Spontaneous coronary artery dissection.

Area of Science:

• Cardiology
• Vascular Biology
• Public Health

Background:

• Spontaneous Coronary Artery Dissection (SCAD) is an increasingly recognized cause of acute coronary syndromes, predominantly affecting younger women.
• It is characterized by a separation of the coronary arterial wall layers, leading to restricted blood flow and myocardial ischemia or infarction.
• SCAD is distinct from atherosclerotic dissections and often occurs in patients with minimal cardiovascular risk factors, leading to delayed diagnosis.

Purpose of the Study:

• To establish a collaborative partnership to advance research into SCAD.
• To create a European registry for SCAD patients to study epidemiology, management, and outcomes.
• To coordinate research, formulate consensus on diagnosis and management, and improve awareness and patient support.

Main Methods:

• Formation of a new Study Group within the Acute Cardiovascular Care Association (ACCA) of the ESC.
• Collaboration with the European Fibromuscular Dysplasia (FMD) Group.
• Establishment of a European registry for SCAD patients.

Main Results:

• SCAD diagnosis is frequently missed or delayed due to atypical presentations and lack of recognition of characteristic imaging findings.
• Management of SCAD differs significantly from atherosclerotic coronary disease, with lower revascularization success rates and challenges in long-term therapy.
• Recurrent SCAD is a significant concern, affecting up to 25% of patients over 5 years.

Conclusions:

• There is an urgent need for coordinated international research to understand SCAD's epidemiology, pathophysiology, and clinical management.
• The new SCAD Study Group aims to address this unmet clinical need by advancing research and improving care for SCAD survivors.
• Improved diagnostic accuracy and increased awareness are crucial for better patient outcomes.
