Study summary

Aortic Stenosis is a common but fatal disease when it becomes symptomatic, specially if not treated. Until now surgery remains the only reliable and effective treatment.

In this study, the investigators will examine the effect of high dose of Menaquinone-7 (MK-7) supplementation (1000 mcg)/day on the progression of the aortic valve disease. The investigators hypothesize that MK-7 supplementation may slow or even reverse the progression of the disease process.

Read the detailed description

The study is a randomized clinical trial that will use Cardiac Echography and multi-detector computed tomography to compare the changes in the Aortic Valve Calcification Score (AVCS) over 3 years when using:

  1. 1000 mcg/d Vitamin K2 (menaquinone-7) + 5000 IU/d Vitamin D3
  2. 5000 IU/d Vitamin D3 as a control group

    Time frame: 3 years

  3. Evolution of the Aortic Valve Hemodynamic measured by echography: Change in V max in (m/sec)

    Time frame: 3 years

Secondary outcomes

  1. Activation of the MGP measured by the dp-uc MGP level which is a marker of vascular calcification.

Improvement of dyspnea according to the New York Heart Association Classification(NYHA) 4. Improvement of the quality of life of the patients( physical activity, mobility)

    Time frame: 3 years

  2. Reduction of the Aortic Valve calcification measured by CT Scan

    Reduction of the Aortic Valve Calcification Score (AVCS)
