Myocardial infarction during pregnancy: a review

Area of Science:

• Cardiology
• Obstetrics
• Maternal Health

Background:

• Myocardial infarction (MI) during pregnancy is a rare but serious complication.
• Review of global literature and case studies on pregnancy-associated MI.

Observation:

• Maternal mortality is highest when MI occurs late in pregnancy.
• Delivery within two weeks of MI and reinfarction during labor increase mortality risk.
• Cardiovascular stress intensifies in late pregnancy and during parturition.

Findings:

• Late-term MI and delivery proximity significantly elevate maternal mortality.
• Increased cardiovascular demands of pregnancy compromise women with ischemic heart disease.
• Myocardial oxygen demand/consumption must be managed throughout pregnancy, especially during labor.

Implications:

• High-risk patients necessitate individualized management by cardiologists, anesthesiologists, and obstetricians.
• Multidisciplinary team approach is crucial for optimizing outcomes in pregnancy-associated MI.
• Strategies to reduce myocardial oxygen demand are vital for maternal safety.
