Heart failure living in pregnancy
Informed by recognized medical guidance
Overview
Heart failure means your heart is not pumping blood as well as it should. During pregnancy, your heart has to work harder to support both you and your baby. For some women, this extra strain can lead to heart failure, which is a serious condition that needs careful management.
Key facts
- Heart failure in pregnancy is rare but serious, requiring a team of specialists (cardiologist and high-risk obstetrician).
- Early diagnosis and treatment help protect both mother and baby.
- Many women with heart failure go on to have healthy pregnancies and babies.
- Regular monitoring and lifestyle changes are key to managing the condition.
No, heart failure is not common during pregnancy. However, it is a very serious condition that needs immediate medical attention if it occurs.
It can affect women who already have heart problems, or those who develop conditions like high blood pressure or cardiomyopathy (a weakened heart muscle) during or after pregnancy.
Symptoms
- Severe shortness of breath that does not improve when you sit up
- Chest pain or pressure that does not go away
- Fainting or feeling like you might pass out
- Coughing up pink, frothy mucus
- ⚠Worsening swelling or rapid weight gain (more than 1-2 kg per week)
- ⚠Inability to lie flat because of breathlessness
- ⚠Feeling extremely tired or weak that affects daily activities
Common symptoms
- Shortness of breath, especially when lying flat or with mild activity
- Persistent tiredness or weakness
- Swelling in the feet, ankles, or legs
- Rapid weight gain from fluid buildup
- Feeling like your heart is racing or pounding
Causes
Main causes
- Pre-existing heart conditions (e.g., valve problems, congenital heart defects)
- High blood pressure that develops during pregnancy (preeclampsia)
- Cardiomyopathy – a disease of the heart muscle that can appear during or after pregnancy
- Infections of the heart muscle (myocarditis)
Risk factors
- Previous heart failure or heart disease
- Chronic high blood pressure
- Diabetes
- Obesity
- Being older than 35
- Multiple pregnancies (twins, triplets)
When to see a doctor
See a doctor urgently if:
- If you have any of the emergency symptoms listed above, call your local emergency number immediately.
- If your symptoms are worsening and worrying you, see a doctor the same day.
Book a routine appointment if:
- All pregnant women should attend regular antenatal checkups.
- If you have a known heart condition, you should be under specialist care from early pregnancy.
Diagnosis
Your doctor will ask about your symptoms, listen to your heart and lungs, and check for swelling. They will refer you to a heart specialist (cardiologist) if needed.
Tests that may be done
- Echocardiogram – an ultrasound of your heart to see how well it pumps
- Blood tests – including a test for BNP (a substance released when the heart is strained)
- Electrocardiogram (ECG) – to check your heart’s rhythm
- Chest X-ray – to see if fluid is building up in your lungs (with protection for your baby)
What to expect at your appointment
You will be cared for by a team that includes a cardiologist and a specialist obstetrician. They will monitor you closely throughout your pregnancy and plan a safe delivery, usually in a hospital with special heart care.
Treatment
Treatment aims to manage symptoms, protect your heart, and keep your baby healthy. You and your baby will be monitored closely. Some women need to adjust their medicines or take new ones that are safe during pregnancy.
Self-care at home
- Weigh yourself daily and report rapid weight gain to your doctor
- Rest when you feel tired and avoid heavy physical activity
- Limit salt in your diet, as advised by your healthcare team
- Avoid alcohol and smoking
- Follow any fluid restrictions given by your doctor
Medical treatments
Your doctor may prescribe medicines that help your heart pump more effectively, remove excess fluid from your body, or control blood pressure. These medicines are chosen carefully to be as safe as possible for your baby. Never stop or change medications without talking to your healthcare provider.
When is surgery considered?
Surgery for heart failure is rarely needed during pregnancy. In some cases, after delivery, women may need a procedure to fix a heart valve or other structural problem. Your team will discuss this with you if it becomes necessary.
Living with this condition
Living with heart failure during pregnancy means having regular checkups and making some adjustments to your daily routine. You will likely need to see your doctor more often and plan for a hospital delivery. Rest is important, but gentle activity like walking may be okay – ask your team what is safe for you.
Lifestyle tips
- Rest when you feel short of breath or tired
- Avoid activities that make you push or strain hard
- Keep a record of your weight and any new symptoms
- Ask friends and family for help with heavy chores
- Plan ahead for your delivery – talk to your team about what to expect
Diet and exercise
Eat a balanced diet low in salt – your doctor may recommend a specific limit. Drink fluids as directed (sometimes you may need to limit them). Gentle exercise like walking or stretching may be safe, but always check with your healthcare team first. Avoid any exercise that leaves you breathless or exhausted.
Mental health and emotional wellbeing
Feeling worried, anxious, or sad is completely normal when dealing with a serious condition during pregnancy. It is important to talk about your feelings with your partner, family, or a counselor. If you feel very low or have thoughts of harming yourself, get help immediately – call your local emergency number or a crisis helpline. You are not alone.
Prevention
Not all cases of heart failure during pregnancy can be prevented, but managing your health before and during pregnancy can reduce the risk. If you have a known heart condition, see a cardiologist before becoming pregnant. Controlling high blood pressure and diabetes also helps.
Vaccines
It is safe and recommended to get the flu vaccine and the whooping cough vaccine during pregnancy. Talk to your doctor about which vaccines are right for you.
Screening programmes
If you have risk factors such as high blood pressure, a family history of heart problems, or previous pregnancy complications, your doctor may recommend extra monitoring, including early heart checkups.
Complications
If left untreated
- Worsening heart failure leading to severe breathing problems
- Preterm labor or early delivery
- Low birth weight for baby
- Need for emergency delivery or intensive care
Long-term outlook
With good medical care, many women with heart failure during pregnancy have successful outcomes and deliver healthy babies. After pregnancy, some women recover fully, while others need long-term management. Your healthcare team will help you through every step. There is a lot of hope and support available.
