OVERVIEW

Aspirin, a medicine that reduces platelet activity, is recommended for people with diabetes who already have heart disease in order to reduce their likelihood of having a further heart attack or stroke. Whether aspirin reduces the risk of a first heart attack or a first stroke in people with diabetes is unclear.

This study, conducted in people with diabetes who did not have heart disease, compared the ability of aspirin 100 mg once daily, aspirin 200 mg once daily or aspirin 100 mg twice daily to reduce platelet activity.

design

Double-blind, randomised, three-way cross-over, interventional clinical trial.

 

RESULTS

Aspirin 100mg twice-daily reduced platelet reactivity more effectively than 100mg once-daily, and numerically more than 200mg once-daily. Clinical outcome trials evaluating primary cardiovascular prevention with aspirin may need to consider using more frequent doses. The published results are available here.
