Golden Hour Management of Peripartum Cardiomyopathy

Immediate Stabilization

The American College of Cardiology recommends immediate aggressive resuscitation with oxygen therapy, invasive hemodynamic monitoring, inotropic support, and rapid escalation to mechanical circulatory support if hemodynamically unstable in peripartum cardiomyopathy patients 1
Administer supplemental oxygen immediately to achieve arterial oxygen saturation ≥95% in patients with peripartum cardiomyopathy 2, 1
Apply non-invasive ventilation with PEEP 5-7.5 cmH2O if hypoxemia persists without cardiac arrest in peripartum cardiomyopathy patients 2, 1

Establish continuous invasive hemodynamic monitoring immediately upon stabilization in peripartum cardiomyopathy patients 1
Place continuous urinary catheter for strict fluid balance monitoring in peripartum cardiomyopathy patients 1
Administer intravenous furosemide 20-40 mg IV bolus for congestion and volume overload in peripartum cardiomyopathy patients 2
Use intravenous nitroglycerin 10-20 up to 200 μg/min for patients with systolic blood pressure >110 mmHg in peripartum cardiomyopathy 2

Initiate dobutamine or levosimendan if signs of hypoperfusion persist or congestion continues despite vasodilators and diuretics in peripartum cardiomyopathy patients 2, 1
Do not delay mechanical circulatory support if inotropes are required beyond the first hour in peripartum cardiomyopathy patients 1
Consider intra-aortic balloon pump counterpulsation as first-line mechanical support in peripartum cardiomyopathy patients 1

Initiate therapeutic anticoagulation with unfractionated heparin or low-molecular-weight heparin once post-delivery bleeding has stopped in peripartum cardiomyopathy patients 1
If still pregnant, use hydralazine combined with long-acting nitrates for afterload reduction, as ACE inhibitors and ARBs are absolutely contraindicated in peripartum cardiomyopathy patients 2
Initiate beta-1 selective beta-blockers (metoprolol, NOT atenolol) if hemodynamically stable in peripartum cardiomyopathy patients 3, 1, 4

Proceed with immediate delivery regardless of gestational age if the patient presents with advanced heart failure and hemodynamic instability in peripartum cardiomyopathy 1
Planned cesarean section is preferred for critically ill women requiring inotropic therapy or mechanical support in peripartum cardiomyopathy 2

Electrical cardioversion or defibrillation is recommended for pregnant women developing hemodynamically unstable ventricular tachycardia or ventricular fibrillation in peripartum cardiomyopathy 3

LV end-diastolic diameter >60 mm predicts poor recovery in peripartum cardiomyopathy patients 1
LVEF <30% indicates worse prognosis in peripartum cardiomyopathy patients 1
Urgent cardiac transplantation should be considered if weaning from mechanical circulatory support is unsuccessful in peripartum cardiomyopathy patients 1

Most pregnancy-related deaths occur in the first 4 weeks postpartum, requiring intensive monitoring during this period in peripartum cardiomyopathy patients 1
Supervise newborns for 24-48 hours after delivery to exclude hypoglycemia, bradycardia, and respiratory depression if mother received beta-blockers in peripartum cardiomyopathy 1
