Spontaneous coronary artery dissection (SCAD) is rare, with variable causes and outcomes. This study highlights five diverse SCAD cases, showing unpredictable evolution and treatment responses.

Area of Science:

  • Cardiology
  • Vascular Biology
  • Medical Case Studies

Background:

  • Spontaneous coronary artery dissection (SCAD) is an uncommon condition with poorly understood incidence, etiology, pathogenesis, and optimal management.
  • Establishing definitive treatment protocols for SCAD remains challenging due to its rarity and variable presentation.

Observation:

  • Five cases of SCAD were identified from 2,241 coronary arteriograms (0.22% incidence).
  • Patient presentations ranged from acute myocardial infarction to unstable and effort angina.
  • SCAD was associated with coronary atherosclerosis in four cases; one patient had a seemingly healthy coronary tree.

Findings:

  • Treatment strategies included pharmacological management (3 patients) and surgical intervention (2 patients).
  • Angiographic follow-up (10-18 months) revealed varied dissection evolution: disappearance in three, persistence with obstruction in one, and progression in another.

  • Clinical follow-up (>20 months) showed no recurrence of symptoms in any of the five patients.

    • Implications:

    • These cases underscore the significant variability in SCAD's etiology, clinical course, and long-term evolution.
    • The diverse outcomes suggest that the underlying cause of medial hemorrhage in SCAD may differ, impacting treatment efficacy and prognosis.
    • Further research is needed to elucidate SCAD's pathogenesis and refine treatment guidelines.
