Eligibility

Inclusion Criteria:

• Type 2 diabetes duration between 2 and 20 years
• Two or more components of metabolic syndrome:

• Or at least one of the following
• Carotid ultrasound showing an IMT > 1 mm and plaque of carotid artery or
• Left ventricular hypertrophy or
• Increased UACR in the absence of other renal diseases than diabetic nephropathy
• Increased hsCRP (> 2 mg/l but < 10 mg/l) at or within 6 months prior to screening and/or increased PAI 1 (> 15 ng/ml) at or within 6 months prior to screening (the historical hsCRP or PAI 1 value can be used only if the patient was in stable conditions regarding the concomitant diseases and statin therapy since the time point of measurement)
• Stable treatment with statins (if tolerated/clinically indicated)
• Age 40 - 75 years

Exclusion Criteria:

• Sustained uncontrolled hypertension: systolic blood pressure > 180 mmHg or diastolic blood pressure > 100 mmHg
• Hypersensitivity to the active substance or to any of the excipients
• Active clinically significant bleeding
• Lesion or condition, if considered to be a significant risk for major bleeding
• Concomitant treatment of acute coronary syndrome (ACS) with antiplatelet therapy in patients with a prior stroke or a transient ischemic attack (TIA)
• Hepatic disease associated with coagulopathy and clinically relevant bleeding risk including cirrhotic patients with Child Pugh B and C
• Chronic renal failure with eGFR < 15 ml/min (MDRD formula)
• Pregnant or breast-feeding woman and woman without adequate method of contraception.

Secondary	Change in Pulse Wave Velocity	Change in pulse wave velocity as a marker for arterial stiffness (measured by IEM Mobil-O-Graph)	Baseline to week 20
Secondary	Change in Skin Blood Flow	Change in skin blood flow for assessment of peripheral skin microcirculatory function (measured by laserdopplerfluxmetry; LDF)	Baseline to week 20
Secondary	Change in Skin Blood Flow	Change in skin blood flow for assessment of peripheral skin microcirculatory function (measured by laserdopplerfluxmetry; LDF)	Baseline to week 52
Secondary	Major Bleeding	Major bleeding defined as clinically overt and associated with one of the following: 1) reduction of hemoglobin level of 2 g/L or 2) required transfusion of at least 2 units of red cells or, involved a critical organ or was fatal, in accordance with the recommendation of the International Society on Thrombosis and Hemostasis (ISTH).
