Goal 3: Advance Translational Research

Arrhythmia Therapies Based on Understanding Mechanisms

There is a need to translate these new insights of genetic, molecular, cellular, and tissue arrhythmia mechanisms into the development of novel, safe, and new therapeutic interventions for the treatment and prevention of cardiac arrhythmias.

Is this idea a Compelling Question (CQ) or Critical Challenge (CC)? Critical Challenge (CC)

Details on the impact of addressing this CQ or CC

Reduced socioeconomic burden of cardiac arrhythmias. Development of new technologies and recognition of new arrhythmia mechanisms.

Feasibility and challenges of addressing this CQ or CC

Several studies have already recognized the unexpected antiarrhythmic effects of some therapies intended for other cardiovascular disease. For example statins, aldosterone blockers, and possibly some essential fatty acids may reduce arrhythmia burden in patients receiving these interventions. Clinical trials should be developed to demonstrate the efficacy of these interventions, and arrhythmia endpoints, including those for atrial fibrillation and sudden cardiac death, should be incorporated into other large clinical trials. Research into novel antiarrhythmic might focus on (a) drug development; (b) cell/gene-based therapy and tissue engineering; and (c) improvements in development and use of devices and ablation to prevent or inhibit arrhythmic electrical activity. Continued research might also focus on targeting of upstream regulatory cascades of ion channel expression and function. Continued antiarrhythmic strategies might include the exploration of novel delivery systems (e.g., utilizing advances in nanotechnology and microelectronics), biological pacemakers, AV node repair/bypass, and treatment and/or reversal of disease-induced myocardial remodeling and tachyarrhythmias. Evaluation of new therapies should include a cost analysis. Studies in both children and adults with congenital heart are needed. New interventions might include new pharmacologic approaches as well as advances in electrophysiologic imaging and improved approaches to ablation.
