Background

• Disease earlier than last month of pregnancy is likely the same process of HF

Evaluation

• Presentation similar to typical CHF
• 4 criteria needed to meet definition for PPCM:
  • Development of heart failure in last month of pregnancy or within 5mo of delivery
  • Absence of an identifiable cause for the heart failure
  • Absence of recognizable heart disease prior to the last month of pregnancy
  • LV systolic dysfunction, such as LVEF < 45%

Differential Diagnosis

• Respiratory tract infection
• PE
• MI
• Postpartum fluid overload

Cardiomyopathy

• Dilated cardiomyopathy
• Hypertrophic cardiomyopathy
• Restrictive cardiomyopathy
• Peripartum cardiomyopathy
• Takotsubo cardiomyopathy
• Arrhythmogenic right ventricular dysplasia

Postpartum Emergencies

• Amniotic fluid embolus
• Chorioamnionitis
• Eclampsia
• Postpartum endometritis
• Postpartum headache
• HELLP syndrome
• Postpartum hemorrhage
• Mastitis
• Peripartum cardiomyopathy
• Preeclampsia
• Retained products of conception
• Uterine rupture

Work-Up

1. ECG
2. CXR
3. CBC
4. Chemistry
5. TSH
6. TTE

Management

• Treat like usual heart failure (except avoid nitroprusside and ACEI)
