Abstract
Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of acute coronary syndrome (ACS) that usually presents in young female patients. Risk factors include female sex, physical and emotional stressors, and fibromuscular dysplasia, and diagnosis is usually made by coronary angiography aided by intravascular ultrasound (IVUS) or optical coherence tomography (OCT). While conservative treatment is usually preferred over percutaneous coronary intervention or surgery, medical management of SCAD has been under debate. This comprehensive review aims to summarize findings from recent studies exploring various medical treatment approaches for the management of SCAD. Antiplatelet therapy with aspirin is generally safe and beneficial for SCAD patients, with dual antiplatelet (DAPT) being recommended for patients undergoing PCI. In the absence of intervention, DAPT may be given for a short period followed by a longer single-antiplatelet (SAPT) therapy with aspirin. Beta-blockers appear to be safe and effective for SCAD patients. On the other hand, fibrinolytics, anticoagulants, and glycoprotein IIa/IIIb inhibitors are contraindicated. Cardiovascular medications such as renin-angiotensin-aldosterone system (RAAS) inhibitors, mineralocorticoid receptor antagonists, and statins are not recommended in the absence of left ventricular dysfunction. Hormonal therapy is contraindicated for patients who develop SCAD during pregnancy and future pregnancy is discouraged in that patient population.

Abstract
Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome (ACS) in young women who otherwise do not have traditional risk factors for coronary artery disease. Though previously considered to be a rare occurrence and primarily associated with pregnancy, contemporary series have demonstrated that SCAD may account for 35% of ACS in women under the age of 50 years, and peripartum SCAD accounts for the minority of cases. Importantly, an association between SCAD and arterial abnormalities in non-coronary arterial distributions has been described. The most common of these arterial abnormalities is fibromuscular dysplasia. This manuscript will briefly review the epidemiology, diagnosis, and treatment of SCAD and provide an overview of how SCAD may be a cardiac manifestation of an underlying vascular disease in the majority of patients.

Abstract
BACKGROUND Cardiac emergencies during pregnancy are rare but have significant associated morbidity and mortality when they do occur. The emergency physician must not only be aware of potentially life-threatening conditions in the pregnant woman, but also know the emergent management and treatment of these conditions to avoid worsening of the underlying condition. Pregnancy-related spontaneous coronary artery dissection has been described in the cardiology literature, but is not well-known in emergency medicine literature. CASE SERIES We present a case series of six previously healthy women ages 27 to 39 years who presented 1 to 75 days after delivery with spontaneous coronary artery dissection. The left main coronary was involved in 5 of 6 cases. One patient died, 5 survived. Two survivors maintained significant long-term disability. The patient that died had the diagnosis made on autopsy, the others were diagnosed with coronary angiography. Two patients were treated with stents, 2 with coronary artery bypass surgery, and 2 with medical management. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergent coronary catheterization is indicated if this diagnosis is suspected. However, emergency care teams must also understand how and why management including coronary artery catheterization can exacerbate the underlying condition. The role of coronary artery computed tomography remains unknown, although it exposes the fetus to significant radiation if the woman is still pregnant at presentation. Medical management is indicated with diffuse or distal disease as pregnancy-related coronary artery dissections often resolve with time. Localized discrete lesions may be stented. Coronary artery bypass graft surgery may be considered if the left main artery is involved or there are multiple proximal lesions. Cardiac transplantation is indicated rarely.

Abstract
OBJECTIVE Spontaneous coronary artery dissection (SCAD) is an under-recognised but important cause of myocardial infarction and sudden cardiac death. We sought to determine the role of medical and molecular genetic screening for connective tissue disorders in patients with SCAD. METHODS We performed a single-centre retrospective descriptive analysis of patients with spontaneous coronary artery disease who had undergone medical genetics evaluation 1984-2014 (n=116). The presence or absence of traits suggestive of heritable connective tissue disease was extracted. Genetic testing for connective tissue disorders and/or aortopathies, if performed, is also reported. RESULTS Of the 116 patients (mean age 44.2 years, 94.8% women and 41.4% with non-coronary fibromuscular dysplasia (FMD)), 59 patients underwent genetic testing, of whom 3 (5.1%) received a diagnosis of connective tissue disorder: a 50-year-old man with Marfan syndrome; a 43-year-old woman with vascular Ehlers-Danlos syndrome and FMD; and a 45-year-old woman with vascular Ehlers-Danlos syndrome. An additional 12 patients (20.3%) had variants of unknown significance, none of which was thought to be a definite disease-causing mutation based on in silico analyses. CONCLUSIONS Only a minority of patients with SCAD who undergo genetic evaluation have a likely pathogenic mutation identified on gene panel testing. Even fewer exhibit clinical features of connective tissue disorder. These findings underscore the need for further studies to elucidate the molecular mechanisms of SCAD.

Abstract
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction and sudden cardiac death. It occurs most commonly in otherwise healthy women during pregnancy or the postpartum period. The true incidence of SCAD is underestimated, as most cases are diagnosed at autopsy. The pathophysiology of SCAD is still not fully understood, and its management can be challenging. This report describes a 35-year-old pregnant female who presented with an acute antero-lateral ST elevation secondary to spontaneous dissection of the left anterior descending artery and the circumflex artery. The diagnosis was established by coronary artery angiography. However, the patient died following cardiac tamponade. The examination of this case represented a starting point for the reviewing of the diagnosis, clinical course, and management of SCAD, and for the placing of this in context with the existing literature. This study highlights the importance of prompt diagnosis and subsequent lifesaving treatment.

Abstract
BACKGROUND Spontaneous coronary artery dissection (SCAD) is an acute coronary event of uncertain origin. Clinical features and prognosis remain insufficiently characterized. METHODS AND RESULTS A retrospective single-center cohort study identified 87 patients with angiographically confirmed SCAD. Incidence, clinical characteristics, treatment modalities, in-hospital outcomes, and long-term risk of SCAD recurrence or major adverse cardiac events were evaluated. Mean age was 42.6 years; 82% were female. Extreme exertion at SCAD onset was more frequent in men (7 of 16 versus 2 of 71; P<0.001), and postpartum status was observed in 13 of 71 women (18%). Presentation was ST-elevation myocardial infarction in 49%. Multivessel SCAD was found in 23%. Initial conservative management (31 of 87) and coronary artery bypass grafting (7 of 87) were associated with an uncomplicated in-hospital course, whereas percutaneous coronary intervention was complicated by technical failure in 15 of 43 patients (35%) and 1 death. During a median follow-up of 47 months (interquartile range, 18-106 months), SCAD recurred in 15 patients, all female. Estimated 10-year rate of major adverse cardiac events (death, heart failure, myocardial infarction, and SCAD recurrence) was 47%. Fibromuscular dysplasia of the iliac artery was identified incidentally in 8 of 16 femoral angiograms (50%) undertaken before closure device placement and in the carotid arteries of 2 others with carotid dissection. CONCLUSIONS SCAD affects a young, predominantly female population, frequently presenting as ST-elevation myocardial infarction. Although in-hospital mortality is low regardless of initial treatment, percutaneous coronary intervention is associated with high rates of complication. Risks of SCAD recurrence and major adverse cardiac events in the long term emphasize the need for close follow-up. Fibromuscular dysplasia is a novel association and potentially causative factor.

Abstract
BACKGROUND Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome (ACS) that associates with a high acute-phase mortality rate, whereas long-term outcome is less well described. OBJECTIVE To describe the incidence, predictors, and prognosis of SCAD. DESIGN Retrospective case-identification study from the Western Denmark Heart Registry and the database of the Forensic Institute at Aarhus University from 1999 through 2007. RESULTS SCAD was documented in 22 of 32,869 (0.7 per thousand) angiograms in the angiographic registry. The SCAD incidence among cases of ACS was 22 of 11,175 (2.0 per thousand). None was seen in the forensic database. The mean age was 48.7 +/- 8.9 years (range: 37-71 years). Females constituted 17 of 22 (77%) patients and all had undergone one or more pregnancies; two cases occurred in the postpartum period. The left descending artery (LAD) was the predominant site of entry. The age distribution, prevalence of the cardiovascular risk factors, presence of coronary atherosclerosis, and entry of the dissection were comparable among genders. Treatment was percutaneous coronary intervention in 13 of 22 (59%), coronary artery bypass operation in 2 of 22 (9%), and medical treatment in 7 of 22 (32%) patients. The mean follow-up period was 3.6 +/- 2.9 years. One patient suffered from recurrent SCAD; another patient died suddenly. The MACE- (cardiac death, nonfatal myocardial infarction, and new revascularization) free survival was 81% after 24 months. CONCLUSION SCAD is a rare disease that mainly affects younger women. Compared with earlier reports, the prognosis seems to be improved by early diagnosis and interventional treatment.
