A woman's body undergoes various changes during pregnancy, some of which occur in the cardiovascular system. Here are the most prominent changes:
- Increase of blood volume between 30% and 50% compared to normal volume.
- Elevation of the heart rate to 15 beats per minute instead of 10 beats per minute.
- Lowering of blood pressure.
Therefore, if the woman's body does not support these changes, a cardiac decompensation can be generated, which can pose a risk in pregnancy. This should be especially considered for women with diseases of the circulatory system, i.e. affecting the heart and blood vessels.
