[Spontaneous coronary artery dissection : primum nihil nocere]

Area of Science:

• Cardiology
• Vascular Biology
• Medical Diagnostics

Background:

• Spontaneous coronary artery dissection (SCAD) is a significant cause of acute coronary syndrome (ACS), myocardial infarction, and sudden cardiac death.
• SCAD disproportionately affects younger patients with few traditional cardiovascular risk factors.
• Historically underestimated, SCAD's prevalence has increased due to improved diagnostic methods.

Purpose of the Study:

• To highlight the growing understanding of SCAD as a distinct pathophysiological entity.
• To emphasize the differences in management and outcomes between SCAD and atherosclerotic ACS.
• To underscore the impact of recent advancements in SCAD diagnosis and research.

Main Methods:

• Analysis of data from large SCAD registries.
• Increased utilization of diagnostic coronary angiography.
• Application of intracoronary imaging techniques for diagnosis.

Main Results:

• SCAD is recognized as a unique condition, differing significantly from atherosclerotic causes of ACS.
• Diagnostic capabilities for SCAD have substantially improved.
• Knowledge regarding SCAD's distinct pathophysiology, management, and outcomes has expanded.

Conclusions:

• SCAD represents a critical, distinct cause of ACS, particularly in younger individuals.
• Effective management strategies for SCAD differ from those for atherosclerotic coronary artery disease.
• Continued research and registry data are vital for advancing SCAD patient care.
