[Lipoprotein (a), a new atherosclerotic risk factor. Blood levels in normal pregnancy].

Serum levels of lipoprotein (a), an important factor of atherosclerotic risk, in 32 patients during normal pregnancy and puerperium, were evaluated. Our results show a significant increase of the level of this lipoprotein (M = 20 mg/dl) versus controls (M = 16 mg/dl) during all periods of pregnancy, with a very significant increase at week 20th.
