NCT01672567

Brief Summary

The purpose of this study is to determine the effects of daily consumption of eggs or egg substitute for 6 weeks on endothelial function and on cholesterol and lipoprotein levels in participants with clinically established coronary heart disease (CHD).

Outcome Measures

Primary Outcomes (1)

  • Endothelial Function Flow mediated dilatation (FMD) as the percent change in brachial artery diameter from pre-cuff inflation to 60 seconds post-cuff release.

    FMD will be measured as the percent change in brachial artery diameter from pre-cuff inflation to 60-seconds post-cuff release (upper arm cuff position). In addition to brachial diameter at 60 seconds post-cuff release, flow after cuff deflation within the first 15 seconds will be used as an indicator of stimulus strength, hyperemic flow being the stimulus for endothelial reactivity.

    6 weeks

Secondary Outcomes (2)

  • Fasting Lipid Panel - Total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglyceride level, cholesterol / high density lipoprotein cholesterol ratio

    6 weeks

  • 3-Day Food Diary
