Table 4 Differences in vascular parameters between SLE patients with and without hypertension

From: Small artery elasticity is decreased in patients with systemic lupus erythematosus without increased intima media thickness

  CTL (n= 0) SLE - hypertension

SAE, ml/mmHg × 100 8.1 ± 2.6 6.4 ± 2.1* 6.4 ± 4.0

IMT, mm    
   Mean Maximum 0.72 (0.69 to 0.87) 0.70 (0.68 to 0.76) 0.73 (0.60 to 0.98)
   Mean 0.64 (0.59 to 0.70) 0.61 (0.58 to 0.65) 0.62 (0.55 to 0.81)
VCAM-1, ng/ml 371 ± 101 534 ± 159** 578 ± 182**

  1. Unless stated otherwise, data are expressed as mean ± standard deviation when normally distributed and as median (interquartile range) when non-normally distributed. AF, autofluorescence; AU, arbitrary units; CTL, healthy controls; MT, intima media thickness; SAE, small artery elasticity; SLE, SLE patients; TM, thrombomodulin; VCAM-1, vascular cell adhesion molecule-1; vWf, von Willebrand factor. Patients versus controls: * P ≤ 0.05, ** P ≤ 0.01. There were no significant differences between SLE patients without hypertension and SLE patients with hypertension.
