ABSTRACT: Understanding heart metabolism during preservation is crucial to develop new effective cardioplegic solutions. We aim to investigate metabolic alterations during heart preservation in the clinically used Celsior (Cs) and Histidine Buffer solution (HBS). We also focused in gender-specific metabolic adaptations during ischemia.We followed energy metabolism in hearts from males ...

Stable angina is a form of coronary artery disease. Its potential to progress requires the most appropriate treatment in order to reduce the incapacitating effect of an acute angina attack and to avoid long-term cardiovascular events. With or without revascularization, pharmacological treatment is an essential component of this treatment strategy, ...

The function of the right ventricle (RV) in heart failure (HF) has been mostly ignored until recently. A 2006 report of the National Heart, Lung, and Blood Institute identified a gap between RV research efforts and its clinical importance compared with that of the left ventricle. This recent shift in ...

Vitamin D has recently been suggested as an important mediator of blood pressure and cardiovascular disease, including heart failure. In patient with heart failure, low vitamin D levels are associated with adverse outcome and correlate with established clinical correlates and biomarkers. Many precursor states of heart failure, such as hypertension, ...

Chronic ischemia or pressure overload decreases thyroid hormone (TH) signaling and activates the fetal gene program in the heart. While these features are of physiologic importance in the developing heart, their respective roles in the postnatal heart are debated. Administration of TH can prevent the changes of the fetal gene ...

Secondary hyperparathyroidism (SHPT) may contribute to the systemic illness that accompanies chronic heart failure (CHF). Healthy elderly with vitamin D deficiency who did not develop hyperparathyroidism (functional hypoparathyroidism, FHPT) had lower mortality than those who did. This study was designed to examine determinants of the PTH response in the vitamin ...

As more patients survive myocardial infarctions, the incidence of heart failure increases. After an infarction, the human heart undergoes a series of structural changes, which are governed by cellular and molecular mechanisms in a pathological metamorphosis termed "remodeling." This review will discuss the current developments in our understanding of these ...

Glucagon-like peptide-1 (GLP-1) is involved in satiety control and glucose homeostasis. Besides, GLP-1 has cardiovascular effects. In experimental models, GLP-1 increases cardiac output and exerts a direct vasodilatory effect. In animals with dilated cardiomyopathy GLP-1 improves left ventricular performance. Human data demonstrated that GLP-1 reduces arterial blood pressure, improves endothelial ...

We report a case of a 78-year-old woman with cardiac sarcoidosis with a history of syncope and palpitation. Further assessment with echocardiography, gadolinium-enhanced cardiovascular magnetic resonance (CMR) and histology led to a diagnosis of cardiac sarcoidosis. As the patient suffered from ventricular tachycardia (VT) despite active corticosteroid therapy, an implantable ...

Heart failure is a major source of cardiovascular morbidity, including acute decompensations requiring hospitalization. Because most therapeutic interventions in acute heart failure target optimization of cardiac output and volume status, accurate assessment of these parameters at the point of care is critical to guide management. However, physician bedside assessments of ...

Chronic heart failure is a major public health problem causing considerable morbidity and mortality. Recent studies have shown that an elevated plasma level of homocysteine is a strong independent risk factor for heart failure, in addition to atherosclerotic disease. Preclinical studies have demonstrated that induced hyperhomocysteinemia acts via multiple pathogenic ...

Relaxin, a naturally-occurring hormone in the insulin family, was discovered to have a physiologic role in pregnancy. Named initially for its relaxing effect on the pubic ligament, relaxin receptors have since been found to be widely distributed in many organs in both males and females. Acting through multiple pathways, including ...

Background: Certain cardiac-specific autoantibodies found in patients with dilated cardiomyopathy (DCM) play a role in mediating myocardial damage and fatal ventricular arrhythmias resulting in sudden cardiac death. Immunoadsorption therapy (IA) is one of the therapeutic tools to remove such autoantibodies. Clinical studies from Germany have shown that nonspecific IA using ...

Acute right ventricular (RV) failure is a frequent and serious clinical challenge in the intensive care unit. It is usually seen as a consequence of left ventricular failure, pulmonary embolism, pulmonary hypertension, sepsis, acute lung injury or after cardiothoracic surgery. The presence of acute RV failure not only carries substantial ...

We define cardiomyokines as heart-derived secreted proteins that affect cardiovascular function via autocrine, paracrine and/or endocrine mechanisms. The subject of this review is the cardiomyokine, mesencephalic astrocyte-derived neurotrophic factor (MANF). The expression of MANF is increased in the ischemic heart, in part, through activation of ER stress, a condition that ...

Oxidative stress is known to play a crucial role in the pathogenesis of heart failure (HF). We investigated whether urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), a product of oxidative DNA damage, is a clinically useful biomarker of the severity of chronic heart failure (CHF) and oxidative stress levels in failing hearts. We measured ...

Many are familiar with the parotid duct and the Danish physician/anatomist's name associated with it. However, most are unaware of Niels Stensen's life and his significant contributions to the early study of the heart. For example, he found that the heart is simply muscle and was the first to describe ...
