The impact of atrial fibrillation type on the risk of thromboembolism, mortality, and bleeding: a systematic review and meta-analysis.

Thromboembolic risk stratification schemes and clinical guidelines for atrial fibrillation (AF) regard risk as independent of classification into paroxysmal (PAF) and non-paroxysmal atrial fibrillation (NPAF). The aim of the current study was to conduct a systematic review evaluating the impact of AF type on thromboembolism, bleeding, and mortality.
