[Carotid and brachial intima-media thickness of the allelic variants G894T and T-789C of eNOS in systemic sclerosis patients].

Objective: To evaluate comparatively the carotid intima media thickness index (IMT) and brachial index with Doppler ultrasound, and pulmonary artery pressure with echocardiography in allelic variation of G894T and T-789C eNOS (endothelial nitric oxide synthase) in patients with systemic sclerosis.

Methods: This is a cross-sectional study in patients with scleroderma. The inclusion criteria were: age 18-70 years, scleroderma diagnosed patients with a prior informed consent.
