Background:
Diabetic patients exhibit platelet hyperreactivity, which renders them resistant to antithrombotic treatments. We aimed to investigate the prevalence and predictors of aspirin resistance in diabetic patients.
Material And Methods:
A total of 93 diabetic and 37 non-diabetic participants were included into the study. Aspirin resistance was measured with a whole-blood desktop platelet function analyzer (PFA-100) with an epinephrine agonist.
Results:
Altogether 41.9% patients with DM were aspirin non-responders. Aspirin resistance was observed in 43.2% of non-diabetic patients (p = 0.89). Presence of diabetes mellitus had no effect on aspirin response (RR 0.95 (95% CI 0.44-2.05), p = 0.89) in the whole study population. Hypercholesterolemia was the only predictor of aspirin resistance in multivariate analysis in diabetic patients (RR 3.09 (95% CI 1.17-8.16), p = 0.023).
Conclusion:
The prevalence of aspirin resistance is comparable in diabetic and non-diabetic patients. Hypercholesterolemia is the only independent predictor of aspirin resistance in diabetic patients.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
