BACKGROUND Left ventricular noncompaction is a cardiomyopathy characterized by excessive trabeculation of the left ventricle, progressive myocardial dysfunction, and early mortality. Left ventricular noncompaction has a heterogeneous clinical presentation that includes arrhythmia and sudden cardiac death. METHODS AND RESULTS We retrospectively reviewed all children diagnosed with left ventric...

Anthracyclines (i.e., doxorubicin, daunorubicin) have significant impact on outcome in many pediatric chemotherapy protocols and therefore remain the mainstay of treatment. The objective of this study was to identify the risk factors for anthracycline induced cardiac dysfunction in pediatric patients. Multiple logistic regression model was applied to assess the risk factors for development of c...

Aging results in a redistribution of polyunsaturated fatty acids (PUFAs) in myocardial phospholipids. In particular, a selective loss of linoleic acid (18:2n6) with reciprocal increases of long-chain PUFAs (eg, arachidonic and docosahexaenoic acids) in the mitochondrial phospholipid cardiolipin correlates with cardiac mitochondrial dysfunction and contractile impairment in aging and related pat...

Although alterations in the size and shape of the heart (cardiac remodeling) are considered in explaining cardiac dysfunction during the development of congestive heart failure (CHF), there are several conditions including initial stages of cardiac hypertrophy, where cardiac remodeling has also been found to be associated with either an increased or no change in heart function. Extensive studie...

B-type natriuretic peptide (BNP) and amino-terminal pro-BNP (NT-proBNP) plasma levels are commonly high at the early phase of septic shock and have been suggested to be prognostic markers for this condition. It is uncertain, however, whether this increase reflects sepsis related cardiac dysfunction. In a recent issue of Critical Care, Mokart and coworkers showed the accuracy of NT-proBNP in pre...

Sepsis is an exaggerated systemic inflammatory response to persistent bacteria infection with high morbidity and mortality rate clinically. β-arrestin 2 modulates cell survival and cell death in different systems. However, the effect of β-arrestin 2 on sepsis-induced cardiac dysfunction is not yet known. Here, we show that β-arrestin 2 overexpression significantly enhances animal survival follo...

Background: Patients undergoing cardiac surgery are at increased risk of bleeding due to multifactorial coagulopathies. In the present study, we aimed at investigating the changes in platelet count and function during and after surgery as well as determining the association of the platelet dysfunction with bleeding and transfusion requirements in these patients.    Methods: A total o...

Uremic Cardiomyopathy thought to be the pathological cardiac hypertrophy, indicating influence of impaired renal function on myocardium. It is result pressure overload, volume and uremic state itself. LV overload occurs frequently from hypertension arteriosclerosis, occasionally aortic stenosis; as a presence an arteriovenous fistula, anemia, hypervolemia. Cardiovascular complications are major...

Postoperative pulmonary complications are the most frequent and significant contributor to morbidity, mortality, and costs associated with hospitalization. Interestingly, despite the prevalence of these complications in cardiac surgical patients, recognition, diagnosis, and management of this problem vary widely. In addition, little information is available on the continuum between routine post...
