Summary

Previous research has shown that Asian Indians are at relatively high risk for developing diabetes, heart problems and high blood pressure. The purpose of this study is to evaluate subclinical atherosclerosis (an early sign of heart disease) which may be associated with abnormalities like diabetes mellitus, hypertension (high blood pressure), high cholesterol and heart problems. Endothelium is the inner lining of your blood vessels. Endothelial dysfunction is found more in people with diabetes. In addition, high body mass index (BMI) is a strong risk factor for developing metabolic abnormalities like diabetes mellitus. This research study may provide information as to how useful endothelial dysfunction will be to detect people at risk of metabolic abnormalities and heart disease at an early stage. Two groups of subjects will be enrolled. Caucasians and Asian Indians There will be a total of 100 subjects participating in this study. Approximately 50 Caucasians and 50 Asian Indians will be enrolled. Caucasians will serve as the control group for this study.

Interventions

Type	Name	Description
PROCEDURE	Flow Mediated Doppler (FMD)	Non-invasive assessment of flow-mediated dilation (FMD) will be performed using brachial artery ultrasound.
DRUG	Nitroglycerin 0.4 mg sublingual	Nitroglycerin 0.4 mg (a small tablet that dissolves under the tongue) will be given to dilate the arteries. Images of the arm will be recorded via non-invasive flow-mediated doppler for 5 minutes to assess for endothelium dysfunction. as outlined above.
