Abstract/OtherAbstract:
|
Atrial fibrillation (AF) is the most common clinical arrhythmia, and is difficult to treat. Current treatment strategies are far from optimal. Antiarrhythmic drug therapy to maintain sinus rhythm is limited by inadequate efficacy and potentially serious side effects. New areas of research include targeting the AF substrate and examining whether drugs can produce atrial structural and/or electrophysiological remodelling, and whether this results in a reduction in AF burden. There are two approaches to the treatment of AF. The first approach is cardioversion and treatment with antiarrhythmic drugs to maintain sinus rhythm. The other approach is the use of rate-controlling drugs allowing AF to persist. In both approaches, the use of anticoagulant drugs is recommended. There is an increasing interest in novel therapeutic approaches that target AF-substrate development. Recent trials suggest that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor II blockers (ARBs) may be useful, particularly in patients with left ventricular hypertrophy, hypertension, chronic heart failure and left ventricular dysfunction. While experimental studies have shown that the pathogenic structural and electrical remodelling of the atria are prevented by inhibition of angiotensin II, the clinical potential and mechanisms of this approach are still under active investigation. The present article will discuss information pertaining to the mechanism of action and clinical use of ACEIs and ARBs in AF. It will also review the current data on the use of ACEIs and ARBs in a high-risk group of AF patients (heart failure, hypertensive with left ventricular hypertrophy, and myocardial infarction), together with the potential benefit of this class type of pharmacological therapy in direct current cardioversion and after radiofrequency catheter ablation. |
