Ventricular Arrhythmias and Myocardial Revascularization
نویسنده
چکیده
Ventricular arrhythmias are closely associated with myocardial ischemia and its sequelae. Acute ischemia frequently leads to ventricular fibrillation (Vfib) and to sudden cardiac death. As well, chronic ischemia, if presented as ischemic cardiomyopathy with restricted left ventricular function, is prone to the risk of Vfib. In contrast, scar formation after myocardial infarction leads to reentry circuits as an origin of ventricular tachycardia (Vt).

INTRODUCTION AND OBJECTIVES The influence of coronary artery revascularization on the control of ventricular arrhythmias in patients with chronic myocardial infarction is uncertain. However, ablation of the arrhythmogenic circuit in these patients by aneurysm resection is useful for controlling ventricular arrhythmias. We made a prospective analysis of our clinical strategy in patients who were...

Introduction: Inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. The aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ACE) inhibitor, ramiprilat and angiotensin type 1 (AT1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat mo...

OBJECTIVES The objective of this study was to analyze the influence of coronary artery revascularization in patients with ventricular arrhythmias. BACKGROUND Coronary artery revascularization is an effective treatment for myocardial ischemia; however, its effect on ventricular arrhythmias not related to an acute ischemic event has not been carefully studied. METHODS Sixty-four patients (58 ...

Background & Aims: This study was carried out to assess the effect of opium addiction on the incidence of different types of arrhythmias after acute myocardial infarction (AMI). Methods: The study population consisted of 200 patients with first AMI admitted within 6 hours of the onset of chest pain to the coronary care units (CCU) of two hospitals affiliated to Kerman University of Medical Scie...

The purpose of this EP wire is to examine clinical practice in the field of screening of patients of risk of ventricular arrhythmias and/or sudden cardiac death (SCD) in European countries. A systematic screening programme existed in the majority of centres and was organized by a multidisciplinary dedicated team or by an activity programme of implantable cardioverter-defibrillator (ICD) or hear...
