Abstract

Background Cardiovascular disease is the leading cause of mortality in type 1 diabetics (T1D). T1D patients have increased coronary artery calcification (CAC) compared to nondiabetics. We hypothesize that myocardial blood flow (MBF) reserve can be measured in long-standing T1D patients using regadenoson stress cardiac magnetic resonance (CMR) perfusion imaging and is a marker of extensive atherosclerotic disease associated with CAC.

Highlights

  • Cardiovascular disease is the leading cause of mortality in type 1 diabetics (T1D)

  • We hypothesize that myocardial blood flow (MBF) reserve can be measured in long-standing T1D patients using regadenoson stress cardiac magnetic resonance (CMR) perfusion imaging and is a marker of extensive atherosclerotic disease associated with CAC

  • RABIT1D is a sub-study of the Coronary Artery Calcification in Type 1 Diabetics (CACTI) study that established a cohort of 656 T1D patients and 764 non-diabetic controls that was followed for progression of CAC over 6 years with electron beam tomography
