E.1.1.1 | Medical condition in easily understood language |
Atrial fibrillation is a common type of cardiac rhythm disorder, which represents an important cause for stroke but also for myocardial infarction and heart muscle weakness (heart failure). |
La fibrillazione atriale è un diffuso disturbo del ritmo cardiaco, che rappresenta un’importante causa di ictus, ma anche di infarto del miocardio e debolezza del muscolo cardiaco. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To test whether an early, comprehensive, rhythm control therapy can prevent adverse cardiovascular outcomes in patients with recent-onset atrial fibrillation (AF) compared to usual care |
Il presente Studio mira a verificare se una terapia precoce di controllo del ritmo sia in grado di prevenire gravi complicanze cardiovascolari in pazienti con recente diagnosi di fibrillazione atriale (FA). Il trattamento precoce viene confrontato con la attuale terapia convenzionale (“usual care”). |

E.5 End points |
E.5.1 | Primary end point(s) |
A composite of cardiovascular death, stroke / transient ischemic attack (TIA), and hospitalization due to worsening of heart failure or due to acute coronary syndrome. The 1st co-primary outcome parameter is defined as the time to the first occurrence of a composite of the above mentioned components. The 2nd co-primary outcome is nights spent in hospital per year. |

Il 1° end-point co-primario è definito come periodo fino alla prima insorgenza dei sopra citati eventi. Il 2° end-point co-primario è il numero di notti trascorse in ospedale nell’anno. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
A first interim analysis is to be performed when the first 171 events in the 1st co-primary outcome have been observed. If the assumptions are met, this will happen 32 months after the first patient was randomized. The second interim analysis is to be performed when the first 343 events in the 1st co-primary outcome have been observed (approximately 47 months after the first patient was randomized). The third interim analysis is to be performed when the first 514 events have been observed (approximately 59 (11) months after the first (last) patient was randomized). The final analysis is to be performed when 685 events have been observed. If the assumptions are met, this will happen 72 (24) months after the first (last) patient was randomized. |
Una prima analisi ad interim dovrà essere eseguita all’avvenuta osservazione dei primi 171 eventi del primo end-point co-primario. Se le ipotesi sono confermate, ciò accadrà 32 mesi dopo la randomizzazione del primo paziente. La seconda analisi ad interim dovrà essere eseguita all’avvenuta osservazione dei primi 343 eventi del primo end-point co-primario (circa 47 mesi dopo la randomizzazione del primo paziente). La terza analisi ad interim dovrà essere eseguita all’avvenuta osservazione dei primi 514 eventi (circa 59 (11) mesi dopo la randomizzazione del primo (ultimo) paziente). L’analisi finale dovrà essere eseguita all’avvenuta osservazione di 685 eventi. Se le ipotesi sono confermate, ciò accadrà 72 (24) mesi dopo la randomizzazione del primo (ultimo) paziente. |
