Introduction: Vernakalant is a new, safe and effective drug used intravenously. It has proven to be more rapid in converting recent onset atrial fibrillation (AF) to sinus rhythm compared to placebo, amiodarone, propafenone and flecainide in clinical studies with few patients. At present no study has been conducted comparing these three drugs with a more substantial number of patients. The aim of our study is to compare the time to conversion to sinus rhythm, hospital stay and adverse events between vernakalant versus flecainide and propafenone in patients with a recent-onset AF. Materials and Methods: 150 hemodynamically stable patients with recent onset AF without structural heart disease were prospectively included. A single oral dose of propafenone 600 mg was administered to 50 patients; 50 patients received intravenous vernakalant; and 50 patients received a single oral dose of flecainide 300 mg. Clinical and laboratory variables were recorded. Results: Baseline characteristics were similar in the three groups. Time to conversion to sinus rhythm was 12 minutes in the vernakalant group versus 151 minutes in the propafenone group and 162 minutes in flecainide group (p< 0.01). The hospital stay was 243 minutes in the vernakalant group versus 422 minutes in the propafenone group and 410 minutes in flecainide group (p< 0.01) (Figure 2). No adverse events were reported. Conclusion: The time to conversion to sinus rhythm and hospital stay were statistically shorter in vernakalant group compared to flecainide and to propafenone. There were no adverse events in the three groups. [ABSTRACT FROM AUTHOR]

Greater antithrombotic potency new antiplatelet agents have been added such as prasugrel (PR) and ticagrelor to the traditional use of clopidogrel (CL) in the treatment of acute coronary syndrome (ACS). This study was aimed at comparing the incidence of long term ischemic and hemorrhagic events in patients treated with CL or PR during hospitalization. Retrospective ACS data base analysis performed by our cardiology service was completed prospectively. There were consecutively included all patients with percutaneous coronary intervention (PCI) during hospitalization due to ACS from December 2011 thru December 2012. A total of 398 ACS patients who underwent PCI with stent implantation were recruited. No differences in cardiovascular related deaths were observed in both groups (PR 2.9% vs. CL 2.5%, p=0.48). PR group showed less re-infraction (1.9% vs. 6.8%, p=0.01) with more total bleedings (18.5% vs. 8.5%, p=0.001) and minor bleedings (12.4% vs. 3.4%, p<0.001) with no differences in major and life threatening bleedings (p=ns). Multivariate analysis showed that independent predictors of cardiovascular mortality were age (OR 1.08, CI 95% 1.02-1.16) and renal failure (OR 6.98, CI 95% 1.23-39.71). Independent predictors for total bleeding were age (OR 1.06, CI 95% 1.02-1.09),ST segment elevation myocardial infarction (OR 1.99, CI 95% 1.05-3.79), renal failure (OR 3.32, CI 95% 1.62-6.78) and prasugrel use (OR 3.97, CI 95% 1.87-8.41). Use of prasugrel, in the ACS that requires PCI with stent, is associated with a lower myocardial infarction a year after follow-up, and it also leads to an increase of milder hemorrhage. No significant differences were observed in the cardiovascular mortality of both groups.
