Genotype looms large in risk for post-op arrhythmia

Postoperative atrial fibrillation (PoAF), a form of arrhythmia, complicates 20-40% of cardiac surgical procedures and 10–20% of non-cardiac thoracic operations, cropping up two to four days after surgery to pose risk of stroke, heart attack, mortality, longer hospital stays and greater cost.

VUMC testing device to reduce stroke risk in arrhythmia patients

Vanderbilt University Medical Center (VUMC) is the first in the state to enroll patients in a clinical trial testing the effectiveness of the newest implantable device used to reduce stroke risk in patients with non-valvular atrial fibrillation (AF), the most common form of arrhythmia.
