Brief Summary:
The aim of the study is to investigate the longterm impact on cardiovascular morbidity and mortality, relevant efficacy parameters (e.g., glycaemic parameters) and safety (e.g., weight and hypoglycaemia) of treatment with linagliptin in patients with type 2 diabetes at elevated cardiovascular risk receiving usual care, and compare outcome against glimepiride.

Primary Outcome Measures :
  1. Time to first occurrence of any of the following adjudicated components of the primary composite endpoint: CV death (including fatal stroke and fatal MI), non-fatal MI (excluding silent MI) or non-fatal stroke [ Time Frame: 432 weeks ]

Secondary Outcome Measures :
  1. Time to first occurrence of any of the following adjudicated components of CV death (including fatal stroke and fatal MI), non-fatal MI (excluding silent MI), non-fatal stroke or hospitalisation for unstable angina pectoris [ Time Frame: 432 weeks ]
  2. Proportion of patients on study treatment at study end, that at Final Visit maintain glycemic control (HbA1c <= 7.0%) without need for rescue medication, without any moderate/severe hypoglycaemic episodes and without > 2% weight gain (from V6 on) [ Time Frame: 432 weeks ]
  3. Occurence of any of the adjudicated components of the composite primary and composite first key secondary endpoint. [ Time Frame: 432 weeks ]
  4. Transitions in albuminuria classes between baseline and Final visit. [ Time Frame: 432 weeks ]
  5. Proportion of patients on study treatment at study end, that at Final Visit maintain glycaemic control (HbA1c <= 7.0%) without need for rescue medication and without > 2% weight gain (from V6 on) [ Time Frame: 432 weeks ]
  6. Occurence of and time to composite endpoint of all CEC confirmed adjudicated events [ Time Frame: 432 weeks ]
  7. Change from baseline to Final Visit in diabetes related laboratory parameters: HbA1c, fasting plasma glucose, Total cholesterol, LDL cholesterol, HDL cholesterol, Triglycerides, Creatinine, eGFR (MDRD formula), Urinary Albumin [ Time Frame: 432 weeks ]
