Ion channel remodeling in heart failure modulates key cellular electrophysiological properties, predisposing to arrhythmias and sudden death. Heart failure induced ion channel dysfunction prolongs the action potential, increases spatio-temporal gradients of repolarization, promotes arrhythmogenic triggers and results in conduction abnormalities. Understanding fundamental ionic mechanisms of normal and abnormal electrogenesis is a key requirement for the development of effective and safe therapies. Elucidating the underlying molecular mechanisms and functional consequences of ion channel remodeling at the cellular and organ levels presents a unique opportunity for the development of novel pharmacological, device, gene, and cell based approaches for the treatment of arrhythmias in heart failure.
