The GISSI-AF Investigators: Valsartan for Avoidance of Recurrent Atrial Fibrillation Atrial fibrillation is the most common cardiac arrhythmia. 1-5 Antiarrhythmic medications have just moderate efficacy in preventing recurrences of atrial fibrillation and sometimes may cause serious adverse reactions.6-8 Ablation is an expensive procedure, and accepted indications are small kjøpe cialis billig .9,10 Thus, new approaches to the administration of atrial fibrillation continue being the subject of interest and investigation. Some studies have shown that the recurrence of atrial fibrillation after cardioversion may be partially related to a biologic phenomenon known as remodeling, in which the electrical, mechanical, and structural properties of atrial cells and cardiac cells are progressively and irreversibly altered, creating a far more favorable substrate for atrial fibrillation.14-17 Several clinical studies have suggested that ACE inhibitors or ARBs may have an advantageous effect on either new-onset atrial fibrillation or recurrent atrial fibrillation .

Data were obtained from all Planned Parenthood wellness centers offering medical abortion. For today’s analyses, we excluded affiliates that did not offer medical abortion in every four intervals and centers that in Period 2 provided program antibiotics to just a subgroup of customers . Statistical Analysis We calculated 95 percent self-confidence intervals for rates as exact binomial self-confidence intervals. Fisher’s exact test was used to assess the significance of distinctions in proportions. We tested for differences in relative declines in rates between your two groups utilizing a test for homogeneity of risk ratios. Two-sided P values of less than 0.05 were considered to indicate statistical significance. Calculations were performed by using Cytel Studio software, version 8 , or Stata 10 software .
