Peripartum acute myocardial infarction: management perspective

Area of Science:

• Cardiology
• Obstetrics
• Perinatology

Background:

• Acute myocardial infarction (AMI) in pregnancy and puerperium presents significant maternal morbidity and mortality.
• While atherosclerosis can be a cause, many cases involve healthy coronary arteries, suggesting mechanisms like coronary spasm or thrombosis.
• Cardiovascular stresses increase significantly in late pregnancy and during parturition, posing risks for women with heart conditions.

Purpose of the Study:

• To highlight the importance of recognizing and managing acute myocardial infarction in pregnant and postpartum women.
• To discuss the underlying mechanisms and risk factors associated with AMI in this population.
• To emphasize the need for individualized, multidisciplinary care for high-risk patients.

Main Methods:

• Review of existing literature on acute myocardial infarction in pregnancy and puerperium.
• Analysis of potential etiological factors, including coronary spasm and thrombosis.
• Discussion of management principles and the role of multidisciplinary teams.

Main Results:

• Maternal mortality is substantial and increases with the progression of pregnancy, particularly during parturition.
• Reduced coronary perfusion due to spasm or thrombosis is a likely mechanism in cases with healthy coronary arteries.
• Early diagnosis and management are critical for improving outcomes.

Conclusions:

• Increased awareness and prompt diagnosis are crucial for managing AMI in pregnancy and puerperium.
• Limiting myocardial oxygen demand throughout pregnancy, especially during labor, is essential.
• Individualized care involving cardiologists, anesthesiologists, and obstetricians is necessary for these high-risk pregnancies.
