Insights
Spontaneous coronary artery dissection (SCAD) is an emerging cause of heart attack, particularly in young women. Understanding SCAD
Area of Science:
- Cardiology
- Vascular Biology
- Diagnostic Imaging
Background:
- Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome (ACS).
- SCAD disproportionately affects young women, often without traditional cardiovascular risk factors, suggesting unique pathophysiology distinct from atherosclerosis.
- This condition can lead to myocardial infarction and sudden cardiac death.
Purpose of the Study:
- To improve the characterization of SCAD prevalence, natural history, and clinical outcomes.
- To highlight the importance of intracoronary imaging in diagnosing and managing SCAD.
- To emphasize the need for considering SCAD in the differential diagnosis of ACS.
Main Methods:
- Review of current scientific evidence and clinical data on SCAD.
- Utilizing intracoronary imaging for enhanced diagnostic and therapeutic understanding.
- Analysis of pathophysiology, clinical presentation, treatment strategies, and follow-up.
Main Results:
- SCAD is more prevalent than previously estimated.
- Clinical management of SCAD differs significantly from atherosclerosis-related ACS.
- High risk of recurrence exists, especially in the early post-event period.
Conclusions:
- SCAD requires specific diagnostic and therapeutic approaches due to its distinct pathophysiology.
- Intracoronary imaging is crucial for accurate diagnosis and guiding treatment.
- Early identification of SCAD in ACS patients is critical for appropriate management and reducing recurrence risk.
Abstract:
Spontaneous coronary artery dissection (SCAD) has been recognized as an emergent cause of acute coronary syndrome (ACS), myocardial infarction, and sudden death. Patients mostly affected by SCAD are individuals without or with few cardiovascular risk factors, particularly young women, thus suggesting a clearly different pathophysiology than the more common atherosclerosis. Present research efforts outlined an improved characterization of the prevalence, natural history, and clinical outcome of SCAD. Intracoronary imaging has been an important asset in this condition, providing an improved diagnostic and therapeutic understanding. Current evidences suggest not only that this condition is more common than previously thought but also that the clinical management could be distinctly different from ACS secondary to atherosclerosis. Both medical and interventional treatment should consider the different cause of ACS, as well as the clinical stability of the patient, taking into account that the risk of recurrence is particularly high, predominantly during the first few days after the acute event. Stemming from new scientific evidences in terms of pathophysiology, clinical approach, therapy strategies, and follow-up of SCAD, it is important to identify spontaneous coronary dissection in the differential diagnosis of ACS.
