Background : Siblings of  patients coronary artery disease are overlooked  in prevention of  non communicable diseases like coronary artery disease.

Objectives.  To study lipid profile of patients  of coronary artery disease and  their siblings to identify risk factors among  siblings like diabetes, hypertension, smoking, tobacco, alcohol.

Methodology: :– To study the lipid profile and other risk factors in 60 patients of coronary artery disease and their 120  siblings.

Results : Siblings of cases of coronary artery disease have abnormal lipid profile and risk factor like diabetes which is statistically significant when compared with the cases.

Conclusion: We conclude that there is significant abnormal lipid profile and other risk factors  among  siblings of  patients  coronary artery disease  when compared with the patients.
