Heart health around pregnancy
Heart failure after pregnancy: what is peripartum cardiomyopathy?
It can be difficult to know which changes after having a baby need attention. Here is what this diagnosis means—and what to ask if it appears in your medical record.

Having symptoms now? Get care first.
Chest pain, trouble breathing or fainting during pregnancy or after birth need immediate medical care. Tell the team if you are pregnant or gave birth within the past year. For an emergency, call 911. Do not wait to finish a worksheet or for a routine appointment. Read the CDC’s full maternal warning signs.
What does peripartum cardiomyopathy mean?
Peripartum cardiomyopathy (PPCM), also called postpartum cardiomyopathy, is an uncommon form of heart failure near the end of pregnancy or in the months after delivery. The heart muscle becomes weak and pumps less effectively. A diagnosis requires assessment and exclusion of other causes. See the American Heart Association’s explanation.
Can it happen without a previous heart diagnosis?
Yes. PPCM can occur in someone without previously diagnosed heart disease. A new symptom deserves attention even when earlier visits were reassuring.
What symptoms can overlap with pregnancy or recovery?
Breathlessness, swelling and fatigue can overlap. New difficulty breathing, especially at rest or when lying flat, needs prompt assessment. Symptoms alone cannot tell you whether the cause is PPCM or another condition.
How is it evaluated?
An echocardiogram—an ultrasound of the heart—helps assess its pumping function. Clinicians may also use an examination, blood tests and other investigations. Your team decides which evaluation fits your symptoms.
After a diagnosis, leave with a clear plan.
If your team has diagnosed a heart condition, use their instructions as your starting point. You can bring these questions to a follow-up visit or ask for the answers in writing:
- What is the exact diagnosis in my record?
- What did my heart ultrasound show, and what does it mean for me?
- Which symptoms mean I should call you, and which need emergency care?
- Who is coordinating my heart care and my pregnancy or postpartum care?
- How does my plan account for pregnancy, breastfeeding or future pregnancy plans?
- What happens next, who do I contact, and when is my next visit?
Bring your discharge summary, current medicine list and any results you already have. If you are unsure of a term, copy it as written and ask your team to explain it.
