BackgroundIn its course, diabetes impairs microvascular function through endothelial dysfunction. As the response of myocardial perfusion to sympathetic stimulation through cold is modulated by endothelium‐related factors, an incipient endothelial dysfunction might be observed noninvasively by investigation of myocardial perfusion with a cold pressor test (CPT). This approach has been used in clinical MRI previously.PurposeTo assess endothelial function of patients suffering from type 1 diabetes by MR CPT.Study TypeProspective cohort study.SubjectsTwenty type 1 diabetics and 20 healthy volunteers.Field Strength/Sequence3T, dynamic contrast enhanced perfusion (steady‐state free precession).AssessmentAbsolute quantitative myocardial perfusion values at rest and under CPT.Statistical TestsKolmogorov–Smirnov test to determine normal distribution of the results.T‐test for independent samples.ResultsPatients' mean myocardial perfusion was 0.68 cc/g/min at rest and 0.80 cc/g/min during CPT, respective values of 0.81 cc/g/min and 1.36 cc/g/min were found in healthy volunteers. Perfusion values differed significantly for CPT (P< 0.01) but not for resting conditions (P= 0.06).Data ConclusionThis study demonstrated that endothelial function might be impaired in type 1 diabetes patients. This fosters the thesis that endothelial function may serve as an early biomarker for coronary artery disease in patients with type 1 diabetes while these patients are still clinically asymptomatic.Level of Evidence:2Technical Efficacy:Stage 3J.
