背景糖尿病在病程中通过内皮功能障碍损害微血管功能。由于心肌灌注对冷交感神经刺激的反应受到内皮相关因子的调节,因此可以通过冷加压试验(CPT)研究心肌灌注来无创观察早期内皮功能障碍。目的:应用磁共振CPT技术评价1型糖尿病患者的血管内皮功能。研究类型:前瞻性队列研究。对象:20例1型糖尿病患者和20例健康志愿者。场强/序列3 T,动态增强灌注(稳态自由进动)。评估静息和CPT下的绝对定量心肌灌注值。统计检验Kolmogorov-Smirnov检验确定结果的正态分布。独立样本的T检验。结果患者的平均心肌灌注在静息时为0. 68 cc/g/min,在CPT期间为0. 80 cc/g/min,在健康志愿者中分别为0. 81 cc/g/min和1. 36 cc/g/min。灌注值差异显着CPT(P< 0.01),但不是为静息条件(P= 0.06)。数据结论这项研究表明,内皮功能可能受损的1型糖尿病患者。这促进了内皮功能可能作为1型糖尿病患者冠状动脉疾病的早期生物标志物的论点,而这些患者仍然是临床症状。证据等级:2技术有效性:阶段3 J。Magn.

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.
