Abstract: | Opinion statement Both atrial and ventricular arrhythmias are very common in patients with congestive heart failure, and their presence is associated
with symptoms, significant morbidity, and mortality. Studies have attempted to determine the prognostic significance of atrial
and ventricular arrhythmias in patients with heart failure. Whether atrial fibrillation is an independent risk factor of mortality
remains controversial. The presence of ventricular arrhythmias in patients with ischemic cardiomyopathy identifies patients
at high risk for sudden death. However, in patients with nonischemic cardiomyopathy there is not a strong correlation between
ventricular arrhythmias and increased risk for sudden death. Multiple trials using antiarrhythmic drugs, pharmacologic therapy,
and implantable cardioverter defibrillators have been performed in an attempt to improve survival in patients 1) post-myocardial
infarction; 2) with congestive heart failure, with and without nonsustained ventricular tachycardia; and 3) with sustained
ventricular tachycardia and those who have survived an out-of-hospital cardiac arrest. The purpose of this article is to present
an overview of arrhythmias in patients with heart failure and discuss the prevalence, prognostic significance, complications,
mechanisms, and trials that have formed the current therapies presently used. |
