Be seen today
Arrange prompt medical assessment if you are pregnant or recently gave birth and develop new breathlessness, increasing swelling, unusual exhaustion, palpitations, or difficulty breathing when lying flat.
These symptoms are not always caused by peripartum cardiomyopathy, but they deserve assessment.
If you have already been diagnosed, contact your care team promptly if symptoms return, swelling increases, your weight rises quickly from fluid, or you are struggling with ordinary activities.
