled nitric oxide was higher in the idiopathic PAH subgroup at baseline and at third month than patients with PAH associated with other diseases. Fractional exhaled nitric oxide did not change in patients who had clinical deterioration. As a conclusion; Patients with PH had lower FeNO values than healthy controls, but FeNO did not change significantly during follow-up. Large-scale studies with prolonged follow-up periods are needed to understand the role of FeNO in the follow-up of the patients with PH.

Background: Little is known about the management and mortality rates of ST-segment elevation myocardial infarction patients in developing countries. In this study, to expose independent predictors of early (24 h) in-hospital mortality and ejection fraction, we report our experience with 362 ST-segment elevation myocardial infarction patients admitted to the Istanbul Medical Faculty, Istanbul University, a tertiary referral university hospital, and treated with primary percutaneous intervention. Methods: This is a retrospective study that enrolled all patients (362) admitted with ST-segment elevation myocardial infarction to Department of Cardiology, Istanbul Medical Faculty, Istanbul University, between January 2015 and December 2016. The clinical characteristics of patients were collected retrospectively from medical chart review. Collected data were analyzed using IBM SPSS Statistics (version 21). Results: In the forward stepwise logistic regression analysis, target vessel diameter ( p = 0.001), systolic blood pressure ( p Conclusion: Our study is one of the few studies to investigate the predictors of early in-hospital mortality among patients hospitalized with ST-segment elevation myocardial infarction in a tertiary referral university hospital in a developing country. The identified predictors for mortality (including left ventricle ejection fraction and troponin T levels), left ventricle ejection fraction (including troponin T level, chest pain duration), and heart rate are consistent with what has been described in large registries in the United States and Europe.

Gölcük, Ebru (Balikesir Author), Introduction: Failure to differentiate supraventricular from ventricular arrhythmias is the most frequent cause of inappropriate implantable cardioverter-defibrillator (ICD) therapies. We hypothesized that the postpacing interval (PPI) after overdrive right ventricular pacing may differentiate ventricular (VT) from supraventricular tachycardia (SVT) such as sinus tachycardia, atrial flutter and atrial tachycardia. This hypothesis is based on the entrainment maneuver. Reentrant tachycardia circuit for VTs would haveshorter distance to RV apex than SVTs have, and the conduction time between a ventricular pacing site and the tachycardia origin is expected to be shorter in VTs than in SVTs. Methods: 220episodes from 38 patients with single chamber ICDs that RV overdrive pacing could not terminate or change the tachycardia cycle length (TCL) were retrospectively reviewed. Episodes were classified as VTs (n=115) and SVTs (n=105). TCLs, PPIs and PPI-TCL were compared between groups. Results: The cycle length of VTs was shorter than SVTs (320.6±30.3 vs 366.5±40 ms, p=0.001). PPI and PPI-TCL of VTs were shorter than SVTs (504.7±128.3 vs 689.2±121.8 ms, p=0.001, 184±103 vs 322.6±106.6 ms, p=0.001; respectively). ROC curve analysis demonstrated a 525 ms cut-off value for PPI has 89% sensitivity and 57.4% specificity to predict inappropriate ICD therapies due to SVTs (AUC:0.852). Similarly, A PPI-TCL

Background The two predominant etiologies of right ventricular tachycardia (VT) are arrhythmogenic right ventricular cardiomyopathy (ARVC) and idiopathic VT arising from the right ventricular outflow tract (RVOT). Discrimination between these two entities is critical, as their prognoses and therapeutic options differ. The Tpeak–Tend (Tpe) interval reflects the transmural repolarization dispersion and its prolongation is associated with high mortality. Methods We compared the sinus rhythm electrocardiogram (ECG) of 43 patients (24 male, 43 ± 16 years) with VT originating from right ventricle. Five patients under antiarrhythmic drug therapy were excluded. Tpe interval was measured in each precordial leads and compared among patients with ARVC and RVOT-VT. Results Twenty-five patients (16 male, 42 ± 16 years) met the Task Force criteria for the diagnosis of ARVC, and 13 patients (seven male, 45 ± 14 years) had idiopathic RVOT tachycardia. Patients with ARVC had significantly prolonged Tpe intervals in all precordial leads compared to patients with idiopathic RVOT VT (137.1 ± 32.6 ms vs 93.8 ± 16.9 ms; P < 0.001 in V1, 133.2 ± 35.5 ms vs 104.7 ± 16.9 ms; P = 0.01 in V2, 125.7 ± 31.5 ms vs 99.1 ± 19.6 ms; P = 0.09 in V3, 121.9 ± 26.5 ms vs 92.3 ± 19.7 ms; P = 0.001 in V4, 123.1 ± 26.5 ms vs 99.5 ± 20:1 ms; P = 0.04 in V5 and 126.9 ± 32.2 ms vs 89 ± 11.3 ms; P < 0.001 in V6, respectively). For the diagnosis of ARVC, Tpe cut-off value of 97 ms in V1 had 84% sensitivity and 62% specificity (area under curve = 0.880). Conclusion In patients with VT of RV origin, the prolonged Tpe interval in sinus rhythm electrocardiogram supports the diagnosis of ARVC.

Introduction: Pulmonary hypertension (PH) is a chronic, progressive disease with a high morbidity and mortality. Its pathobiology involves interacting pathways of prostacyclin (PGI2), endothelin, and nitric oxide (NO). There are few studies which evaluated exhale NO levels in patients with PH. Aim of this study was to investigate the levels of exhaled NO in PH patients. Methods: Patients who were followed in Istanbul Faculty of Medicine, Pulmonary Hypertension Outpatient Clinic were enrolled in this study. Exhaled NO levels of patients with PH were compared to age and gender matched healthy controls. Results: Data of 38 patients with PH (28 females, 10 males, age:54.5±16.3years) were compared to 80 healthy controls (55 females, 25 males, age:49.8±14.4years). Etiologies of PH were pulmonary arterial hypertension (PAH, n=24) and chronic thromboembolic pulmonary hypertension (CTEPH, n=14). NYHA functional class of the patients were mostly II (68.4%). Thirteen of them (41.9%) were given PH specific treatment (prostacyclin derivatives, endothelin receptor antagonists, phosphodiesterase inhibitors). Estimated systolic pulmonary arterial pressure (PAP) by transthoracic echocardiography was 64.9±28.2mmHg and TAPSE was 1.88±0.48. ProBNP measured 1169.2±2858.9pg/ml. Right heart catheterization revealed systolic PAP 87.1±39.4mmHg, mean PAP 55.9±25.4mmHg, PVR 7.9±5.3wood. Exhaled NO levels were lower in patients with PH than healthy controls (16.7±6.8ppb vs 19.8±7.7ppb, p=0.036). Exhaled NO levels were not different between patients with PAH and CTEPH (16.7±6 vs 16.7±7.7, p=0.458). Conclusions: Our study showed a significant reduction in exhaled NO levels in PH patients.

BACKGROUND: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp‐e) may correspond to the transmural dispersion of repolarization and that increased Tp‐e interval and Tp‐e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12‐lead surface electrocardiogram (including Tp‐e interval, Tp‐e/QT, and Tp‐e/QTc ratio) in asymptomatic ARVD patients METHODS: We selected 27 patients with asymptomatic ARVD and 27 age‐ and gender‐match young, healthy volunteers. RESULTS: Tp‐e interval, Tp‐e/QT and Tp‐e/QTc ratio were also significantly higher in ARVD group compared to the control group (all P < 0.001). There were negative correlation between S global and Tp‐e, Tp‐e/QT, Tp‐e/QTc ration (r = −0.57, P = 0.02; r = −0.85, P = 0.02; r = −0.63, P < 0.01; respectively). There were also negative correlation between Sm global and Tp‐e, Tp‐e/QT, Tp‐e/QTc ration (r = −0.61, P < 0.01; r = −0.67, P < 0.01; r = −0.68, P < 0.01; respectively). Moreover, Em global were negative correlation between Tp‐e, Tp‐e/QT, and Tp‐e/QTc (r = − 0.64, P < 0.001, r = − 0.75, P < 0.01; r = −0,69, P < 0.01; respectively) CONCLUSION: In conclusion, we have presented strong evidence suggesting that Tp‐e interval, Tp‐e/QT ratio, and Tp‐e/QTc ratio were increased in asymptomatic ARVD patients.

Introduction: Levels of adipokines in obstructive sleep apnea (OSA) and different OSA stages remains contraversial. Additionally adipokines levels in OSA with hypercapnia, pulmonary hypertension remains unknown. We examined serum levels of leptin and adiponectin in different subgroups of OSA. Methods: Obese subjects who were admitted to sleep laboratory were included. All subjects underwent spirometry, arterial blood gas analysis, polysomnography and transtoracic echocardiography. Serum levels of leptin and adiponectin were recorded. Results: Analysis included 146 OSA subjects (81 females, 65 males, age:49.8±10.7years, BMI:40.3±4.9kg/m 2 , 47.9% severe OSA). Of all subjects 37.7% had daytime hypercapnia, 61.6% had metabolic syndrome and 28.7% had pulmonary hypertension. Females had higher leptin and adiponectin levels (p 2 (p Discussion: Levels of adipokines were different especially in OSA subjects with malign obesity, female gender and severe disease.

The two predominant etiologies of right ventricular tachycardia (VT) are arrhythmogenic right ventricular cardiomyopathy (ARVC) and idiopathic VT arising from the right ventricular outflow tract (RVOT). Discrimination between these two entities is critical, as their prognoses and therapeutic options differ. The Tpeak -Tend (Tpe) interval reflects the transmural repolarization dispersion and its prolongation is associated with high mortality.We compared the sinus rhythm electrocardiogram (ECG) of 43 patients (24 male, 43 ± 16 years) with VT originating from right ventricle. Five patients under antiarrhythmic drug therapy were excluded. Tpe interval was measured in each precordial leads and compared among patients with ARVC and RVOT-VT.Twenty-five patients (16 male, 42 ± 16 years) met the Task Force criteria for the diagnosis of ARVC, and 13 patients (seven male, 45 ± 14 years) had idiopathic RVOT tachycardia. Patients with ARVC had significantly prolonged Tpe intervals in all precordial leads compared to patients with idiopathic RVOT VT (137.1 ± 32.6 ms vs 93.8 ± 16.9 ms; P0.001 in V1, 133.2 ± 35.5 ms vs 104.7 ± 16.9 ms; P = 0.01 in V2, 125.7 ± 31.5 ms vs 99.1 ± 19.6 ms; P = 0.09 in V3, 121.9 ± 26.5 ms vs 92.3 ± 19.7 ms; P = 0.001 in V4, 123.1 ± 26.5 ms vs 99.5 ± 20:1 ms; P = 0.04 in V5 and 126.9 ± 32.2 ms vs 89 ± 11.3 ms; P0.001 in V6, respectively). For the diagnosis of ARVC, Tpe cut-off value of 97 ms in V1 had 84% sensitivity and 62% specificity (area under curve = 0.880).In patients with VT of RV origin, the prolonged Tpe interval in sinus rhythm electrocardiogram supports the diagnosis of ARVC.

We evaluated whether serum omentin levels are associated with coronary artery disease (CAD) and its severity among postmenopausal women. We enrolled 193 consecutive postmenopausal women who had undergone coronary angiography for suspected stable CAD. The study population was divided into 2 groups based on the results of coronary angiography (CAD group, n = 110 and control group, n = 83). Omentin 1 levels were measured and disease severity was assessed using the SYNTAX score (SS) in the CAD group. Those patients with angiographic CAD had significantly decreased omentin 1 levels, compared to those without CAD (247.5 + 127.4 vs 506 + 246 ng/mL, P < .001). After adjusting for cardiovascular risk factors, a decreased omentin 1 level was found to be an independent predictor of both angiographic CAD and a high SS. Our data indicate that a decreased omentin 1 level is associated with CAD and its severity among postmenopausal women.

OBJECTIVE Increasing evidence suggests a relationship between vitamin D (VD) insufficiency and cardiovascular disease. The present study evaluated the effect of VD insufficiency on epicardial coronary flow rate, subclinical atherosclerosis, and endothelial function. METHODS The present study was cross-sectional and observational. We enrolled 222 consecutive patients who had undergone coronary angiography for suspected ischemic heart disease and were found to have normal or near-normal coronary arteries. Thereafter, 25(OH)D3 levels were measured and the coronary flow rate was assessed using the thrombolysis in myocardial infarction frame count. Slow coronary flow (SCF) was defined as a thrombolysis in myocardial infarction frame count greater than 27/frame. Endothelial function was assessed by brachial artery flow-mediated dilatation. Carotid intima-media thickness, an indicator of subclinical atherosclerosis, was measured using B-mode ultrasonography. RESULTS The mean level of 25(OH)D3 was 31.8 ng/ml, and 47% (n=106) of the patients had insufficient 25(OH)D levels (

Background Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12-lead surface electrocardiogram (including Tp-e interval, Tp-e/QT, and Tp-e/QTc ratio) in asymptomatic ARVD patients Methods We selected 27 patients with asymptomatic ARVD and 27 age- and gender-match young, healthy volunteers. Results Tp-e interval, Tp-e/QT and Tp-e/QTc ratio were also significantly higher in ARVD group compared to the control group (all P < 0.001). There were negative correlation between S global and Tp-e, Tp-e/QT, Tp-e/QTc ration (r = −0.57, P = 0.02; r = −0.85, P = 0.02; r = −0.63, P < 0.01; respectively). There were also negative correlation between Sm global and Tp-e, Tp-e/QT, Tp-e/QTc ration (r = −0.61, P < 0.01; r = −0.67, P < 0.01; r = −0.68, P < 0.01; respectively). Moreover, Em global were negative correlation between Tp-e, Tp-e/QT, and Tp-e/QTc (r = − 0.64, P < 0.001, r = − 0.75, P < 0.01; r = −0,69, P < 0.01; respectively) Conclusion In conclusion, we have presented strong evidence suggesting that Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio were increased in asymptomatic ARVD patients.
