Circulating Vascular Regenerative Cell Exhaustion in Individuals Without Type 2 Diabetes Who Are of South Asian or European Origins

This study is comparing the health of blood vessel repair cells in people of South Asian origin versus European origin who do not have type 2 diabetes. The goal is to understand whether South Asians — who are known to have higher rates of cardiovascular disease — show early signs of vascular cell exhaustion even before diabetes develops. **You may be eligible if...** - You are 18 or older - You identify as being of South Asian origin (including Indian, Pakistani, Bangladeshi, Sri Lankan, and other South Asian backgrounds) OR of European origin - You do not have type 2 diabetes - You are willing and able to provide informed consent and follow the study procedures **You may NOT be eligible if...** - You have been diagnosed with type 2 diabetes - You do not meet other screening criteria (such as having certain health conditions that could affect vascular cell health) Talk to your doctor to see if this trial is right for you.
