Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - RAS-antagonist and beta-blocker up-to maximal dosages
Other interventions - RAS-antagonist and beta-blocker none or at stable dose

Experimental: Intensive therapy - RAS-antagonist and beta-blocker up-to maximal dosages as permitted and tolerated and following national guidelines.

Other: Conventional therapy - No RAS-antagonist and beta-blocker or at stable dose as per study entrance. Changes in RAS-antagonist or beta-blocker therapy are not allowed in the control group during the study phase.


Treatment: Drugs: RAS-antagonist and beta-blocker up-to maximal dosages
All patients have to be stable on their glucose lowering, lipid lowering and blood pressure lowering therapy at least for 3 months. RAS-antagonist and beta-blocker therapy at entrance is allowed. Patients receive a prescription and/or up-titration to maximum recommended or tolerated dose of RAS-antagonist and beta-blockers within three months of study entry. The Number of titration visits is up to the treating physician, but one visit should be performed at least at the end of titration.

Other interventions: RAS-antagonist and beta-blocker none or at stable dose
All patients have to be stable on their glucose lowering, lipid lowering and blood pressure lowering therapy at least for 3 months. RAS-antagonist and beta-blocker therapy at entrance is allowed. Changes in RAS-antagonist or beta-blocker therapy are not allowed in the control group during the study phase. If there is a vital indication for changes, this has to be argued and documented.

2. Patients already on maximum dose of RAS-antagonist or beta-blocker.
3. Creatinine > 2.5mg/dl.

6. Signs of cardiac disease in the ECG such as atrial fibrillation; ST-T abnormalities or any bundle branch block / higher degree atrioventricular (AV) block.
7. Abnormal echocardiography, defined as low ejection fraction < 50%; wall motion abnormalities suggesting coronary artery disease (CAD), significant valve dysfunction > grade I or other significant alteration.
8. Coronary artery disease, defined by a history of myocardial infarction, known coronary stenosis > 70% detected either by angiography or by CT-scan, significant defects in myocardial scintigraphy or positive stress-test echocardiography.
9. A disease other than T2DM lowering the patient's life expectancy to less than two years.
10. Chronic infections or malignancies.
11. Systemic treatment with corticosteroids.
12. Renal replacement therapy.
13. Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they meet the following definition of post-menopausal: 12 months of natural (spontaneous) amenorrhea or 6 months of spontaneous amenorrhea with serum Follicle Stimulating Hormone (FSH) levels > 40 mIU/m or 6 weeks post surgical bilateral oophorectomy with or without hysterectomy OR are using one or more of the following acceptable methods of contraception: surgical sterilization (e.g., bilateral tubal ligation), hormonal contraception (implantable, patch, and oral), and double-barrier methods (if accepted by local regulatory authority and ethics committee). Reliable contraception should be maintained throughout the study and for 7 days after study drug discontinuation.
14. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive Human Chorionic Gonadotropin (hCG) laboratory test (> 5 U/ml).
15. History of noncompliance to medical regimes and patients who are considered potentially unreliable.
16. Current double blind treatment in diabetic trials.
17. Participation in an investigational drug study at the time of enrollment or within the past 90 days.
