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

Summary

ORIGINS-VRCE-2 is an observational study aimed to assess how blood vessel forming stem cells from individuals without diabetes or a history of cardiovascular disease differ between individuals of South Asian and European ethnicities. The overarching objective of the study is to investigate whether differential vessel reparative stem cell populations and characteristics may underlie the elevated cardiovascular risk observed among South Asian individuals compared to individuals of European origins.

Eligibility

Inclusion Criteria:

1. Adults 18 years of age or older of South Asian origin or European origin as defined by the following: i. South Asian defined as any individual who identifies as Anglo-Indian, Bangladeshi, Bengali, Bhutanese, Goan, Gujarati, Indian, Jatt, Kashmiri, Maharashtrian, Malayali, Nepali, Pakistani, Punjabi, Sindhi, Sinhalese, Sri Lankan, Tamil, Telugu, or other South Asian origins. ii. European Origin defined as any individual who identifies as from western Europe, northern Europe, southern Europe, eastern Europe or other European origins.
2. Willing and able to provide written informed consent and comply with study requirements
3. Must fulfill the following exclusion criteria:

Exclusion Criteria:

1. No previous diagnosis of type 2 diabetes
2. Any previous CV events such as:

   1. Prior myocardial infarction
