Spontaneous Coronary Artery Dissection of the Left Main Coronary Artery

Area of Science:

• Cardiology
• Vascular Biology

Background:

• Spontaneous coronary artery dissection (SCAD) is a critical cause of myocardial infarction, particularly in younger populations.
• SCAD is often misdiagnosed as gastroesophageal reflux disease or anxiety, leading to delayed treatment.
• While typically seen around age 45, SCAD can occur in younger individuals, posing a diagnostic challenge.

Observation:

• A young woman presented with symptoms suggestive of a heart attack.
• Electrocardiogram revealed ST-segment abnormalities and elevated cardiac markers.
• Coronary angiography identified a left main coronary artery dissection with thrombolytic extension.

Findings:

• The patient's young age is atypical for classical SCAD presentations.
• Left main coronary artery involvement is a critical finding, increasing the risk of adverse events.
• The dissection had a thrombolytic extension, indicating active clot formation.

Implications:

• This case underscores the importance of considering SCAD in young patients presenting with acute coronary syndromes.
• Advanced imaging techniques like coronary angiography are vital for accurate SCAD diagnosis.
• Complex SCAD cases may necessitate aggressive management, including coronary artery bypass grafting and potentially heart transplantation.
