The effect of anticoagulants on clinical outcomes for patients with heart failure in sinus rhythm

One to two percent of the population in developed countries are affected by chronic heart failure and this increases to greater than 10% in those over 70 years old. Heart failure (HF) predisposes patients to thromboembolic events. Anticoagulants are often used to prevent thromboembolic events in specific patient populations, such as those with atrial fibrillation. Currently, no guidance exists on the long-term use of anticoagulants for patients with HF in sinus rhythm. This article critically appraises a systematic review which assesses whether the long-term use of oral anticoagulants reduces total mortality and stroke in patients with HF in sinus rhythm.
