Vernakalant Versus Ibutilide In Recent-Onset Atrial Fibrillation

2015-06-10 01:53:23 | BioPortfolio


Atrial fibrillation is the most common cardiac arrhythmia and is expected to affect about 30 million North Americans and Europeans by 2050. Atrial fibrillation is associated with increased cardiovascular morbidity and mortality, with stroke being an especially important and potentially devastating complication. Many studies have investigated the efficacy of different drugs in converting atrial fibrillation to sinus rhythm. There are numerous randomized controlled trials that have tested the efficacy of agents against placebo and some trials that directly compared the efficacy of two or more different drugs. The class III antiarrhythmic drug Ibutilde is approved for the acute termination of atrial fibrillation and atrial flutter of recent onset and has been shown to be superior to sotalol and equivalent to flecainide in this indication. Recently, the relatively atrial selective antiarrhythmic agent vernakalant has been approved by the European Commission for the rapid conversion of recent onset AF to sinus rhythm in adults. The investigators hypothesize that the period of time needed for cardioversion to sinus rhythm and the efficacy of cardioversion within 90 minutes is different between vernakalant and ibutilide in patients with recent-onset atrial fibrillation.

Medical and Biotech [MESH] Definitions

Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).

Long-term changes in the electrophysiological parameters and/or anatomical structures of the HEART ATRIA that result from prolonged changes in atrial rate, often associated with ATRIAL FIBRILLATION or long periods of intense EXERCISE.

A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)

Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.

A THROMBIN inhibitor which acts by binding and blocking thrombogenic activity and the prevention of thrombus formation. It is used to reduce the risk of stroke and systemic EMBOLISM in patients with nonvalvular atrial fibrillation.
