About this study
The aims of this investigation are:
To assess the predictive value (and accuracy) of clinical and physiologic preoperative variables in identifying patients at risk for the development of new-onset atrial arrhythmia after cardiac surgery.
To assess the feasibility of a physiological risk model based on clinical and echocardiographic indexes to predict post-operative AF.
To assess the role of prophylactic agents in the prevention of new-onset postoperative POAF
To assess the economic impact of new-onset postoperative AF:
Length of hospital stay (will be measured as fractions of days)
Hospital cost (will be measured in standardized dollars)
Resource utilization (will be measured by resource-based relative-value units)
To assess the outcome of patients who develop early atrial fibrillation following cardiac surgery:
