  Purpose

The purpose of this study is to evaluate the effect of Vitamin D supplementation on cardiovascular disease and certain cells (T-regulatory cells) in the body that play a role in plaque formation in arteries. This study will determine the levels of Vitamin D and T-regulatory cells in subjects with coronary artery disease and if Vitamin D supplementation will affect future events such as heart attach and stroke.

Further study details as provided by Creighton University:

Primary Outcome Measures:
  • increase in T-regulatory Cells [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    We expect significant improvement in the suppressive capacity, with or without increase in the number, of circulating T-regs after vitamin D supplementation. This increase in T-regs function will correlate with improvement in clinical parameters.


Secondary Outcome Measures:
  • decrease pro-inflammatory cytokines & sTNFR1 and increase serum IL-10 [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    We also expect that vitamin D supplementation will decrease the levels of pro-inflammatory cytokines and sTNFR1 and increase the level of serum IL-10
