Prognostic role of echocardiographic and hematologic parameters in heart failure patients complicated with incidental pleural effusion diagnosed during echocardiographic evaluation

We aimed to determine long-term prognostic role of echocardiographic and hematologic parameters in heart failure patients complicated with incidental pleural effusion (PE) diagnosed during echocardiographic evaluation. The study was performed by evaluating patient records in which PE was incidentally detected during echocardiographic examination in a tertiary teaching hospital between Jan 2002 and Dec 2012. Total 151 patients with heart failure complicated with PE were analyzed. All patients’ mortality data were collected from registry center of Social Insurance Institution which is officially responsible for recording all mortality data in Turkey. Detailed echocardiographic and hematologic parameters including creatinine, uric acid, albumin, sodium, potassium, hemoglobin at the time of hospital admission were analyzed. Data from 151 eligible patients were analyzed. We compared patients who died (n = 51) during follow-up with the survivors (n = 100) in terms of patients’ echocardiographic and hematological features. Mean duration of follow-up was 71.5 ± 45.6 months. Fifty-one patients (33.8 %) died during this follow-up period. From all echocardiographic parameters only dilated left atrium (LA) diameter was found to be associated with a poor prognosis (p = 0.034). Low albumin, sodium and hemoglobin levels were associated with poor prognosis (p < 0.001, p = 0.002 and p = 0.007, respectively). We showed that dilated LA, as well as low albumin, low sodium and low hemoglobin levels had a worse prognostic significance than patients with normal LA size, within normal limits of albumin, sodium and hemoglobin levels in patients with heart failure complicated with PE determined incidentally by echocardiography.     

P-wave dispersion between transcatheter and surgical closure of secundum-type atrial septal defect in childhood

Patients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood. A total of 68 children (the mean age was 7.2 plus or minus 3.3 years; the mean secundum atrial septal defects diameter was 17.3 plus or minus 5.4 millimetres) were evaluated in this study. Transcatheter closure was attempted in 41 children with secundum atrial septal defects, and the defect in 27 patients was closed by surgical techniques. P maximum, P minimum and P dispersion were measured by the 12-lead surface electrocardiography. P maximum, P minimum and P dispersion were found to be similar in patients with pre- and post-procedure (98.0 plus or minus 19.3 versus 95.1 plus or minus 23.0 milliseconds; 68.0 plus or minus 20.8 versus 67.6 plus or minus 24.3 milliseconds, 29.9 plus or minus 11.0 versus 27.1 plus or minus 12.1 milliseconds, respectively). There was no statistical significance in the comparison of P dispersion between the two groups. But in the surgical group, P-wave dispersion was decreased more significantly compared with baseline values (p-value equal to 0.03). In conclusion, there is no P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure of secundum atrial septal defect.     

The influence of iloprost on acute lung injury induced by hind limb ischemia-reperfusion in rats

The local ischemia-reperfusion (I/R) process gains a systemic nature and affects distal organs. The remote effects of I/R are most frequently observed in the lungs and pulmonary damage may vary from acute lung injury with mild dysfunction to severe respiratory failure or the acute respiratory distress syndrome. In this hind limb I/R induced experimental lung injury model two groups of rats as IR and ILO were determined. Both groups underwent 60 min of ischemia and 120 min of reperfusion. While ILO group received iloprost in saline, IR group received only saline before reperfusion period intravenously. Serum myeloperoxidase (MPO) activity, malondialdehyde (MDA) levels and total antioxidant capacity (TAC) and lung tissue MPO activity, MDA levels and Na+-K+ ATPase activity were measured and light microscopic analyses of lung specimens were performed. The MPO activities in serum and lung homogenates were found to be significantly decreased in ILO group (P < or = 0.01). The MDA levels in lung homogenates were found to be significantly decreased in ILO group (P < or = 0.01), but the decreases were not significant in serum MDA levels (P=0.052). Serum TAC and lung tissue Na+-K+ ATPase activity levels were found to be increased in ILO group compared to IR group (P < or = 0.01). Lung histology showed marked improvement by iloprost compared to the IR group in this study. Iloprost has been found to be effective in attenuating ischemia reperfusion-induced remote organ damage, in this case, lung injury, in rats.     

Coronary narrowing secondary to compression by pericardial hydatid cyst

Echinococcus granulosus remains a clinical problem in undeveloped and developing countries. It commonly affects the liver and lung, but, rarely, other organs such as the heart can be involved. In this report, we describe an unusual case in which pericardial hydatid cyst mimicking acute coronary syndrome secondary to compression by pericardial hydatid cyst attached to the anterolateral wall of the left ventricle. We made diagnosis by transthoracic 2D echocardiography, and confirmed by cardiac magnetic resonance imaging and serologic tests. Because our patient refused to have an operation, albendazole therapy was given. It is important to recognize this unusual disease, because it may lead to serious complications.     

The relationship between leptin and lipids in atherosclerosis

BACKGROUND: This study aimed to examine the extent to which leptin, alone or in combination with other risk factors, may be an independent marker for myocardial infarction in a region with a high incidence of cardiovascular disease. METHODS AND RESULTS: Leptin levels were measured by the ELISA method, while plasma lipids and lipoproteins were measured by conventional methods. Leptin levels were significantly higher in the patient than in the control group. Serum total cholesterol, low-density lipoprotein, lipoprotein (a) and apolipoprotein B showed a significant correlation with leptin, while high-density lipoprotein showed an inverse relation. CONCLUSIONS: Our results suggest that leptin may be one factor operating in the metabolic alteration taking place during myocardial infarction, and is a possible risk factor.     

Impact of invasive strategy for the management of patients with cardiogenic shock after acute myocardial infarction

OBJECTIVE: This study evaluates the influence of early revascularization (with percutaneous transluminal coronary angioplasty (PTCA) and coronary surgery) on short- and long-term survival in patients with cardiogenic shock complicating acute myocardial infarction (AMI). METHODS AND RESULTS: In-hospital and 6-month survival were retrospectively determined on day 193 (65-270, median +/- 25th and 75th percentiles) in 87 patients who either underwent early invasive reperfusion (group A, n=60) or those who were treated conservatively (group B, n=27). In-hospital mortality was 37% in group A and 56% in group B (P=0.192). Six-month mortality was statistically lower in group A than in group B (30 patients (50%) compared with 25 patients (93%), P=0.005). Being a woman and older age were found to be factors increasing mortality. Lower mortality in the long term was strongly associated with revascularization (odds ratio=0.08, 95% confidence interval=1.54-109). PTCA was found to be an independent predictor of long-term survival (odds ratio= 0.22, 95% confidence interval=0.049-1.00, P=0.050), by multiple logistic regression. CONCLUSIONS: In conclusion, this study suggests that early revascularization improves long-term survival of patients with cardiogenic shock complicating AMI, even after adjustment for baseline differences between patients who underwent early revascularization and those who did not.
