  Purpose

Increased levels of NT-proBNP are known to increase the risk of cardiac events in diabetic patients. The other way around, patients with normal values have an excellent prognosis on short-term. We intend in our study to proof the hypothesis, whether it is possible to decrease NT-proBNP levels by intensified cardiac prevention care We aim those patients, who already have elevated levels, although no history of a cardiac disease. This decrease in NT-proBNP should be translated consequently in a decrease in cardiac events

Primary Outcome Measures:
  • Reduction in cardiac events [ Time Frame: 2 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Decrease in NT-pro-BNP in the treatment arm [ Time Frame: 1 ] [ Designated as safety issue: No ]
  • Reduction in NT-proBNP [ Time Frame: 1 ] [ Designated as safety issue: No ]

Enrollment: 300
Study Start Date: November 2007
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Patient will receive cardiac therapy to decrease NT-proBNP levels. This will be primarily RAAS-Antagonists and Betablocker. Blood pressure will be lowered to target values. A decrease of NT-proBNP is also known form life-style changes. Thus the patient will be educated to be trained
 Drug: Telmisartan, Bisoprolol
Dosage will be given dependent on the NT-pro-BNP levels. Up-titration will be performed until values are decreased to 50% or below normal cut-point
Placebo Comparator: 2
Patients will be followed 2 years. Care will be given by the responsible unit ( Dept.of Endocrinology) as clinical appropriate. Event rates will be obtained. After one year NT-proBNP will be measured.
 Drug: placebo
no intervention
