Angina living in pregnancy
Informed by recognized medical guidance
Overview
Angina is chest pain or discomfort that happens when your heart doesn't get enough oxygen-rich blood. During pregnancy, your heart works harder to support you and your baby, which can sometimes trigger angina, especially if you already have a heart condition or other risk factors.
Key facts
- Angina is not a disease itself but a symptom of an underlying heart issue, like narrowed arteries.
- In pregnancy, angina may be caused by increased blood volume and strain on the heart.
- Pregnancy-related conditions like preeclampsia or anemia can also contribute to angina.
Angina is not common during pregnancy, but it can occur, especially in women who already have heart disease or risk factors like high blood pressure, diabetes, or smoking.
It affects pregnant women, particularly those with pre-existing heart conditions, older age, obesity, or conditions like preeclampsia. It can also occur in women who develop pregnancy-related anemia or have a history of heart problems.
Symptoms
- Chest pain that lasts more than a few minutes or is severe
- Pain that spreads to arms, back, neck, or jaw
- Shortness of breath that does not go away with rest
- Feeling faint, lightheaded, or breaking out in a cold sweat
- ⚠New or worsening chest pain, especially if it happens with minimal activity or at rest
- ⚠Chest pain that comes and goes but worries you
- ⚠Swelling in your legs or sudden weight gain (possible preeclampsia)
Common symptoms
- Chest pain or pressure, often behind the breastbone
- Pain that may spread to the arms, neck, jaw, or back
- Shortness of breath
- Fatigue or dizziness
Causes
Main causes
- Reduced blood flow to the heart muscle due to narrowed or blocked arteries
- Increased workload on the heart during pregnancy, especially in the second and third trimesters
- Pregnancy conditions like preeclampsia (high blood pressure) or anemia (low red blood cells)
Risk factors
- Pre-existing heart disease (e.g., coronary artery disease, valve problems)
- High blood pressure or diabetes before or during pregnancy
- Smoking, obesity, or high cholesterol
- Being over 35 years old
- History of preeclampsia in a previous pregnancy
When to see a doctor
See a doctor urgently if:
- If you have any chest pain that is new, severe, or does not go away
- If you also have shortness of breath, dizziness, or nausea
Book a routine appointment if:
- Discuss any history of heart disease or risk factors with your obstetrician at your first prenatal visit
- If you have occasional mild chest discomfort that goes away with rest, mention it at your next appointment
Diagnosis
Your doctor will ask about your symptoms, medical history, and risk factors. They will check your blood pressure, listen to your heart, and may order tests to see how your heart is working.
Tests that may be done
- Electrocardiogram (ECG) – quick test to check heart rhythm and electrical activity
- Blood tests – to check for heart damage, anemia, or signs of preeclampsia
- Echocardiogram – an ultrasound of your heart to see structure and function
- Fetal monitoring – to check your baby's well-being
What to expect at your appointment
Your healthcare team will work together (obstetrician, cardiologist, midwife) to monitor both your heart and your baby. Some tests may need to be adjusted during pregnancy, but they are generally safe. You may be asked to keep a symptom diary and have more frequent prenatal visits.
Treatment
Treatment focuses on keeping you and your baby safe. It may include lifestyle changes, medications that are safe in pregnancy, and close monitoring. The goal is to relieve symptoms, prevent complications, and manage any underlying conditions.
Self-care at home
- Rest when you feel chest pain or shortness of breath
- Avoid heavy lifting or sudden strenuous activity
- Manage stress with relaxation techniques like deep breathing
- Stay hydrated and eat small, frequent meals
Medical treatments
Your doctor may prescribe medications to improve blood flow or lower blood pressure, such as nitrates or beta-blockers, that are considered safe during pregnancy. They may also treat underlying conditions like anemia with iron supplements or manage preeclampsia with blood pressure control. Never take any medication without your doctor's advice.
When is surgery considered?
Surgery for angina is very rare during pregnancy. In severe cases where medications aren't enough, a procedure like angioplasty (opening a blocked artery) may be considered, but only after carefully weighing risks to you and your baby. Your doctor will discuss all options.
Living with this condition
Pay attention to how you feel. If chest pain occurs with activity, slow down and rest. Keep your prenatal appointments and follow your care plan. Monitor your blood pressure at home if advised. Know the signs of emergency and who to call.
Lifestyle tips
- Eat a heart-healthy diet with fruits, vegetables, whole grains, and lean protein
- Stay active with mild activities like walking or prenatal yoga (get your doctor's okay first)
- Avoid smoking, alcohol, and recreational drugs
- Get enough sleep and manage stress
Diet and exercise
Focus on balanced meals low in salt and unhealthy fats. Light exercise, such as walking for 20–30 minutes most days, can improve circulation and reduce stress. Always check with your doctor before starting or changing any exercise routine during pregnancy.
Mental health and emotional wellbeing
Living with angina during pregnancy can be stressful and frightening. It's normal to feel anxious or worried about your health and your baby's. Talk to your healthcare team about your feelings. They can connect you with support services.
Prevention
You can lower your risk by managing any existing health conditions before pregnancy, eating well, staying active, and not smoking. If you have heart disease, work with your doctor to plan your pregnancy carefully. Not all cases can be prevented, especially if you have a pre-existing condition.
Screening programmes
If you have risk factors for heart disease, your doctor may recommend a heart health evaluation before or early in pregnancy. Regular prenatal care includes blood pressure checks and urine tests to screen for preeclampsia.
Complications
If left untreated
- Heart attack (myocardial infarction) – damage to heart muscle
- Heart failure – heart struggles to pump enough blood
- Preeclampsia or eclampsia – severe high blood pressure that can harm you and your baby
- Poor fetal growth or premature birth
Long-term outlook
With good medical care and close monitoring, most women with angina during pregnancy can deliver a healthy baby. Your healthcare team will create a safe plan for labor and delivery. Taking care of your heart now also benefits your long-term health after pregnancy.
