Welcome to the ASCEND study website. ASCEND is a clinical trial which aimed to find out whether aspirin and/or omega-3 fatty acids (fish oils) reduced the risk of heart attacks and strokes in people with diabetes who did not already have any existing problems with their heart or blood circulation, when they started the study. 

We would like to say a big "Thank you!" to all our ASCEND participants for your ongoing support for the study.

The main trial has now ended. Participants stopped taking study treatment in 2017, and results were reported in 2018. ASCEND will continue to collect information on health outcomes by obtaining routinely collected data via central data registries and NHS sources. See the long-term study section for more information about this long-term follow-up, and our Privacy Notice for information on how we use participant data.
