Naples score is associated with SYNTAX Score in patients with ST-segment elevation myocardial infarction.

OBJECTIVE: The Naples Score (NS) predicts adverse outcomes in ST-elevation myocardial infarction (STEMI) patients, but the relationship between NS and the severity of coronary artery disease (CAD) in patients with STEMI has not been studied. In this study, we aimed to evaluate the role of NS at admission in predicting SYNTAX Score (SS). METHOD: We gathered the data from 499 consecutive STEMI patients who underwent percutaneous coronary intervention between January 2018 and September 2020. Patients were divided into two groups: low SS group (≤22) and intermediate to high SS group (>22). NS was calculated for both groups besides baseline clinical and demographic variables. RESULTS: NS was higher in the intermediate to high SS group and the SS was increasing as the NS escalates. In multivariate logistic regression analysis, the NS was an independent predictor of intermediate to high SS. Additionally, there was a positive correlation between SS and NS. CONCLUSION: Presentation NS predicts CAD complexity in patients with STEMI.

In-hospital outcomes of patients undergoing emergent surgical treatment in patients with infective endocarditis.

BACKGROUND: Infective endocarditis is a serious heart disease that may cause several different clinical conditions and can need urgent surgical therapy. In our study, we aimed to evaluate the patients with infective endocarditis undergoing acute surgical treatment results in-hospital mortality. METHODS: A total of 107 consecutive patients with infective endocarditis undergoing acute surgical therapy were included in our retrospective study. The patients were divided into two groups according to the presence of in-hospital mortality as Group 1 without in-hospital mortality (n=89) and Group 2 with in-hospital mortality (n=18). The demographic, laboratory, and clinical parameters were evaluated in both groups. RESULTS: The mean age (50±14; 64±14, P<0.001) and the incidence of chronic renal failure (9 [10.1%]; 8 [44.4%], P=0.001) were higher in Group 2 while the ejection fraction was lower in Group 2 (50.0±9.3; 44.6±12.9, P=0.039). The incidence of positive blood culture was also higher in Group 2 (41 [46.1]; 14 [77.8], P=0.014). Aortic bioprosthesis operation (2 [2.2]; 6 [33.3], P<0.001) and mitral bioprosthesis operation (4 [4.5]; 5 [27.8], P=0.008) were higher in Group 2 as well as the incidence of septic shock was also higher in Group 2 (1 [1.1]; 3 [16.7], P=0.015). In addition, in multivariate logistic regression analyses, advanced age (odds ratio [OR]: 1.068, 95% confidence interval [CI]: 1.009-1.130, P: 0.024) and positive blood culture (OR: 4.436, 95% CI: 1.044-18.848, P: 0.044) were found to be independent predictors of in-hospital mortality. CONCLUSION: Advanced age, lower ejection fraction, high creatinine, positive blood culture, high systolic pulmonary artery pressure, and septic shock predicted in-hospital death in patients who have undergone emergent or urgent surgery due to infective endocarditis.

Relationship between myocardial bridging and fatal ventricular arrhythmias in patients with hypertrophic cardiomyopathy: the HCM-MB study.

BACKGROUND: Myocardial bridging (MB) and hypertrophic cardiomyopathy (HCM) are associated with the risk of fatal ventricular arrhythmias (VAs). The goal of the study was to determine the relationship between MB and fatal VAs in HCM patients with implantable cardiac defibrillators (ICD). METHODS: A total of 108 HCM patients (mean age: 46.6 ± 13.6 years; male: 73) were enrolled in this retrospective study. All patients underwent transthoracic echocardiography and coronary computed tomography angiography. Fatal VAs including sustained ventricular tachycardia and ventricular fibrillation were documented in ICD records. RESULTS: There were documented fatal VAs in 29 (26.8%) patients during a mean follow-up time of 71.3 ± 30.9 months. Compared with the other groups, the fatal VA group had a higher incidence of the following: presence of MB (82.8 vs. 38%, p < 0.001), deep MB (62.1 vs. 6.3%, p < 0.001), very deep MB (24.1 vs. 0%, p < 0.001), long MB (65.5 vs. 11.4%, p < 0.001), presence of > 1 MB (17.2 vs. 0%, p = 0.001), and MB of the left anterior descending artery (79.3 vs. 17.7%, p < 0.001) . Sudden cardiac death (SCD) risk score (hazard ratio: 1.194; 95% CI: 1.071-1.330; p = 0.001) and presence of MB (hazard ratio: 3.815; 95% CI: 1.41-10.284; p = 0.008) were found to be independent predictors of fatal VAs in HCM patients. CONCLUSIONS: The current data suggest that the SCD risk score and presence of MB were independent risk factors for fatal VAs in patients with HCM. In addition to conventional risk factors, the coronary anatomical course can provide clinicians with valuable information when assessing the risk of fatal VAs in HCM patients.

Acute effects of inhaled iloprost on intracardiac conduction in patients with pulmonary arterial hypertension.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a severe, life-threatening disorder despite the availability of specific drug therapy. A lack of endogenous prostacyclin secondary to downregulation of prostacyclin synthase in PAH may contribute to vascular pathologies. Therefore, prostacyclin and its analogs including inhaled iloprost may decrease pulmonary arterial pressure and ventricular pressure. METHODS: Here, we studied that acute effects of iloprost used in pulmonary vasoreactivity testing on the intracardiac conduction system in patients with PAH. A total of 35 (15 idiopathic PAH, 20 congenital heart disease) patients with PAH were included in this prospective study. Patients were divided into two groups: 22 patients with negative pulmonary vasoreactivity in group 1 and 13 with positive pulmonary vasoreactivity in group 2. Electrophysiological parameters including basic cycle length, atrium-His (AH) interval, His-ventricle (HV) interval, PR interval, QT interval, QRS duration, Wenckebach period, and sinus node recovery time (SNRT) were evaluated before and after pulmonary vasoreactivity testing in both groups. RESULTS: The AH interval (81 [74-93]; 80 [65.5-88], p = 0.019) and SNRT (907.7 ± 263.4; 854.0 ± 288.04, p = 0.027) was significantly decreased after pulmonary vasoreactivity testing. Mean right atrium pressure was found to be correlated with baseline AH (r = 0.371, p = 0.031) and SNRT (r = 0.353, p = 0.037). CONCLUSION: Inhaled iloprost can improve cardiovascular performance in the presence of PAH, primarily through a reduction in right ventricular afterload and interventricular pressure. Decreased pressure on the interventricular septum and ventricles leads to conduction system normalization including of the AH interval and SNRT due to resolution of inflammation and edema.

Can local infiltration of lidocaine reduce the postoperative atrial fibrillation rate in patients undergoing lobectomy for lung cancer?

Background: Postoperative atrial fibrillation (POAF) occurs frequently after lung cancer surgery. Unfortunately, owing to the multifactorial etiology of POAF, no single drug or intervention can prevent POAF in all cases. The effects of local interventions after lung cancer surgery are unknown. This study investigated the effects of local infiltration of an anesthetic (lidocaine) on the post-lobectomy POAF rate.Methods: This non-randomized study included 81 patients who underwent lobectomy for lung cancer. Patients were divided into a lidocaine-infiltration group comprising patients who received lidocaine infiltration around the pulmonary veins and a no-intervention group. Patients were monitored for the development of POAF during hospitalization. Pre- and postoperative demographic and clinical data were analyzed.Results: AF occurred in 3 (7.5%) of 40 patients in the lidocaine-infiltration group and in 10 (24.39%) of 41 patients in the standard surgical resection group. Overall, it was observed that intraoperative lidocaine infiltration resulted in a lower POAF rate (p < .05).Conclusion: Local infiltration of lidocaine around the pulmonary veins in patients undergoing lobectomy for lung cancer was associated with a lower incidence of POAF, which is attributable to the local anesthetic and autonomic effects of lidocaine.

The diagnostic value of serum copeptin levels in an acute pulmonary embolism.

BACKGROUND: Acute pulmonary embolism (APE) is a common disease which is associated with high mortality and morbidity. Circulating level of copeptin, which was demonstrated to be elevated in heart failure, acute myocardial infarction and pulmonary arterial hypertension, were reported to be independent predictors of poor outcome in recent studies. The aim of the present study was to investigate the clinical utility of copeptin in the diagnosis of APE. METHODS: A total of 90 consecutive patients, admitted to emergency service due to acute chest pain and/or dyspnea and who underwent pulmonary computerized tomography angiography (CTA) due to suspicion of APE, were included in this prospective study. The patients diagnosed with APE were defined as APE (+) group and the remaining individuals with normal pulmonary CTA result were defined as APE (-) group. RESULTS: Copeptin levels (7.76 ± 4.4 vs. 3.81 ± 1.34 ng/dL; p < 0.001) were higher in the APE (+) group as compared to the APE (-) group. Copeptin was significantly positively correlated with B-type natriuretic peptide (r = 0.434, p < 0.001), D-dimer (r = 0.315, p = 0.003) and troponin I (r = 0.300, p = 0.004) and inversely correlated with arterial oxygen saturations (r = -0.533, p < 0001). When the correlation of copeptin with right ventricular dysfunction parameters was investigated, it was significantly inversely correlated with the tricuspid annular plane systolic excursion (r = -0.521, p < 0.001) and positively correlated with right to left ventricle ratio (r = 0.329, p = 0.024). Copeptin (OR 1.836, 95% CI 1.171-2.878, p = 0.008) was found as a significant independent predictor of APE in a multivariate analysis, after adjusting for other risk parameters. CONCLUSIONS: Copeptin is a promising new biomarker, which may be used to support the need for further investigations and to improve the diagnosis of patients with APE.

Exclusion of a Huge Left Ventricular Outflow Tract Pseudoaneurysm with Konno's Procedure.

We present the use of Konno's procedure for the reconstruction of a huge left ventricular outflow tract pseudoaneurysm formed after aortic valve replacement.

Fragmented QRS complexes are associated with left ventricular systolic and diastolic dysfunctions in patients with metabolic syndrome.

BACKGROUND: Metabolic syndrome (MetS) is found to be associated with deterioration of the left ventricular (LV) systolic and diastolic functions. One of the factors for this impairment is myocardial fibrosis. Fragmented QRS (fQRS) complexes are found to be associated with myocardial fibrosis. The aim of the study was to evaluate if the presence of fQRS on electrocardiogram (ECG) can detect pronounced impairment in the LV systolic and diastolic functions in MetS patients. METHODS: The study included 111 (mean age 47 ± 9, 49.5% male) MetS patients and 96 (mean age 45 ± 9, 58.3% male) control subjects without MetS. ECG was evaluated for the presence of fQRS. Each patient underwent conventional echocardiography and tissue Doppler imaging. RESULTS: Fragmented QRS was more common among MetS patients (26.1% vs. 14.6%, p = 0.041). MetS was associated with subclinical LV systolic and LV diastolic dysfunctions. In subgroup analyses of MetS patients, the presence of fQRS on ECG had a higher E/E' ratio and lower E' velocity, indicating pronounced diastolic dysfunction, as well as lower isovolumic acceleration(IVA), indicating profound subclinical LV systolic dysfunction. E/E' ratio and IVA were independent predictors of fQRS presence in patients with MetS. CONCLUSIONS: Fragmented QRS is more common among MetS patients compared to non-MetS patients. The presence of fQRS is associated with pronounced subclinical LV systolic and diastolic dysfunctions in MetS patients.

Immunosuppressive therapy induced coronary vasospasm and acute myocardial infarction in a patient undergoing new renal transplantation.

Immunosuppressant agents such as calcineurin inhibitors (CNI) used after solid organ transplantation may cause endothelial dysfunction, and coronary and renal arterial vasospasm. We report a patient presenting acute ST segment elevation myocardial infarction (STEMI) at the second week of renal transplantation. In the case of STEMI in patients with solid organ transplants under immunosuppressive therapy with CNI, coronary vasospasm associated with these drugs should be kept in mind before starting any interventional procedure. High dose nitroglycerine may immediately resolve tacrolimus or cyclosporine A induced coronary vasospasm. Calcium channel blockers should immediately be added to treatment because of the short half-life of nitroglycerine.

Posttraumatic infrarenal abdominal aortic pseudoaneurysm treated with bifurcated endovascular graft stent.

Posttraumatic infrarenal aortic pseudoaneurysms are rare and potentially lethal lesions. We report the case of a 32-year-old man presenting with infrarenal aortic pseudoaneurysm eight months after being stabbed in the back and right flank. His pseudoaneurysm was close to the iliac bifurcation, so we decided to deploy a bifurcated endovascular graft stent, the TriVascular Ovation endovascular stent. Imaging one month after the procedure revealed no endoleak and slight shrinkage of the pseudoaneurysm.

Serum copeptin levels in predicting nondippers in newly diagnosed hypertension.

OBJECTIVES: The nondipper pattern in hypertension is associated with worse cardiovascular outcomes. In this study, we hypothesized that high copeptin levels could predict nondippers among hypertensive patients and investigated the associations between copeptin levels and nondipper pattern in newly diagnosed hypertensive patients. METHODS: Ambulatory blood pressure measurements were obtained and the patients were divided into two groups according to ambulatory blood pressure measurement as nondippers and dippers. Serum copeptin levels were measured in addition to routine laboratory investigations. A total of 76 patients were included in the study. RESULTS: The clinical and laboratory characteristics of the two groups were similar. The mean copeptin values were found to be significantly higher in the nondipper hypertensive group [1.66 (1.19-4.01) and 1.35 (1.12-2.09) IU/ml, respectively, P=0.026]. In the correlation analysis, no correlation was found between copeptin levels and daytime diastolic blood pressure, but there were weak positive correlations with daytime systolic, 24 h systolic, and diastolic blood pressure values (r=0.335, P=0.034, r=0.350, P=0.027, r=0.372, P=0.018, respectively). However, there were significant positive correlations between serum copeptin levels and nocturnal systolic and diastolic blood pressure values (r=0.593, P<0.001, r=0.523, P=0.001, respectively). CONCLUSION: This study showed that high serum copeptin levels could predict the nondipper pattern in newly diagnosed hypertension.

Antiplatelet resistance and the role of associated variables in stable patients treated with stenting.

INTRODUCTION: Nowadays, clopidogrel and acetylsalicylic acid (ASA) have become routinely applied therapies in percutaneous coronary interventions (PCI) with stenting. AIM: Numerous variables can interfere with antiplatelet responsiveness, so we aimed to investigate the role of different variables associated with ASA or clopidogrel resistance in stable coronary artery disease. MATERIAL AND METHODS: A total of 207 patients undergoing elective PCI were included in the analysis. All patients received a loading dose of clopidogrel and ASA during PCI procedure and followed by dual antiplatelet therapy. Clopidogrel and ASA resistance were measured by impedance aggregometry method. RESULTS: Of the patients, 19.8% had clopidogrel resistance, 18.8% had ASA resistance, 9.2% had both clopidogrel and ASA resistance, and 71.5% were responsive to both drugs. In multivariate analysis, platelet count, angiotensin receptor blocker (ARB) use, and ASA resistance were independent variables associated with clopidogrel resistance, and clopidogrel resistance was the only variable associated with ASA resistance. In differentiating whether clopidogrel resistance exists or not, optimum ASA aggregometry response cut-off values were specified, and in differentiating whether ASA resistance exists or not, optimum clopidogrel aggregometry response cut-off values were specified. CONCLUSIONS: In this study, there was a higher incidence of low responsiveness to ASA when there was a low response to clopidogrel, and vice versa. Angiotensin receptor blocker use, platelet count, and ASA resistance were independent variables associated with clopidogrel resistance. Clopidogrel resistance was the only independent variable associated with ASA resistance. Angiotensin receptor blocker use seems to an independent risk factor for clopidogrel resistance in this study, but this result needs to be verified in other studies.

The role of isovolumic acceleration in predicting subclinical right and left ventricular systolic dysfunction in patient with metabolic syndrome.

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<0.001 and 2.6±0.7 vs. 3.1±0.9, p=0.001, respectively). Whereas, TDI derived systolic velocity (Sa), and peak myocardial velocity during isovolumic contraction (IVV) of both ventricles were similar between the two groups. In the multiple regression analysis, waist circumference and diastolic blood pressure were found to be an independent determinant of IVA of LV (b=-.223, 95% CI=-.034 -.002, p=0.004) and RV (b=-.527, 95% CI=-.085 -.020, p=0.002) respectively. CONCLUSION: MetS affects global, diastolic, and systolic functions of two ventricles. This disruption lead to decreased function of heart was related with raised risk factors of MetS.

Is there a correlation between coronary artery ectasia and neutrophil-lymphocyte ratio?

We aimed to investigate the association between the neutrophil-lymphocyte ratio (NLR) and coronary artery ectasia (CAE). The study included 198 patients who had undergone coronary angiography for suspected coronary artery disease (CAD). The patients were divided into the following 4 groups: group 1, 44 patients with normal coronary arteries; group 2, 61 patients with CAD; group 3, 40 patients with isolated CAE; and group 4, 53 patients with CAE coexisting with CAD. Neutrophil-lymphocyte ratio was significantly lower in group 1 than the other groups and significantly higher in group 4. Patients in group 1 had significantly lower neutrophil counts and significantly higher lymphocyte counts than the patients in group 4. The isolated CAE and CAD groups were similar in terms of NLR, neutrophil count, and lymphocyte count. In addition, we found significant positive correlations between presence of ectasia, number of ectatic vessels, and NLR. Our findings provide additional evidence for the role of NLR in CAE.

Aspirin resistance in patients undergoing hemodialysis and effect of hemodialysis on aspirin resistance.

The aim of this study was to evaluate the prevalence of aspirin resistance (AR) in patients undergoing hemodialysis (HD) and to assess the effect of HD on the results of the Multiplate test. A total of 54 patients undergoing HD were included in this study. Blood samples were taken just before and after the HD session. To determine AR, we used Multiplate test. Platelet aggregation values of the study population were 363.01 ± 225.69 aggregation unit (AU) × minutes before and 375.33 ± 254.05 AU × minutes after the HD (P = .597). There was strong correlation between the values before and after HD (R = .755, P < .0001). The AR status was changed in 9 (16.6%) patients after HD. Agreement of AR status before and after HD was substantial (κ coefficient = .667, P < .0001). The prevalence of AR in patients undergoing HD seems higher than in most of the studied populations, and this study has shown that the AR statuses of a significant number of patients undergoing HD change after an HD session.

Assessment of sustained effects of levosimendan and dobutamine on left ventricular systolic functions by using novel tissue Doppler derived indices in patients with advanced heart failure.

BACKGROUND: Previous studies comparing levosimendan vs. dobutamine have revealed that levosimendan is better in relieving symptoms. Echocardiographic studies have been done using second measurements immediately following a dobutamine infusion or while it was still being administered. The aim of our study was assessment of sustained effects of 24 h levosimendan and dobutamine infusions on left ventricular systolic functions. METHODS: A total of 61 patients with acutely decompensated heart failure with New York Heart Association (NYHA) class III or IV symptoms were randomized to receive either levosimendan or dobutamine 2:1 in an open label fashion. Before and 5 days after the initiation of infusions, functional class was assessed, N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) levels and left ventricular ejection fraction (LVEF), mitral inflow peak E and A wave velocity, and E/A ratios were measured; using tissue Doppler imaging, isovolumic myocardial acceleration (IVA), peak myocardial velocity during isovolumic contraction (IVV), peak systolic velocity during ejection period (Sa), early (E') and late (A') diastolic velocities, and E'/A' and E/E' ratios were measured. RESULTS: The NYHA class improved in both groups, but improvements were prominent in the levosimendan group. NT-proBNP levels were significantly reduced in the levosimendan group. Improvements in LVEF and diastolic indices were significant in the levosimendan group. Tissue Doppler-derived systolic indices of IVV and IVA increased significantly in the levosimendan group. CONCLUSIONS: Improvements in left ventricular systolic and diastolic functions continue after a levosimendan infusion.

A comparative analysis of leukocyte and leukocyte subtype counts among isolated systolic hypertensive, systo-diastolic hypertensive, and non-hypertensive patients.

BACKGROUND: Isolated systolic hypertension (ISHT) is a subtype of hypertension (HT) that often exhibits wide pulse pressure, and pulse pressure has a strong predictive value for future adverse cardiovascular events. Previous studies have shown the effects of leukocyte count on the prognosis of ischaemic heart disease and HT. AIM: Thus, in this cross-sectional study, we analysed the relationship between leukocyte counts and subtypes in HT and non-HT groups. METHODS: The study population consisted of 960 consecutive patients who were admitted to the outpatient clinic of our hospital. After ambulatory blood pressure values were assessed, the participants were divided into three groups: ISHT (n = 98), systo-diastolic hypertensives (SDHT, n = 405), and non-hypertensives (non-HT, n = 457). RESULTS: The subjects in the ISHT group were older than those in the SDHT and non-HT groups (64 ± 10, 53 ± 12, and 52 ± 13, respectively; p < 0.001). The leukocyte and neutrophil counts and neutrophil/lymphocyte (NL) ratios were significantly different in all groups. In subgroup analysis, the leukocyte count, neutrophil count, and N/L ratio were higher in the ISHT and SDHT groups than in the non-HT group (p < 0.001 for all). The leukocyte count, neutrophil count, and N/L ratio were significantly higher in the ISHT group than in the SDHT group (p = 0.023, p = 0.007, p = 0.010, respectively). Neutrophil count (p = 0.012; OR = 1.229, 95% CI 1.046-1.444) was an independent risk factor for ISHT in multivariate logistic regression analysis. CONCLUSIONS: The leukocyte and neutrophil counts and N/L ratios were higher in the ISHT group than in the SDHT and non-HT groups. High neutrophil count was an independent predictor of ISHT.

Aspirin resistance in patients with impaired renal functions.

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of death in patients with chronic kidney diseases (CKD). Aspirin resistance (AR) worsens prognosis in CVD. AIM: The aim of this study was to detect AR prevalence in this patient group. METHODS: The 203 patients (mean age 61.84 ± 11.51 years, 128 [63.1%] male) with stable coronary artery disease included in the study were grouped into four study groups according to their estimated glomerular filtration rate (eGFR) values. Multiplate test was used to determine AR. Platelet aggregation results were presented as aggregation unit (AU) × min and values over 300 AU × min were accepted as AR. RESULTS: 61 (30.04%) patients in the whole study population were found to have AR. Differences were detected between AR ratios and multiplate values of the patient groups (p = 0.006 and p = 0.002). AR ratio was highest in patient group 4 (eGFR < 30 mL/min/1.73 m²) and/or on chronic haemodialysis therapy, whereas there was little difference among the other three groups. In multivariate analysis, while AR status was independently related to female sex (OR = 2.31,CI 1.14-4.65, p = 0.019) and mean platelet volume (MPV) (OR = 1.68, CI 1.21-2.33, p = 0.002), multiplate test results were independently related to MPV (b = 0.265, p < 0.0001) and eGFR (b = -0.165, p = 0.025). CONCLUSIONS: The AR ratio was found to be high in severe CKD patients, especially haemodialysis patients, but not in mild and moderate CKD patients. This increased AR ratio in severe CKD patients may affect the prognosis in patients who already have an increased risk for cardiovascular complications.

Impact of levosimendan on right ventricular functions by using novel tissue Doppler derived indices in patients with ischaemic left ventricular failure.

BACKGROUND: Right ventricular (RV) dysfunction complicates advanced left ventricular (LV) heart failure (HF) and contributes to a poor prognosis. Levosimendan is a positive inotropic agent improving cardiac contractility without increasing myocardial oxygen consumption in HF. AIM: To evaluate the effect of levosimendan therapy on RV systolic function, by using derived tissue Doppler imaging (TDI) in patients with ischaemic HF. METHODS: The study consisted of 30 patients with HF who were admitted to our hospital due to new onset of decompensated HF, having LV ejection fraction < 40%, with functional status class III-IV, according to the New York Heart Association (NYHA). TDI-derived systolic velocities of tricuspid annulus (isovolumic myocardial acceleration [IVA], peak myocardial velocity during isovolumic contraction [IVV], peak systolic velocity during ejection period [Sa]) and diastolic indices (early [Ea] and late diastolic [Aa] velocities, Ea/Aa, E/Ea ratios and myocardial performance index [Tei index]) were measured. 72 hours after treatment, all measurements were re-evaluated. RESULTS: Considering TDI-derived systolic indices of the RV, IVA and IVV increased significantly, whereas Tei index decreased, after the therapy. Also, there was a significant decrease in serum levels of B-type natriuretic peptide. No significant change was observed in TDI derived diastolic indices of the RV. CONCLUSIONS: Levosimendan improves RV systolic function as expressed by TDI-derived parameters in patients with acutedecompensated HF.

Vascular endothelial function assessed by a noninvasive ultrasound method and serum asymmetric dimethylarginine concentrations in mild-to-moderate plaque-type psoriatic patients.

OBJECTIVES: Our aim was to evaluate vascular endothelial function assessed by serum asymmetric dimethylarginine (ADMA) concentrations and noninvasive ultrasonographic parameters such as flow-mediated dilatation (FMD) and nitroglycerin-induced dilatation (NID) in mild-to-moderate plaque-type psoriatic patients, as rated by the Psoriasis Area and Severity Index. DESIGN AND METHODS: Plaque-type psoriatic patients (n = 29) diagnosed with clinical and/or histopathological findings and control subjects (n = 25) without skin and systemic metabolic diseases were included in the study. RESULTS: There was no statistically significant difference between patients and control subjects in respect to FMD (p = 0.441), NID (p = 0.557), or serum ADMA concentrations (p = 0.225). Also, among the acute-phase reactants, serum C-reactive protein and plasma fibrinogen levels were moderately higher in patients when compared to control subjects (p = 0.008 and p = 0.011, respectively). CONCLUSIONS: Mild-to-moderate plaque-type psoriatic patients with low-to-medium grade systemic inflammation did not have evidence of vascular endothelial function.
