The Impact of Frailty on Thrombosis of Elderly Patients With NVAF （FTE-NVAF）

The Impact of Frailty on Thrombosis of Elderly Patients With Non-valvular Atrial Fibrillation (NVAF).

This study aims to investigate the use of anticoagulants in elderly patients with non-valvular atrial fibrillation (NVAF) and the incidence of frailty in elderly patients with NVAF. After two years follow-up, we observe the incidence of thrombotic events and the influence of frailty on thrombotic events in elderly patients with NVAF.

Inclusion Criteria:

• ≥65yr
• Confirmed non-valvular atrial fibrillation (NVAF) diagnosis with ECG or Holter
• fulfilled CHA2DS2-VASc, HAS-BLED and Fried Scale
• patients agreed and provided informed consent

Exclusion Criteria:

• valvular atrial fibrillation
• cardiac surgery related atrial fibrillation
• acute disease related atrial fibrillation
• patients not fulfilled all the exam and text，or not accept the follow-up
