188 | Economic impact of the reduced incidence of atrial fibrillation in patients with heart failure treated with enalapril. | Atrial fibrillation (AF) in the setting of heart failure (HF) is linked to embolic stroke and exacerbation of HF. The rate of new-onset AF in patients with left ventricular dysfunction and mild to moderate HF enrolled in the SoLVD trials was significantly lower with enalapril than with placebo (5.4% vs 24% over 2.9 yea... |
189 | The Italian Registry for hypertrophic cardiomyopathy: a nationwide survey. | National registries are advocated as instrumental to the solution of rarity-related problems for patients with hypertrophic cardiomyopathy (HCM), including limited access to advanced treatment options. Thus, an Italian Registry for HCM was created to assess the clinical profile and the level of care nationwide of patie... |
190 | An algorithm for synchronization of in vivo electroporation with ECG. | The combined treatment of tumours in which delivery of a chemotherapeutic agent is followed by high voltage electroporation pulses has been termed electrochemotherapy. The electrochemotherapy of tumours located relatively close to the heart muscle can lead to fibrillation of the heart, especially if electroporation pul... |
191 | A quantitative analysis approach for cardiac arrhythmia classification using higher order spectral techniques. | Ventricular tachyarrhythmias, in particular ventricular fibrillation (VF), are the primary arrhythmic events in the majority of patients suffering from sudden cardiac death. Attention has focused upon these articular rhythms as it is recognized that prompt therapy can lead to a successful outcome. There has been consid... |
192 | The mitochondrial origin of postischemic arrhythmias. | Recovery of the mitochondrial inner membrane potential (DeltaPsi(m)) is a key determinant of postischemic functional recovery of the heart. Mitochondrial ROS-induced ROS release causes the collapse of DeltaPsi(m) and the destabilization of the action potential (AP) through a mechanism involving a mitochondrial inner me... |
193 | Usefulness of transoesophageal echocardiography before cardioversion in patients with atrial fibrillation and different anticoagulant regimens. | To evaluate the prevalence of atrial thrombi in patients with atrial fibrillation undergoing different anticoagulation regimens before cardioversion; to evaluate the usefulness of transoesophageal echocardiography (TOE) guided cardioversion to prevent thromboembolic complications; and to correlate the presence of atria... |
194 | Oxidative mediated lipid peroxidation recapitulates proarrhythmic effects on cardiac sodium channels. | Sudden cardiac death attributable to ventricular tachycardia/fibrillation (VF) remains a catastrophic outcome of myocardial ischemia and infarction. At the same time, conventional antagonist drugs targeting ion channels have yielded poor survival benefits. Although pharmacological and genetic models suggest an associat... |
195 | [Prognostic factors of survival in post-cardiopulmonary-cerebral resuscitation in general hospital]. | To assess clinical and demographic characteristics of patients who had cardiopulmonary resuscitation and identify short- and long-term survival prognostic factors.</AbstractText>Four hundred and fifty-two (452) resuscitated patients in general hospitals from Salvador were prospectively assessed through bivariate and st... |
196 | [Hypovolemic shock during surgery caused by a rectus sheath hematoma]. | Prophylactic treatment with low molecular weight heparins (LMWH) is currently widely used to prevent thromboembolic events. However, such treatment is not free of risk. Among the possible complications described is rectus sheath hematoma. We report the case of a patient undergoing surgery for a hypophysial adenoma appr... |
197 | [Cardiac arrest management in outpatient clinics: integration between hospital emergency care and the 118 emergency system in the model of Turin ASL 3]. | The incidence of sudden cardiac death ranges from 0.4 to 1.28 every 1000 inhabitants per year. Sudden cardiac death is responsible for about 10% of all deaths in Italy in 2000. It is unpredictable and is related to malignant ventricular arrhythmias that may be interrupted in more than 70% of cases. Survival rates gener... |
198 | Left atrial radiofrequency ablation during mitral valve surgery for continuous atrial fibrillation: a randomized controlled trial. | Although left atrial radiofrequency ablation (RFA) is increasingly used for the treatment of chronic atrial fibrillation during mitral valve surgery, its efficacy to restore sinus rhythm and any resulting benefits have not been examined in the context of an adequately powered randomized trial.</AbstractText>To determin... |
199 | Predictors of survival and hospital outcome of prehospital cardiac arrest in southern Taiwan. | Despite recent improvements in emergency care medicine, outcome for prehospital cardiac arrest patients remains poor in southern Taiwan due to lack of training and authorization of emergency medical technicians to perform advanced life support. The purpose of this study was to analyze the characteristics of these patie... |
