Authors: Hakim SM, Elfawy DM, Elserwi HB, Saad MK Abstract INTRODUCTION: The aim of this review is to examine current evidence on value of new ST-segment or T-wave changes for prediction of major adverse cardiac events (MACE) after vascular surgery. EVIDENCE ACQUISITION: We searched PudMed, EMBASE and Cochrane Library databases for studies examining the relation between new ST-segment elevation or depression or T-wave inversion and MACE following vascular surgery. MACE was defined as fatal or non-fatal myocardial infarction, cardiac death, unstable angina, cardiac arrest, congestive heart failure, ischemic pulm...

AbstractAcute management of patients with ventricular arrhythmia (VA) is aimed at immediate VA termination if the patient is hemodynamically instable and early termination after initial diagnostic work-up if tolerated. Prolonged episodes of VA may lead to hemodynamic and metabolic decompensation and early resumption of normal ventricular activation is warranted. Termination is best performed by electrical cardioversion, anti-tachycardia pacing (if available, in cases with an implanted defibrillator [ICD]) or defibrillation. Antiarrhythmic drug treatment may lead to rhythm stabilization in cases of VA recurrence. Scrutinizi...

Left ventricular noncompaction (LVNC) is an increasingly recognised cardiomyopathy characterised by excessive trabeculation and deep intertrabecular recesses in direct communication with the left ventricular cavity. In LVNC, hypertrabeculation has been associated with heart failure, ventricular arrhythmia, and systemic thromboembolism. However, hypertrabeculation alone is not sufficient to define a subject as at risk for such complications and thus should not be sufficient to diagnose LVNC. Despite several studies having investigated parameters to predict adverse cardiovascular events, physicians have no effective tools to...

Conclusions: Preventive VT ablation before ICD implantation did not reduce mortality or hospitalization for arrhythmia or worsening heart failure during 1 year of follow-up when compared to the deferred ablation strategy.

Sudden cardiac death continues to be a major cause of death in patients with structural heart disease, and accounts for approximately 50% of total cardiovascular mortality. To prevent sudden cardiac death, current guidelines recommend that patients with heart failure and reduced left ventricular systolic function receive primary prevention cardioverter-defibrillator (ICD) devices, with supporting evidence from multiple clinical trials.1 For over two centuries, thyroid disease and cardiac arrhythmias have been shown to be closely associated.

Authors: Chen J, Xu S, Zhou W, Wu L, Wang L, Li W Abstract The aim of this study was to investigate the effect of exendin-4 (Ex-4) on ventricular arrhythmias and calcium sparks-mediated calcium leak in a myocardial infarction-heart failure model.We studied the influence of exendin-4 on ventricular arrhythmogenesis in a rat myocardial infarction-heart failure model. In vivo arrhythmia studies (electrocardiogram [ECG] telemetry studies), ex vivo arrhythmia studies calcium sparks tests, and analysis of total and phosphorylated ryanodine receptor (RyR) 2 and CaMK-II were carried out in sham group, myocardial infarction...

This study adds to the body of evidence in describing incidence and type of cardiac events experienced by an allogeneic and autologous HSCT population at one institution from 2012-2017. Sixty-five patients (9.8%) experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression analysis identified age (older), creatinine (higher) and history of coronary artery disease to significantly correlate with ris...

Conclusion: In this study, the significant difference between the electrocardiographic data of deceased and surviving dilated cardiomyopathy patients suggests that electrocardiographic data should be evaluated in detail in order to determine the low and high risk of mortality in patients with dilated cardiomyopathy.What is Known:•Previous studies on the relationship between limited electrocardiography data of adult patients diagnosed with DCM and mortality have been determinedWhat is New:•ECG data has not been investigated in such detail in child DCM patients,as in our study.

ConclusionsAppropriate therapies are frequent in patients with tetralogy of Fallot and ICDs, including in primary prevention. The relatively important proportion of ICD-related complication highlights the need for improving risk stratification in this population.

ConclusionIschemic and nonischemic CM confer similar risk of ventricular arrhythmia. This supports current guidelines regarding primary ‐prevention ICD. Short‐term survival is excellent but complications remain a problem.This article is protected by copyright. All rights reserved
