Peripartum cardiomyopathy: a comprehensive review

Area of Science:

• Cardiology
• Obstetrics
• Maternal Health

Background:

• Peripartum cardiomyopathy (PPCM) is a rare form of heart failure affecting women during late pregnancy or postpartum.
• It presents with left ventricular dysfunction and heart failure symptoms in previously healthy women.
• The exact cause of PPCM remains unknown, with potential contributing factors including viral, autoimmune, and idiopathic origins.

Purpose of the Study:

• To summarize the key aspects of peripartum cardiomyopathy (PPCM).
• To outline diagnostic criteria and identify risk factors for PPCM.
• To discuss treatment strategies and prognosis for affected women.

Main Methods:

• Review of existing literature on peripartum cardiomyopathy (PPCM).
• Analysis of diagnostic criteria, including timing of onset and exclusion of other cardiac conditions.
• Identification of associated risk factors such as advanced maternal age, multiparity, and race.

Main Results:

• PPCM incidence varies widely, from 1 in 1300 to 1 in 15,000 pregnancies.
• Diagnostic criteria involve heart failure onset in late pregnancy or early postpartum, with no identifiable cause.
• Identified risk factors include advanced maternal age, multiparity, African race, twinning, gestational hypertension, and long-term tocolysis.

Conclusions:

• Early diagnosis and prompt treatment of PPCM are crucial for optimizing outcomes.
• Treatment protocols for PPCM are similar to those for other forms of dilated cardiomyopathy.
• Approximately 50% of PPCM patients recover, while persistent cardiomyopathy after six months indicates a poor prognosis and reduced survival.
