Abstract

Atrial fibrillation (AF) is the most common arrhythmia occurring in patients after coronary artery bypass surgery (CABG). The purpose of this study was to determine whether AF characteristics were independently associated with postoperative length of stay (LOS). Two hundred ninety consecutive post-CABG patients were examined through a detailed chart review. Baseline, intraoperative, and postoperative variables and the characteristics of AF were recorded. AF episodes were divided into single episodes lasting less than 24 hours (short-lived AF) and recurrent or prolonged >or=24 hours of AF (recurrent/prolonged AF). AF occurred in 94 (32.4%) patients. Twenty-six (27.7%) of AF patients had short-lived AF, and 68 (72.3%) of AF patients had recurrent/prolonged AF. Patients with recurrent/prolonged AF were older (P < 0.001) and more likely to have a history of prior AF (P < 0.001) relative to the other groups. Short-lived AF did not prolong LOS (7.2 +/- 2.1 days) relative to patients without AF (7.5 +/- 3.9 days), whereas recurrent/prolonged AF significantly prolonged LOS (10.4 +/- 6.1 days, P < 0.001). Multivariate analysis identified postoperative complications, recurrent/prolonged AF, age, and digoxin use as independent predictors ...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
