INTRODUCTION: Current guidelines of chronic heart failure (CHF) do not recommend the use of oral anticoagulants (OAC) or antiplatelet therapy (APT). We performed a post-hoc analysis to evaluate the effect of the use of anti-thrombotic therapy with APT and OAC. PATIENTS AND METHODS: We examined 427 patients with advanced CHF, and assessed the effects of the use of APT or OAC at baseline on mortality. We employed a Cox-proportional hazard model to value the effects of APT or OAC use. RESULTS: After a mean follow-up of 3.4 years (range 2.0-5.4), 214 patients died (51%). Forty-one (41) percent (95%CI: 29-53%) of the patients on APT died, and 52% (47-57%) of the patients not on APT (P=0.07). Forty-eight (48) percent (42-54%) of the patients on OAC died, and 55% (46-63%) of the patients not on OAC (P=0.20). This effect of OAC was seen both in patients in sinus rhythm and in atrial fibrillation. After adjusting for important prognostic variables, such as age, LVEF, renal function, and NYHA class, both the use of APT (hazard ratio (HR) 0.62, 95% confidence interval (CI) 0.40-0.97; P=0.04) and the use of OAC (HR 0.60, 95%-CI 0.43-0.83; P<0.01) were related to an improved prognosis. CONCLUSION: This post-hoc analysis suggests that in CHF patients the use of APT or OAC is associated with a higher survival.
