Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this mono-center,open,three-armes, controlled, randomized phase I study the progress of aortic valve calcification with and without vitamin K supplementation will be investgated. This will be done by means of measurements of concentrations from osteocalcine and MPG in blood serum, echocardiography, cardiac computed tomography and cardiac MRI

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients will be allocated to two groups with either

1. additional intake of 2 mg vitamin k1 daily
2. controll group without additional intake of Vitamin K

Treatment group a will include 100 patients, the controll group should include 100 patients. None of all patients should require renal dialysis.
