Atrial Fibrillation
Conditions
Brief summary
The purpose of this study is to evaluate the effectiveness of atorvastatin therapy (both during preoperative and postoperative period), as prophylaxis against postoperative atrial fibrillation after cardiac surgery, in a valve disease patient population (with or without associated coronary artery disease), with no previous history of atrial fibrillation and not receiving beta-blocking drugs.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with postoperative atrial fibrillation(atorvastatin and control groups) | Participants will be followed for the duration of hospital stay, an expected average of 10 days. | To evaluate the effectiveness of atorvastatin therapy (both during preoperative and postoperative period), as prophylaxis against postoperative atrial fibrillation after cardiac surgery, in a valve disease patient population (with or without associated coronary artery disease), with no previous history of atrial fibrillation and not receiving beta-blocking drugs or statins. |
Secondary
| Measure | Time frame |
|---|---|
| Changes in biochemical markers in both groups. | Participants will be followed for the duration of hospital stay, an expected average of 10 days. |
| Changes in echocardiographic parameters in both groups. | Participants will be followed for the duration of hospital stay, an expected average of 10 days. |
| Changes in inflammatory markers values during extracorporeal circulation, and postoperative atrial fibrillation. | Participants will be followed for the duration of hospital stay, an expected average of 10 days. |
| Clinical and hemodynamic consequences of postoperative atrial fibrillation after cardiac surgery. | Participants will be followed for the duration of hospital stay, an expected average of 10 days. |
| Prolongation of in-hospital and Intensive Care Unit (ICU) stay and the need for new drug or interventionism therapies, directly related to its appearance. | Participants will be followed for the duration of hospital day, an expected average of 10 days. |
| Frequency, duration, characteristics and risk factors for postoperative atrial fibrillation in patients with valve disease (without history of previous arrhythmia) undergoing cardiac surgery. | Participants will be followed for the duration of hospital stay, an expected average of 10 days. |
