Background: Whether large artery static and dynamic properties are different in type 2 diabetics with coronary or cerebrovascular disease (DM-CVD) as compared to patients free of clinical complications (DM) is debated.

Aim: To evaluate common carotid (CCA) IMT, local and aortic stiffness in DM-CVD as compared to DM and controls (CTRL).

Methods: thirty-five nondiabetic normotensive CTRL, 130 diabetics without complications (DM) and 25 diabetics with CAD and/or previous stroke/TIA (DM-CVD) (Tab 1) underwent radiofrequency (RF)-based ultrasound (QIMT® and QAS®, Esaote) of CCA, that provides automatic measurement of far-wall IMT, local stiffness (β-index) and contour wave analysis yielding local pulse pressure (PPc). Carotid-femoral pulse-wave velocity (PWV) was also measured (Complior).

Groups Age BMI Glycemia SBPb PPb
CTRL 56±8* 26±4* 88±10* 123±12* 46±8*
DM 62±8 29±5 146±42 136±18 57±16
DM-CVD 66±7 29±4 138±42 136±23 62±18

Results: Adjusting for sex, age and smoking habit, CTRL and diabetics differed significantly (p<0.05) in PWV (9.0±1.9 vs. 11.4±2.5 m/s), CCA IMT (619±146 vs. 736±169 μm) and PPc (37±9 vs. 46±14 mmHg), but not in β-index (10.1±2.9 vs. 12.5±4.9; p=0.23). Within diabetics, after adjustment for confounders, DM-CVD showed higher (p<at least 0.05) PPc but not CCA IMT, β-index and brachial PP (PPb) than DM (Tab 2).

Groups PWV IMT β-index SBPc PPc
CTRL 9.0±1.9* 619±146* 10.1±2.9* 115±12* 37±9*
DM 11.3±2.4 726±173 12.4±4.3 123±16 44±13°
DM-CVD 12.0±3.5 794±129 14.6±6.8 127±19 52±16
*:

p<0.05 in CTRL vs DM and DM-CVD;

°:

p< 0.05 in DM vs DM-CVD

Conclusions: central PP appears to be the only structural/functional large artery measure significantly different in diabetic patients with or without cardiovascular complications, despite similar glucose levels and BMI. Contour wave analysis by ultrasound provides additional information beyond IMT and local stiffness indices.
