Summary

This trial looks at the effects of increasing levels of beta-hydroxybutyrate on heart function in type 2 diabetic patients.

Who is the study for?
This trial is for adults aged 18-80 with Type 2 diabetes and heart failure (Class II-III NYHA) who have an ejection fraction below 50%. Participants should have a BMI of 23-38, stable blood pressure, and specific levels of HbA1c and NT-proBNP. Those on certain diabetes medications or with conditions that could risk safety or affect results can't join.
What is being tested?
The study tests how different levels of beta-hydroxy-butyrate (B-OH-B), a ketone body, affect heart muscle function and sugar uptake in the heart using advanced imaging techniques like cardiac MRI and PET scans in people with Type 2 diabetes suffering from heart failure.
What are the potential side effects?
While not explicitly listed, potential side effects may include reactions to substances used during MRI or PET scans, changes in blood sugar levels due to B-OH-B infusion, or discomfort at the infusion site.
