The MICRON Study - A Steno 1 Substudy

Multifactorial Intervention to Reduce Cardiac and Renal Oxygen Need in Type 1 Diabetes (the MICRON Study) - A Steno 1 Substudy


Sponsor

University of Aarhus

Enrollment

40 participants

Start Date

Oct 27, 2025

Study Type

OBSERVATIONAL

Conditions

Summary

The goal of this observational study is to compare cardiac and renal oxygen consumption among subjects with type 1 diabetes treated with either multifactorial intervention or according to the current standard care. Participants are recruited from a main study /the Steno1 study) responsible for the intervention. The main questions it aims to answer are if a multifactorial intervention in subjects with type 1 diabetes targeting cardiovascular and renal risk factors, will reduce cardiac and renal oxygen demand. Participants will undergo the following examinations at 0-month, 6-month, and 24-month after enrolling in the main study: * Measurement of cardiac and real oxygen consumption (\[11C\]acetate PET/CT-scan) * Measurement of kidney function (\[99mTc\]DTPA GFR measurement) * Measurement of markers of heart and kidney disease in blood and urine samples.
