Insights
Spontaneous coronary artery dissection (SCAD) is a rare cause of heart attack, typically seen in women. This report details two asymptomatic SCAD cases discovered during routine preoperative assessments, highlighting unique diagnostic and management considerations.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Diagnostics
Background:
- Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia, often presenting with acute symptoms like angina or myocardial infarction.
- SCAD disproportionately affects women and is linked to autoimmune and collagen vascular diseases.
- Clinical outcomes and treatment strategies for SCAD are contingent upon the initial presentation and the dissection's severity.
Observation:
- This article presents two cases of SCAD that were incidentally discovered during routine preoperative evaluations.
- Both patients were asymptomatic at the time of diagnosis, underscoring the potential for silent SCAD.
- The cases highlight the importance of considering SCAD even in the absence of typical ischemic symptoms.
Findings:
- Asymptomatic SCAD can be diagnosed through routine preoperative screening.
- The diagnostic pathway for SCAD may differ in asymptomatic individuals compared to those with acute presentations.
- Early detection of SCAD, even when asymptomatic, is crucial for appropriate management.
Implications:
- Routine preoperative evaluations may identify asymptomatic SCAD, enabling proactive management.
- Understanding SCAD in asymptomatic individuals can refine diagnostic protocols and risk stratification.
- Further research is needed to establish optimal long-term management strategies for incidentally detected SCAD.
Abstract:
Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial ischemia that could present as angina, acute myocardial infarction, or even sudden death. It occurs more commonly in women and it has been associated with autoimmune and collagen vascular diseases. The management and prognosis in these patients depend on the initial clinical presentation and the extent of dissection. In this article, we report 2 cases of asymptomatic SCAD that were diagnosed on routine preoperative evaluation. The management options and clinical implications are discussed.
