What this trial studies
This observational study aims to investigate the relationship between glycemic variability, insulin therapy modalities, and cardiovascular risk in individuals with type 1 diabetes. Participants will be followed for 10 years through clinical visits and online follow-ups, allowing researchers to gather data on cardiovascular events and other related health outcomes. The study will include a diverse range of recruiting sites, including university hospitals and private practices, to ensure a comprehensive understanding of the factors influencing cardiovascular mortality in this population.
Why it matters
Potential benefit: If successful, this study could identify new modifiable risk factors for cardiovascular diseases in patients with type 1 diabetes, potentially leading to improved management strategies.
How similar studies have gone: While there have been studies on cardiovascular risks in diabetes, this specific approach focusing on glycemic variability in a large cohort is relatively novel.
