ClinicalTrials.gov Identifier: NCT00343499
(Inability to recruit)
24 week, single center, prospective, randomized, double-blind treatment study of valsartan (80 mg/bid, increased to 160 mg/bid) or placebo in addition to other general medical therapy in patients with persistent atrial fibrillation (AF) undergoing electrical cardioversion to restore normal sinus rhythm (SR).
Condition or disease
To evaluate the efficacy of valsartan, added to standard AF therapy, to maintain sinus rhythm and extend the interval to first AF recurrence after cardioversion.Evaluate the efficacy of valsartan, begun prior to cardioversion, on the difficulty (number and total energy of CV attempts), the net rate of cardioversion (to SR for >10 minutes), and early AF recurrence rate (within 24 hours)

18 Years and older (Adult, Senior)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
The patient (male or non-pregnant female) must be >18 years of age
Have ECG documented AF at the time of enrollment into the study
Female patients of childbearing potential must have a documented negative pregnancy test during the index hospitalization.
The patient or legally authorized representative willing to give written informed consent, prior to the procedure, using the ICF approved by the UCR Institutional Review Board. Surrogate consent must be given per CV Research SOP.
Have a serum potassium level between 3.5 and 5.5 meq/L

Women of childbearing potential must be using adequate measures of contraception (as determined by the Investigator) to avoid pregnancy and should be highly unlikely to conceive during the study period. Women of childbearing potential must have a negative pregnancy test at screen.
