Meta Analysis
Postoperative Atrial Fibrillation Following Noncardiac Surgery Increases Risk of Stroke.
New-onset postoperative atrial fibrillation is well recognized to be an adverse prognostic marker in patients undergoing noncardiac surgery. Whether postoperative atrial fibrillation confers an increased risk of stroke remains unclear. ⋯ New postoperative atrial fibrillation following noncardiac surgery was associated with a 2.5-fold increase in the risk of stroke. This risk was highest among patients undergoing nonthoracic noncardiac surgery. Given the documented efficacy of newer anticoagulants, randomized controlled trials are warranted to assess whether they can reduce the risk of stroke in these patients.

Ivabradine, a heart rate-slowing drug used to treat heart failure and (in Europe) angina, had varying impacts upon cardiovascular events in its 3 large outcome trials. Food and Drug Administration (FDA) analyses may explain the reasons for the variability. ⋯ Ivabradine used concomitantly with a loop diuretic has a beneficial impact upon cardiovascular death.
