Uninterrupted use of new anticoagulant reduces major bleeding events during atrial fibrillation ablation

Uninterrupted treatment with dabigatran, a non-vitamin K antagonist oral anticoagulant (NOACs), before, during and after ablation to treat atrial fibrillation significantly reduced the incidence of major bleeding events compared with uninterrupted use of the more established anticoagulant warfarin, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.

Liquid biopsies hold potential for detecting NSCLC EGFR mutations, predicting cancer recurrence

Three manuscripts published in the recent issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer, explored the versatility of liquid biopsies by identifying EGFR mutations using circulating tumor DNA (ctDNA) in urine and plasma and examining circulating tumor cells (CTCs) in plasma to predict the risk of lung cancer recurrence after surgical resection.

Catheter ablation more beneficial to heart failure patients than Amiodarone treatment

Among patients with heart failure and atrial fibrillation, those who underwent catheter ablation were less likely to die, be hospitalized or have recurrent atrial fibrillation than patients taking a heart rhythm regulating drug, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.
