Hearts utilize fatty acids as a primary source of energy. The sources of those lipids include free fatty acids and lipoprotein triglycerides. Deletion of the primary triglyceride-hydrolyzing enzyme lipoprotein lipase (LPL) leads to cardiac dysfunction. Whether heart LPL-knockout (hLPL0) mice are compromised due a deficiency in energetic substrates is unknown. To test whether alternative sources...
Cardiac dysfunction is an important and independent risk factor for the future development of clinical heart failure (HF). Early recognition and treatment of American College of Cardiology Foundation/American Heart Association stage B HF, defined as cardiac dysfunction without signs or symptoms of HF, is a potentially powerful strategy to prevent progression to American College of Cardiology Fo...
Cardiopulmonary bypass and cardioplegic arrest, which allow for support of the circulation and stabilization of the heart during cardiac procedures, are still used for the vast majority of cardiac operations worldwide. However, in addition to a well-recognized systemic inflammatory response, cardiopulmonary bypass and cardioplegic arrest elicit complex, multifactorial vasomotor disturbances tha...
Introduction: Chest X–Ray is one of the most common method of imaging. Cardio Thoracic Ratio ( CTR ) is one of the parameters of Chest X–Ray that is used for determining cardiac enlargement. Echocardiography as compared to Chest X–Ray is expensive and all centers dont have it, but it can determine heart size, valvular diseases, Ejection Fraction, Left Ventricular Hypertrophy (LVH), Pericardial...
BACKGROUND Myocardial hypertrophy and dysfunction are key features of metabolic heart disease due to dietary excess. Metabolic heart disease manifests primarily as diastolic dysfunction but may progress to systolic dysfunction, although the mechanism is poorly understood. Liver kinase B1 (LKB1) is a key activator of AMP-activated protein kinase and possibly other signaling pathways that oppose ...
An abrupt elevation in aminotransferases without clear etiology may be attributed to hypoxic hepatitis. Underlying cardiac dysfunction, an important clinical clue, is often overlooked as a cause of hypoxic hepatitis, and understanding the interdependence of the heart and liver is crucial in making this diagnosis. Causes of cardiac dysfunction may include any of many different diagnoses; infiltr...
In the last decades the prevalence of non-alcoholic fatty liver disease (NAFLD) has increased as a consequence of the childhood obesity world epidemic. The liver damage occurring in NAFLD ranges from simple steatosis to steatohepatitis, fibrosis and cirrhosis. Recent findings reported that fatty liver disease is related to early atherosclerosis and cardiac dysfunction even in the pediatric popu...
Cardiac dysfunction following acute myocardial infarction is a major cause of death in the world and there is a compelling need for new therapeutic strategies. In this report we demonstrate that a direct cardiac injection of drug-loaded microparticles, formulated from the polymer poly(cyclohexane-1,4-diylacetone dimethylene ketal) (PCADK), improves cardiac function following myocardial infarcti...
The incidence and prevalence of dyspnea increases with age. Frequently, for the general practitioner with his limited diagnostic facilities, it is impossible to separate dyspnea from cardiac causes and non-cardiac causes. Without cardiac imaging it is also impossible to separate systolic dysfunction from diastolic dysfunction. After a thorough physical examination, initial screening of systolic...
