Modulation of the myocardial redox state by vagal nerve stimulation after experimental myocardial infarction.
AIMS Redox alteration plays a major role in the pathogenesis of heart failure (HF). Since vagal nerve stimulation (VNS) is known to improve survival and attenuate cardiac remodelling, we hypothesized that VNS may modulate the myocardial redox state. METHODS AND RESULTS Using a chronic HF mouse model, we applied VNS for 15 min and measured myocardial redox status using in vivo electron spin re...
متن کاملParasympathetic dysfunction and antiarrhythmic effect of vagal nerve stimulation following myocardial infarction.
Myocardial infarction causes sympathetic activation and parasympathetic dysfunction, which increase risk of sudden death due to ventricular arrhythmias. Mechanisms underlying parasympathetic dysfunction are unclear. The aim of this study was to delineate consequences of myocardial infarction on parasympathetic myocardial neurotransmitter levels and the function of parasympathetic cardiac gangli...
متن کاملVentricular ectopic rhythms following vagal stimulation in dogs with acute myocardial infarction.
SUMMARY Vagal stimulation inducing significant bradyeardia did not precipitate ventricular fibrillation in any of 34 dogs subjected to ligation of the left anterior descending coronary artery. Vagal stimulation , however, did result in two distinct types of ventricular arrhythmias occurring at different times following coronary occlusion. Within 3 hours, couplets and salvos were provoked which ...
متن کاملVagal stimulation and prevention of sudden death in conscious dogs with a healed myocardial infarction.
The interest for the antifibrillatory effect of vagal stimulation has been largely limited by the fact that this concept seemed restricted to acute experiments in anesthetized animals. To explore the potentially protective role of vagal stimulation in conscious animals we developed a chronically implantable device to be placed around the cervical right vagus. An anterior myocardial infarction w...
متن کاملSelf Care Behaviors in Patients after Myocardial Infarction
Introduction: One of determining and effective factors in health maintenance and prevention of progression of signs and symptoms of disease after heart attack is self care behaviors. The self care behaviors which can start after passing the acute period of disease has special importance in health maintanance and its recurrence. Objective: The aim of this study was to determine self care beha...
