Mean Platelet Volume and Cardiac Surgery-Associated Atrial Fibrillation

Atrial fibrillation after cardiac surgery.

trial fibrillation (AF) after cardiac surgery is a major cause of morbidity and mortality, and it has been reported that the rate of occurrence is 18–40%.1–5 Various causes have been studied, including advanced age, body mass index, obesity, left atrial dimensions, cardiac dysfunction, chronic respiratory failure, renal dysfunction, fluid balance, preoperative medications, inflammation, and fib...

Mean platelet volume is associated with the presence of left atrial stasis in patients with non-valvular atrial fibrillation

BACKGROUND Mean platelet volume has been associated with stroke in patients with atrial fibrillation. However, its role as a predictor of left atrial stasis, assessed by transesophageal echocardiography, in patients with non-valvular atrial fibrillation has not yet been clarified. METHODS Single center cross-sectional study comprising 427 patients admitted to the emergency department due to s...

Increased Mean Platelet Volume is Associated with Left Atrial Spontaneous Echo Contrast in Patients with Atrial Fibrillation

Objective: The accurate underlying pathogenic mechanism behind spontaneous echo contrast (SEC) is complex and poorly understood. The aim of this study is to characterize the relationship between mean platelet volume (MPV) and left atrium SEC. Material and methods: We screened retrospectively the records of 172 patients with AF in whom transesophageal echocardiography was performed. Patients wer...

Left atrial volume predicts the risk of atrial fibrillation after cardiac surgery: a prospective study.

OBJECTIVES This study sought to identify preoperative predictors of postoperative atrial fibrillation (POAF) among patients undergoing cardiac surgery. BACKGROUND Postoperative atrial fibrillation is frequent after cardiac surgery and is associated with increased morbidity, mortality, prolonged hospital stay, and increased costs. Left atrial volume (LAV), a marker of chronically elevated left...
