BACKGROUND Activation of the cholinergic anti-inflammatory pathway, which relies on the α7nAchR (alpha 7 nicotinic acetylcholine receptor), has been shown to decrease proinflammatory cytokines. This relieves inflammatory responses and improves the prognosis of patients with experimental sepsis, endotoxemia, ischemia/reperfusion injury, hemorrhagic shock,(More)
BACKGROUND Elevated heart rate is associated with increased cardiovascular morbidity. The selective I(f) current inhibitor ivabradine reduces heart rate without affecting cardiac contractility, and has been shown to be cardioprotective in the failing heart. Ivabradine also exerts some of its beneficial effects by decreasing cardiac proinflammatory cytokines(More)
Carvedilol, a nonselective beta-blocker with additional alpha1-adrenergic blocking and antioxidant properties, has been shown to be cardioprotective in experimental myocarditis. However, the antioxidative effects of carvedilol have not been investigated in the setting of acute viral myocarditis. Therefore, this study investigated whether carvedilol protects(More)
AIMS Although excessive sympathetic activation in viral myocarditis and the protective effects of sympathetic inhibition with β-blockers are clear, the effects of enhancing vagal tone on viral myocarditis remain unclear. In several models, vagus nerve activation with the α7 nicotinic acetylcholine receptor (α7-nAChR) agonists has been demonstrated to(More)
Carvedilol is a nonselective β-blocker with α1-adrenergic blocking and antioxidant properties. A number of preclinical experiments and clinical trials have demonstrated that carvedilol provides prominent benefit in heart failure. However, less research has been done in the area of animal models of viral myocarditis. This paper reviews the use of carvedilol(More)
Myocarditis, which is caused by viral infection, can lead to heart failure, malignant arrhythmias, and even sudden cardiac death in young patients. It is also one of the most important causes of dilated cardiomyopathy worldwide. Although remarkable advances in diagnosis and understanding of pathophysiological mechanisms of viral myocarditis have been gained(More)
The autonomic nervous system dysfunction with increased sympathetic activity and withdrawal of vagal activity may play an important role in the pathogenesis of viral myocarditis. The vagus nerve can modulate the immune response and control inflammation through a 'cholinergic anti-inflammatory pathway' dependent on the α7-nicotinic acetylcholine receptor(More)
BACKGROUND Platelets play a pivotal role in the pathogenesis of acute coronary syndrome (ACS) and acute and chronic complications following percutaneous coronary intervention (PCI). Platelet inhibition is a cornerstone in the management of these patients. Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder characterized by premature platelet(More)

BACKGROUND Development of experimental animal models has played an important role in understanding the mechanisms of cardiac memory. The purpose of this study was to evaluate a new canine model of cardiac memory using endocardial ventricular pacing via internal jugular vein. METHODS Twelve Beagle dogs underwent placement of a permanent ventricular(More)
