  • Title: Spontaneous coronary artery dissection (SCAD): The underdiagnosed cardiac condition that plagues women.
    Author: Lebrun S, Bond RM.
    Journal: Trends Cardiovasc Med; 2018 Jul; 28(5):340-345. PubMed ID: 29275928.
    Abstract:
    Coronary heart disease (CHD) continues to be understudied, underdiagnosed, and undertreated in women. Gender and age bias complicate the evaluation of women with acute coronary syndrome (ACS). As a result, conditions like spontaneous coronary artery dissection (SCAD) are often missed. SCAD is an infrequent yet important cause of myocardial infarction (MI) with a predilection for young to middle aged women. The condition is thought to be under-reported, likely a result of both low index of suspicion as well as an unfamiliarity with SCAD's angiographic variants. Recently, the European Society of Cardiology (ESC) detailed an assessment pathway for patients with myocardial infarction with non-obstructive coronary arteries (MINOCA), a subset of which includes patients with SCAD. The pathway highlights the role of cardiac magnetic resonance (CMR) in addition to intracoronary imaging for increased diagnostic yield. Early and proper diagnosis is crucial in SCAD given the potential for sudden cardiac death, as well as the increased risk for future cardiac events including recurrent dissection. In addition, SCAD has frequently been associated with underlying connective tissue disease and/or arteriopathy, most commonly fibromuscular dysplasia (FMD), which requires careful screening. The lack of consensus on investigation or treatment highlights the need for increased awareness and further research to better understand this challenging entity.
