Preeclampsia is a maternal disorder of pregnancy characterized by concomitant increase in preload and afterload with end organ dysfunction. The aim of our study is to evaluate left ventricular (LV) and right ventricular (RV) functions with speckle tracking echocardiography in preeclamptic patients. Fifty-five preeclamptic (mean age: 30.7 ± 5.9 years) and 35 healthy pregnant women (mean age: 28.8 ± 5.7 years) of the same race, similar age and gestational week were consecutively included. The diagnosis of preeclampsia was based on the criteria proposed by the American College of Obstetricians and Gynecologists. LV and RV functions were assessed by both conventional and speckle tracking echocardiography after the 30th gestational week and at the postpartum 6th months. The preeclamptic patients had significantly larger left atrium, thicker interventricular septum, higher systolic pulmonary artery pressure and mitral E/e′ ratio compared to controls during pregnancy while LV ejection fraction was similar. Preeclamptic patients had significantly lower LV and RV global longitudinal strain (GLS) during pregnancy compared to controls (− 18.0 ± 2.6% vs. − 19.8 ± 2.1% p = 0.001 and − 26.7 ± 3.3% vs. 28.9 ± 3.3% p = 0.002, respectively). In the postpartum period, while LVGLS values of preeclamptic patients increased significantly (− 18.0 ± 2.6% vs. − 20.4 ± 2.4% p

Objective Combination of dual antiplatelet therapy (DAPT) with glycoprotein (GP) IIb/IIIa inhibitors can increase bleeding risk. In this study, we aimed to investigate bleeding complications of different DAPTs with concomitant tirofiban use in patients with acute coronary syndrome (ACS). Methods This retrospective study included 224 consecutive ACS patients (mean age 56.6±11.1 years, 193 men) who were given conventional dose of tirofiban (25 µg/kg per 3 minutes followed by an infusion of 0.15 µg/kg/min for 24 hours) in addition to DAPT (300 mg aspirin followed by 100 mg/day + 600 mg clopidogrel followed by 75 mg/day or 180 mg ticagrelor followed by 90 mg twice daily or 60 mg prasugrel followed by 10 mg/day). Any intra-hospital bleeding complications were noted. Results Of the 224 patients, 115 were given ticagrelor and 32 were given prasugrel. Mean hemoglobin fall was similar between the patients taking ticagrelor/prasugrel and those taking clopidogrel. Ten patients taking ticagrelor and one patient taking prasugrel had hemoglobin fall ≥3 g/dL versus two patients in clopidogrel group (p=0.228). Gastrointestinal bleeding (two patients taking ticagrelor), hematoma at access site (three patients taking ticagrelor), and cardiac tamponade (two patients taking ticagrelor) rates were also similar. Creatinine levels were associated with hemoglobin fall ≥3 g/dL (p=0.032, Odds ratio 2.189, 95% confidence interval 1.070-4.479). There was no relation between hemoglobin fall ≥3 g/dL and antiplatelet agent, age, sex, hypertension, or diabetes. Conclusion Tirofiban may be given to patients receiving ticagrelor or prasugrel with a bleeding rate similar to clopidogrel. Close monitoring for bleeding risk is recommended, especially in patients with higher creatinine levels.

Although cardiovascular (CV) assessment is recommended to minimize perioperative risk in all potential kidney transplant recipients, the utility and reliability of various assessment methods are not well established. In this study, we investigated the CV evaluations and outcomes of standardized CV assessment protocols (Lisbon and American Society of Transplantation [AST]) in potential kidney transplant recipients. Data were analyzed for 266 end-stage renal disease patients (mean age 45.4 ± 13 years, female-to-male ratio 126:140) accepted for kidney transplantation wait-listing. Patients were classified as low and high cardiac risk according to their first cardiac evaluation. Major cardiovascular events (CVEs) and deaths were recorded. At the end of follow-up (median 639 days), 72 (27.1%) patients underwent kidney transplantation. A total of 49 patients (18.4%) had CVEs and 42 (15.8%) patients died. Being over 45 years of age and having dialysis vintage over 1 year were found to be independent risk factors for CVEs. Forty-eight out of 60 high-risk patients evaluated with noninvasive tests had negative results. Twelve out of these 48 patients had a CVE in due course. Among 10 patients who underwent coronary angiography, 1 had a CVE and 1 died. The sensitivity and specificity of the AST guidelines (area under the curve = 0.647, P = .005, sensitivity 83%, specificity 54%) were higher than Lisbon. In conclusion, the predictive risk factors for CVEs were age over 45 years and dialysis vintage over a year. Our results also suggest that exercise electrocardiography and myocardial perfusion scintigraphy for cardiac evaluation are less sensitive in CVE prediction. We recommend clinicians to use the AST guidelines and to prioritize coronary angiography in pretransplant CV assessment.

PURPOSE Systemic sclerosis (SSc) is associated with right ventricle (RV) remodeling and dysfunction. The primary aim of this study was to evaluate RV dyssynchrony (RV-Dys) in SSc patients using two-dimensional speckle tracking echocardiography (2D-STE). METHODS Fifty-five SSc patients with functional class I-II and 45 healthy controls were consecutively included and underwent 2D-STE. RV-Dys was defined as the standard deviation of time to peak strain of mid and basal segments of RV free wall and interventricular septum. SSc group was further classified according to the presence of pulmonary arterial hypertension (PAH). Patients with tricuspid regurgitant velocity >2.8 m/s with additional echocardiographic PAH signs were defined as SSc PAH (+). RESULTS SSc patients had lower RV longitudinal strain (RV-LS) (-17.6 ± 4.6% vs. -20.8 ± 2.8%, p

Purpose Hypertension is associated with left ventricular (LV) hypertrophy, impaired LV relaxation, and left atrial (LA) enlargement. Cardiac rehabilitation (CR) improves clinical outcomes in a broad spectrum of cardiac disease. The aim of our study was to determine the effect of CR on blood pressure (BP), and on LA and LV functions in hypertensive patients. Methods Thirty consecutive hypertensive patients who would undergo CR program, and 38 hypertensive patients who refused to undergo CR program were included. All patients underwent ambulatory BP monitoring and transthoracic echocardiography, which were repeated after completion of the CR program, or 12 weeks later in the control group. LA and LV functions were assessed by both speckle tracking and 3-dimensional echocardiography. N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were assessed before and after CR. Results Although initial ambulatory BP values and NT-proBNP levels were similar between the groups, daily, day-time, and night-time BP and NT-proBNP were significantly lower in the CR group after rehabilitation. LA reservoir strain and LV global longitudinal strain of the CR group significantly increased after CR while no significant increase was observed in controls. Conclusion CR improves LA and LV strain while lowering BP and should be encouraged in routine management of hypertensive patients.

PURPOSE Antiretroviral therapy (ART) has dramatically changed the clinical manifestation of human immunodeficiency virus (HIV) associated cardiomyopathy from severe left ventricular (LV) systolic dysfunction to a pattern of subclinical cardiac dysfunction. The aim of this study was to evaluate by speckle tracking echocardiography (STE) LV, right ventricular (RV), and biatrial functions in HIV-infected patients under different ART combinations. METHODS We consecutively included 128 HIV-infected patients (mean age 44.2 ± 10.1 years, 110 males) and 100 controls (mean age 42.1 ± 9.4 years, 83 males). Ventricular and atrial functions were assessed by both conventional and STE. RESULTS Although there was not any significant difference in conventional echocardiographic variables, HIV-infected patients had significantly lower LV global longitudinal strain (GLS), RV GLS, left atrial (LA) reservoir and conduit strain, and right atrial conduit strain. HIV patients receiving integrase strand transfer inhibitors and protease inhibitors (PI) had significantly lower LV GLS and LA conduit strain, while patients receiving non-nucleoside reverse transcriptase inhibitors and PI had significantly lower RV GLS than controls. CD4 count at the time of echocardiography was strongly correlated with LV GLS (r = .619, P

Acute heart failure (HF) is one of the most common cardiac emergencies. Pulmonary edema caused by HF may mimic an exudative disease on chest computed tomography scans. Coronavirus disease 2019 (COVID-19) emerged in China in December 2019 and quickly spread around the world. During this pandemic period, the need to exclude the possibility of COVID-19 pneumonia in patients with acute dyspnea may cause a delay in the diagnosis and treatment of patients with acutely decompensated HF who have similar symptoms. This case report describes a diabetic patient admitted with dyspnea one week after she suffered an acute myocardial infarction. The objective of this report is to draw attention to the differential diagnosis of HF and COVID-19 pneumonia.

A double-chambered right ventricle (DCRV) is a heart defect, typically congenital, in which the right ventricle is separated into a proximal high-pressure (anatomically lower) chamber and distal low-pressure (anatomically higher) chamber. Commonly ventricular septal defect is found concomitantly in patients with DRCV. In this case report, we present a 20-year- -old female patient who was found to have a DRCV without any concomitant congenital heart disorder.

Background and purpose Epilepsy is a disease known to occur with autonomous phenomenons. Earlier studies indicate decreased heart rate variability (HRV) during ictal and interictal periods among epilepsy patients. In this study, we aim to investigate cardiac rhythm abnormalities and HRV during interictal period between drug-naive patients with idiopathic generalized epilepsy (IGE) and healthy control group. Methods Twenty-six patients with IGE and 26 healthy individuals included in the study. In order to eliminate any structural cardiac pathology, transthoracic echocardiography was performed in all subjects and time and frequency domain parameters of HRV were evaluated after 24-hour rhythm holter monitoring. Results Between two groups, no significant difference was detected in terms of mean heart rate and maximum duration between the start of the Q waves and the end of the T waves (QT intervals). In the time domain analysis of HRV, no statically significant difference was detected for standard deviation of all R - R intervals and root-mean-square of successive differences between patient and control group (p = 0,070 and p = 0,104 respectively). In the frequency domain analysis of HRV, patients tended to display lower total power and very low frequency power than did healthy subjects, but the differences were not statistically significant. Conclusions Our results suggest that there is no major effect of the epilepsy on HRV in patients with IGE. It should be emphasized that, in this study, HRV was evaluated only in patients with IGE and that the results are not proper to be generalized for patients with partial seizures.

A prosthetic valve thrombosis (PVT), which is a potentially fatal complication, refers to the presence of non-infective thrombotic material on a prosthetic valve apparatus, interfering with its function. Possible complications of a PVT include transient neurologic embolic events, cardiac arrest due to a stuck valve prosthesis, and cardio-embolic myocardial infarction (MI). The choice of treatments, including a redo surgery, a percutaneous coronary intervention (PCI), and a fibrinolysis with PVT or MI dosages, depends on the patient's clinical and hemodynamic status and thrombotic burden involving the prosthetic valve and surrounding tissues. An early postoperative mechanical valve thrombosis is associated with increased risks due to the need for unforeseen early redo surgery complications and excessive bleeding risk in case of thrombolytic therapy usage. Here, we present a fifty-seven-year old female patient who was admitted to the emergency department with the complaint of acute chest pain seven days after an aortic prosthetic mechanical valve implantation. The clinical presentation was consistent with ST segment elevated MI and echocardiography revealed a large mass on the recently implanted prosthetic aortic valve. Valvular thrombotic complications after heart valve replacement operations are associated with high morbidity and mortality rates. Efficient and urgent treatment is necessary. Considering the clinical status of the patient, we preferred fibrinolytic therapy rather than PCI or surgery. The aim of this case report was to show the efficiency and safety of low-dose slow-infusion fibrinolytic therapy in PVT complicated with acute coronary syndrome.

Background Right ventricular (RV) involvement in inferior myocardial infarction (MI) increases in-hospital morbidity and mortality. Hypothesis RV systolic dysfunction assessed by 2-dimensional speckle tracking echocardiography (STE) might be a predictor of early mortality in patients with acute inferior MI. Methods Eighty-one consecutive patients with acute inferior MI (mean age, 60.8 ± 12.7 years; 18 females) were included. RV myocardial involvement was defined as an elevation >1 mm in V1 or V4 R within 12 hours of symptom onset. RV function was assessed by STE. Patients were followed for 30 days for all-cause mortality. Results Thirty-eight patients had RV myocardial involvement, and they had significantly lower tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (RVS), and left ventricular (LV) and RV global longitudinal strain (GLS). Nine patients (11%) died within 30 days. The mean age of mortality group was higher with more female frequency. They had significantly higher pro-BNP, hs-troponin T, and creatinine levels, but lower hemoglobin levels. TIMI 3 flow was significantly less achieved in mortality group. RV myocardial involvement was more frequent in the mortality group, and they had significantly lower TAPSE, RVS, and LV and RV GLS. Multivariate analysis revealed that age and RV GLS were independent predictors of early mortality. RV GLS ≤ -14% predicted early mortality in patients with acute inferior MI with a sensitivity of 88.9% and a specificity of 62.5% (AUC: 0.817, P = 0.002). Conclusions RV GLS may be useful in predicting early mortality in patients with acute inferior MI.

The aim of this study was to assess the right ventricular and right atrial functions in patients with nonischemic dilated cardiomyopathy by novel echocardiographic measures. In all, 40 patients with nonischemic dilated cardiomyopathy and 26 healthy subjects were consecutively included. Left ventricular, right ventricular, and right atrial functions were assessed by tissue Doppler imaging and two-dimensional speckle tracking echocardiography. Right ventricular systolic dysfunction was accepted moderated to severe when tissue Doppler peak systolic velocity of tricuspid lateral annulus was

Objective: The aim of the present study was to evaluate left atrial (LA) volume and functions using real-time three-dimensional echocardiography (RT3DE) and speckle tracking in systemic sclerosis (SSc) patients. Methods: The study was designed as a cross-sectional observational study. We studied 41 consecutive SSc patients (38 females, mean age: 49.5±11.6 years) and 38 healthy controls (35 females, mean age: 48.5±10.8 years). Patients with evidence or history of cardiovascular disease and patients with risk factors as hypertension, diabetes and chronic renal failure were excluded from the study. All study subjects underwent standard echocardiography; LA speckle tracking and RT3DE was performed to assess LA volume and phasic functions. Differences between numeric variables were tested using the independent sample Student’s t-test or Mann-Whitney U test, where appropriate. Results: There were no significant differences between SSC patients and controls regarding left ventricular (LV) systolic functions and two-dimensional (2-D) atrial diameters. Presence of LV diastolic dysfunction (LVDD) was evaluated and graded according to recommendations of the American Society of Echocardiography. Accordingly, LVDD was observed to be significantly more frequent in SSc patients; 16 SSc patients (39%) and 5 controls (12.8%) were observed to have LVDD (p=0.007). With regard to results obtained from RT3DE, LA maximum, minimum, and before atrial contraction volumes were significantly higher (40.5±14.6 vs. 32.6±8.9, 15.5±8.4 vs. 9.9±3.5 and 28.7±11.7 vs. 21.4±7.0 mL respectively, p

Although sleep deprivation (SD) affects cardiovascular system in many ways, physio-pathological changes in cardiac chamber volume and function have not been described well. The aim of the present study was to investigate the effect of SD on left atrial (LA) and ventricular function with three-dimensional (3D) echocardiography. Thirty-two healthy individuals (12 females, mean age 33.25 ± 8.18) were evaluated. Echocardiographic examination was performed once after a night of regular sleep and a night of sleep debt. Beside conventional parameters, 3D phasic volumes and function were measured using a commercially available 3D echocardiography system and offline analysis software. Mean sleep duration of the study group was 8.15 ± 2.19 h in the day of regular sleep and 2.56 ± 2.25 h in the day of sleep deprivation. There was a significant prolongation in deceleration time (180.83 ± 15.34 vs. 166.44 ± 26.12; p = 0.044) and increase in E/e’ (6.95 ± 1.26 vs. 6.38 ± 0.85; p = 0.005). Among 3D measurements, the difference in left ventricular ejection fraction (EF), LA EF, LA reservoir function and LA active EF were not significant. Mean LA passive EF of the individuals was significantly lower after night shift (24.10 ± 7.66 vs. 31.49 ± 7.75; p = 0.006). Acute SD is associated with a reduction in LA passive emptying function in healthy adults. 3D-derived indices were sufficient to show subclinical diastolic dysfunction according to impairment in passive phase of LA ejection. Prospective large-scale studies are needed to enlighten this issue.

Introduction: There is limited data in the literature regarding the association between hyperlipidemia and heart rate variability (HRV). The aim of the present study is to investigate the association between HRV and hyperlipidemia by retrospectively evaluating the recordings of subjects free of any apparent cardiovascular or systemic disease. Patients and Methods: Medical records of patients to whom 24 hour-Holter recording was performed in our clinic between January 2012 and May 2013 were retrospectively examined. Data of subjects who were determined to be free of any cardiovascular or systemic disease were used in the analysis. Results: Data of 37 subjects were used. There were 20 subjects with hyperlipidemia (10 male, age: 44.5 ± 11.1 years) and 17 subjects with normal lipid profile (5 male, age: 33.4 ± 10.6 years; p= 0.18 for gender and p=0.004 for age). Majority of HRV parameters were found to be significantly depressed in group with hyperlipidemia; however, there were no significant difference between groups regarding prevalence of arrhythmias. Out of components of the lipid profile, linear regression analysis revealed serum triglyceride level to be independently associated variable with RMSSD, PNN50 and LF/HF ratio (in respective order; beta= -0.40, p= 0.02; beta= -0.41, p= 0.012 and beta= -0.31, p= 0.05). Conclusion: Subjects with hyperlipidemia were observed to have significantly depressed HRV compared to subjects with normal lipid profile in our retrospective study. Based on our observations, it may be suggested that patients with hyperlipidemia, in particular with hypertriglyceridemia display higher subtle cardiac sympathetic activity which may be associated with increased cardiovascular morbidity and mortality.

Vitamin D deficiency is associated with impaired myocardial deformation parameters and cardiovascular disease (CVD). Increased epicardial fat thickness (EFT) is also associated with increased risk of CVD. The aim of the study is to evaluate the effect of vitamin D deficiency and supplementation on myocardial deformation parameters and EFT. The study population consisted of 50 patients with vitamin D deficiency who were free of cardiovascular risk (mean age: 42.6 ± 8.9 years, 37 female). Patients were treated with oral administration of vitamin D3. Myocardial deformation parameters and EFT were evaluated before and after treatment of those patients. Vitamin D levels significantly increased after treatment (30.5 ± 10.5 vs. 9.9 ± 5.3 nmol/l, p < 0.001). There was no significant difference between conventional echocardiographic parameters before and after treatment. Baseline EFT was significantly higher than post-treatment measurements (35.2 ± 8.0 vs. 27.5 ± 5.6 mm, p < 0.001). Post-treatment myocardial deformation parameters were also significantly higher than baseline measurements. Baseline vitamin D levels correlated with baseline EFT and left ventricular global longitudinal strain (LV-GLS). Post-treatment vitamin D levels also correlated with post-treatment EFT, body mass index, and LV-GLS. Baseline vitamin D level was an independent predictor of baseline LV-GLS (p = 0.002). Patients with impaired LV-GLS had significantly lower vitamin D levels than patients with normal LV-GLS (6.6 ± 3.8 vs. 11.0 ± 5.3 nmol/l, p = 0.005). Baseline vitamin D level was also an independent predictor of baseline impaired LV-GLS (p = 0.010). Vitamin D supplementation has beneficial effects on myocardial deformation parameters and EFT. Moreover, baseline vitamin D levels are a predictor of impaired LV-GLS.

Objective: The aim of this study is to compare the frequency of depression, anxiety, alexithymia and somatosensory sensitivity in patients with benign palpitation with healthy controls. Method: Sixty-one patients with palpitation and 59 age- and sex-matched control subjects were enrolled. All study subjects were undergone thorough cardiac evaluation, and patients with palpitation also had echocardiography and 24-hour ECG monitoring to rule out significant arrhythmias, coronary artery disease and structural heart disease. All subjects were assessed by Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Toronto Alexithymia scale, Whiteley Index (WI) and Somatosensory Amplification Scale (SAS). Results: Patients with benign palpitation had significantly increased BAI, BDI, WI and SAS scores. Anxiety is the only independent predictor of benign palpitation (odds ratio = 1.12, 95% confidence interval = 1.05–1.19, p

Sleep deprivation (SD) is known to be associated with increased incidence of adverse cardiovascular events, but underlying pathophysiological mechanism has not been clearly demonstrated. Autonomic nervous system plays an important role in the regulation of cardiovascular function, and impairment in this system is associated with increased cardiovascular mortality. The aim of the current study was to investigate the effect of acute SD on autonomic regulation of cardiac function by determining heart rate recovery (HRR).Twenty-one healthy security officers and nine nurses (mean age 33.25 ± 8.18) were evaluated. Treadmill exercise test was applied once after a night with regular sleep and once after a night shift in hospital. The HRR was calculated as the reduction in heart rate from peak exercise to the 30th second (HRR30), 1st minute (HRR1), 2nd minute (HRR2), 3rd minute (HRR3), and 5th minute (HRR5). The change in blood pressure (BP) measurements was also determined.Exercise capacity of individuals with SD was significantly lower (10.96 ± 1.01 vs. 11.71 ± 1.30 metabolic equivalent task (MET)s; p = 0.002), and peak systolic BP was significantly higher (173.8 ± 16.3 vs. 166.2 ± 9.9; p = 0.019). There was a signicant difference in HRR30 (12.74 ± 6.19 vs. 17.66 ± 5.46; p = 0.003) and HRR1 (31 ± 6.49 vs. 36.10 ± 7.78; p = 0.004). The ratio of these indices to peak HR was also significantly lower with SD (HRR%30 8.04 ± 4.26 vs. 10.19 ± 3.21; p = 0.025 and HRR%1: 18.66 ± 4.43 vs. 20.98 ± 4.72; p = 0.013). The difference in other indices of HRR was not significant.Our findings suggest that SD blunts cardiovascular autonomic response, and consequences of this relation might be more pronounced in subjects who are exposed to sleeplessness regularly or in subjects with baseline cardiovascular disease.

Published reports demonstrate improved myocardial reperfusion with adjunctive thrombus aspiration in ST-elevation myocardial infarction (STEMI). However, implementation of this procedure without angioplasty or stent implantation is not clear. In this report, we present an octogenarian with inferior STEMI who was treated with thrombus aspiration alone. Another important feature of our case is trapped thrombus material in the guiding catheter during thrombus aspiration. Operators should avoid thrombus re-injection by controlling the system carefully during aspiration procedure.

Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension.The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1 ± 10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3 ± 12.7 years) had non-dipper hypertension.Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3 ± 0.9 versus 1.8 ± 0.5, p 0.001). Patients with non-dipper hypertension had significantly higher PLR compared to dipper hypertension (117.7 ± 35.2 versus 100.9 ± 30.5, p = 0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22-7.13) and PLR more than 107 (odds ratio: 2.62, CI: 1.13-6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%.We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.

In this paper, we report an alternative approach for implantation of ventricular pacing lead for complete atrioventricular block after tricuspid valve replacement. doi: 10.1111/jocs.12288 (J Card Surg 2014;29:290–292)

Background/Aims: Atrial fibrillation (AF) is common among hemodialysis (HD) patients and is associated with high mortality. P wave dispersion (PWD) is a noninvasive electrocardiographic marker of paroxysmal AF. Our aim was to evaluate the effect of HD session on PWD. Methods: Twenty-five patients (mean age 63 years, 10 males) with sinus rhythm and undergoing chronic HD treatment were included. Blood samples were drawn and 12-lead electrocardiograms were recorded immediately before HD session, at the 2nd hour during HD and at the end of the HD session. The difference between maximum and minimum P wave durations was calculated as PWD. Results: PWD significantly increased during HD sessions compared with predialysis values (41 ± 12 vs. 21 ± 10 ms, respectively, p < 0.001), then decreased to a value of 24 ± 7 ms at the completion of HD, which was not significantly different from the predialysis values. PWD during HD was significantly correlated with predialysis systolic and diastolic blood pressure (r = 0.42, p = 0.037, and r = 0.59, p = 0.002, respectively) and predialysis serum potassium level (r = 0.44, p = 0.031). Linear regression model revealed that predialysis diastolic blood pressure (p = 0.002), predialysis serum potassium level (p = 0.037) and the amount of ultrafiltration (p = 0.048) were the significant predictors of prolonged PWD during HD. Conclusion: PWD increases significantly during HD sessions. This may increase the risk of AF episodes during HD. High diastolic blood pressure and serum potassium level before HD and ultrafiltration amount may predict prolonged PWD during HD.

Idiopathic hypereosinophilic syndrome is an uncommon leukoproliferative systemic disorder characterized by the overproduction of eosinophils and poor prognosis. A major source of morbidity and mortality of this syndrome is the associated cardiac involvement represented by endocardial thickening and mural thrombi. We report a 64-year-old woman with persistent symptoms of heart failure despite standard medical therapy. Echocardiography revealed reduced left ventricular filling due to a large apical mass; an abnormal diastolic filling pattern was also noticed. Complete blood count revealed remarkable hypereosinophilia. Cardiac magnetic resonance imaging demonstrated an apical thrombus and intense linear enhancement of the endocardium, which were compatible with Löffler endocarditis. Medical therapy, including corticosteroids and anticoagulation, was initiated promptly. The symptoms improved as the peripheral hypereosinophilia resolved in 15 days. The patient was asymptomatic at the 1-year follow-up visit with complete regression of the apical thrombus and no evidence of restrictive cardiomyopathy. We report this case to draw attention to this particularly rare condition with poor prognosis since quick and accurate diagnosis and prompt initiation of therapy may improve symptoms and survival.

The incidence of cardiac masses increased as echocardiography is becoming increasingly popular. Benign tumors of the heart constitute about 72% of all primary cardiac neoplasms and hemangioma accounts for 5-10% of benign cardiac tumors. Cardiac hemangiomas are generally asymptomatic and diagnosed incidentally during echocardiography or magnetic resonance imaging (MRI). We reported a 52-year-old woman presented with atypical chest pain and exertional dyspnea. The echocardiographic examination revealed a hyperechoic round mass in the left ventricle. With an initial diagnosis of left ventricular thrombus, the patient underwent cardiac MRI. The mass was found compatible with cardiac hemangioma. It was removed surgically and histopathologic evaluation identified a cardiac hemangioma. As reports of cardiac hemangioma are extremely rare and cardiac masses are mostly thought to be thrombi or myxomas (being the most common primary cardiac tumor), such hemangioma cases warrant attention as possibility of hemangioma should also be kept in mind.

Heart failure (HF) is the leading cause of in-hospital morbidity and mortality in the elderly population. Coexistence of HF and atrial fibrillation (AF) increases the risk of thromboembolic events. Oral anticoagulant therapy reduces the risk of thromboembolic events in patients with AF. Novel oral anticoagulants (NOACs) have been introduced as an alternative drug for prevention from thromboembolic events in patients with nonvalvular AF. The primary aim of this study is to investigate the clinical effects of warfarin, dabigatran, and rivaroxaban in patients with nonvalvular AF. The secondary aim of this study is to reveal the predictors of all-cause mortality in patients with nonvalvular AF undergoing NOACs therapy. The study population consisted of 171 patients with nonvalvular AF. Patients were divided into 3 groups according to the usage of oral anticoagulant therapy including coumadin (51 patients), dabigatran (52 patients), and rivaroxaban (68 patients). Although CHA2DS2-VASc score was similar between groups, HAS-BLED score was significantly higher in patients using rivaroxaban. Dyspepsia and itching were more common in patients using dabigatran. Heart failure and vascular disease were more common in the nonsurviving group (10 patients) than in the surviving group (110 patients) in patients using NOACs. Among age, sex, HF, hypertension, vascular disease, and CHA2DS2-VASc, which were included in the regression model, only the presence of HF was an independent predictor of all-cause mortality in patients using NOACs. In conclusion, the mortality rate is significantly higher in patients with HF using NOACs. Moreover, HF is an independent predictor of all-cause mortality in patients using NOACs.

Pulmonary embolism is a frequent and mortal situation especially in high-risk patients. Although thrombolytics and anticoagulants are the main options in treatment, substantial portion of patients also have high bleeding risk. Therefore, new catheter-directed treatment strategies, such as ultrasound-assisted transcatheter thrombolysis, gain importance in treatment options for intermediate and high-risk patients. Here, we report a case of massive pulmonary embolism due to the iatrogenic lymphocele after a radical retropubic prostatectomy procedure. The usage of ultrasound-assisted transcatheter thrombolysis was successful in such a high-risk patient.

Transcatheter aortic valve implantation (TAVI) has emerged as a therapeutic option for high-risk aortic stenosis. Malposition of the prosthesis and severe residual aortic regurgitation are known complications of the procedure, which might require a second valve implantation. Although the implantation of a second valve seems to be an effective method, very few data are available describing this technique. Herein is reported a case of iatrogenic chordal rupture in a TAVI procedure which required a second valve implantation due to dislodgment of the first prosthesis.

Objective: There is ongoing controversy related with relationship between biphosphonates and atrial fibrillation (AF). Our aim in this study was to evaluate the potential acute effect of zoledronic acid (ZA) infusion on AF development by using 24-hour Holter recording. Methods: Study was designed as to be a self-controlled case series study and 33 consecutive patients with osteoporosis (29 female, age: 62.3±9.0 years) who were scheduled to receive ZA infusion constituted study population. Patients underwent 24-hour Holter rhythm recordings at two different times; the first one, 48 hours before the planned ZA infusion and the second one, on the morning of the infusion day. Heart rate, frequency and type of arrhythmias as well as heart rate variability (HRV) from two recordings were compared. Results: There were no episodes of AF greater than 30 sec in any of 24-hour Holter recordings obtained before and on the day of drug infusion. Holter recordings before drug infusion showed that only 1 patient had an atrial run of 3 beats long. Holter recordings obtained on the day of drug infusion revealed that 5 patients (15.2%) had atrial runs with length ranging between 3 and 12 beats (p=0.046). Regarding HRV variables, SDANN values were found to be significantly depressed on the day of ZA infusion (113.6±26.9 vs. 98.2±29.9, p=0.007). Conclusion: None of the patients developed AF during or early after ZA infusion. However, there was an increase in atrial ectopy in some patients which might be due to alterations in cardiac autonomic activity. (Anadolu Kardiyol Derg 2014; 14(0): 000-000)

Left atrial (LA) volume has been identified as a predictor of adverse cardiovascular outcomes, both in the general population and in selected clinical conditions. The aim of this study was to evaluate the effect of psoriasis on LA volume and mechanical function. A total of 40 consecutive normotensive psoriasis patients free of any cardiovascular disease and 39 healthy volunteers were included. All participants underwent comprehensive transthoracic echocardiographic examination. LA volume and mechanical function were evaluated using real-time three-dimensional echocardiography (RT3DE). There were no significant differences between psoriasis and control groups with regard to conventional echocardiographic parameters. Individuals with psoriasis had a higher incidence of left ventricular diastolic dysfunction (LVDD) than the controls; nine people with psoriasis (23 %) and three control individuals (8 %) had LVDD (p = 0.06). With regard to the parameters obtained from RT3DE, LA maximum, LA minimum, passive stroke volume, and passive emptying fraction were significantly higher; whereas LA active emptying fraction, LA total emptying fraction, LA expansion index, and active stroke volume values were significantly lower in individuals with psoriasis compared with controls. Disease duration and Psoriasis Area of Severity Index (PASI) score correlated with the majority of volume parameters. Individuals with psoriasis had higher LA phasic volumes and impaired LA mechanical function compared with healthy controls. LA volume and functional analysis with RT3DE may facilitate recognition of subtle LA dysfunction in patients with psoriasis.

Objective: The aim of this study was to explore right ventricular (RV) mechanical function in patients with hypertrophic cardiomyopathy (HCM) by 2-D speckle tracking echocardiography (2-D-STE). Methods: Forty-three patients with HCM (mean age 48, 17 females) and 40 healthy subjects were consecutively included in this cross-sectional study. The diagnosis of HCM was based on the presence of typical clinical, electrocardiographic (ECG), and echocardiographic features. Patients with LV systolic impairment, significant valvular disease, history of coronary artery disease, hypertension, malignancy, and chronic obstructive pulmonary disease were excluded. Right and left ventricular (LV) function was assessed by tissue Doppler imaging (TDI) and 2-D-STE. Hypertrophic cardiomyopathy patients were divided into two groups according to ACC/ESC guidelines (LVOT gradient below and above 30 mm Hg). Student t-test was used to compare differences between groups. Non-parametric tests (Mann-Whitney U) were used in cases of abnormal distribution. Results: Hypertrophic cardiomyopathy patients had a significantly larger right atrium and RV diameters compared to controls. Mean pulmonary artery pressures (mPAB) were significantly higher in HCM patients (19.01 +/- 13.09 mm Hg vs. 8.40 +/- 4.50 mm Hg; p

Atrial fibrillation (AF) is an important risk factor for cardioembolic stroke. Warfarin is an effective treatment in reducing the risk of cardioembolic stroke in patients with AF. New anticoagulants have been widely using for stroke prophylaxis in patients with nonvalvular AF. Previous studies have suggested that thrombolytic therapy is effective treatment choice in patients with pulmonary embolisms. Warfarin therapy is also effective on prevention or treatment of cardiac thrombus in patients with AF. However, there are no evidence-based data on treatment of cardiac thrombus with new oral anticoagulants in patients with AF. In our case report, we reported an AF patient with cardiac thrombus and pulmonary embolism under dabigatran therapy.

Background The aim of the study was to explore the relation between regional myocardial dysfunction and fragmented QRS (fQRS) complexes in systemic sclerosis (SSc). Methods Fifty-three SSc patients and 26 controls were included. All subjects underwent speckle tracking echocardiography for evaluation of left ventricular (LV) function and ECG to check for fQRS complexes. Results SSc patients had significantly lower LV global longitudinal, radial and circumferential strain and twist compared to controls. Thirteen SSc patients had fQRS (DII, DIII, aVF leads in eleven patients and V1 to V5 leads in two patients) and they had significantly lower global longitudinal and circumferencial strain compared to SSc patients with normal QRS. The SSc patients with fQRS in DII, DIII, and aVF leads had impaired longitudinal strain and delay in time to peak longitudinal strain in inferior LV segments compared to those with normal QRS. Conclusion fQRS is associated with lower strain measures in SSc patients indicating impairment in LV function.

Determination of myocardial deformation (strain) by two-dimensional (2D) speckle tracking echocardiography (STE) is a new method for evaluating left ventricular (LV) regional function in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to assess LV and left atrial (LA) functions with 2DSTE in HCM patients and to investigate relation between strain analysis and LV outflow tract (LVOT) gradient.Forty consecutive HCM patients (26 male, mean age: 47.7 ± 15.2 years), and 40 healthy volunteers (22 male, mean age: 46.6 ± 11.2 years) were included in the study. All subjects underwent a transthoracic echocardiography for evaluation of LV and LA functions with 2DSTE. The HCM patients were divided into 2 groups according to the presence of resting LVOT gradient100 mmHg.Left ventricular global longitudinal strain (GLS), global radial strain (GRS), and global circumferential strain (GCS) were significantly lower in patients with HCM compared with controls (-20.3 ± 3.6% vs. -24.1 ± 3.4% P0.001, 38.1 ± 12.8% vs. 44.8 ± 10.2% P = 0.012, and -22.0 ± 4.4% vs. -23.9 ± 4.0% P = 0.045, respectively). Although basal and apical rotation were similar between the groups, mid-rotation was significantly clockwise in HCM patients (-1.53 ± 2.06° vs. 0.05 ± 1.7° P0.001). Both LA reservoir functions and LA conduit functions were significantly lower in HCM patients (21.6 ± 9.1% vs. 39.4 ± 10.6% P0.001, and 10.5 ± 4.3% vs. 15.7 ± 5.3%, P0.001). Fifteen patients had a resting LVOT gradient of100 mmHg and they had significantly decreased GLS, twist and untwist compared to the HCM patients with lower resting LVOT gradient (-18.7 ± 2.3% vs. -21.2 ± 3.9% P = 0.016, 19.4 ± 4.3° vs. 23.5 ± 7.4° P = 0.038 and -94.0 ± 29.1°/sec vs. -134.9 ± 55.8°/sec, 0.005, respectively). Although basal and apical rotation were similar between the 2 groups, mid-rotation was significantly clockwise in HCM patients with higher LVOT gradient (-2.52 ± 1.76° vs. -0.96 ± 2.03°, P = 0.018). Correlation analysis revealed that LVOT peak velocity was associated with GLS (r = -0.358, P = 0.023), LV mid-rotation (r = -0.366, P = 0.024), and LV untwist (r = -0.401, P = 0.013).Left ventricular and LA functions are impaired in patients with HCM. 2DSTE is useful in determining patients with impaired myocardial mechanics. High LVOT gradient may be one of the responsible factors that trigger deterioration of LV longitudinal strain and twist mechanics in patients with HCM. Further studies are required to clarify the preliminary results of this study.

BACKGROUND: Definite diagnosis of transudative or exudative pleural fluids often presents a diagnostic dilemma. The aim of this study was to evaluate whether amino-terminal brain natriuretic peptide (NT-proBNP) levels in pleural fluid has a diagnostic value for discriminating heart-failure-related pleural effusions from non-heart-failure effusions. METHODS: Sixty-six subjects (40 male, mean age 61 ± 18 y) with pleural effusions were included. Samples of pleural fluid and serum were obtained simultaneously from each subject. Biochemical analysis, bacterial and fungal culture, acid-fast bacilli smear and culture, and cytology were performed on the pleural fluid. RESULTS: Subjects with heart-failure-related pleural effusion had significantly higher pleural NT-proBNP levels than other subjects ( P < .001). Pleural and serum NT-proBNP measures were closely correlated (r = 0.90, P < .001). An NT-proBNP cutoff value of ≥ 2,300 pg/mL in pleural fluid had a sensitivity of 70.8%, a specificity of 97.6%, and positive and negative predictive values of 94.4% and 85.4%, respectively, for discriminating transudates caused by heart failure from exudates. Eight heart-failure subjects were misclassified as exudates by Light's criteria, 5 of whom received diuretics before thoracentesis. All misclassified subjects had pleural NT-proBNP levels higher than 1,165 pg/mL, which predicted heart-failure-associated transudates with 95.8% sensitivity and 85.7% specificity. CONCLUSIONS: Pleural fluid NT-proBNP measurement in the routine diagnostic panel may be useful in differentiation of heart-failure-related pleural effusions and exudative pleural fluids with reasonable accuracy, especially in heart-failure patients treated with diuretics.

A 51-year-old woman presented with severe chest pain minutes after starting intravenous paclitaxel as a part of the systemic chemotherapy due to ovarian carcinoma. The electrocardiogram (ECG) revealed sinus rhythm with ST-segment elevations in inferior and anterior leads. The ST-segment elevations resolved immediately after sublingual nitroglycerine. Cardiac troponin T and CPK MB levels remained in the normal range at repeat measurements. It was presumed that in spite of standard premedication, paclitaxel had induced acute coronary syndrome with ST-segment elevations in this patient. Copyright © 2009 Wiley Periodicals, Inc.

Introduction. Angiotensin-converting enzyme (ACE) inhibitors reduce cardiovascular events in patients with established vascular disease and heart failure (HF). ACE-inhibitors have important effects on fibrinolytic balance, which may be the underlying mechanism for a reduction in cardiovascular events.Although angiotensin-receptor blockers (ARBs) offer greater tolerability than ACE-inhibitors, the major ARB trials have demonstrated a lack of reduction in myocardial infarction (MI) occurrence and mortality in contrast to ACE-inhibitors. In this study, we investigated the combined effects of ARBs and ACE-inhibitors on fibrinolytic and inflammatory parameters in patients with uncontrolled hypertension. Methods. Twenty-four patients with uncontrolled hypertension despite taking adequate doses of ACE-inhibitor therapy were selected. Patients were started on Candesartan 16 mg once a day. Plasma plasminogen activator inhibitor (PAI-1) antigen (Ag), tissue plasminogen activator (t-PA) Ag, thrombin-activatable fibrinolysis inhibitor (TAFI) % activity and high sensitivity C-reactive protein (hsCRP) levels, were measured during low salt intake at baseline and two weeks after therapy with an ARB. Results. Addition of ARB to the regimen reduced systolic (155±17 R vs. 139±13, p Conclusions. Combined ARB and ACE-inhibitor use provide better BP control without any detrimental effect in plasma inflammatory and fibrinolytic parameters.

Background: Compared to atrioventricular sequential pacing, ventricular demand pacing is known to have somewhat more deleterious hemodynamic effects, which probably arise from increased sympathetic tonus and inappropriate baroreceptor activation. Endothelial function is affected by various local and systemic factors including baroreceptor activity. The aim of this study was to explore whether cardiac pacing would have any effect on endothelial functions. Methods: Twelve patients (six male, mean age: 75 ± 9 years) with previously implanted DDD or VDDcardiac pacemakers were included. All patients had stable atrial rhythms during the study. Patients were randomized to either atrial-based pacing mode (VDD or DDD) or ventricular demand pacing mode (VVI) first, and then cross-over was performed with the other pacing mode. Endothelial function was assessed by brachial artery ultrasonography. Basal diameter of the brachial artery, and both flow-mediated dilation (FMD) and endothelium-independent vasodilation with nitroglycerin were measured 1 hour after each pacing mode. Results: Compared to atrial-based pacing mode, ventricular demand pacing was associated with a significantly worse FMD both as absolute and percentage values (0.17 ± 0.09 mm vs 0.28 ± 0.11 mm, P = 0.015 and 4.84 ± 2.37 % vs 7.00 ± 2.88 %, P = 0.028, respectively). However, there was no significant difference in nitroglycerin-mediated vasodilation values between the two pacing sessions. Conclusions: Acute ventricular demand pacing (VVI pacing) is clearly associated with attenuation of FMD in patients with atrial-based pacing systems. The attenuation of endothelial vasodilation might have a role in hemodynamic and clinical deterioration in patients with VVI pacemakers.

Background Gonadotropin releasing hormone (GnRH) agonists are the cornerstone of metastatic prostate cancer treatment. Cardiovascular effects of GnRH agonists are unclear. In this study, we investigated the short term effects of GnRH agonists on plasma fibrinolytic parameters in patients with metastatic prostate cancer. Methods Eleven patients (mean age 69.3 ± 6.5) with metastatic prostate cancer and a clinical indication for GnRH agonist therapy were selected. Plasma plasminogen activator inhibitor (PAI-1) antigen (Ag), tissue plasminogen activator (t-PA) Ag and thrombin-activatable fibrinolysis inhibitor (TAFI) activity levels were measured at baseline and at 4 weeks after the first dose of GnRH agonist, Goserelin Acetate (Zoladex®, subcutaneous administration, 10.8 mg). Results Serum prostate specific antigen (PSA) levels significantly decreased from 36.6 ± 19.3 to 1.1 ± 0.3 ng/ml after Goserelin acetate treatment (P = 0.005). Significant changes occurred in the fibrinolytic parameters. GnRH agonists decreased plasma t-PA Ag levels (16.3 ± 4.9 vs. 12.2 ± 2.8 ng/ml, P = 0.047) and increased PAI-1/t-PA molar ratio (4.8 ± 3.6 vs. 6.6 ± 3.4, P = 0.16), on the other hand, plasma PAI-1 Ag (59.0 ± 48.5 vs. 56.4 ± 30.5 ng/ml, P = 0.8), and TAFI levels (130.6 ± 9.5 vs. 124.2 ± 26.5% activity, P = 0.3) did not change significantly. Conclusion This study provides evidence that GnRH agonists may inhibit fibrinolytic system by decreasing t-PA levels.
