Aspirin 80 mg EC Tab: Participants will receive a 7 day supply of Aspirin 80 mg EC Tab and will be instructed to take the drug at the same time every day for 7 days.
Study summary
This phase 1 study will include patients suffering from type 2 diabetes mellitus and will study their response to enteric coated aspirin at a dose of 80 mg per day for a 7-day period. The aims are to determine the feasibility of a phase 2 larger scale trial, and to characterize the prevalence of incomplete platelet inhibition after exposure to EC aspirin at doses of 80 mg once daily. Platelet function will be assessed at baseline and a day 7.

Inclusion Criteria:

* Fasting Plasma Glucose (FPG) ≥ 126 mg/dL (7.0 mmol/L) (fasting is defined as no caloric intake for at least 8h);

4. Willing to attend all study visits.
Exclusion Criteria:
1. Definitive indication for aspirin, including any evidence of atherosclerotic disease, previous or current;
2. Known hypersensitivity to aspirin;
3. High-risk GI bleeding features, such as known H. pylori infection, past or present ulcer, history of bleeding from the GI tract;
4. Bleeding diathesis;
5. History of hematological malignancy or myelodysplasia;
6. Platelet count or hemoglobin levels outside of the normal reference range;
7. Planned major surgical procedure within 30 days of enrolment;
8. Chronic inflammatory disease requiring regular anti-inflammatory treatment;

Primary outcome measure(s)
Incomplete platelet aggregation inhibition by aspirin at 7 days. — 7 days. Incomplete platelet aggregation inhibition will be defined as ≥ 20% of residual platelet aggregation in response to arachidonic acid at a concentration of 1mM, measured by LTA (Light Transmission Aggregometry).
