Summary
Maternal cardiovascular modifications occur during pregnancy in order to create optimal conditions for the growth and the development of the fetus. As a matter of fact, it can be observed in deep structural and functional changes involving the entire cardiovascular and volume regulatory systems. The systemic vasodilation during the earliest stages of pregnancy will lead to the subsequent cardiovascular modifications: increase of plasma volume, stroke volume, and heart rate with a consequent augmentation of cardiac output. The failure of cardiovascular adaptation to pregnancy demands causes hypertensive disorders and fetal growth restriction.
Maternal hormones – first of all estrogens, progesterone, prolactin, relaxin and renin-angiotensin-aldosterone system – play a key role in the induction and the maintenance of the unique maternal hemodynamic profile during pregnancy. A lack or a reduction in the action of these hormones has significant consequences on the course of pregnancy.
