Atrial fibrillation: non cardiologist physicians approach

Atrial fibrillation is the most frequent arrhythmia. Its classification according to pattern and clinical type allows to decide the therapeutic strategy to use, that most include control of symptoms and prevention of cardioembolic events. The election of the treatment depends on the presence of triggering events, risk factors for thromboembolism, risk factors for bleeding, cardiac function, patient funcionality, medication costoefectiveness and health care access. The type of anticoagulant has to be supported on the type of atrial fibrillation and the presence of contraindications, documented ineffective anticoagulation or high risk of failure to warfarin. In case of contraindications for anticoagulation this could still be used in high bleeding risk patients, when risk factors are controllable or corrected; leaving left atrial appendage closure as an option for patients that remain in high risk for bleeding events
