NCT02621203
A multicentre, prospective, observational, hospital-based registry of patients with acute heart failure (AHF) those whose care was guided by a cardiologist in Turkey.
NCT02509754
Atrial fibrillation (AF) and congestive heart failure (CHF) are two epidemics that share several physiopathological links. CHF patients present a significantly increased risk of developing AF and the related detrimental hemodynamic effects are even more relevant than in patients without CHF. Within CHF patients rate control is the most widely used strategy to manage AF, having proved non-inferior to rhythm control strategies. However, by this strategy, the hemodynamic effects of AF persist, not contrasting the natural evolution towards progressive left ventricular (LV) function, cardiac output , and symptoms worsening. Rhythm control strategy, instead, has shown, in the general population, advantages over rate control concerning survival, quality of life and thromboembolic events. The main limitation is that antiarrhythmic therapy used to achieve this goal has several side effects, and that transcatheter AF ablation has been assessed only in modest sample size studies. Available literature focusing on a direct comparison between two specific management strategies in patients with CHF and AF is limited to a small randomized study comparing pulmonary veins isolation to AV node ablation and biventricular PM implantation (PABA-CHF study). Additional indirect evidences may derive from meta-analyses of observational studies. The investigators therefore designed this multicenter, randomized controlled trial aiming to assess if, in recently diagnosed (less than 6 months) and optimally treated CHF patients with impaired LV function, AF catheter ablation is effective in improving LV function and clinical functional class, potentially driving to a reduction of device implantations (ICD/CRTs).
