Hepatocellular carcinoma (HCC) with metastasis to the heart is uncommon. We report a rare case of left atrial metastasis of HCC which was resected palliatively as a live-saving procedure with the use of cardiopulmonary bypass. Despite chemoembolization, which was undertaken 11 times, cardiac metastasis occurred. Moreover, the right and left ...

Sepsis-induced cardiac dysfunction is a frequent and severe complication of septic shock. The mechanisms responsible for its development are complex and intricate. Echocardiography is the best method to make the diagnosis of cardiac dysfunction. Biomarkers (B-type natriuretic peptides and cardiac troponins) can alert clinicians of the possibility of cardiac dysfunction. ...

High-resolution electrocardiography (ECG-CREM) is a method based on digital electrocardiography. In order to facilitate the interpretation of the Crem records the technique of vectorcardiography was used. In comparison the origin of the ventricular premature complexes (VPCs) could be estimated based on a standard 12-lead electrocardiogram. The aim of the study ...

Myocardial ischemia activates cardiac sympathetic afferents leading to chest pain and reflex cardiovascular responses. Brief myocardial ischemia leads to ATP release in the interstitial space. Furthermore, exogenous ATP and α,β-methylene ATP (α,β-meATP), a P2X receptor agonist, stimulate cutaneous group III and IV sensory nerve fibers. The present study tested the ...

The occurrence of peri-procedural myocardial ischemia with endoscopic retrograde cholangiopancreatography (ERCP) has been documented, but its significance remains controversial. This study aimed to investigate the incidence and risk factors of myocardial ischemia during ERCP procedures and to analyze the potential association between myocardial ischemia and post-ERCP complications. Ambulatory 24-h ST-segment ...

A 28-year-old woman was admitted to our institution, reporting progressive dyspnea, cough, and weight loss of 14 kg. Two-dimensional echocardiography revealed a left atrial mass, and cardiac magnetic resonance imaging showed localized involvement of the mass with adjacent structures. These clinical signs and radiographic images were highly suggestive of cardiac ...

Acute myocardial infarction is still one of the leading causes of death in the industrial nations. Even after successful revascularization, myocardial ischemia results in a loss of cardiomyocytes and scar formation. Embryonic EPCs (eEPCs), retroinfused into the ischemic region of the pig heart, provided rapid paracrine benefit to acute and ...

Ventricular arrhythmias are commonly observed in patients with ischemia. It is reported that the electrophysiological changes evoked by ischemia are greater in the epicardium than in the endocardium. To investigate the effects of this heterogeneity on transmural reentry, the computer simulation method is used. A two-dimensional model which can reproduce ...

BACKGROUND/AIM: Application of ischemic injury in a remote organ may provide protection of other tissues against ischemia. We hypothesized that ischemia in the rabbit hind limb protects against myocardial ischemia by increasing angiogenesis/arteriogenesis. MATERIALS AND METHODS: In the first experiment, severe limb ischemia (LI) was induced in 26 New Zealand ...

Acute coronary syndrome is sometimes accompanied by accelerated coagulability, lipid metabolism, and inflammatory responses, which are not attributable to the cardiac events alone. We hypothesized that the liver plays a pivotal role in the pathophysiology of acute coronary syndrome. We simultaneously analyzed the gene expression profiles of the liver and ...

Cardiac myxomas are histologically benign tumors but they may be lethal because of their strategic position. They have variable presentations and excellent prognosis after surgical excision. Left atrial myxomas may mimic mitral stenosis and is very rarely associated with pleural effusion. We presented a case of left atrial myxoma blocking ...

Although ventricular premature beats (VPBs) during acute regional ischemia have been linked to mechanical stretch of ischemic tissue, whether and how ischemia-induced mechanical dysfunction can induce VPBs and facilitate their degradation into reentrant arrhythmias has not been yet addressed. This study used a novel multiscale electromechanical model of the rabbit ...

The anti-anginal drug Ranolazine, a partial fatty acid oxidation (pFOX) inhibitor, is thought to modulate the metabolism during myocardial ischemia by activating pyruvate dehydrogenase activity to promote glucose oxidation. Ranolazine and its five principal metabolites: CVT-2512, CVT-2513, CVT-2514, CVT-2738 and CVT-4786, were synthesized. The effect of Ranolazine and its metabolites ...

OBJECTIVE: To determine whether the location of subcortical silent infarcts differs from that of symptomatic lacunar infarcts. METHODS: 32 silent infarcts and 59 acute lacunar infarcts located in the corona radiata were examined. The relative anterior-to-posterior locations of the silent infarcts in the corona radiata were compared with those of ...

Populations of intrathoracic extracardiac neurons transduce myocardial ischemia, thereby contributing to sympathetic control of regional cardiac indices during such pathology. Our objective was to determine whether electrical neuromodulation using spinal cord stimulation (SCS) modulates such local reflex control. In 10 anesthetized canines, middle cervical ganglion neurons were identified that transduce ...

During acute myocardial ischemia, reentrant episodes may lead to ventricular fibrillation (VF), giving rise to potentially mortal arrhythmias. VF has been traditionally related to dispersion of refractoriness and more recently to the source-sink relationship. Our goal is to theoretically investigate the relative role of dispersion of refractoriness and source-sink mismatch ...

Acute limb ischemia occurs when there is an abrupt interruption of blood flow to an extremity usually because of either embolic or thrombotic vascular occlusion. When profound ischemia ensues, this represents an emergency in which restoration of perfusion through early intervention can lead to limb salvage, whereas delay may result ...
