Assessment of the Cardioankle Vascular Index in Pregnant Women Complicated with Hypertensive Disorders

الملخص EN

It was previously reported that the brachial-ankle pulse wave velocity (baPWV) is elevated in preeclamptic women.

However, baPWV is strongly affected by blood pressure.

Recently, a new index of vascular stiffness, the cardioankle vascular index (CAVI), was developed.

CAVI is thought to be an index independent of blood pressure.

We assessed CAVI in normotensive and hypertensive pregnant women.

We studied a total of 109 Japanese women consisting of 23 nonpregnant healthy women (group A), 45 normotensive pregnant women (group B), 28 pregnant women complicated with established preeclampsia (group C), and 13 pregnant women with chronic hypertension (group D).

The subject remained supine while the blood pressure, baPWV, and CAVI were recorded.

No significant difference in baPWV was present between groups C and D, but the difference in CAVI was significantly high in group D.

We believe that we can distinguish the vessel structural change between chronic hypertension and preeclampsia through simultaneous baPWV and CAVI measurements.
