Abstract 201: Predictors of Stroke in Hospitalized Patients with Thrombotic Thrombocytopenic Purpura Poster Session II
Conclusion: Stroke develops in 8.16% of patients admitted with TTP. The independent predictors of stroke in this group of patients are age, white race, dyslipidemia, and AMI.

Incidence and type of arrhythmias recorded by one-month continuous ECG monitoring in stroke patients
CONCLUSIONSAF and other potentially relevant arrhythmias are frequent after stroke and easily detectable with one-month non-invasive continuous ECG monitoring. Patients with a parafibrillatory status could benefit from longer monitoring time to detect AF.

Detection of paroxysmal atrial fibrillation by prolonged electrocardiographic recording after ischaemic stroke in patients aged
CONCLUSION: This prospective observational study showed a low rate of paroxysmal AF among young patients presenting with stroke, on the basis of 21-day cardiac monitoring. This result highlights the need to identify patients who would benefit from such long monitoring. PMID: 25669959 [PubMed - as supplied by publisher]

Association of frequent premature ventricular complex & gt;10% and stroke-like symptoms without a prior diagnosis of stroke or transient ischemic attack
Conclusion High PVCs burdens (>10%) were associated with and stroke-like symptoms without a prior diagnosis of stroke or transient ischemic attack in the long-term follow up, suggesting more intensive medical therapy with close clinical follow-up will be required.

New-onset atrial fibrillation in patients with elevated troponin I levels in the acute phase of stroke
Troponin I (TnI) increase in the acute phase of stroke may be due to the presence of acute coronary syndrome (ACS), other medical conditions and/or neurogenic-induced cardiac injury, especially in stroke involving the insula of the right brain hemisphere [1]. In this case, damage to cardiomyocytes is probably due to the rapid release of catecholamines into the bloodstream as a result of sympathoadrenal activation [2,3]. The consequences of cardiac injury may include new-onset arrhythmias, such as multifocal ventricular beats, couplets and unsustained ventricular tachycardia or atrial fibrillation (AF) [3].

Drug-Induced Arrhythmias: A Scientific Statement From the American Heart Association.
Abstract Many widely used medications may cause or exacerbate a variety of arrhythmias. Numerous antiarrhythmic agents, antimicrobial drugs, psychotropic medications, and methadone, as well as a growing list of drugs from other therapeutic classes (neurological drugs, anticancer agents, and many others), can prolong the QT interval and provoke torsades de pointes. Perhaps less familiar to clinicians is the fact that drugs can also trigger other arrhythmias, including bradyarrhythmias, atrial fibrillation/atrial flutter, atrial tachycardia, atrioventricular nodal reentrant tachycardia, monomorphic ventricular tachy...

Patients treated with catheter ablation for ventricular tachycardia after an ICD shock have lower long-term rates of death and heart failure hospitalization than do patients treated with medical management only
Background: Ventricular arrhythmias in patients with implantable cardioverter-defibrillators (ICDs) adversely affect outcomes. Antiarrhythmic approaches to ventricular tachycardia (VT) have variable efficacy and may increase risk of ventricular arrhythmias, worsening cardiomyopathy, and death. Comparatively, VT ablation is an alternative approach that may favorably affect outcomes.Objective: To further explore the effect on long-term outcomes after catheter ablation of VT, we compared patients with history of ICD shocks who did not undergo ablation, patients with a history of ICD shocks that underwent ablation, and patient...

Patterns of incidence rates of cardiac complications in patients with congenital heart disease
ConclusionsCardiac complications are frequent in congenital heart disease. Apart from perioperative stroke and complete heart block, incidence rates are low in childhood but the incidence increases during adult life. These data underscore the need of life-long follow up and may help for better allocation of resources maintaining follow-up.

Are atrial high rate episodes (AHREs) a precursor to atrial fibrillation?
AbstractAtrial high rate episodes (AHREs), also termed, subclinical atrial tachyarrhythmias or subclinical atrial fibrillation (AF) are an important cardiovascular condition. Advancement in implantable cardiac devices such as pacemakers or internal cardiac defibrillators has enabled the continuous assessment of atrial tachyarrhythmias in patients with an atrial lead. Patients with device-detected AHREs are at an elevated risk of stroke and may have unmet anticoagulation needs. While the benefits of oral anticoagulation for stroke prevention in patients with clinical AF are well recognised, it is not known whether the same ...

Abstract 315: Feasibility of outpatient ambulatory ECG monitoring to screen for silent atrial fibrillation: Pilot Findings from Screening Trial for Undiagnosed Atrial Fibrillation (STUDY-AF) Poster Session III
CONCLUSION: Ambulatory screening of asymptomatic arrhythmias using the Zio® Patch is feasible; however the diagnostic yield for silent AF may be low, even among patients with established AF risk factors. Our study found a high prevalence of incidental asymptomatic SVT and NSVT. A larger trial with more targeted enrollment may be required to demonstrate the value of screening for AF. The impact of detecting incidental NSVT or SVT, which themselves could prompt evaluation and may be relevant to development of AF, requires further investigation.

Understanding Digoxin
 Most of us have heard of, or encountered a patient taking Digoxin at some point in our carreers. But, do we understand what it is and how it affects our patient?    Digoxin (Lanoxin), is a Cardiac Glycoside, derived from the foxglove plant, Digitalis. This medication is often seen in the pre-hospital setting, used for the treatment of:    Heart Failure (HF) with reduced Systolic Function   Atrial Fibrillation (AF) and Atrial Flutter (A-flutter) associated with Rapid Ventricular Response (RVR)   Cardiomyopathies   Often combined with Calcium and Beta Channel Blockers, Angiot...

Safety of Ventricular Tachycardia Ablation in Clinical Practice: Findings from 9699 Hospital Discharge Records Original Articles
Conclusions— VT ablation–associated AE rates in clinical practice are similar to those reported in the literature. Over time rates have increased as have the number of AE risk factors per patient. Ablations done electively and at hospitals with higher procedural volume are associated with lower incidence of AEs.
