Abstract

Objectives This study was designed to explore the relationships of early diabetic microangiopathy to alterations of cardiac sympathetic tone and myocardial blood flow (MBF) regulation in subjects with stable type 1 diabetes.Background In diabetes, augmented cardiac sympathetic tone and abnormal MBF regulation may predispose to myocardial injury and enhanced cardiac risk.Methods Subject groups comprised healthy controls (C) (n = 10), healthy diabetic subjects (DC) (n = 12), and diabetic subjects with very early diabetic microangiopathy (DMA+) (n = 16). [(11)C]meta-hydroxyephedrine ([(11)C]HED) and positron emission tomography (PET) were used to explore left ventricular (LV) sympathetic integrity and [(13)N]ammonia-PET to assess MBF regulation in response to cold pressor testing (CPT) and adenosine infusion.Results Deficits of LV [(11)C]HED retention were extensive and global in the DMA+ subjects (36 +/- 31% vs. 1 +/- 1% in DC subjects; p < 0.01) despite preserved autonomic reflex tests. On CPT, plasma norepinephrine excursions were two-fold greater than in C and DC subjects (p < 0.05), and basal LV blood flow decreased (-12%, p < 0.05) in DMA+ but not in C or DC subjects (+45% and +51%, respectively). On adenosine infusion, compared with C subjects, MBF reserve decreased by approximately 45% (p < 0.05) in DMA+ subjects. Diastolic dysfunction was detected by two-dimensional echocardiography in 5 of 8 and 0 of 8 consecutively tested DMA+ and DC subjects, respectively.Conclusions Augmented cardiac sympathetic tone and responsiveness and impaired myocardial perfusion may contribute to myocardial injury in diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
