Study information
Scientific title
What is the most cost effective anti-thrombotic strategy to reduce mortality in heart failure? The WASH Study
Acronym
WASH Study
Study hypothesis
Heart failure is common and causes appreciable morbidity and mortality. It is associated with recurrent myocardial infarcts, strokes, and other thrombo-embolic events. For these reasons anti-thrombotic therapy using aspirin or warfarin is seen as normal clinical practice. However aspirin has a number of side-effects, and warfarin requires regular blood tests, increasing its cost and inconvenience for patients. Thus using these agents should be justified by clinical benefit. The aim of this study was to see if it would be possible to organise a trial of aspirin, warfarin, and no anti-thrombotic treatment.
