Cardiovascular risk factors in healthy women with previous small for gestational age infants.

AIM: To investigate whether healthy women with a previous pregnancy complicated by a small for gestational age (SGA) infant have normal endothelial function, carbohydrate and lipid metabolism, and normal inflammation parameters.

MATERIAL AND

METHODS

Brachial artery flow-mediated dilatation (FMD, endothelium-dependent) was measured in 16 subjects with previous SGA, and in 15 controls (CTR) with previous normal pregnancies. Lipid panel, glucose, insulin, tumor necrosis factor alpha (TNF-alpha), soluble intercellular adhesion molecule-1 (s-ICAM), soluble vascular (s-VCAM-1) adhesion molecule-1 (s-VCAM-1), and androgens were also measured.

RESULTS

FMD was reduced in women with previous SGA compared to controls (P < 0.0001). SGA women showed increased insulin resistance (P < 0.0001), s-ICAM-1 (P = 0.008), TNF-alpha (P = 0.02), testosterone (P = 0.03), and diastolic blood pressure (P = 0.01) than CTR.

CONCLUSION

Endothelial dysfunction, reduced insulin sensitivity and subclinical inflammation are present in otherwise healthy women with previous SGA. These abnormalities show that the presence of a SGA infant in the obstetric history should be considered as a risk factor for cardiovascular disease later in life.
