Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 19 and older with type 2 diabetes and a carotid intima-media thickness of 1.0mm or more.

Probably not a fit

Patients currently using antithrombotic or anticoagulant medications other than aspirin may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of Clopidogrel and Cilostazol in preventing cardiovascular diseases among adults with type 2 diabetes who show early signs of atherosclerosis. Participants will undergo carotid ultrasound to measure carotid intima-media thickness, which helps assess their cardiovascular risk. The study aims to determine if these medications can inhibit the progression of carotid atherosclerosis in this high-risk population. By evaluating these treatments, the trial seeks to provide insights into their potential role in primary prevention strategies for cardiovascular complications in diabetics.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention strategies for cardiovascular diseases in patients with type 2 diabetes.

How similar studies have gone: While the use of Clopidogrel and Cilostazol has been established for symptom control, their role in primary prevention for this specific population is still being explored, making this approach relatively novel.
