1. DEFINITION

Postpartum Myocardial Infarction (PPMI) is an acute ischemic injury of the myocardium occurring during the postpartum period due to interruption or severe reduction of coronary blood flow resulting in myocardial necrosis.

The postpartum period represents one of the highest-risk periods for pregnancy-associated myocardial infarction due to:

• Hypercoagulability
• Hemodynamic stress
• Endothelial dysfunction
• Coronary artery dissection
• Vasospasm
• Thrombotic events

Within the SCF framework, Postpartum Myocardial Infarction is classified as:

A maternal coronary perfusion collapse syndrome characterized by acute mismatch between myocardial oxygen demand and coronary blood supply resulting in ischemic myocardial injury, cardiomyocyte death, and systemic cardiovascular destabilization.

2. SCF ETIOPATHOGENIC CORE

Primary Disease Drivers

Coronary Vascular Injury

Including:

• Coronary artery dissection
• Endothelial disruption
• Plaque rupture
• Coronary thrombosis

Hypercoagulable State

Postpartum physiological changes include:

• Increased coagulation factors
• Reduced fibrinolysis
• Enhanced platelet activation

Result:

• Coronary thrombosis risk

Hemodynamic Stress

Postpartum alterations:

• Rapid fluid redistribution
• Increased cardiac workload
• Elevated ventricular wall stress

Hormonal Influence

Abrupt fluctuations in:

• Estrogen
• Progesterone
• Relaxin

Contribute to:

• Vascular fragility
• Coronary dissection susceptibility

Inflammatory Activation

Elevated:

• TNF-α
• IL-6
• CRP

Resulting in:

• Endothelial dysfunction
• Plaque instability
• Microvascular injury
