Background The aim of this study was to assess whether epicardial fat thickness (EFT) is associated with the severity of heart failure in patients with nonischemic dilated cardiomyopathy (NICMP). Methods The study group was composed of 93 patients with NICMP and38 age- and sex-matched healty individuals as the control group. The EFT was identified during end-systole at the point on the free wall of the right ventricle. Results Patients with NICMP had significantly lower mean EFT than those in the control group (4.1 ± 0.8 vs. 6.1 ± 1.8 mm, P < 0.001). EFT was thinnest in patients with New York Heart Association (NYHA) functional class III or IV (3.5 ± 0.5, P < 0.001). There was a significant correlation between EFT, left ventricle EF (r = 0.540 P < 0.001), and B-type natriuretic peptide (BNP) (r = -0.695, P < 0.001) values in patients with NICMP. In addition, when EFT was corrected for BMI, EFT/BMI was lower in patients with NYHA functional class III-IV than patients with NYHA class I-II and control group (0.13 ± 0.01, 0.16 ± 0.02, 0.23 ± 0.04, respectively; P < 0.001). There was a significant correlation between EFT/BMI, left ventricle EF (r = 0.489, P < 0.001), and BNP (r = -0.549, P < 0.001) in patients with NICMP. In multivariate regression analysis, EFT (P = 0.009), BNP (P = 0.039), and left atrium volume index (P = 0.039) were independently associated with impaired functional status. Conclusion Echocardiographic EFT is an inexpensive, simple, and readily available marker that may be used to asses the severity of chronic heart failure in patients with NICMP. © 2014, Wiley Periodicals, Inc.

Relation of plasma fibrinogen levels with extent, severity, and complexity of coronary artery disease (CAD) in patients with stable angina pectoris (SAP) has not been adequately investigated. The aim of this study was to evaluate whether plasma fibrinogen level is associated with coronary complexity, severity, and extent assessed by SYNTAX (Synergy between percutaneous coronary intervention with TAXUS and Cardiac Surgery) score (SS).We enrolled 134 consecutive patients with SAP who underwent coronary angiography. Baseline serum fibrinogen levels were measured, and SS was calculated from the study population. The patients were classified into 3 groups by tertiles of SS (SS, control group = 0; intermediate group < 22; and high group 22).Plasma fibrinogen levels demonstrated a stepwise increase from control group to high SS group. There was a strong correlation between fibrinogen and the SS (r = .535, P < .001). Area under the receivers operating characteristic curve of fibrinogen was 0.72 (95% confidence interval [CI] 0.61-0.82; < .001) for predicting a high SS. Fibrinogen value higher than 411 mg/dL has a sensitivity of 75% and a specificity of 64% in prediction of high SS. In multivariate analyses, plasma fibrinogen was observed to be an independent predictor for high SS in patients with stable CAD (odds ratio [OR] 1.01; 95% CI, 1.01-1.02; P < .001).Plasma fibrinogen is a readily measurable systemic inflammatory marker and is independently associated coronary severity and complexity in patients with CAD.

Objectives. The aim of this study was to assess whether NLR levels are associated with echocardiographic parameters, New York Heart Association (NYHA) functional class, or B-type natriuretic peptide (BNP) levels in patients with idiopathic dilated cardiomyopathy (DCM). Design. Eighty-seven patients with idiopathic DCM were included prospectively from 2009 to 2014. Patients with acute decompensated heart failure and conditions that alter the total or differential white blood cell counts were excluded. Blood samples were collected before echocardiographic investigation on admission. Results. There was a statistically significant correlation between neutrophil/lymphocyte ratio (NLR) and NYHA functional class (r = 0.68, p < 0.001), BNP levels (r = 0.61, p < 0.001) and various echocardiographic parameters. NLR was significantly higher in patients in NYHA functional class III or IV (n = 39) than among those categorized as NYHA class I or II (n = 48), (3.3 ± 1.0 vs 2.1 ± 0.6; p < 0.001). The NLR cutoff value predicting severe chronic HF was 2.25 with 82% sensitivity and 65% specificity (p < 0.001). On multivariate linear regression analysis NLR (p = 0.025), left ventricular end-diastolic volume (p = 0.041) and left atrial volume index (LAVI) (p = 0.001) were found to be independent positive predictors of BNP levels. Conclusion. Neutrophil/Lymphocyte ratio is associated with the severity of chronic heart failure in patients with idiopathic DCM. © 2014 Informa Healthcare.

Background: Left ventricular non-compaction (LVNC) is a specific cardiomyopathy that occurs following a disruption of endomyocardial morphogenesis. This study presents clinical findings, diagnostic features, treatment and follow-up of pediatric patients diagnosed with LVNC. Methods: Patients with LVNC who were followed from January 2006 to March 2010 were included in this study. Diagnosis was made with the use of characteristic findings of magnetic resonance imaging and echocardiography. Holter electrocardiography and metabolic screening tests were also performed in all patients. Results: A total of 24 patients were studied (18 male, six female). Patient age at diagnosis was 50 ± 60 months (eight days to 15 years). Average follow-up period was 22 ± 12 months (four months to four years). Findings at diagnosis were as follows: eight (33%) patients had heart failure, five (20%) had rhythm abnormalities, five (20%) had cardiomegaly, two had murmurs, two had cyanosis, and two presented with fatigue. Ten (41%) patients had been followed previously with other diagnoses. In 21 (87.5%) patients, electrocardiographic abnormalities were noted, especially left ventricular hypertrophy and ST-T changes. Patients had an average ejection fraction of 46% (18-73%) and three of them had additional congenital heart disease (patent ductus arteriosus, aortopulmonary window and complex cyanotic heart disease). Scanning for metabolic diseases revealed fatty acid oxidation disorder in one patient, and mitochondrial disease in another. During follow-up, a permanent pacemaker was implanted in a patient with severe bradycardia and ventricular dysfunction, and three patients died. Conclusion: LVNC can be diagnosed at any age from newborn to adolescent and has a variable clinical course. Closer study of patients with cardiomegaly and heart failure can reduce delays in diagnosis of LVNC. © 2011 Via Medica.

Elevated gamma-glutamyltransferase (GGT) level is independently correlated with conditions associated with increased atherosclerosis, such as obesity, elevated serum cholesterol, high blood pressure and myocardial infarction. It is demonstrated that serum GGT activity is an independent risk factor for myocardial infarction and cardiac death in patients with coronary artery disease. Diabetes is also a well-known cardiovascular risk factor and an equivalent of coronary artery disease. Although the relationship between GGT and coronary artery disease has been reported, there are limited data exploring the changes of GGT in acute coronary syndromes, especially in patients with diabetes. So, this study aimed to determine changes in GGT level in diabetic and non-diabetic acute coronary syndromes. This trial was carried out at Kosuyolu Cardiovascular Training and Research Hospital and Van Yuksek Ihtisas Hospital, Turkey. A total of 219 patients (177 men and 42 women) presenting with acute coronary syndrome) and 51 control subjects between September 2007 and September 2008 were included in the study. Serum γ-glutamyltransferase and serum lipoprotein levels were determined. The resuls indicated that serum GGT levels were higher in acute coronary syndrome patients compared with control. In subgroup analyses, there was no difference between diabetic and non-diabetic subgroups. There was also weak correlation between GGT and blood glucose levels. There was no correlation between GGT and serum lipoprotein levels. In conclusion, serum GGT levels were higher in acute coronary syndrome patients. In subgroup analyses, There was no difference between diabetic and non diabetic subgroup. © 2010 Springer-Verlag.

Aneurysms of the sinus of Valsalva are rarely diagnosed cardiac anomalies, occurring in 0.14%-0.96% of patients who have undergone open heart surgical procedures. The most common congenital anomalies accompanying sinus of Valsalva aneurysm (SVA) are ventricular septal defect, bicuspid aortic valve, atrial septal defect, and coarctation of aorta. We report a patient with an unruptured right SVA presenting with severe right ventricular outflow tract (RVOT) obstruction, and coexisting patent foramen ovale (PFO) with a right to left shunt. It could be assumed that the increase in right atrial pressure due to RVOT obstruction had led to a right to left shunt across the patent foramen ovale. © 2010, Wiley Periodicals, Inc.

No gold standard exists for grading tricuspid regurgitation (TR) severity. We developed a simple parameter, the right ventricular (RV) early inflow-outflow (RVEIO) index, using the early diastolic filling velocity and RV outflow velocity integrated over the systolic ejection period. We hypothesized that this index would help identify severe TR in clinical practice.We obtained data from routine transthoracic echocardiograms. All records reporting moderate (n=395) or severe (n=395) TR were reanalyzed to measure vena contracta (VC) width, TR jet area, effective regurgitant orifice (EROA) derived with the proximal isovelocity surface area method, RVEIO index, and right-sided chamber volumes.Significant linear trends were demonstrated for right atrial volume index, end-diastolic volume index, E-wave velocity, RV velocity time integral, TR jet area, VC width, and EROA with increasing TR severity. Independent predictors of severe RT included RVEIO index 10, VC width 0.7cm, TR jet area>10cmRVEIO index is a useful, simple, accurate, and independent predictor of severe TR that adds incrementally to traditional methods of quantifying TR severity. Accurate quantification and classification of TR severity is critical for clinical decision-making and management; therefore, the incorporation of RVEIO index into the integrative approach to grading TR severity should be considered.
