SCAD management requires a departure from standard ACS protocols, favoring a conservative initial strategy for stable patients and beta-blockers for secondary prevention.
Spontaneous coronary artery dissection (SCAD) is an increasingly recognized, non-atherosclerotic cause of acute coronary syndrome (ACS), particularly in younger women. This comprehensive review outlines SCAD's unique pathophysiology, which is linked to underlying arteriopathies like fibromuscular dysplasia, and highlights the critical role of advanced intravascular imaging for accurate diagnosis. A fundamental shift in management is detailed, with evidence favoring a conservative strategy for stable patients due to high rates of spontaneous vessel healing, reserving technically challenging invasive interventions for high-risk cases. Importantly, this review also addresses long-term outcomes, noting significant rates of recurrence and Major Adverse Cardiac Events (MACE), a high prevalence of persistent chest pain, and the central role of beta-blocker therapy in secondary prevention. Ultimately, SCAD requires a departure from standard ACS protocols towards a personalized approach that emphasizes accurate diagnosis, cautious initial management, and vigilant long-term follow-up.
