Thromboembolic risk in the patient with heart failure
Opinion statement
Although heart failure is a procoagulant state, the incidence of arterial thromboembolism (peripheral arterial emboli and strokes) is relatively low in the outpatient setting and seems to be higher in those with concomitant atrial fibrillation or recent large anterior myocardial infarction, especially in the presence of a dyskinetic apex. Hospitalized heart failure patients, on the other hand, have an extremely high rate of deep venous thrombosis and pulmonary emboli. Outpatients with heart failure should receive anticoagulation only in the presence of atrial fibrillation or if they have experienced a prior embolic event. Patients with recent large anterior infarction or recent infarction with documented thrombus should be treated with anticoagulation for the initial 3 months after the infarct, whereas those with evidence of a mural thrombus should receive anticoagulation at least until the thrombus has resolved. Heart failure patients with ischemic cardiomyopathy should receive antiplatelet agents for the prevention of myocardial infarction, stroke, or death. Antiplatelet agents should not be prescribed for heart failure patients with nonischemic cardiomyopathy or without other evidence of atherosclerotic vascular disease. All hospitalized heart failure patients who are not taking oral anticoagulants should receive prophylaxis with low molecular weight heparins or factor Xa inhibitors.
