Anticoagulation for heart failure in sinus rhythm: a Cochrane systematic review.

Patients with chronic heart failure (heart failure) are at risk of thromboembolic events, and coronary ischaemic events also contribute to the progression of heart failure. Long-term oral anticoagulation is established in certain groups, including patients with heart failure and atrial fibrillation, but there is wide variation in the use of oral anticoagulation in the broader heart failure population.
