Based on the two major r and omised trials ( HELAS 2006 ; WASH 2004 ) , there is no convincing evidence that oral anticoagulant therapy modifies mortality or vascular events in patients with heart failure and sinus rhythm .
Although oral anticoagulation is indicated in certain groups of patients with heart failure ( for example those with atrial fibrillation ) , the available data does not support the routine use of anticoagulation in heart failure patients who remain in sinus rhythm
BACKGROUND Patients with chronic heart failure ( heart failure ) are at risk of thromboembolic events , including stroke , pulmonary embolism and peripheral arterial embolism , whilst coronary ischaemic events also contribute to the progression of heart failure .
Long-term oral anticoagulation is established in certain patient groups , including patients with heart failure and atrial fibrillation , but there is wide variation in the indications and use of oral anticoagulation in the broader heart failure population .
OBJECTIVES To determine whether long-term oral anticoagulation reduces total deaths , cardiovascular deaths and major thromboembolic events in patients with heart failure .
Antithrombotic therapy is associated with better survival in patients with severe heart failure and left ventricular systolic dysfunction (EPICAL study).
BACKGROUND In patients with congestive heart failure ( CHF ) , clinical trials have demonstrated the benefit of a number of drugs on morbidity and mortality . Nevertheless so far , there is no published controlled study of long-term antithrombotic therapy in patients with CHF . The aim of this work was to identify the relationship between cardiovascular drug use , especially antithrombotic therapy , and survival of CHF patients in current clinical practice , using an observational , population -based data base . METHODS The EPICAL study ( Epidémiologie de l'Insuffisance Cardiaque Avancée en Lorraine ) has identified prospect ively all patients with severe CHF in the community of Lorraine . Inclusion criteria were age 20 - 80 years in 1994 , at least one hospitalisation for cardiac decompensation , NYHA III/IV HF , ventricular ejection fraction < or = 30 % or cardiothoracic index > or = 60 % and arterial hypotension or peripheral and /or pulmonary oedema . A total of 417 consecutive patients surviving at hospital discharge were included in the data base . The average follow-up period was 5 years . Univariate Cox models were used to test the relationship of baseline biological and clinical factors to survival .  Cardiovascular drug prescriptions were tested in a multivariate Cox model adjusted by other known predictive factors . RESULTS Duration of disease > 1 year , renal failure , serum sodium > or = 138 mmol/l , old age , serious comorbidity , previous decompensation , high doses of furosemide and vasodilators use were independently associated with poor prognosis at 1 and 5 years . Oral anticoagulants , aspirin , lipid lowering drugs and beta-blockers use were associated with better survival . There was no interaction between aspirin and angiotensin converting enzyme inhibitor use on survival . CONCLUSION Antithrombotic therapy was associated with a better long-term survival in our study population of severe CHF . These results together with other previously published circumstantial evidence urge for a prospect i ve , controlled and r and omised trial specifically design ed to evaluate optimal oral anticoagulants and aspirin in patients with congestive heart failure
