Risk and benefit: The beneficial effect of anticoagulant treatment is well
established by numerous therapeutic trials demonstrating its usefulness in
two main indications (venous thromboembolism and complete arrhythmia due to
atrial fibrillation) in selected populations. Very few trials have been sp
ecifically conducted in elderly subjects and the increased risk of thrombos
is and anticoagulant related bleeding cannot be used to extrapolate the res
ults to elderly subjects. For this reason, a careful assessment of the init
ial risk and expected benefit must be made for each individual patient usin
g a validated and systematic global evaluation system adapted for elderly s
ubjects in order to better discern the indications and the risk of hemorrha
ge.
Perspectives: The development of anticoagulation clinics, based on the meth
od initiated by Professor Boneu at Toulouse, together with clinical trials
designed to produce results transposable to the diverse and complex geriatr
ic population, and finally the development of new oral compounds not requir
ing laboratory tests under the same conditions should help reduce the thera
peutic risk for an equivalent benefit.
