Insights
Spontaneous coronary artery dissection (SCAD) is a key cause of heart attacks in women. This review highlights SCAD in Asian women, emphasizing diverse presentations and diagnostic challenges.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Case Studies
Background:
- Spontaneous Coronary Artery Dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome (ACS), particularly in younger women without traditional cardiovascular risk factors.
- SCAD research has been predominantly Western-centric, leading to potential under-diagnosis and under-representation in Asian populations.
- Understanding SCAD's unique epidemiology and clinical manifestations in diverse ethnic groups is crucial for improving patient outcomes.
Observation:
- This review presents two distinct cases of SCAD in Singaporean women of Malay and Chinese descent.
- The cases illustrate that pregnancy-associated SCAD is not the sole or most frequent presentation.
- SCAD presentations are heterogeneous, and associations with connective tissue disorders like fibromuscular dysplasia warrant attention.
Findings:
- SCAD diagnosis remains challenging for many cardiologists, often requiring a high index of suspicion.
- Coronary angiography interpretation and the utility of intracoronary imaging are critical for accurate SCAD diagnosis.
- Effective management necessitates a multidisciplinary team approach and tailored recovery programs.
Implications:
- Increased awareness and research into SCAD in Asian populations are essential for enhancing diagnostic accuracy and treatment strategies.
- Developing specialized recovery programs incorporating support groups, allied health, and cardiac rehabilitation is vital for long-term patient well-being.
- Addressing the diagnostic and management complexities of SCAD can improve outcomes for affected individuals, especially in under-represented demographics.
Abstract:
Over the last decade, spontaneous coronary artery dissection (SCAD) has garnered much attention as a significant cause of acute coronary syndrome (ACS) and sudden cardiac death in women without classic cardiovascular risk factors. SCAD has been mostly studied in the West, with little recognition in Asia leading to under-diagnosis and under-representation. In this review, we highlight two distinct cases occurring at our center in Singapore, affecting two Singaporean women of Malay and Chinese descent. These 2 cases highlight that pregnancy-associated SCAD is neither the most common nor only manifestation of SCAD. Through review of the literature, we emphasize the heterogeneity in case presentation paying particular attention to SCAD and its association with connective tissue disorders such as fibromuscular dysplasia. SCAD remains a diagnostic challenge for many cardiologists, here we shed light and dispel myths surrounding coronary angiography and review the use of intracoronary imaging. The successful treatment of this unique group of patients requires a high index of suspicion, and management within a multidisciplinary team. The development of a recovery program with access to support groups, allied health, and cardiac rehabilitation is paramount in improving outcomes for these patients in the long term. Further research and studies in our Asian population will help to enhance our understanding of this disease and develop practices to best manage our patients.
