New antiarrhythmic drugs for atrial fibrillation

Abstract

The development of new antiarrhythmic drugs is mainly aimed to treat atrial fibrillation, because of its prevalence and major consequences in terms cerebral vascular thrombosis. Specific blockade of I(Na) et I(K), even if efficacious, have previously shown to be proarrhythmogenic, with a global impairment of the cardiac patient's outcome. This lead to the development of new drugs, selectively targeting atrial currents such as I(Kur) ou I(KAch). The efficacy of amiodarone in treatment of atrial fibrillation has also yielded a whole array of new antiarrhythmic drugs targeting both these atrial currents but also sharing amiodarone pharmacodynamics properties. This renders the Vaughan-Williams classification ill-adapted for such drugs.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.
