Predictive factors of supraventricular arrhythmias after noncardiac thoracic surgery: a multicenter study.

Background: Supraventricular cardiac arrhythmias are the most common rhythm disturbances in patients following thoracic surgery. The purpose of our study was to determine which of the clinical parameters are the most valuable in predicting postoperative atrial fibrillation (AF) after lung surgery.

Methods: Retrospective analysis was carried out on 987 patients after noncardiac thoracic surgery to define the prevalence, associated risk factors, and clinical course of postoperative arrhythmias.

Relation between serum creatinine and postoperative results of open-heart surgery.

Objective: To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality.

Methods: This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations.
