  • Title: Macroangiopathy--does it play a role in young people?
    Author: Donaghue KC, Robinson J, McCredie R, Fung A, Silink M, Celermajer DS.
    Journal: Horm Res; 1998; 50 Suppl 1():38-40. PubMed ID: 9676996.
    Abstract:
    Using a novel ultrasound method, brachial artery endothelial and smooth muscle physiology were studied in 20 adolescents with IDDM and in 20 nondiabetic subjects matched for age (13-22 years), gender and vessel size. Endothelium-dependent dilatation (EDD) was assessed in response to flow (EDD) and endothelium-independent vasodilatation after sublingual glyceryl trinitrate (GTN). Both EDD and GTN were reduced in those with IDDM compared with controls: 5 vs. 9%, (p = 0.0002) and 14 vs. 21% (p = 0.002). Abnormal EDD was found in 12 IDDM adolescents (diabetes duration 3.3-14.9 years). The mean urinary albumin excretion rate of the diabetic group with abnormal EDD was 5.76 +/- 2.82 vs. 8.05 +/- 4.88 microg/min in those with normal EDD (p = 0.25). In the diabetic adolescents there was no significant correlation observed between the test for early large vessel disease, HbAlc and tests for diabetic microangiopathy.
