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.
