The relationship of platelet-to-lymphocyte ratio with clinical outcome and final infarct core in acute ischemic stroke patients who have undergone endovascular therapy.

OBJECTIVES: Of all strokes, 85% are ischemic and intracranial artery occlusion accounts for 80% of these ischemic strokes. Endovascular therapy for acute ischemic stroke was a new modality aiming at resolution of clots in occluded cerebral arteries. The platelet-to-lymphocyte ratio (PLR) was introduced as a potential marker to determine increased inflammation, which is a result of releasing many mediators from the platelets. In this study we aimed to evaluate whether the PLR had a prognostic role in stroke patients undergoing thrombectomy and attempted to determine the effect that this ratio had on their survival. METHODS: Over a three-year period, demographic, clinical, and angiographic findings of 57 consecutive patients with acute ischemic stroke who underwent mechanical thrombectomy were evaluated. RESULTS: The patients were divided into two groups on the basis of a PLR level cut-off value of 145 based on receiver operating characteristic (ROC) curve. Successful revascularization (mTICI 2b and 3) was achieved in 42 of 57 (73.7%) patients; a mTICI 3 state was observed in 21 of 23 patients with low-PLR values (p = .015). Patients with higher PLR values had significantly a score of less than six on the ASPECT scale compared to patients with lower PLR values (p = .005). The patients with low-PLR values had better functional outcomes (mRS ≤ 2) compared with the patients with high-PLR values [respectively, p = .004 (at first month) and p = .014 (at third month)]. DISCUSSION: The platelet-to-lymphocyte ratio could represent pro-thrombotic inflammatory state in acute ischemic stroke patients because having a high-PLR values increased the poor prognosis, the rate of insufficient recanalization, and the size of infarcted area.

Association of platelet-to-lymphocyte ratio with silent brain infarcts in patients with paroxysmal atrial fibrillation.

OBJECTIVES: In this study, we aimed to evaluate whether the inflammation as measured by increased platelet to lymphocyte ratio (PLR) predispose to silent infarcts in patients with paroxysmal atrial fibrillation (PAF). METHODS: The present study investigated a total of 48 new diagnosed patients with PAF who had no signs of stroke. PLR, which was calculated as the ratio of the platelet count to the lymphocyte count, C-reactive protein and erythrocyte sedimentation rate were measured due to evaluate inflammatory state. Magnetic resonance imaging (MRI) was performed to evaluate the presence of silent brain infarcts (SBIs) in patients. We calculated CHA2DS2-VASc scores for stratifying the stroke risk of patients. RESULTS: Among our study population, the mean age was 56.40 ± 8.99; 36 patients were female. The leading vascular risk factor was hypertension (45.8%). SBI was determined in 16 patients (33.3%) on MRI. It was found that a higher PLR is significantly associated with the presence of SBIs in patients with PAF (P = .001). High PLR group showed silent lesions predominantly multiple, greater than 5 mm, bilateral and in the subcortical region; though no statistically significant differences were found in each lesion areas (P = .214; P = .509; P = .746; P = .059, respectively). Of 16 patients who showed SBI, 1 (6.3%) patient had CHA2DS2-Vasc scores of 0; 7 (43.8%) patients had CHA2DS2-Vasc scores of 1; 6 (37.5%) patients had CHA2DS2 -Vasc scores of 2 and 2 (12.5%) patients had CHA2DS2-Vasc scores of 3. We did not find any significant relationship between CHA2DS2-Vasc scores and presence of SBI in the study patients (P = .850). DISCUSSION: High PLR might be a factor to induce inflammatory process on SBIs even with low CHA2DS2-VASc scores.

Early experience of percutaneous paravalvular leak closure using a novel Occlutech occluder.

AIMS: Paravalvular regurgitation is an important complication of mitral valve replacement. Although surgical repair is mostly recommended, it is associated with significant morbidity. On the other hand, percutaneous closure is a less invasive alternative approach. Percutaneous approaches to treatment of paravalvular prosthetic regurgitation have emerged recently. One of them is the Occlutech Paravalvular Leak Device. The aim of this study was to evaluate early and midterm outcomes of percutaneous paravalvular leak closure utilising a novel occluder. METHODS AND RESULTS: Twenty-one consecutive symptomatic patients who had moderate or severe paravalvular prosthetic regurgitation on transoesophageal echocardiography were included in the study. All the patients were clinically evaluated and found inoperable for surgery. They underwent transapical repair with the Occlutech Paravalvular Leak Device. The patients were followed for 17±5 months. Attempts were made to rectify 41 defects in 21 patients with 100% success. Mean procedure time was 76±40 min and fluoro-scopy time was 44±37 min. Early post-procedural outcome was uneventful in all cases, with ≥1 grade reduction in regurgitation in all of the patients. There was no mortality during hospital stay. There was one case of haemothorax in one patient and one case of pneumothorax in another. Post-implantation 90-day follow-up data were obtained for 19 patients, and 12-month data were obtained for 12 patients. No deaths due to any cause, stroke or surgery for prosthetic impingement, worsening or relapse of paravalvular leak during follow-up were recorded. One patient underwent reintervention and was treated successfully with the same occluder 11 months after the index procedure. CONCLUSIONS: The novel Occlutech Paravalvular Leak Device, which was designed specifically for mitral and aortic paravalvular regurgitation, is an additional, useful tool in the device armamentarium for the treatment of PVL.

Is there any link between joint hypermobility and mitral valve prolapse in patients with fibromyalgia syndrome?

The objective of the present study is to determine whether benign joint hypermobility syndrome (BJHS) modifies the risk of mitral valve prolapse (MVP) in patients with fibromyalgia (FM). Female patients fulfilling the 1990 American College of Rheumatology (ACR) diagnostic criteria for FM were included into the study. Joint hypermobility and BJHS were assessed using Beighton's scoring system and Brighton criteria, respectively. Echocardiograpic evaluation was performed in order to test the presence of MVP. Of the 75 female FM patients, 68.0 % (n = 51) and 20.0 % (n = 15) were diagnosed with BJHS and MVP, respectively. The frequencies of both MVP and BJHS seemed higher than the general population prevalence (p = 0.000 for both). The frequency of MVP was significantly higher in patients with BJHS than that in patients without BJHS (p = 0.028). In addition, BJHS was found to increase the risk of MVP approximately ninefold [odds ratio (OR) 8.7, 95 % confidence interval (CI) 1.1-70.7]. As a result, BJHS and MVP are both common in female patients with FM. Moreover, among the female patients with FM, those with BJHS are about nine times more prone to MVP than those without BJHS. Cardiologic assessment might be added to the routine follow-up strategies in FM patients with BJHS in order to exclude the cardiac pathologies, especially MVP.

Atrial conduction abnormalities in patients with psoriasis vulgaris.

BACKGROUND: Psoriasis vulgaris is one of the most common chronic inflammatory skin disorders. Patients with psoriasis are at risk of developing atrial fibrillation (AF). The electromechanical delay (EMD) is the time interval from the onset of the P wave on surface electrocardiography (ECG) to the beginning of the A wave. Prolonged atrial EMD is an independent risk factor for the development of AF. AIM: This study investigated the intra- and interatrial EMD in patients with psoriasis. METHODS: This study included 85 adults with psoriasis vulgaris (Group 1) and 46 age- and sex-matched healthy individuals (Group 2). ECGs were obtained from all subjects, and atrial EMD variables were calculated. Results are reported as means ± standard deviations and percentages. Continuous variables were analysed using Student's t-test. A p-value < 0.05 was considered statistically significant. RESULTS: Interatrial electromechanical delay (IA-EMD) and intra-left atrial electromechanical delay (ILA-EMD) were significantly longer in the psoriasis group compared with controls. A correlation analysis between psoriasis severity (PASI score) and the atrial conduction parameters revealed a significant positive correlation between PASI and IA-EMD (r = 0.261, p < 0.001). In addition, there was a positive correlation between high-sensitivity C-reactive protein (hsCRP) and IA-EMD (p = 0.022). CONCLUSIONS: The atrial conduction time was longer in patients with psoriasis vulgaris and it correlated with the severity of disease and hsCRP. Since the association between delayed conduction and AF is known, the measurement of intra-atrial conduction times could be a practical tool to estimate the AF risk in these patients.

Endovascular therapy of acute ischaemic stroke by interventional cardiologists: single-centre experience from Turkey.

AIMS: We report our single-centre experience with the Solitaire AB self-expanding retrievable stent system in patients with acute ischaemic stroke. METHODS AND RESULTS: Demographic, clinical, and angiographic findings of thirty-eight consecutive patients with acute ischaemic stroke who underwent mechanical thrombectomy were evaluated retrospectively. The mean initial National Institutes of Health Stroke Scale (NIHSS) score was 17.8±4.6. Nearly half of the patients had a middle cerebral artery (MCA) occlusion (45%). Both internal carotid artery and MCA occlusions were detected in five patients. Successful revascularisation (Thrombolysis in Cerebral Infarction [TICI] 2b and 3) was achieved in 34 of 38 (89%) patients; a TICI 3 state was observed in 24 (63%) patients. Almost three quarters of the patients (74.3%) improved by >5 points on the NIHSS at discharge, and 57.9% showed a modified Rankin Scale (mRS) score of ≤2 at 90 days. CONCLUSIONS: This single-centre experience with mechanical thrombectomy devices demonstrated that the procedure could be performed safely with high success rates by experienced interventional cardiologists in suitably equipped cathlabs.

Successful transcatheter closure of bilateral multiple coronary arterial fistulae in one session.

Coronary artery fistulae represent the most frequent congenital anomalies of the coronary arteries, but multiple bilateral fistulae are a rare condition. Current therapeutic options for symptomatic patients are percutaneous closure and cardiac surgery. Transcatheter closure of fistulae using coils is preferred as an effective and safe alternative to surgery. Here we report the case of a patient with congenital coronary artery fistulae arising from both the left and right coronary arteries draining individually into the right pulmonary artery treated successfully with a transcatheter approach.

Diagnostic value of strain echocardiography, galectin-3, and tenascin-C levels for the identification of patients with pulmonary and cardiac sarcoidosis.

BACKGROUND: Cardiac involvement in sarcoidosis has been associated with poor prognosis. We evaluated myocardial contractility quantitatively in a cohort of pulmonary sarcoidosis (PS) patients with and without cardiac involvement. We also studied markers of fibrosis (tenascin-C [Tn-C] and galectin-3 [Gl-3]) as diagnostic tools for PS and cardiac sarcoidosis (CS). METHODS: Forty ambulatory patients with PS of grades 1-2 and 26 healthy subjects were prospectively enrolled. All patients with PS underwent cardiac magnetic resonance (CMR) to explore the presence of CS. The study population was divided into three groups: controls (n = 26), non-CS patients (n = 34), and CS patients (n = 6). Speckle-tracking strain echocardiography (STE) was performed on all patients, and Gl-3 and Tn-C values were measured in all patients and controls. RESULTS: PS patients had higher levels of Gl-3 and Tn-C than did controls, and the STE parameters of PS patients, including global longitudinal strain (GLS) and global circumferential strain (GCS), were lower than those of controls (p < 0.001 for all comparisons). GLS values were lower in CS patients than in the other groups (p = 0.05). CONCLUSIONS: PS patients demonstrate reduced cardiac contractility, independent of CMR-proven structural cardiac lesions, while patients with structural lesions have a more pronounced drop in strain parameters. Tn-C and Gl-3 are promising markers for the diagnosis of PS, but they are not specific for cardiac involvement.

Novel fibro-inflammation markers in assessing left atrial remodeling in non-valvular atrial fibrillation.

BACKGROUND: Structural remodeling is associated with the fibroinflammatory process in the atrial extracellular matrix. In the present study we aimed to investigate whether serum levels of new circulating remodeling markers differ in patients with atrial fibrillation (AF) compared to patients with sinus rhythm. MATERIAL AND METHODS: The study population included 52 patients diagnosed with non-valvular AF and 33 age-matched patients with sinus rhythm. Serum levels of Galectin-3, matrix metalloproteinase-9 (MMP-9), lipocalin-2 (Lcn2/NGAL), N-terminal propeptide of type III procollagen (PIIINP), Hs-Crp, and neutrophil-to-lymphocyte ratio (NLR) were measured. The left atrial volume (LAV) was calculated by echocardiographic method and LAV index was calculated. RESULTS: Galectin-3, MMP-9, and PIIINP levels were significantly higher in AF patients except NGAL levels (1166 pg/ml (1126-1204) and 1204 pg/ml (1166-1362) p=0.001, 104 (81-179) pg/ml and 404 (162-564) pg/ml p<0.0001, and 1101 (500-1960) pg/ml and 6710 (2370-9950) pg/ml p<0.0001, respectively). The NLR and Hs-CRP levels were also higher in AF (2.1 ± 1.0 and 2.7 ± 1.1 p=0.02 and 4.2 ± 1.9 mg/L and 6.0 ± 4.7 mg/L p=0.04, respectively). In correlation analyses, NLR showed a strongly significant correlation with LAVi, but Hs-CRP did not (p=0.007 r=0.247, Pearson test and p=0.808 r=0.025, Pearson test, respectively). Moreover, Galectin-3, MMP-9, and PIIINP had a strong positive correlation with LAVi (p=0.021 r=640, Spearman test and p=0.004 r=0.319 Pearson test, and p=0.004 r=0.325 Pearson test, respectively). CONCLUSIONS: Novel fibrosis and inflammation markers in AF are correlated with atrial remodeling. Several unexplained mechanisms of atrial remodeling remain, but the present study has taken the first step in elucidating the mechanisms involving fibrosis and inflammation markers.

Neutrophil-to-lymphocyte ratio and in-hospital mortality in patients with acute heart failure.

OBJECTIVES: Previous studies have demonstrated the role of inflammation in acute heart failure. The neutrophil-to-lymphocyte ratio was found to be a useful inflammatory marker for predicting adverse outcomes. We hypothesized that an elevated neutrophil-to-lymphocyte ratio would be associated with increased mortality in acute heart failure patients. METHODS: The study cohort consisted of 167 acute heart failure patients with an ejection fraction <50%. The primary endpoint was in-hospital mortality, and the patients were divided into two groups according to in-hospital mortality. RESULTS: In a multivariate regression analysis, including baseline demographic, clinical, and biochemical covariates, the neutrophil to lymphocyte ratio remained an independent predictor of mortality (OR 1.156, 95% CI 1.001 - 1.334, p = 0.048). CONCLUSION: In conclusion, an elevated neutrophil-to-lymphocyte ratio seems to be a predictor of short-term mortality in patients with acute heart failure and a reduced left ventricular ejection fraction.

A giant right atrial villous myxoma with simultaneous pulmonary embolism.

INTRODUCTION: Primary cardiac tumors are rare and approximately three quarters of them are benign and up to half of the benign tumors are myxomas. Right atrial villous myxoma with pulmonary embolism is an unusual apparition. PRESENTATION OF CASE: A 29 year-old male was admitted to our outpatient clinic with progressive exertional dyspnea, chest pain and intermittent feeling faint. A giant right atrial villous mobile mass was detected by means of transthoracic echocardiography. To exclude possible pulmonary embolism, chest computed tomography scan was performed and showed filling defects in the branch of the pulmonary artery. The mass was totally resected. DISCUSSION: RA villous myxoma is a rare subtype in an unusual location with high potential of pulmonary embolism. Early surgery for villous myxoma has a great importance in order to reduce the risk of pulmonary embolism. CONCLUSION: 3D TEE should be a sufficient technique for diagnosis and evoluation of shape, size and origin of the cardiac mass an adequate guide to surgical treatment.

Serum gamma-glutamyl transferase levels and in-hospital mortality in patients with acute heart failure.

BACKGROUND: Acute heart failure (AHF) is a major cause of hospitalisation, morbidity and mortality worldwide. Gamma-glutamyl transferase (GGT) is an enzyme responsible for the extracellular catabolism of antioxidant glutathione and a potential risk indicator of cardiac mortality. Limited data exists on the prognostic value of circulating levels of GGT in patients hospitalized due to AHF. AIM: To study the association between baseline GGT activity and in-hospital mortality in AHF patients. METHODS: The study cohort consisted of 183 AHF patients with left ventricular ejection fraction (LVEF) < 50%. The primary endpoint was in-hospital mortality. Patients were divided into two groups according to in-hospital mortality. The relationship between GGT activity and in-hospital mortality was tested using logistic regression models, adjusting for clinical characteristics and echocardiographic findings. RESULTS: After adjustment for possible confounders, GGT level was significantly related (OR 1.056, 95% CI 1.018-1.096, p = 0.04) to in-hospital mortality. CONCLUSIONS: Elevated GGT activity is an independent predictor of short-term mortality in patients with AHF and reduced LVEF.

Comparison of single-dose and repeated levosimendan infusion in patients with acute exacerbation of advanced heart failure.

BACKGROUND: Levosimendan (LS) is a novel inodilator that improves cardiac performance, central hemodynamics, and symptoms of patients with decompensated chronic heart failure. The aim of this study was to compare the effects of single and repeated LS infusion on left ventricular performance, biomarkers, and neurohormonal activation in patients with acute heart failure. MATERIAL AND METHODS: Twenty-nine consecutive patients with acute exacerbation of advanced heart failure were included in this study. LS was initiated as a bolus of 6 µg/kg followed by a continuous infusion of 0.1 µg/kg/min for 24 hours in both groups who received intravenous single and repeated (baseline and at 1 and 3 months) treatment. Physical examination, echocardiography, and biochemical tests (brain natriuretic peptide, tumour necrosis factor-alpha, interleukin-1beta, 2, and 6) were performed before treatment and on 3 day of the treatment. The last evaluation was performed at 6 month after the baseline treatment. RESULTS: Twenty male and 9 female patients with mean age of 60.2 ± 7.4 years were included in this study. A significant improvement in New York Heart Association functional status and myocardial performance index was detected only in the repeated LS treated patients at 6 month compared to the pretreatment status (p=0.03 and p<0.001; respectively). In addition, a significant decrease in brain natriuretic peptide (p<0.01) and plasma interleukin-6 (p=0.05) levels were also achieved only in patients who were given repeated LS. CONCLUSIONS: Our study showed that repeated LS treatment is more effective compared to the single dose LS treatment in improving clinical status, hemodynamic and laboratory parameters in patients with acute exacerbation of advanced heart failure.

Epicardial fat thickness in patients with psoriasis vulgaris.

OBJECTIVES: Psoriasis vulgaris is one of the most common skin disorders. Patients with psoriasis carry an excessive risk of coronary artery disease. Visceral adipose tissue around the heart affects the heart and coronaries by secreting proatherogenic mediators. It can be evaluated easily by measurement of epicardial fat thickness (EFT). The aim of this study was to investigate EFT in patients with psoriasis vulgaris. STUDY DESIGN: One hundred and fifteen adult patients (62 male; mean age 33.6±6.0 years) with psoriasis vulgaris (Group 1) and 60 age- and sex-matched healthy individuals (28 male; mean age, 32.5±8.3 years) (Group 2) were included in this study. EFT was obtained by transthoracic echocardiography. Disease-specific characteristics of the patients were recorded. Serum glucose, lipid profile and high-sensitive C-reactive protein (hs-CRP) levels were measured. RESULTS: EFT and hs-CRP were significantly higher in Group 1 than in Group 2 (5.7±1.2 vs. 4.1±1.0 mm, p<0.001 and 0.52±0.45 mg/dl vs. 0.19±0.17 mg/dl, p<0.001, respectively). The psoriasis disease activity score and hs-CRP were found to be independent predictors of EFT in patients with psoriasis vulgaris (ß=0.21, t=2.67, p=0.01 and ß=0.62, t=7.72, p=0.001, respectively). CONCLUSION: Our findings indicate that EFT was significantly higher in patients with psoriasis vulgaris compared with the controls. It was more prominent in patients with severe disease.

Transcatheter trans-apical closure of paravalvular mitral and aortic leaks using a new device: first in man experience.

This report describes the first use of a new paravalvular leak (PVL) device designed specifically to close paravalvular mitral and paravalvular aortic leaks. The first patient had severe paravalvular mitral leak that was closed using the transapical route with a rectangular designed PVL device that has an oval waist for self-centering and the second patient had moderate paravalvular aortic leak that was closed with a square designed device that has a round waist for self-centering. Both patients had complete closure.

A new parameter predicting chronic total occlusion of coronary arteries: platelet distribution width.

Platelet distribution width (PDW) measures the variability in platelet size and is a marker of platelet activation. We investigated whether PDW is associated with the extent of coronary artery disease (CAD) and coronary total occlusions (CTOs). We studied 162 patients: 108 had a coronary lesion with a diameter stenosis of ≥50%, the CAD(+) group, and 54 patients had normal coronary anatomy, the CAD(-) group. The CAD(+) group was subdivided into CAD(+) CTO(+) and CAD(+) CTO(-) groups. Among patients with CAD, the CTO(+) group had a significantly greater PDW (%) than the CTO(-) group (16.9 ± 2.8, 15.4 ± 3.0, and 15.4 ± 1.9, respectively; P = .008). In a receiver-operating characteristic analysis, a PDW cut point of 15.7% was identified in patients with CTO(+) (area under curve = 0.64, 95% confidence interval 0.54-0.75). A PDW value of more than 15.7% demonstrated a sensitivity of 64% and a specificity of 66%. The PDW is a simple platelet index that may predict the presence of CTO.

Association between serum cystatin C levels and coronary slow flow.

We assessed the association between serum cystatin C (CysC) levels and coronary slow flow (CSF) phenomenon in patients who underwent coronary angiography. A total of 210 patients (mean age 55.6 ± 10.9 years; 100 females) were included. Patients were divided into 3 groups, (patients with CSF [group 2], with coronary artery disease [CAD; group 3], and without CAD [group 1]). Serum CysC levels in patients with CSF were significantly lower than those with and without CAD (912.5 ± 135.6, 820.4 ± 104.2, and 1343.4 ± 236.6 ng/mL in groups 1, 2, and 3, respectively; P < .001). Serum CysC levels correlated with the number of vessels with CSF and mean corrected thrombolysis in myocardial infarction frame count (Spearman correlation coefficient [r s] = .192, P < .001 and r s = .261, P < .001 respectively). In conclusion, patients with CSF have lower CysC levels; this could be a useful biomarker of CSF involvement in patients who undergo diagnostic coronary angiography.

Does estimated glomerular filtration rate have an effect on left ventricular function after ST-elevation myocardial infarction?

OBJECTIVES: Little is known about whether estimated glomerular filtration rates (eGFR) affect left ventricular (LV) function and gain benefit with antiremodeling treatment in patients with ST-elevation myocardial infarction (STEMI). We investigated the effect of eGFR on LV function using tissue Doppler imaging (TDI) parameters. In addition, we sought to evaluate the antiremodeling effect of standard treatment at follow-up in patients with renal insufficiency (RI) after STEMI. METHODS AND RESULTS: A retrospective analysis of 579 patients with STEMI was performed. Patients were divided into 3 groups according to eGFR (Group 1: eGFR > 90 mL/min per 1.73 m(2); Group 2: eGFR = 60-89 mL/min per 1.73 m(2); Group 3: eGFR < 60 mL/min per 1.73 m(2)). Conventional echocardiography and TDI were performed within 48-72 hours after STEMI and at 6-month follow-up. The mean left ventricular ejection fraction (LVEF) was significantly lower in Group 3 than in Group 1 (P = 0.021). The mean peak systolic velocity (Sm) was significantly lower in Group 3 than in Group 1 and Group 2 (P = 0.002 and 0.006, respectively). The estimated GFR had a linear association with Sm and LVEF (P = 0.001, r = 0.161; P = 0.005, r = 0.132, respectively). Multivariate analysis showed that an eGFR < 60 mL/min per 1.73 m(2) was an independent predictor of lower Sm and in-hospital mortality. In addition, an antiremodeling effect of standard treatment was seen in all groups at 6-month follow-up. CONCLUSIONS: Estimated glomerular filtration rate of <60 mL/min per 1.73 m(2) was associated with lower LV function after STEMI, and may gain an antiremodeling effect with standard treatment at follow-up.
