Late Effects Assessment Programme: Pregnancy and heart health

Check this important information if you have had anthracycline chemotherapy or radiation to your chest and are planning a family. You might like to first read Late Effects Assessment Programme: Your heart.

Tell your maternity carers about the treatment you received.

Key points to remember

  • if you had anthracyclines or high dose chest irradiation, make sure your maternity carers know what treatment you received
  • also, make sure your maternity carers have a copy of your 'health passport'
  • most young women do not have any problems but your health care team may need to check your heart during pregnancy

What happens to the heart during pregnancy?

Make sure your maternity carers have a copy of your 'health passport'.

During pregnancy and labour the heart needs to work much harder. The blood volume increases by 30 to 50 percent and the amount pumped by the heart every minute (cardiac output) increases by up to 30 to 40 percent. The size of the heart increases to cope with the extra demand on it. Even if your heart has been fine, this is a time when problems could develop.

If you had anthracyclines or high dose chest irradiation, make sure your maternity carers know what treatment you received. Also, make sure they have a copy of your 'health passport'. Most young women do not have any problems but your health care team may need to check your heart during pregnancy.

Current recommendations

Echocardiogram

If you have had an echocardiogram before becoming pregnant and this was normal, no further routine scans are necessary. If not, then you should have an echocardiogram during the first 3 months. If you develop shortness of breath, unexpected tiredness (fatigue), blood pressure changes or ankle swelling, then you need another echocardiogram. It may be necessary for you to see the high-risk maternity team.

If you had very high dose anthracycline or chest irradiation, your health provider may also recommend that you have repeat echocardiograms in pregnancy.

Specialised care

Your health care team may advise you to include a medical doctor (obstetrician or GP) in your care. This can be either instead of, or together with, a midwife. Your GP or Late Effects Assessment Programme (LEAP) team can refer you to the local hospital maternity service where specialised care is free.

Hospital birth

Your health care team may suggest a hospital birth rather than a home birth if they think you are high risk.

Checking your heart during each pregnancy

Even if your heart is fine during your first pregnancy, checking your heart is still important during any further pregnancies.
