- Dabigatran may be used as an alternative to warfarin in those wdo don't have: (I B)
- Prosthetic heart valve
- Hemodynamically significant valve disease
- Severe renal failure (creatinine clearance <15 mL/min) or
- Advanced liver disease (impaired baseline clotting function).
- If patient on anticoagulants with AF sustains stroke or systemic embolism, target INR may be raised to 3.0 - 3.5 (IIb C).
- Anticoagulation therapy can be interrupted for upto 1 week, if patients needs a procedure that carries a risk of bleeding (IIa C). For periods > 1 week unfractionated or low molecular weight heparin may be given IV (IIb C).
