  Purpose

The efficacy of low dose aspirin appears to be substantially lower in diabetic patients, compared to patients without diabetes.

We will perform an observational study where we follow up patients with uncontrolled type 2 Diabetes Mellitus and low response to aspirin (Aspirin Resistance), during a period of 6 months in the diabetic clinic. Our hypothesis is that glucose control will improve the response to aspirin in those patients.


Condition
Diabetes Mellitus, Type II

Study Type: Observational

Primary Outcome Measures:
  • The outcome measure is the laboratory Aspirin Resistance. [ Time Frame: 3 and 6 months. ]

Secondary Outcome Measures:
  • To determine the incidence of laboratory aspirin resistance in type 2 DM in stable out-patients in the diabetic clinic, and possibly related factors. [ Time Frame: On screening visit. ]

Enrollment: 18
Study Start Date: November 2008
Study Completion Date: November 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
Observation
Type 2 diabetic patients with reduced laboratory response to aspirin.(Aspirin Resistance)and with HbA1c >8%.
